Dr. Dheeraj Kumar Singh received his Ph.D. degree in Physics from Banaras Hindu University (BHU), Varanasi, India, in 2010. Dr. Singh was subsequently a CSIR-Nehru postdoc at NCL Pune, NRF postdoc in Seoul, South Korea, and finally was granted the renowned Alexander-von-Humboldt (AvH) postdoctoral fellowship for research in Germany. He was also awarded the prestigious international award of a JSPS fellowship, Japan, Dr. DS Kothari postdoctoral fellowship, CSIR-SRF, UGC-Meritorious fellowship (RFSMS), etc.

Currently, Dr. Singh is working as Associate Professor at School of Nano Sciences, Central University of Gujarat. His research group is mainly focused on Nanomaterials, frequency- and time-domain spectroscopic techniques, their developments and applications on ionic liquids, biomolecules, functionalized nanomaterials, molecular interactions, materials for renewable-energy production, etc. Dr. Ashish Kumar Mishra obtained his Ph.D. from the Indian Institute of Technology, Madras, in 2011. He worked as Postdoctoral Research Associate at Rensselaer Polytechnic Institute, USA (Jan 2012-Dec 2014), and as INSPIRE Faculty at IISER Bhopal, India (Feb 2015-Sep 2016).

Currently, Dr. Mishra is working as Associate Professor in the School of Materials Science and Technology, IIT BHU. His research focus covers the fields of thermal transport study, optoelectronics, and energy applications of 2D materials like graphene, MoS2, MoSe2, etc. Prof. Arnulf Materny received his Ph.D. in 1992 with distinction under the supervision of pioneer Raman spectroscopist Prof. Wolfgang Kiefer at the University of Würzburg, Germany.

Further, he was Postdoc at Caltech, Pasadena, USA. There, he started to work in the field of "femtosecond spectroscopy" in the group of Nobel Laureate Prof. Ahmed H. Zewail. Currently, Prof. Materny is serving as Full Professor of Chemical Physics at Constructor University Bremen, Germany. His research interests cover the development and application of frequency- and time-domain spectroscopic techniques to various molecules and materials with a special focus on linear and nonlinear Raman spectroscopy.
