Here are my pages on Google Scholar and LinkedIn.

I am also listed in the Mathematics Genealogy Project, and my Erdös Number is four:

As a postdoc, I spent a year abroad at the University of Edinburgh thanks to the NSF's International Research Fellowship Program (IRFP). IRFP no longer exists, but the NSF still provides funding for international postdocs through other programs.

As a graduate student, I spent a winter in Australia and a summer in Singapore thanks to the NSF's East Asia and Pacific Summer Institutes (EAPSI), a great program that still exists.

I have visited 35 countries. I have lived in four of them (USA, UK, Australia, Singapore), to the extent that in each of them I paid rent for a dwelling, bought groceries on a regular basis, and had a workplace.

Photography and Digital Art

In my free time I am a photographer and digital artist. You can browse some samples of my creations.

My camera is a full-frame Canon 6D, and I carry with it an unapologically heavy assortment of lenses.

Judging at Events

I enjoyed serving as a judge for the Pittsburgh Regional FIRST Lego League in 2012 and 2013 and the Intel International Science and Engineering Fair in 2012 and 2015. Talking with young students about their work is a great reminder of the excitement of research, and I can recommend volunteering for either of these programs.

Other Interests

I am particularly fond of the artwork of Edward Hopper. In literature, I've especially enjoyed the works of Sinclair Lewis and Kurt Vonnegut.

I occasionally go geocaching, and I am an amateur radio operator (license KG4LFD, technician class).
