Dr. Jena joined the Department of Physics as an Assistant Professor on 31st of December, 2013. His research expertise is in the field of nonlinear sum-frequency generation (SFG) vibrational spectroscopy and its application to probe the molecular structure various biomolecules and their interactions with interfacial water molecules at air/water and solid/water interfaces. He received his Ph.D. degree in 2008 from the Indian Institute of Technology, Madras, under the mentorship of Prof. Prem B. Bisht and Prof. S. Kasiviswanathan. During his Ph.D. program, he studied the nonlinear optical properties and relaxation processes of organic molecules by using the laser-induced transient grating technique. He joined Prof. Dennis Hore's group in 2007 as a postdoctoral researcher at the University of Victoria, Canada studied interfacial water structure at solid / water interfaces using SFG vibrational spectroscopy. In 2011, he joined Prof. Sylvie Roke's group at Max-Planck Institute for Intelligent System, Germany and subsequently moved to EPFL, Switzerland worked on SFG scattering spectroscopy to probe formation and characterization of model membrane systems at the water / nanoscopic oil droplet interfaces.
