November 12, 2018: Faculty of Science International Week Seminar

Date: Monday, November 12
Time: 1:30 pm
Location: Kresge Building, 106

Seminar Title: Plastic Here and Everywhere: International Effort in Fighting Plastics Pollution

Presenters: Anika Ballent and Patricia Corcoran

Abstract: Plastic is a relatively new material on planet Earth. In the short time it has been around, it has completely changed our world, for better or for worse. It is redefining many aspects of our lives, and affecting different cultures and regions in various ways. It is an issue that is tangible, urgent, and challenging, but we believe it is one that is possible to solve. Algalita works around the world engaging youth and communities in the plastic pollution problem. We've created a global network of environmental stewards working to address this issue in ways that work specifically for them. I hope to share our rounded perspective of the issue and to highlight the inspiring progress made by the people we've worked with from around the world.

Presenter Biographies

Anika Ballent, Education Director, Algalita Marine Research and Education (or just Algalita) Anika dove into the underwater world of plastic in 2010 when she was confronted by the images of plastic debris floating in the North Pacific gyre. She took the issue into her own hands and studied the underwater transport properties of plastics during her Bachelors of Science in Oceanography at Jacobs University in Bremen, Germany. She continued with a Master’s degree in Geology at the University of Western Ontario in Canada where she investigated microplastics in the sediments of the Great Lakes. As Education Director at Algalita, she guides youth through their own discoveries of plastic pollution and making real change in their communities. For Anika each day is an opportunity to make a positive impact in this world.

Patricia Corcoran is a sedimentary petrologist who studies how natural and anthropogenic processes affect Earth’s systems. She was the first scientific researcher to investigate plastics pollution in the Great Lakes, and her work concerning a new stone called plastiglomerate has been featured in various science and media outlets in North America, Europe, and Asia. She is currently the Chair of the Department of Earth Sciences at Western and when not in London, can be found in rivers and lakes and on beaches sampling for microplastics.

Examples of Funded Research Projects:

Space Astronomy: Nearby Galaxies Observed with Real and Virtual Telescope - Pauline Barmby

Understanding how galaxies work is part of knowing the origins of life on Earth. From the calcium in our bones to the North Star, the contents of our Milky Way galaxy are the product of earlier generations of stars. The processes that produced galaxies are so slow in human terms that the only way to see them operate is to run computer simulations. Prof. Pauline Barmby’s research will determine how well simulations reproduce real galaxies, using the world's most advanced telescopes to make observations of nearby galaxies.

Space Physics: Weather - Radar applications to studies of winds & severe weather – Wayne Hawking

Physics professor Wayne Hawking’s project focuses the role of the middle atmosphere in space travel and the accurate predication of sever weather events at the surface. Space craft must be launched through the middle troposphere, stratosphere and mesosphere in order to reach space, and the winds, temperatures, turbulence strengths, buoyancy wave composition and general atmospheric structure in this region must be well understood in order to make safe launches. Recent interest in commercial spaceflight (e.g. SpaceX), including plans to fly between continents through lower space, have made real-time prediction of middle atmosphere conditions vital.

Meteor Physics: Structure, Composition, and Origin of Meteoroids - Margaret Campbell-Brown

Millimeter-sized pieces of dust from comets and asteroids have changed very little since they condensed out of the solar nebula before the planets formed, and their structure and composition tell us about the origin of our own planet. Meteoroids in this size range also pose a threat to spacecraft, including crewed missions. The slowest meteoroids travel much faster than bullets and have incapacitated spacecraft in the past.

Campbell-Brown’s research will determine where most meteoroids come from and how dangerous they are to spacecraft. She will also look at meteor shower activity to better predict when spectacular (and potentially dangerous) outbursts may occur. Meteors which don't belong to showers may be tens or hundreds of thousands of years old and give us a window into the past activity of comets and asteroids in our neighbourhood. These small objects are also much more numerous than shower meteors, and so pose the most risk to spacecraft. Her research will report on how the activity of these meteors changes with time. Finally, Campbell- Brown will build models of what happens to a meteoroid in the fraction of a second before it is vaporized in the atmosphere to help us understand what the parent asteroids and comets are made of, and how they formed.

Climate Change: Climate change and catchment controls on the mercury cycle – Brian Branfireun

The lack of knowledge about the controls on the delivery of Mercury (Hg) to aquatic food webs is particularly problematic when attempting to forecast the impacts of climate change on the Hg cycle. Branfireuns’s research will quantify the gaseous Hg uptake by plants, as well as the highly toxic Methylmercury (MeHg) inputs to boreal sub-arctic soils. This project will also clarify the role of drainage basins as a source of MeHg to boreal sub-arctic freshwater lakes and identify how the quality of northern dissolved organic matter mediates the assimilation of Hg and MeHg by phytoplankton.

Agricultural Sustainability: Plant-herbivor interactions -Vojislava Grbic

Agricultural super pest, the spider mite, feeds on over 1100 plant species including more than 150 crops worldwide. With increased reproductive potential under conditions of global warming, combined with an outstanding ability to adapt to new crops and develop resistance to pesticides, the spider mite threatens global crop security. Vojislava Grbic’s research will determine how Arabidopsis plants establish defenses in anticipation of spider mite feeding. In parallel, it will identify spider mite counter-adaptations to Arabidopsis defenses. This research will establish an unprecedented level of understanding of plant-herbivore interaction. The knowledge of plant defense mechanisms will lead to the development of new control strategies against this important agricultural pest, while mechanisms of mite counter adaptations will help maintain the efficacy of these control strategies in agricultural practices.

Ecological Sustainability: Biology of Fear – Liana Zanette

Humans are both “super predator” and prey – inducing fear in other animals and fearing them in turn. Our role as predator is revealing the central importance of predator-induced fear in ecology; recognizing our role as prey is enhancing our understanding of post-traumatic stress (PTSD); and measuring the fear we inspire may provide a tool to gauge our impacts on the environment, and so aid conservation. Frightening prey to death, e.g. by impairing parental care, has been argued to be part of the critical ‘ecosystem service’ large carnivores provide, in keeping their large herbivore prey in check; a service being lost with the loss of large carnivores caused by their persecution by the human “super predator”.

Biology professor Liana Zanette’s project will first test how the fear of large carnivores impacts the demography and behaviour of their large herbivore prey in two parallel experiments, on deer on B.C.’s Gulf Islands, and ungulates (e.g. wildebeest) in South African game reserves. Predator induced fear is now one of the most common stressors used in ‘animal model’ (lab rat) studies of PTSD, because it produces effects on the brain matching those seen in PTSD sufferers. Zanette will also test for comparable lasting impacts of fear on the brain in wild animals. Large carnivores have come to so fear the human “super predator” this can affect their keeping large herbivores in check, and result ecosystem-level impacts. Humans are definitely a predator, poaching being a principal cause of biodiversity loss. Quantifying poaching presently relies upon questionnaires, which are intrinsically unreliable because respondents must to confess to crimes. Animals know their enemies. Therefore, Zanette will test whether ‘interrogating’ wildlife about their fear of humans, and using innovative new technology, can be used as a tool to reliably gauge the impacts of poaching, and ecotourism.

Alternative Energy: Nanoscale Electrochemistry, Spectroscopy and Microscopy – Zhifeng Ding

Among all alternative energy sources, solar energy is clean and the most powerful. The sun-light on earth has a huge capacity to match our total world oil reserve of ~3 trillion barrels with 1.5 days of irradiation. However, the solar approach currently supplies only 0.015% of our electricity globally. Ding’s research aims to enhance the efficiency of low-cost, light-weight thin film Cu2ZnSnS4 (CZTS) solar cells. More than 10% efficiency is anticipated.

Materials Science: Transformative Strategies for the Production of Hybrid L – Joe Gilroy

As the technological demands of our country continue to evolve, so does the need for innovative and readily accessible functional materials. Joe Gilroy’s project will focus on the production of luminescent and semiconducting molecular, polymeric, and self-assembled materials for use in a variety of organic electronics (e.g., sensors, memory devices, light-emitting diodes, field-effect transistors, and solar cells).

