Timothy J. Stasevich is an Assistant Professor in the Department of Biochemistry at Colorado State University (CSU). His lab uses a combination of advanced fluorescence microscopy, genetic engineering, and computational modeling to study the dynamics of gene regulation in living mammalian cells. Most recently, his lab has pioneered the imaging of real-time single mRNA translation dynamics in living cells [1]. Dr. Stasevich received his B.S. in Physics and Mathematics from the University of Michigan, Dearborn, and his Ph. D. in Physics from the University of Maryland, College Park. He transitioned into experimental biophysics as a post-doctoral research fellow in the laboratory of Dr. James G. McNally at the National Cancer Institute. During this time, he developed technology based on fluorescence microscopy to help establish gold-standard measurements of live-cell protein dynamics. Dr. Stasevich next moved to Osaka University, where he worked with Dr. Hiroshi Kimura as a Japan Society for the Promotion of Science Foreign Postdoctoral Research Fellow. While there, he helped create technology to image endogenous proteins and their post-translation modifications in vivo. This allowed him to image the live-cell dynamics of epigenetic histone modifications during gene activation for the first time [2]. Before joining the faculty at CSU, Dr. Stasevich took a one year hiatus at the HHMI Janelia Research Campus, where he further improved the spatio-temporal resolution of endogenous protein imaging in live-cells.
