Bachana Lomsadze received his Bachelor’s degree in physics from Tbilisi State University (Georgia) in 2007 and a Ph.D. in Physics from Kansas State University (KSU) in 2012. At KSU he worked in the James R. Macdonald - atomic, molecular and optical physics laboratory and studied coherent control of cold and trapped atomic and molecular systems. After graduation, he was a joint post-doctoral researcher at JILA and the University of Colorado and then a research fellow at the University of Michigan (Ann Arbor). He is a co-inventor of a novel optical method “frequency comb-based multidimensional coherent spectroscopy” that enables the measurement of materials’ optical properties and many-body interactions rapidly and with unprecedented high resolution. His work at Santa Clara University focuses on using the Nobel-Prize-Winning technology of optical frequency combs to study light-matter interactions and ultrafast dynamics in atomic/molecular systems (cold and Doppler broadened) and semiconductor nanostructures.
