About Me

I am in my eighth year as a teaching-track faculty member at the University of Pennsylvania, and am director of the Masters of Computer & Information Technology program.

Although my primary focus is on teaching, I'm also interested in online education, student contributions to open source software projects, and how these affect diversity and inclusion within CS.

Prior to joining Penn, I completed a PhD in Computer Science at Columbia University, where my research focused on software testing. Before that, I worked as a professional software developer in Boston, San Francisco, and London after earning a BS in Computer Engineering from Boston University.

Somewhere along the way, I also spent two years teaching English in Seoul, but that's not really part of the narrative hahaha...

News

If I ever got around to using Twitter, these are the things I'd mention (#humblebrag):

My student Judy Weng and I presented a paper on open source software, diversity, and inclusion at the RESPECT conference in Baltimore in February 2018 (Judy wrote a post in the Penn Engineering blog about this work following our participation in the ACM Richard Tapia Celebration of Diversity in Computing).

Dr. Jennifer Akullian of the Growth Coaching Institute and I led a successful Birds of a Feather on mental health issues in the field of computing at the SIGCSE conference in Baltimore in February 2018.

In Summer 2017, my first two online courses were launched on edX as part of Penn Engineering's "CS Essentials for Software Development" professional certificate series.

In May 2017, my student Sydney Morton posted an article in the Penn Engineering blog about her experiences in software engineering education and her contributions to our SIGCSE paper earlier that year.

Research, Publications, and Presentations

My current research is focused on computer science education, particulary in how to create "real-world" experiences for software engineering students, including having students contribute to open source software projects. I am also interested in the effect this has on diversity & inclusion, as well as student mental health. Here are some recent publications and presentations in those areas:
