The Canadian Network for Aquatic Ecosystem Services, for which Irena is a theme co-leader, is looking for PhD students to start in 2013 and 2014. There are 10 PhD positions available to be hosted at UBC, Western, Guelph, Trent and UNB.  Projects will use GIS, remote sensing, modeling, scenario analysis, laboratory and field techniques to investigate the relationship between forests and aquatic ecosystem services. Take a look at this advertisement for more information [PDF].

Jackie won an Alexander Graham Bell Canada Graduate Scholarship from NSERC. Congratulations Jackie!

Irena wrote on Op-Ed for World Water Day. Take a look here [PDF].

Irena's paper on Hydrologic Profiling has been accepted by the Journal of Geophysical Research: Biogeosciences and will be featured as in an EOS "Research Spotlight." We'll post the finished products once they're ready.

The Canadian Network for Aquatic Ecosystem Services, for which Irena serves as a theme co-leader, has been publicly announced, including a feature in the Western News. This NSERC Strategic Network Grant brings together researchers from across the country to study the benefits of and threats to the ecosystem services provided by aquatic ecosystems. Congratulations to Irena and everyone who worked so hard to bring this together!

Irena has been awarded a Female Guest Professorship at Umea University in Sweden. She will spend up to nine months at Umea over the next three years at the Department of Ecology and Environmental Sciences. [Western News] 

Irena is on a research sabbatical from July 2012 to June 2013 and is out of the country from January to June 2013.

Katrina won First Prize at Western's Postdoctoral 3 Minute Research Presentation Competition. Congratulations Katrina!

Irena gave two invited talks at the Fall AGU meeting in San Francisco. [PDF], [PDF]

Our work on the Ecosystem Services Pilot Program was nominated for the Outstanding Achievement Award from the Alberta Sustainable Resource Development Corporate Award. Thanks to Dave Aldred and Adam Spargo for all the hard work that led to this honour!

Irena's Canada Research Chair in Watershed Sciences was renewed. Congratulations Irena!

Ryan gave a talk at ASLO in Japan. [PDF]

The Great Lakes Futures Project has been receiving quite a bit of press lately (Western, Hamilton CBC, Associated Press, Science Daily and more). Katrina has become quite the media darling!  

Sami's paper on stationary and non-stationary signals in water yields has been published in Hydrological Processes. [PDF]

RESEARCH GOALS

Our research characterizes watershed processes through innovative techniques in GIS, remote sensing and modelling. We conduct science that tracks the movement and fate of nutrients within and through watersheds, which are released to the atmosphere and aquatic systems.

We work with a global network of scientists focused on discovering watershed responses to global change and extending watershed research into more broad and integrative disciplines like ecosystem health and ecosystem services.

PROSPECTIVE STUDENTS AND EMPLOYEES

Please send a curriculum vitae and short description of your research experience and interests to icreed@uwo.ca.
