I am Dr. Yogesh Chandra Joshi,
scientist at Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, India

About Me

I have been working at ARIES since 1997, first as a Research Scholar, then a Research Associate and now as a Scientist. My primary research focus is on Galactic astronomy and nearby galaxies of the Local Group. My scientific interests lie in the areas of optical astronomy involving time domain analysis particularly extrasolar planets, variable stars, and star clusters. I am also very interested in understanding Galactic archaeology. Recently, my research has also focussed on understanding star formation activities in some of the nearby galaxies.

I completed my PhD in the field of gravitational lensing in 2004 where I searched microlensing events towards M31 galaxy using pixel analysis technique. As a postdoctoral fellow at TIFR, Mumbai during 2004-2006, I focussed on understanding the Galactic archaeology using open star clusters located in the Milky Way. I carried out my second postdoctoral research in the field of extrasolar planets (exoplanets) in the SuperWASP group at the Queen's University, Belfast in UK where I had co-authored several papers on discovery of extrasolar planets around nearby bright stars. Since 2009, I have been a permanent faculty at ARIES, Nainital and currently hold a position of Scientist 'F' (Professor). I have published 66 peer-reviewed papers including 21 as a lead author and have more than 3700 citations with H-Index 33. I have also published 26 short papers at national/international conferences. The highlight of my scientific work includes "Detection of first Microlensing event from India", led the discovery paper on "Exoplanet WASP-14b", and "Determination of Sun's displacement from the Galactic Plane".

Apart from core research acitivities, I am also deeply involved in the scientific communication among astronomers and science popularization among general public. I engage bright young students to become familarize with the advances in the field of astronomy and astrophysics and learn new techniques to bring scientific outcome through short-term research projects and online engagements.
