Iuliana Ionita-Laza, PhD

  • Professor of Biostatistics
Profile Headshot

Overview

My main research interests lie at the interface between statistics and genomics. I am particularly interested in developing statistical and machine learning methods for the analysis of high-dimensional genetic and functional genomics data. I am also involved in applications of such methods to understand the genetic basis of complex diseases and traits, including autism spectrum disorders, schizophrenia and Alzheimer's disease.
