Ignaty Leshchiner, PhD

Assistant Professor, Boston University Chobanian & Avedisian School of Medicine

Biography

Dr. Leshchiner is interested in applying new genomic technologies such as blood biopsy, long-range read phasing, and single cell sequencing for analysis and understanding of biology behind tumor development, treatment evasion, and progression to metastasis. His background is in developing statistical methods for analysis of genomics data and application of these methods to understanding biology and finding treatment for various disease conditions.

Prior to joining Boston University, Dr. Leshchiner served as the associate director of the Computation Biology and Cancer Resistance Department of the Broad Institute of MIT and Harvard. He remains a member of the institute's affiliated faculty. Leshchiner also worked for Partners Healthcare as a bioinformatician in the genetics division of Brigham and Women’s Hospital, where he contributed to the CLARITY Challenge-winning team in 2012. He has previous consulting experience for Hybrid Silica Technologies and prior research fellowships at UMass Lowell and Moscow State University.

Dr. Leshchiner obtained a Ph.D. in chemistry from Moscow State University, which included a visiting scientist appointment in the Langer Lab at MIT. He completed postdoctoral training in bioinformatics and computational biology at Harvard Medical School.
