Tanveer Karim

PhD Candidate in Cosmology

Harvard University


I am a 5th year PhD student at the Center for Astrophysics | Harvard & Smithsonian. I work under the supervision of Dr. Daniel Eisenstein in the Dark Energy Spectroscopic Instrument (DESI) collaboration, whose goal is to create the most 3D map of the Universe. The broad goals of my dissertation are inferencing cosmological parameters and testing dark energy and modified gravity models using galaxy clustering and cosmic microwave background lensing data. In addition, I also work on building statistical toolsets to identify outliers in astronomical datasets.

Outside of research, I am interested in Diversity, Equity, Inclusion and Belonging (DEIB) efforts in academia, mentoring, and outreach. In my spare time, I enjoy learning (human) languages, reading books and travelling.
