Rate My Professor Dhruv Ranganathan

Professor Ranganathan's research interests lie in algebraic geometry, particularly enumerative geometry and Gromov-Witten theory, moduli spaces, tropical geometry, logarithmic structures, and the study of degenerations and classical geometry of curves. He delivers lectures in algebra, algebraic geometry, and related areas within the Faculty of Mathematics and supervises Pure Mathematics courses across all three years of the Tripos at St John's College. As Director of the Faculty's Summer Research in Mathematics (SRIM) and Cambridge Mathematics Placements (CMP) programmes, he has led their expansion to engage up to 90 undergraduate students annually, fostering research experiences, public presentations, collaborative projects, and applications to real-world problems. His key publications include "Moduli of stable maps in genus one and logarithmic geometry, I" with Keli Santos-Parker and Jonathan Wise (Geometry & Topology, 2019), "Brill-Noether theory for curves of a fixed gonality" with David Jensen (Forum of Mathematics, Pi, 2021), "Logarithmic Gromov–Witten theory and double ramification cycles" with Ajith Urundolil Kumaran (Journal für die reine und angewandte Mathematik, 2024), and "Logarithmic Donaldson–Thomas theory" with Davesh Maulik (Forum of Mathematics, Pi, 2024). Ranganathan has been awarded the Faculty Lecturing Prize in 2025 and the Pilkington Prize in 2026 for his outstanding teaching contributions.
