Sandhya M Rao

Sandhya M Rao is a Research Professor in the Department of Physics & Astronomy at the University of Pittsburgh, affiliated with the Dietrich School of Arts and Sciences. Her research focuses on tracing galaxy evolution through the study of quasar absorption lines, particularly damped Lyman alpha (DLA) systems, which reveal neutral gas distributions critical to star formation processes.

Using instruments like the Hubble Space Telescope, WIYN, and ESO's VLT, she investigates DLA properties across cosmic time. Key projects include surveys of metal abundances in absorption systems and analyses of the circumgalactic medium near galaxies. Rao has contributed to catalogs like the Pittsburgh Sloan Digital Sky Survey Mg II QSO Absorption-line Survey and leveraged SDSS data for large-scale statistical studies.

Her work bridges observational astronomy with cosmological models, emphasizing the role of neutral gas in galaxy formation. While no specific awards are listed, her extensive publications highlight collaborations with institutions globally. She advises students on topics like quasar absorption line analyses and participates in multi-wavelength observational campaigns.

Labs/Teams: Her research involves international telescope networks and computational data analysis teams focused on extragalactic surveys.
