Rohini Ramadas

I am a Tamarkin Assistant Professor of Mathematics and NSF postdoctoral fellow 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; in Berkovich spaces and tropical geometry, and in the dynamics of rational maps on the Riemann sphere as well as in higher dimensions. I've studied dynamical systems on moduli spaces as well as moduli spaces of dynamical systems.

During the academic year 2020-2021, I will not be teaching; I'll be supported by the NSF. This fall, Fall 2020, I'll apply for tenure-track positions. Here is my CV.

Recent and upcoming (online) talks

April 29 2020 at 1PM EDT: ADIOS (Arithmetic Dynamics International Online Seminar).


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.
