Research Interests & Projects

Andrews Research Group
Active and past projects include parameter estimation algorithms, software development in R, robust variable selection, and applied projects in engineering, biology, ecology, health and physics.

Undergraduate Research Assistants
Undergraduate students interested in summer research opportunities are encouraged to discuss in person. Completion of 3rd year in Math/Statistics/Computer Science/Data Science, including strong performance in Machine Learning (DATA 311) is generally a pre-requisite for fruitful summer projects — but exceptions may be possible.

Graduate Supervision
Prospective students must meet program eligibility requirements with excellent performance in upper-year mathematics/statistics courses, ideally including a course in multivariate statistics/machine learning. Research experience at the undergraduate level is an asset. Proficiency in scientific writing, R (and/or general computer programming), and LaTeX document preparation are also assets. Graduate award applications to NSERC CGS are encouraged — these generally have internal deadlines at the university you are graduating from and it is advantageous to discuss potential projects ahead of time. Teaching assistantships and other sources of funding are available for qualified incoming grad students.
