Mr. Rabin Mahat
Rabin Mahat is a result-oriented and multifaceted doctoral student in Experimental Condensed Matter Physics at The University of Alabama, USA. He is currently working under the guidance of Dr. Patrick LeClair, and Dr. Arunava Gupta. He received M.Sc. in Physics in 2013 from Tribhuvan University, Nepal. He also received his second M.Sc. in experimental Condensed Matter Physics from the University of Alabama in 2019. Rabin's main research is focused on the discovery of novel half-metallic Heusler compounds for potential spintronics device applications. He excels academic and professional expertise in process engineering, research procedures and material science.
