Dr. Smijesh N. joined the School of Pure & Applied Physics as Assistant Professor in October 2019. He completed his doctoral studies from the Department of Physics, National Institute of Technology Calicut (NITC), Kerala India and has postdoctoral experience in international laboratories for around 5 years. He worked as a postdoctoral fellow at the Raman Research Institute and joined the Australian Attosecond Science Facility (AASF), Griffith University, Australia as a postdoctoral researcher. Further, he worked at the Relativistic Attosecond Science Laboratory (REAL), Ume ̊a University, Ume ̊a, Sweden as a postdoc before joining the Mahatma Gandhi University. During this period, he has gained experience in the field of intense light-matter interaction (Ultrafast and Attosecond Physics), which has a lot of applications in various fields ranging from physics to medicine. Currently, he is an Adjunct Research Fellow at the Centre for Quantum Dynamics, Griffith University, Australia.
