Christopher John Frederick Cameron, PhD

1 Simons Electron Microscopy Center, New York Structural Biology Center (NYSBC)

As a computational biologist, I develop novel statistical, machine learning and bioinformatics approaches to emerging molecular biology technologies. At NYSBC, I build new computational methods to improve the center's cryogenic electron microscopy (cryo-EM) and other structural biology pipelines. My postdoctoral research focused on cryo-EM image processing, specifically addressing the modeling and integration of prior information. During my PhD, I implemented analyses of chromosome conformation capture and chromatin immunoprecipitation data that provided insight into the regulation of genomes through the organization of chromatin’s higher-order structures.

Keywords: computational biology, machine learning, cryo-EM, 4D regulatory genomics
