Post-Doctoral Fellows
Robin Welsh, Ph.D.
Dr. Robin Welsh received her Ph.D. in Immunology from Johns Hopkins University in 2021. As both a Post-doctoral Fellow and Doctoral candidate she worked in the laboratory of Dr. Scheherazade Sadegh-Nasseri focusing on the in vivo roll of an MHC Class II accessory protein, HLA-DO, on CD4+ T cell development and activation. In particular, she was interested on what impact loss of HLA-DO had on regulatory T cells.
Dr. Welsh also holds an M.Sc. in Molecular biology and a B.A. in Biology from Smith College. Working with Dr. Steven Williams, she investigated genetic changes in the filarial nematode B. malayi during the transition from the mosquito vector to a mammalian host. In Dr. Čiháková’s laboratory, she will be attempting to induce a more regulatory immune environment in the heart during both EAM and viral myocarditis thereby lessening disease severity. “
