Girish Kulkarni

I am a faculty member in the Department of Theoretical Physics of the Tata Institute of Fundamental Research (TIFR) in Mumbai, India, and the head of a partner group of the Max Planck Institute of Astronomy (MPIA) of Heidelberg, Germany.

My research is in the area of astrophysics and cosmology. I study the properties of the universe in the first billion years of its existence. Some of the questions I try to answer are how did the temperature of the universe evolve throughout the cosmic history; when and how did the first stars, black holes, and galaxies form; and what is the nature of dark matter. In my work, I collaborate closely with experimentalists as part of programmes such as SKA, REACH and XQR-30 that exploit some of the biggest current and upcoming astronomical facilities across the world.

Contact me if you are interested in doing a departmental project or a PhD thesis with me. Also get in touch if you are looking for a postdoc position to work with me, or if you would like to visit TIFR. I am currently not available to work with students for masters or summer projects.