Medical Application of Big Data Analytics: Machine learning methodology for sequential decisions - Dan Lizotte

Making good decisions in the present often requires knowledge of potential decisions to be made in the future. Consider choosing a medical treatment for a patient with a chronic disorder: in practice, treatment decisions are made based on knowledge about the state of the patient, knowledge about the treatment options currently available, and knowledge about how future decisions will be influenced by the patient's progress over time. The development of electronic data sources that record how thousands or even millions of patients respond to different sequences of treatments over time, have the potential to inform evidence-based medical decision making more effectively than ever before. However, rigorous analysis techniques for extracting evidence from this data and effectively presenting it to physicians -- for example through personalized treatment recommendations -- are still in their infancy. Dan Lizotte’s research aims to adapt and improve reinforcement learning and machine learning techniques so they can be applied to these new sources of sequential medical data and can in turn provide doctors with the best available evidence to aid them in choosing the best treatments for their patients.

Western Hosts First Annual Fields Summer School on Topological Data Analysis for Banking and Finance

Western’s School of Mathematical and Statistical Sciences (SMSS), in collaboration with the Fields Institute for Research, hosted 50 participants during its first annual Fields Summer School on Topological Data Analysis for Banking and Finance. Students and Postdoctoral Fellows from across the nation and several international destinations including the UK, Korea and the US participated in three inter-related short courses as well as authentic problem-solving challenges over a two-week period.

Participants learned the fundamentals of topological data analysis, developed a greater awareness of data available for banking and financial analysis and explored the use of programming tools for bank and finance analytics.

“Student growth was impressive as they adapted new analytical techniques to data sets, eventually leading to actionable business insights,” commented SMSS founding director and dean of the Faculty of Science, Matt Davison.

The success of the summer school was due in part to the active participation of Scotia Bank, which provided synthetic anti-money laundering data, and through the on-site engagement of Rene Stock, Andi Moshirvaziri, Yousef Akhavan and Inshu Bhatnagar, delivered presentations, offered insightful feedback and shared their front-line expertise. Other individual collaborators, including Data Engineer Charlie Frantowski, also played an important role, imparting their significant understanding of the corporate challenges of data storage, security and application.

2018 Paul De Mayo Award: Stephanie Barbon

Dr. Stephanie Barbon awarded the Paul De Mayo award for her outstanding research pertaining to chemical bonding and control sequencing in polymers.

There’s an undeniable celebratory energy inside the venue. This is a victory lap of sorts for one of Western’s most promising recent graduates.

Earlier, I had the opportunity to sit down with Stephanie and find out a bit more about this outstanding representative of the science community.

“I grew up in London, so it always made sense for me to study here.”

Stephanie lived the London dream, choosing to go to Western for her undergraduate and eventual doctoral studies. After seven years at Western and with only a year and a half remaining in her doctoral studies, a captivating guest lecture, from superstar chemist Craig Hawker, prompted her to send him an email, asking if he had a spot for her in his lab at the University of California, Santa Barbara. Hawker took a look at Stephanie’s academic record – there was no question that he could find her a spot.

“Craig has a really big reputation in our field of research and is an extremely impressive guy. I jumped at the opportunity to work with him. It’s always tough to be away from your family, but it’s been a fantastic place to live and a thrilling place to do research. I’m learning lots.”

Stephanie enrolled at Western as a chemistry major in 2011, but it wasn’t until a second-year research project in Newfoundland where she found her true passion: polymers.

“We were generating polymers with catalysts. I realised that I was much more interested in the polymers that were being created, rather than what was creating them. Ever since then, I’ve been engrossed in the study of polymers.”

Stephanie’s research focuses on creating the synthetic replication of molecules that control our cellular processes and initiate the reactions that occur in living cells.

"Historically, polymers have just been a single molecule repeated along a lengthy chain. What we’re working on, is being able to control the order of the molecular structure. If you think of a protein, you can control which amino acids are next to each other. Our goal is to be able to replicate that process in synthetic polymers too. We want to be able to control the properties very finely, based on the order that they’re in.”

