      Collapse Overview
      Dr. Iryna V. Lobach earned 5-year diploma (equivalent to MS) from the Belarusian State University, Department of Applied Mathematics and Computer Science in 2001 and Ph.D. in Statistics at the Texas A&M University in 2006. Iryna joined UCSF after 2 years of postdoctoral training in statistical genetics at Yale University and 4 years of being a faculty member (Assistant Professor of Biostatistics) at the New York University.

      Currently Iryna is an Assistant Professor of Biostatistics. She conducts research in statistical methods for the analyses of the role of genetic and non-genetic factors in complex diseases. Iryna supports the biostatistics component of multiple biomedical studies through collaboration, consultation (CTSI biostatistics consultant) and mentoring (K-grants, mentoring in the Training in Clinical Research Program).
