About Me

I am a 2021 PhD candidate in the Department of Earth, Environment and Planetary Sciences at Rice University, Houston. Currently, I work on early Solar System processes with Dr Rajdeep Dasgupta's group at Rice. In 2019, I received the Future Investigators in NASA Earth and Space Science and Technology (FINESST) grant for two years and the Lodieska Stickbridge Vaughn Fellowship for one year. I have been awarded the Barr Foundation Postdoctoral Fellowship by the Division of Geological and Planetary Sciences, California Institute of Technology where I will start working in January 2022.

I also received the Innovation in Science Pursuit for Inspired Research (INSPIRE), Department of Science and Technology, India in 2007 for a period of five years. As an INSPIRE scholar, I obtained the dual degree of Bachelor of Science and Master of Science in Geology from the Indian Institute of Technology (IIT), Kharagpur in 2012. After graduation, I taught chemistry for engineering and medical school entrance examination for three years in Patiala (Punjab), India.
