Biography

Dr. Satyendra Thoudam is an Astrophysicist with a long experience in theory and experiment related to cosmic rays and high-energy gamma rays. His primary research is directed towards understanding the origin and propagation of cosmic rays in the Universe. He has worked with different types of Astroparticle Physics experiments such as the TACTIC and MACE gamma-ray Cherenkov telescopes in India, the LORA air shower array and the LOFAR radio telescope in the Netherlands. Currently, he is mainly involved in the radio detection of cosmic rays with LOFAR and the development of the proposed ALTO particle detector array for gamma-ray astronomy in the Southern Hemisphere. Besides the experimental activities, he has also worked extensively in theoretical studies related to the propagation of cosmic rays and high-energy diffuse gamma-ray emission in the Galaxy, and studied various new problems in high-energy astrophysics revealed by new-generation experiments.
