Tomokazu S Sumida, MD, PhD

Dr. Tomokazu Sumida received his MD from Chiba University School of Medicine in Japan in 2004 and completed two years of residency, followed by two years of fellowship in cardiology. He practiced as a cardiologist in Japan before obtaining his PhD in 2012 studying the interface between the immune system and cardiovascular disease. To learn basic and translational immunology, he joined the lab of Dr. David Hafler at Yale in 2015 as a postdoctoral fellow. His research focus is mainly on understanding molecular mechanisms that drive T cell dysfunction, especially regulatory T cells, in human diseases by using cutting-edge technologies (i.e. Single-cell multi-omics, ATAC-seq, CRISPR gene editing/regulation). He was appointed as an assistant professor of neurology in 2020.
