Richard Isaac, PhD

Assistant Professor, Boston University Chobanian & Avedisian School of Medicine

Biography

Dr. Isaac's lab is focusing on the relationship between mitochondrial DNA packaging and expression and understanding the mechanisms that regulate the activity of this genome. Additionally, the lab interested in the structure and regulation of organellar genomes broadly, including those of chloroplasts and apicoplasts. The lab uses an multidisciplinary approach that combines genomics and bioinformatics, in vitro biochemistry, and molecular and cell biology to understand these biological processes.

He obtained his Ph.D. in the laboratory of Dr. Geeta Narlikar at the University of California, San Francisco studying how HP1 proteins play varied roles in heterochromatin establishment and maintenance. He was a postdoctoral fellow with Dr. Stirling Churchman at Harvard Medical School, where he developed mtFiber-seq, an approach that maps mitochondrial DNA accessibility across entire genomes at nucleotide resolution.
