Photonics Seminar: Vladislav Yakovlev, Texas A&M University

Please join us November 1st, for a one-hour talk from Vladislav Yakovlev, Texas A&M University, titled:

Seeing life in a new light: from simple classical physics to quantum-enhanced imaging

Abstract – The progress of biomedical sciences depends on the availability of advanced instrumentation and imaging tools capable of attaining the state of biological systems in vivo without using exogenous markers. Mechanical forces and local elasticity play a central role in understanding physical interactions in all living systems. We demonstrate a novel way to image microscopic viscoelastic properties of biological systems using Brillouin microspectroscopy [1]. In my talk, I will discuss the ways how an old spectroscopic tool can be used for real time microscopic imaging [2-3] and provide possible solutions to long standing problems in Life Sciences and Medicine [4-6] while advancing instrumentation beyond classical limits [7].

Bio – Dr. Vladislav Yakovlev is working in the interdisciplinary area of optical imaging, spectroscopy and sensing applied to biomedical, environmental and analytical applications. His primary research interest is focused on advanced optical instrumentation for microscopic imaging and remote sensing/imaging. Prior to joining Texas A&M University in 2011, he was a faculty member in Physics Department, University of Wisconsin – Milwaukee (Assistant Professor: 1998 – 2002; Associate Professor: 2002 – 2007, Professor: 2007 – 2011). He was awarded the NSF CAREER Award in 2002. He is also a recipient of the Lamb’s Medal in Laser Physics (2015). He is a Fellow of AIMBE, APS, OSA and SPIE. He is a member of the Editorial Board of Journal of Biomedical Optics and an Associate Editor for Optica. His research was supported by NSF, NIH, AFOSR, ONR, ACS-PRF, Research Corporation and CPRIT.
