Applying to OSU: You can find more information about our PhD program here, and instructions on applying here. I have funding to support RA positions and I am typically looking to recruit one or two new PhD students per year. Feel free to mention my name in your research statement if you are interested in working with me, and also send an email to make sure that your application doesn't get lost in the pile. I get many of these emails, so unfortunately I don't have time to reply to all of them, but that doesn't mean I haven't read your note!
Computing Resources: My group has dedicated high-memory, GPU and storage servers. In addition we have access to the Ohio Supercomputer Center which houses 160 Nvidia P100 GPUs.
Life in Columbus: Columbus is the state capitol and Ohio's second largest metropolitan area. There are typically many events happening here every weekend, to see what's going on this weekend, check this link. Columbus is an affordable city to live in which is nice for those who are living on a PhD stipend.
For Students who are Already Admitted to OSU: Feel free to send me an email with your C.V. or resume and optionally, a brief description of what areas you think we might be mutually interested in working on. I like to recruit students who have a strong programming / math background and are also highly self-motivated; taking a course with me (and doing well) is a good place to start. You can learn more about my group's research on my publications page.
