Dr. Anish Roshi graduated with an engineering degree in electronics and communications from the University of Kerala. In 1989, he joined the Tata Institute of Fundamental Research (TIFR), National Center for Radio Astrophysics, Pune as a Research Associate/Scientific Officer. At TIFR, he completed his Ph.D (Physics) specializing in Radio Astronomy (1999) and was appointed as a member of the faculty.
He was a Jansky postdoctoral fellow at the National Radio Astronomy Observatory (NRAO), USA between 2000 and 2002. On completion of the post doctoral fellowship, Dr Roshi joined the Raman Research Institute (RRI), Bangalore. While at RRI his biggest contribution was in leading a team of engineers in successfully designing and building a digital receiver for the Murchison Widefield Array, located at Western Australia.
In 2010, Dr. Roshi moved to the National Radio Astronomy Observatory (NRAO), USA. At NRAO, he was the System Architect and Project Scientist for the Versatile Astronomical Spectrometer that was built for the Green Bank Telescope (GBT). He was also the System Architect for the Phased Array Feed (PAF) project. PAFs are specialized feed to increase the field of view of a radio telescope.
Since 2018, he is a Senior Observatory Scientist and Head of Radio Astronomy at the Arecibo Observatory, and a Scientist at the FSI. Dr. Roshi’s research interests in Astronomy are the study of galactic Interstellar Medium (ISM), molecular cloud formation and massive star formation.
