Brief Introduction

I am a Golomb Visiting Assistant Professor of Mathematics at Purdue University. My mentor is Donu Arapura. I graduated from The Ohio State University in Spring 2022. My advisor was Herb Clemens.

My research is in algebraic geometry. In particular, I'm interested in Hodge theory and topology of algebraic varieties. Here is my research statement.

Here is my CV.

Seminar at Purdue

I am organizing Purdue Algebraic Geometry seminar with Takumi Murayama and Deepam Patel. This semester we also run a classical paper/preprint seminar.

Upcoming travels/talks

Nov 13-15, Michigan State University

Teaching

Fall 2024: MA 265 Linear Algebra

Mentoring

Summer 2024, organized a problem solving seminar. Here is the problem list.

Summer 2023, mentored two undergraduate students in REU program. It's about lines on cubic surfaces.

Summer 2023, mentored a graduate student in a reading course. The topic is on Riemann Surfaces.

Spring 2022, mentored an undergraduate student exploring a "figure-eight" phenomenon in astronomy. Here is my student's poster.

Spring 2022, mentored an undergraduate student on Stereographic Projects and Mobius Transformations

Notes
