Tät Ghosh

Currently I am a visiting researcher in the School of Mathematics at University of Leeds working with Dr Derek Harland. From August 2025 I will join National Center for Theoretical Sciences (NCTS) as a postdoctoral fellow.

I have completed my PhD in the School of Mathematics at University of Leeds, researching Instantons on manifolds of exceptional holonomy, supervised by Dr Derek Harland and Dr Gerasim Kokarev. The title of my PhD thesis is Instantons on Asymptotically Conical Spin(7)-Manifolds.

I have completed M.Sc in Pure Mathematics at University of Calcutta, India. I have done my master's dissertation on the topic Introduction to Seiberg-Witten Gauge Theory on 4-Manifolds. Most of the work on the project was carried out at International Centre for Theoretical Sciences (ICTS-TIFR), Bengaluru, India, as a visiting researcher.

Research interests

Broadly, my research area is Geometry and Mathematical Physics. I am interested in Gauge Theory as well as various other geometric structures arising from Quantum Field Theory, Supergravity and String Theory.

I am currently interested in the study of Instantons on manifolds of exceptional holonomy. My recent focus includes Deformation Theory of Instantons on Asymptotically Conical G2 and Spin(7) manifolds, Instantons on asymptotically locally conical (ALC) manifolds, ’t Hooft-type Solutions in Higher dimensions, Heterotic strings and Strominger system, Hermitian Yang-Mills Connections on Calabi-Yau 4-folds, Deformed Donaldson-Thomas Connections on G2 and Spin(7) manifolds.

I am also interested in Instantons and Monopoles in low dimensions, Topological Solitons (Skyrmions, Vortices, Kinks), Higgs bundles and Hitchin systems, Seiberg–Witten and Generalized Seiberg–Witten Gauge theories, Vafa–Witten and Kapustin–Witten theories, Mirror Symmetry; and want to explore these areas and their interplay more in future.

Here is my CV.
