Debabrata Sikdar received his B.E. (Electronics & Instrumentation) and M.Sc. (Physics) from Birla Institute of Technology and Science (BITS), Pilani, India in 2008. From 2008 to 2009 he worked as an Engineer with General Electric in Hyderabad, India. In 2010, he left the industry job for higher studies and he received his M.E. (Communication Engineering) from BITS in 2012. The same year, he was awarded the prestigious Victoria India Doctoral Scholarship to support his doctoral research at Monash University, Victoria, Australia. In 2016, he received his Ph.D. on nanoplasmonics from the Department of Electrical and Computer Systems Engineering at Monash University under the supervision of Professor Malin Premaratne and Professor Wenlong Cheng. Since November 2015, he has been working at Imperial College London as a research associate (postdoctoral fellow) on a multi-disciplinary Engineering and Physical Sciences Research Council (EPSRC)-funded project under the supervision of Professor Alexei Kornyshev and Professor Joshua Edel. His major research interests include nanoplasmonics, optical metamaterials, light-matter interaction at the nano scale, surface plasmon characteristics, optical switching, directional scattering, and nanoparticle-based plasmonic devices.
