Tej Chand
Tej Bahadur Chand was born in Dadeldhura, Nepal. He received his PhD in High Energy Astrophysics from the Centre for Space Research (CSR) at North-West University, South Africa, under the supervision of Prof. Markus Böttcher.

He is currently a postdoctoral researcher in the Astrophysical Plasma Group at Instituto Superior Técnico (IST), Lisbon, led by Prof. Frederico Fiuza. His research focuses on particle dynamics in relativistic jets, employing PiC techniques to study the interplay of multiple mechanisms, such as collisionless shocks and plasma instabilities, in accelerating plasma particles to relativistic energies. Apart from kinetic simulations, his research interests include large-scale fluid simulations of relativistic jet plasmas to investigate the large-scale behavior of plasma in jets.
