Madeleine Udell

  • Cornell PhD students: I will be taking on a few PhD students this year. Send me an email or drop by my office if you're interested in working with me. Potential projects include

    • low rank and structured optimization,

    • missing value imputation,

    • automated machine learning,

    • fair and interpretable machine learning,

    • if you have your own project in mind, come tell me about it!

  • Cornell masters and undergraduate students: Get in touch if you've got a strong computational background, have taken or are taking one of my classes, are willing to work on research for at least ten hours a week for at least a year, and are interested in one of the problems above; and mention you've read this.

  • Students at other universities: If you'd like to work with me, please apply to a PhD program at Cornell! I advise students in many different PhD programs: ORIE, Stats, CS, ECE, and CAM. Take a look at the core course requirements and faculty research profiles for each and see which one fits your interests best. I'm not able to reply individually to emails from prospective students, but I'm glad to chat once you're accepted.
