Professor Jacek Majewski received a PhD in Evolutionary Biology from Wesleyan University (1999), a Master’s in Electrical Engineering from Stanford University (1991) and a Bachelor in Physics, also from Stanford (1990). He is Associate Professor, Department of Human Genetics, Faculty of Medicine at McGill University and holds the Canada Research Chair in Statistical Genetics. Prof. Majewski’s research is based on genomics and bioinformatics analysis of high throughput data. The recent revolution in massively parallel DNA sequencing has opened new venues into numerous biomedical problems.

My group specializes in the analysis of high throughput genomics data, with specific applications to human hereditary disease and cancer. My diverse background combining quantitative sciences and biology has become a strong asset in the era of big data in biology. I have a long history of leading projects both as a PI and collaborations in large teams. My participation in collaborative teams resulted in over 200 publications utilizing high throughput sequencing approaches in genetics of disease, cancer, and basic biology My current interests focus on the role of epigenetic dysregulation in cancer. In order to better understand disease states, we have also ventured into exploring the balance of chromatin modification during normally progressing development. As the next frontier, we are also working on integrating classical epigenetic approaches with chromatin conformation data and developing methods to visualize and analyzed chromatin in a three dimensional framework.
