Reseach

I am most interested in Number Theory and Arithmetic Geometry. Currently I am focusing on automorphic forms, theta correspondence, L-functions, endoscopy, periods and Abelian varieties.

Potential Student Projects

Some projects of varying levels (unsorted). Please contact me if you are interested in learning or shaping the projects with me.

• Understand Class Field Theory. This is the GL₁-case of Langlands Correspondence.
• Modular forms, automorphic forms and automorphic representations. Potentially also spectral theory, trace formulae.
• Study and compare many constructions of L-functions.
• Theta correspondence and endoscopic correspondence. Certain useful constructions from the descent method. Langlands parameters and Arthur parameters.
• Study elliptic curves with complex multiplication. This is closely related to the Class Field Theory project.
• Understand modular curves i.e., moduli spaces of elliptic curves.
• Hilbert modular surfaces (which are moduli spaces of certain Abelian varieties). One may need to use software such as SageMath to do some numerical computation.
