Departmental homepageDhruv Ranganathan is a Professor of Pure Mathematics, specialising in algebraic geometry. He grew up in India, before moving to the USA in 2008. He received his PhD from Yale University in 2016 and arrived in Cambridge in 2019 after postdoctoral positions at MIT and the Institute for Advanced Study.
Professor Ranganathan lectures in the Faculty of Mathematics in algebra, algebraic geometry, and related areas. In St John's, he supervises courses in Pure Mathematics across the three years of the Tripos.
Professor Ranganathan works in algebraic geometry, and specifically, moduli theory and enumerative geometry. He is interested in the development of a network of ideas known as "tropical geometry", that combines traditional techniques of algebraic geometry with ideas from convex geometry and discrete mathematics.
