Thank you for being interested in working with me. I enjoy working with students. And yes, I am looking for PhD students starting from Fall 20201 (application due by December 15, 2020). If you are interested, please be in touch with me after you complete your application. Please check out here for general requirement; GRE is NOT required for PhD admission. Having a good math background will be appreciated. Note that I cannot answer questions regarding your chance of being admitted, so please do not ask.
