Keshav Jha

Postdoctoral Scholar

My name is Keshav Jha, and I am from India. I received Marie Skłodowska-Curie Fellowship to purse Ph.D. at Leibniz-IPHT in Jena, Germany, where I worked on the time-resolved spectroscopy of Ruthenium and BODIPY molecules in solution and bio-membranes to evaluate triplet state properties in the bio-environment. The triplet state dynamics play a crucial role in photodynamic therapy (PDT), triplet-triplet annihilation upconversion (TTAUC), and thermally activated delayed fluorescence (TADF) applications. My doctoral thesis discusses two major findings: first, rotational dynamics of a BODIPY-cholesterol molecule along its three-dimensional axes at picosecond timescale; second, the localization of the molecules in the biomembrane can result in a highly effective triplet-triplet energy transfer process despite the increased viscosity of the medium.    

My research interest is to investigate physio-chemical processes in biological systems using optical spectroscopy and microscopy, such as conformational dynamics of proteins. In pursuit of this goal, I joined the group of Dr. Hendrik Utzat for postdoctoral research; here, I am developing a novel spectroscopy technique to map the conformational dynamics of proteins. In addition to my academic endeavors, I am a trained yoga teacher and love to do yoga with my friends and colleagues.
