Prospective Ph.D. students

I frequently get email from prospective Ph.D. students asking if I have an opening in my research group. However, individual professors at Cornell do not admit Ph.D. students. Admissions to the Center for Applied Mathematics (CAM), Computer Science (CS), Information Science (IS), and Operations Research (OR) Ph.D. programs at Cornell are handled by an admissions committee, and while I am sometimes asked for my input on particular candidates who are directly in my research area, I do not have any control over which students are admitted.

If a student is admitted into the Ph.D. program in IS, OR or CS, the student then has about a year to take classes and discuss research opportunities with various potential Ph.D. advisors. Students and advisors make a mutual decision to work together. I suggest that students who are interested in working with me take a graduate-level class from me and do very well in it.

Foreign undergraduates looking for an internship

I get quite a bit of email from foreign undergraduates (mostly from India) looking for a summer internship in my research group. I very rarely have research-related work for undergraduates, and have so far always hired Cornell students to do this work. I am unlikely to have suggestions of alternatives for you unless your work is directly in my area of interest.
