Curriculum Vitae



I am a graduate student at The Ohio State University since 2013, working under the supervision of Roman Holowinsky. My current research lies in Analytic Number Theory, with a focus on the study of L-functions and the subconvex bound problem. I am currently on the job market looking for teaching and research positions.
