Ethan Schonbrun received his Ph.D. from the University of Colorado at Boulder in electrical engineering with Professor Won Park through 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 moved to Harvard University to study nano- and microphotonics with Professor Ken Crozier. As a postdoc, he became interested in the intersection of optics and microfluidics and the possibility of capturing 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 started 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, holds seven patents, is a member of the Optical Society of America, and is a reviewer for several publications.
