CMU undergraduates: please use
All others: please use

Please note: I am generally unable to respond to emails
outside my immediate work environment.  For the many students and researchers interested in my research, please do not take the lack of response from me as an indication that I am not interested.  I surely am but I am much too constrained to respond.
