Bio

Dr. Abhilash Ravikumar currently serves as Assistant Professor (Sr.Gr.) at the Department of Electronics and Communication Engineering, School of Engineering, Amrita Vishwa Vidyapeetham, Bengaluru Campus.

He completed his bachelors in Electronics and Communication Engineering from Amrita School of Engineering, Bangalore (2011). Later his interest towards fundamental physics led him to write GATE in Physics and did his M.Tech from National Institute of Technology-Surathkal and Indian Institute of Science, Bangalore in Materials Science (2014). Here he mainly worked on Density Functional Theory models to understand the adsorption of graphene on silicon(111). Later he joined as a Marie Curie doctoral Fellow under Prof. Brivio at University of MilanoBicocca where he mainly worked his spin-dependent, conductive properties of core excited and functionalized graphene. He continued his post-doctoral research at University of Milano-Bicocca in the same group and worked on Green’s function techniques to study quantum transport in 2-D heterostructure interfaces.
