Ethan Schonbrun received his Ph.D. from the University of Colorado at Boulder in electrical engineering, where he was awarded an NSF IGERT fellowship in Optical Science and Engineering. He wrote his doctoral thesis on light propagation in silicon photonic crystals, where he made some of the first measurements on negative refraction and near field imaging of Bloch waves. He then became a postdoctoral fellow in the School of Engineering and Applied Science at Harvard University, where he developed optical tweezers based on dielectric and plasmonic optical components. In addition, he became interested in the intersection of optics and microfluidics and the possibility of collecting images and spectra of populations of cells that would not be possible with classical microscopes. Following his postdoc, he received a Junior Fellowship at the Rowland Institute at Harvard and founded the Optofluidic Cytomtery lab. The group has developed new optical methods for extracting quantitative information about three dimensional morphology, protein mass, and molecular labels from individual cells in large populations. Using these systems, the group aims at developing deeper understanding of physiological functions on a cellular level using in vitro models. He has published 34 papers in international peer review journals, is a member of the Optical Society of America, and is a reviewer for several publications.
