Puragra Guhathakurta

Puragra Guhathakurta is a Professor of Astronomy and Astrophysics at the University of California Santa Cruz, where he has held a continuous faculty position since November 1994. His research focuses on galactic structure and evolution through detailed studies of stellar populations in the Milky Way, Andromeda (M31), and Triangulum (M33) galaxies using multi-wavelength surveys.

His educational background includes:

• PhD and MS in Astrophysical Sciences, Princeton University (1985-1989)
• Physics, University of Calcutta, Science College, Rajabazar (1984-1985)
• BSc in Physics, Saint Xavier's College, Kolkata (1980-1983)
• La Martiniere for Boys, Kolkata (1970-1980)

GuhaThakurta's primary research interests encompass:

• Galactic and Extragalactic Astronomy
• Stellar Populations and Chemical Abundances
• Galactic Structure and Kinematics
• Chemical Evolution of Galaxies
• Stellar Halos and Tidal Streams
• Dwarf Galaxy Dynamics

Analysis of his 15 most recent publications (2023-2025) reveals a consistent focus on chemical abundances and kinematics in nearby galaxies. His work integrates Hubble Space Telescope imaging, ground-based spectroscopy, and Gaia astrometry to investigate weak CN absorption features in evolved stars, stellar halo structures, and the evolutionary histories of dwarf galaxies. A significant theme involves using resolved stellar populations to constrain galaxy formation models in the local universe.

His major professional recognitions include:

• Hubble Fellowship (Princeton University, 1992-1994)
• Three-year Membership at the Institute for Advanced Study (1989-1992)

While specific details of his advising and grant history are not documented in the source material, his extensive publication record demonstrates sustained research leadership. He is a principal investigator or key collaborator in major observational programs including SPLASH, PHATTER, HALO7D, and TREX, which have produced foundational datasets for studies of M31 and M33.
