Dr. Somjeet Biswas specializes in the mechanics of plastic deformation in ultra-fine and nanocrystalline materials through polycrystalline plasticity simulations with specific applications in aerospace, automobile and biomedical applications.

He has done his PhD in Engineering at IISc Bangalore. He has worked as a researcher in IMDEA Materials, Madrid, Spain and LabEx DAMAS, University of Lorraine, Metz, France. He was awarded the Alexander von Humboldt fellowship to work in Ruhr University, Bochum, Germany in 2013. He has used microstructure and texture engineering techniques like severe plastic deformation, thermo-mechanical processing and recrystallization to modify the morphological characteristics, texture and grain boundary to obtain ultra-fine grain metals and alloys that possess both improved strength and ductility and hold two patents.

His thrust areas of research include the development of advanced lightweight and high strength Mg, Ti, Al alloys and steels for automobiles, aircraft, bio-degradable and permanent bio-implants respectively.
