Dr. Greenwood is a Professor jointly appointed between Oncology and Epidemiology, Biostatistics and Occupational Health, and Senior Scientist in the Cancer Research Axis of the Lady Davis Institute at the Jewish General Hospital. She is one of the Scientific Directors of the Ludmer Centre for Neuroinformatics & Mental Health at McGill University and is also the inaugural Graduate Program Director of McGill's new interdisciplinary Quantitative Life Sciences ad hoc PhD program. This new graduate program is one of three in McGill's Interfaculty Studies and draws supervisors from multiple faculties (Medicine, Science, Engineering, Dentistry, and Agriculture & Environmental Sciences).
Her research focus lies in the development of methods for analysis of genetic and genomic data. Specifically, she is working on methods for analysis of epigenetic data, using local smoothing combined with approaches for analysis of correlated count data. She is interested in estimation of significance thresholds in large scale experiments such as genome-wide association studies of sequenced or imputed genetic data. She is also involved in development of analytic approaches for high dimensional data. Her collaborators work in cancer, rheumatic disease, disease of aging, and many other domains.
