Gorapada Bera

I am a Research Fellow (postdoc) at University College London, mentored by Aleksander Doan.

Previously, I was a Research Assistant Professor (postdoc) at the Simons Center for Geometry and Physics (2023–2026), mentored by Simon Donaldson. I received my Ph.D. in 2023 from Humboldt-Universität zu Berlin under the supervision of Thomas Walpuski, supported by the Simons Collaboration on Special Holonomy in Geometry, Analysis, and Physics, after being a PhD student under his supervision at Michigan State University.

My research lies in differential geometry and geometric analysis, with a focus on the following areas:

Special holonomy: G2-manifolds and Calabi–Yau 3-folds
Calibrated geometry: associative and coassociative submanifolds, special Lagrangians and holomorphic curves
Gauge theory: generalized Seiberg–Witten monopoles, and instantons on special holonomy manifolds

Preprints:

1. Dirac operators twisted by ramified Euclidean line bundles (joint with Thomas Walpuski)