Stephanie wants to unlock new functions for materials that have never gone through the chain-like chemical bonding process known as polymerisation.

“I’m working with polymerising new materials. Specifically, materials that could be useful for a variety of applications that we haven’t been able to access yet. I’m also looking at anti-bacterial polymers. Hospitals need anti-bacterial coating for everything to reduce the spread of bacteria. A lot of the coatings that have been developed in the past are peptide- (small proteins) based. Peptides are expensive and difficult to make, so we think that if we can replicate this process with polymers, then it’s going be a lot easier to scale up, make big batches and coat the whole hospital both effectively and in a less expensive fashion.”

If it sounds ambitious, that’s because it is. The complex functions that polymers such as protein and our own DNA provide, make up the very fabric of who we are.

“Proteins have very specific functions based on the way they orientate, and so if we can control the way that polymers combine, we may produce some naturally occurring functions in synthetic polymers.”

This research led Stephanie to be selected for the Governor General’s Gold Medal for Academic Excellence and the aforementioned ‘Paul De Mayo Award’. Notably, the ‘Paul De Mayo Award’ aims to recognize a graduate student who not only excels in their own research, but helps breed a culture of critical thought and scientific excellence within the Department of Chemistry. It comes by no surprise that Stephanie won this award considering her engagement in public outreach.

Employee of the year in 2015, Stephanie beams when recalling her time visiting elementary schools, setting up booths at community events and brainstorming science activities. She embodies the “pay it forward” concept with the way in which she approaches teaching and sharing science knowledge.

“I had a lot of awesome teachers in elementary and high school, who fuelled my interest in science. If I can do the same thing for one person, then it’s worth all the effort.”

What’s next for Stephanie in her scientific endeavours? First, she will be completing the second year of her two year fellowship at Santa Barbara. After that, it’s time to come home.

“I aspire to end up back in Canada. That’s my goal. California’s nice but it’s not home. I will be back.”


Fun with Main Group Chemistry

The Ragogna Research Group

The main group elements, a sub-group of the iconic Periodic Table of the Elements, have long been the vanguard for establishing parameters for principles of chemical structure (molecular shape) and bonding (forces holding atoms together). A main group chemist often tries to push the boundaries of established rules for structure and bonding, which makes the research area both interesting and frustrating.

Chemists working with compounds derived from this part of the Periodic Table have not only made ground-breaking, fundamental discoveries (e.g. Noble Gas compounds), but have also generated new materials that are of immense practical benefit to humanity (e.g. Silicone polymers).  Since 2005 our group has spent considerable effort investigating the fundamental chemistry the main group elements, and although we cannot lay claim to such impactful discoveries such as silicones, we do indeed look to discover applications for our new knowledge.  In this context, key fundamental discoveries that have emerged from our lab and the spin-off, industrially-relevant research will be highlighted.  Most importantly, the lecture will be a tribute to the clear dedication, skill, and tenacity of the many undergraduate and graduate students and postdoctoral researchers that have passed through the Ragogna Group laboratories.  As we all know, without such a team, none of the discoveries would have come to fruition.

Western University's Three Minute Thesis Winner

Image of Western Science's 3MT competitors, including Tianqi

Western Science's 3MT finalist, Tianqi Xie is second from the right.

Tianqi Xie, Western University’s 2018 winner of the campus-wide Three Minute Thesis Competition, is on a journey to unlock the secrets of the Moon. Through her research, she dives into the explosive history that shaped our closest neighbor, trying to understand how it’s surface evolved over billions of years.

We’ve all seen a full Moon on a clear night, some of us might have even been fortunate enough to catch the “Super Moon” this past year, but if you’ve ever looked at a snapshot of the Moon you will see thousands of circular, bowl-shaped features covering the surface. They can range from a few meters to hundreds of kilometers wide. Called impact craters, these geologic landmarks are formed by the collision of material whipping around in space at kilometer per second speeds, often ten times the speed of most bullets.

