About Me:

My primary areas of interest are in Manufacturing and Materials with major emphasis on Shape Memory Alloys, Advanced Manufacturing Processes and Materials Characterization. I have extensively worked on preparation of TiNi based Shape Memory Alloys using Vacuum Arc Melting method and utilized various characterization tools such as XRD, SEM, EDS, DSC, AFM etc. I have operational experience on Vacuum Arc Melting equipment, Wire Electro Discharge Machine, Universal Testing Machine (75kN), Microhardness Tester, Differential Scanning Calorimeter, Atomic Force Microscope and High Temperature Tribometer. I have experience with preparation, characterization and machining of TiNi based Shape Memory Alloys. I have handled Mechanical Engineering Sciences, Manufacturing Technology, Workshop practice and Machine Shop for UG students.

I served as a Junior Research Fellow for a SERB funded research project and worked at NITK Surathkal as Assistant Lecturer for a semester during my Ph.D
