Research Summary
Dr. Kozal is a translational researcher who has focused his research career on three areas: 1) investigating the genetic determinants of HIV and HCV drug resistance, 2) the development of new molecular methods to detect viral mutations, and 3) HIV and HCV clinical trials involving new drugs and diagnostic technology. Dr. Kozal is an expert in microarray and deep sequencing technology receiving patents for his work in genotyping. Dr. Kozal previously directed the Yale HIV Clinical Trials Group and has more than 20 years of experience in running clinical trials, serving as the principal investigator or site investigator on >40 HIV and Hepatitis C trials.
