Biography:

Preeti Kharb obtained her B.Sc. from Miranda House College, Delhi University, in 1994, her M.Sc. from Delhi University in 1996, her Pre-Ph.D. from Jawahar Lal University (JNU) in 1997, and her Ph.D. from the Indian Institute of Astrophysics and Bangalore University in 2005. After post-doctoral positions at the Rochester Institute of Technology (RIT) and Purdue University in the USA, she joined the faculty of the Indian Institute of Astrophysics, Bangalore, as a Reader, in 2012. She moved to NCRA in September 2016, and is currently a Reader-F.

Research description:

My research is primarily related to the phenomenology of Active Galactic Nuclei (AGNs). In particular, I am interested in probing jet physics in AGNs. Some of the fundamental questions that I have attempted to address in my research are - what factors are responsible for the production and launching of AGN jets, their collimation and their propagation through the interstellar and intergalactic medium (for instance, the role played by the environment on jet propagation). I have attempted to address these questions with a multi-scale, multi-wavelength observational approach, using ground-based telescopes like the Very Large Array, the Very Long Baseline Array, and the Giant Metrewave Radio Telescope, and space-based telescopes like the Hubble Space Telescope and the Chandra X-ray Observatory.
