Omer Weissbrod

I am a postdoctoral fellow at Alkes Price's group at Harvard University. My research lies at the intersection of machine learning, statistics and genetics.

Previously I was a postdoctoral fellow at Eran Segal's group at the Weizmann Institute of Science. I completed my PhD at the computer science department of the Technion under the supervision of Dan Geiger, and at the statistics department of Tel Aviv University under the supervision of Saharon Rosset.

I was also a part-time researcher at the Machine Learning for Healthcare and Life Sciences group at IBM Research Haifa, where I worked on a variety of projects involving analysis of genetic and clinical data.
