Rohini Ramadas

I am a Tamarkin Assistant Professor and NSF postdoc at Brown University. My research is in algebraic geometry and complex dynamics. More specifically, I’m interested in moduli spaces of stable curves, stable maps, and admissible covers; also in Berkovich spaces, tropical geometry, and dynamics on the Riemann sphere.

Here is my CV.

My office is: 219 Kassar House, 151 Thayer Street, Providence RI 02912


During the academic year 2017-2018 I was an NSF postdoctoral fellow at Harvard University. I received a Ph.D. in Mathematics in 2017 from the University of Michigan, advised by David Speyer and Sarah Koch. In 2011, I received a Master’s degree in Biology from the National Centre of Biological Science in Bangalore, where I spent four years in a Ph.D. program, advised by Mukund Thattai. During this period, I took math classes at the Indian Institute of Science, and also spent Fall 2009 at the Budapest Semesters in Mathematics. My undergraduate degree is in Life Sciences and Biochemistry, from St. Xavier’s College, Mumbai.

I endorse Federico Ardila's axioms:

Axiom 1. Mathematical talent is distributed equally among different groups, irrespective of geographic, demographic, and economic boundaries.

Axiom 2. Everyone can have joyful, meaningful, and empowering mathematical experiences.

Axiom 3. Mathematics is a powerful, malleable tool that can be shaped and used differently by various communities to serve their needs.

Axiom 4. Every student deserves to be treated with dignity and respect.
