Many foreign students and faculty email me indicating that they want to study at UPenn under my supervision. While I am sympathetic to such requests, given the volume of such requests, I cannot respond to or accept any such requests.
If you are a graduate student who would like to study at Penn, then please apply for admission to our graduate program, and indicate special student status on the webform.
If you are a faculty member, I can only respond to a request supported by a recommendation from someone I know.
