Prof. Ricardo Miranda Martins

Hello, welcome to my website!

I earned my Bachelor’s degree in Mathematics from the Federal University of Viçosa (UFV), and my Master’s degree and Doctorate in Mathematics from the University of Campinas (Unicamp). Since 2012, I have been a faculty member at Unicamp, where I am currently an Associate Professor (MS5.2).

Some of my current roles include serving as Director of IMECC/Unicamp (2022–2026), among other responsibilities.

On this website, you will find information about my research, the courses I have taught, students I have advised, outreach activities, and some lecture notes.

My e-mail is Ricardo.Miranda [at] unicamp [dot] br.
