Leslie Beh
A.B. in Biology, Harvard University
A.M. in Biology, Princeton University
Ph.D. in Biology, Princeton University

Principal Investigator

Leslie earned an A.B. in Biology at Harvard University as a John Harvard scholar, where he trained with Nicole Francis to uncover sequence features underlying polycomb group protein activity. Under her tutelage, Leslie gained a lasting appreciation for biochemical approaches to understand protein function. He then completed an A.M. and Ph.D. in Biology from Princeton University with Laura Landweber and Tom Muir as a Petrie fellow, where he developed methods for assembling synthetic chromosomes with custom epigenetic modifications. Through genomics and biochemical fractionation approaches, he identified a novel DNA methyltransferase complex that is homologous to the RNA m6A methyltransferase, METTL3/14. Leslie then embarked on a short postdoctoral stint with Sam Sternberg at Columbia University, where he used genomic, structural, and biochemical approaches to study CRISPR-Cas systems that mediate RNA-guided DNA integration. Leslie then pursued a career in industry, joining Illumina to lead a research group for developing novel epigenetics assays. 

Leslie will draw upon his experiences from academia and industry to run a productive lab group at A*STAR / IMCB. Having personally benefited from good mentorship, Leslie cares deeply about guiding lab members towards their career goals and personal aspirations.