When rocks collide at these speeds, a catastrophic explosion results. The impactor is vaporized in seconds and the bodies that have been hit are fundamentally changed. When these collisions unfold on the Moon, solid rock is instantly turned into liquid, molten material. Even more material is displaced, ejected, and thrown across the surface. The energy of the impact unleashes a shockwave several times greater than those experienced during the nuclear testing of the Cold War. It is how this shockwave travels through solid material that Tianqi is most interested.

The analytical system Tianqi uses to do her research is called Raman spectroscopy. This non-destructive technique is commonly used to identify organic and inorganic material in geologic samples. In NASA's upcoming Mars 2020 mission, a Raman spectrometer will be used to try and find evidence for life on the Martian surface.

Tianqi is one of the few people in Canada who gets to hold pieces of the Moon and explore its crystalline structure by shooting lasers at them. By looking characteristic pattern returned from this shocked lunar material, Tianqi examines how the structure of the material has changed, what pressures the material experienced, and how proximal was the material from ground zero of the impact. In doing so, she hopes that we can better understand this geologic process, which has shaped every planetary body in our Solar System.

After finishing her BSc and MSc in Beijing, she became part of the Western Science community in the fall of 2014 as she started her PhD. Whether it's catching a new play or her Flamenco lesson, she has found time to take in the rich culture around her. Tianqi has loved her time in Canada. She hopes to pursue an academic career here in Canada, but she is certainly open to exploring and discovering new destinations as her career takes off.


The Three Minute Thesis Competition

The 3MT (Three Minute Thesis) competition asks graduate students to present the breadth and significance of their thesis in 1 slide and 3 minutes to do just that to a non-specialist audience. This fun and challenging academic competition gives Western Science graduate students the opportunity to improve their communication skills while potentially winning a first place prize of $1000. 

The 3MT Competition was originally developed by The University of Queensland, Australia, but since then, it has become a truly international phenomenon with global competitions held each year. The exercise develops the ability to effectively communicate complex research using open language, allowing you to explain the significance of your research to your peers and the wider community.

2018 C. Gordon Winder Memorial SCUGOG Public Lecture

Join us for the 2018 C. Gordon Winder Memorial SCUGOG Public Lecture given by Dr. Natalya Gomez.

Dr. Gomez is the Canada Research Chair in ice sheet - sea-level interactions at McGill University and will be giving a talk on Ice, Sea Level, and the Solid Earth. An abstract and Dr. Gomez's biography can be found below.

The talk will be Thursday, February 1st, 2018 at 7:00 pm in Middlesex College, room 110. A reception will follow.

Ice, Sea Level, and the Solid Earth

Sea-level rise is projected to displace communities around the world in the coming centuries, and the melting of the polar ice sheets is expected to make a significant contribution to the rising water levels. In particular, recent research suggests that unstable, runaway retreat may already be underway in certain sectors of the Antarctic Ice Sheet. A critical task of climate change research is to understand the response of present-day ice reservoirs to climate warming and estimate their contribution to future sea-level rise. In this talk, I will discuss the stability and evolution of the polar ice sheets, the physics of the associated sea-level changes, and the role that the solid Earth plays in these changes.

Natalya Gomez's Biography

Natalya Gomez is an assistant professor in the Earth and Planetary Sciences Department at McGill University and a Canada Research Chair in the Geodynamics of Ice Sheet - Sea Level interactions. She works at the intersection between two rapidly progressing areas of research: Solid earth geophysics and climate science. Her research centers around modeling the interactions between ice sheets, sea level and the solid Earth and understanding how these earth systems evolve in response to past, present and future climate changes in regions such as Antarctica, Greenland, North America and the Arctic. A highlight of her work has been to identify and quantify a previously neglected feedback between sea level changes and ice sheet dynamics. Her approach to modeling this sea level feedback has been adopted by groups around the world to study a wide range of problems in paleo, modern and future climate change. She has recently applied the approach to demonstrate the potential importance of local sea level changes and variations in Earth structure on ice-sheet evolution and the interpretation of geologic and geodetic records in Antarctica. She is also interested in the implications of climate change for coastal communities and environments in the Canadian Arctic.
