I am a Senior Research Fellow in the Institute for Software Research at Carnegie Mellon University. I have broad research interests at the intersection of programming languages and human-computer interaction. I am particularly interested in better understanding of the factors that influence the usability of reusable software components.

I am fortunate to work with amazing PhD students. I advise Jenna Wise (co-advised by Jonathan Aldrich) and Wode “Nimo” Ni (co-advised by Ken Koedinger). I also collaborate with Katherine Ye.

I direct the Research Experience for Undergraduates in interdisciplinary Software Engineering (REUSE) program with Charlie Garrod and Claire Le Goues. The program provides an opportunity for a diverse cohort of undergraduates from school accross the country to spend the summer working with the world’s leading computer scientists. Students conduct research in a broad range of areas, including: collaboration and teams, computational statistics, computer architecture, diagrams and visualization, data mining and analysis, embedded systems, human-computer interaction, networking, privacy, program synthesis, program repair, programming languages, security, software architecture, societal computing, software requirements, and testing.

I completed my PhD in Software Engineering from Carnegie Mellon in December 2013. My dissertation focused on the usability of software libraries with ordering constraints (API protocols). I was advised by Jonathan Aldrich.

I graduated from Brandeis University in 2004 and worked for almost four years as a software engineer before starting graduate school. I’m married to Kira Sunshine, and we have three children, Akiva, Elisheva, and Tamir.
