Prospective Students



I am actively seeking highly motivated both undergraduate and graduate students as well as post-docs for my group. If you are interested in any of the projects or have other related interests, please contact me to apply. Please be very specific in your email and do not include attachments that are not in PDF form.

Like many colleagues, every month I receive several inquiries from perspective students, post-docs, and visitors, who wish to join my research group. It is impossible for me to respond to all of these requests, because of their sheer volume. If you try to contact me in this regard, please do not be offended if I do not reply. The admission process for graduate students is handled by the departmental office for graduate studies.
