Omer Weissbrod

About me

I am currently a postdoctoral fellow at Alkes Price's group at Harvard University. My research lies at the intersection of machine learning, statistics and genetics. Specifically, I am interested in applying Gaussian processes and graphical model techniques for the analysis of large high-dimensional genetic data.

Before that 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. My PhD thesis tackled complex problems in statistical genetics, using advanced methods from machine learning and statistics.

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.
