Sahir Rai Bhatnagar
Assistant Professor, Biostatistics, McGill University.
I am an Assistant Professor in the Department of Epidemiology, Biostatistics and Occupational Health, and the Department of Diagnostic Radiology at McGill University. I am broadly interested in developing statistical methods for high-dimensional data using penalized regression methods. My current work is focused on penalized mixed models and non-linear interactions. I previously developped a methodological approach for identifying clusters of features that are sensitive to environmental exposures. I'm also interested in survival analysis methods, interactive plots, and reproducible research.
Research Opportunities
I have opportunities for graduate and undergraduate students to assist with various research projects. Please contact me to learn about specific research and training opportunities.
