He is also currently a resident in Pathology at UCSF. His research interests include epigenetic regulation of transcription and mechanisms of epigenetic inheritance. His aim was to leverage sequencing technologies to better understand how cellular diversity, development, and the response to stimuli are reflected in the transcriptome and epigenome. After finishing his PhD, he returned to complete med school at Johns Hopkins.

Tatiana Gelaf Romer

Tatiana Gelaf Romer was a biomedical engineering undergraduate from Dover, Massachusetts. Through her research, she’s hoping to get a better understanding of how we can study and manipulate genomes.
