What is an Actuary?

The future is full of uncertainty. Some of the events that can happen are undesirable. "Risk" is the possibility that an undesirable event will occur. Actuaries are experts in:

  • evaluating the likelihood of future events
  • designing creative ways to reduce the likelihood of undesirable events
  • decreasing the impact of undesirable events that do occur

The impact of undesirable events can be both emotional and financial. Reducing the likelihood of these events helps relieve emotional pain. But some events, such as death, cannot be totally avoided. So, reducing their financial impact is very important. Actuaries are the leading professionals in finding ways to manage risk. It takes a combination of strong analytical skills, business knowledge, and an understanding of human behaviour to design and manage programs that control risk.

Who do actuaries work for?

  • Insurance Companies
  • Investment Firms
  • Trust Companies/Banks

What is Data Science?

Data science refers to the development and application of methodologies for inspecting, cleaning, managing, transform, visualizing and modeling data with a view to discovering useful information, reaching conclusions and supporting decision making.  Data Science is inherently interdisciplinary, with the two dominant disciplines being Computer Science and Statistical Science.

There is a big demand for Data Scientists and that demand is still growing as the rate of data collection is increasing in every discipline. Being able to efficiently generate, manage and analyze digital information, data scientists are widely sought after in numerous fields of scientific investigation.

What is Financial Modelling?

Over the past two decades, new quantitative techniques have transformed the investor decision-making process and the financial industry. Today, banks, insurance companies, securities, and investment firms turn to technical innovation to gain the competitive advantage. Sophisticated mathematical models are used to support investment decisions, to develop and price new securities, or to manage risk.

Financial institutions, in addition to energy companies, utilities, and corporations with exposure to exchange rate or commodities risk, are hiring quantitatively sophisticated employees.
