I lead the blue Systems Research Group and also direct the PhoneLab. My research interests are in systems and networking, mobile systems, and smartphones. I teach an introduction to computer operating systems, a new freshman course on the internet, and a graduate seminar covering a variety of contemporary topics in mobile systems.

We’re Moving!

I did not receive tenure at UB and am looking for new opportunities. If you are looking for faculty with a strong commitment to both teaching and research, please contact me. I will arrive with multiple grant-supported research projects; several excellent PhD students; two popular, scalable, and effective undergraduate courses; blueprints for an exciting new introductory programming series; a commitment to undergraduate engagement; and an excellent track record of department and community service.

Research and Teaching

This site describes my group’s research projects and teaching activities. Please peruse to find out more.


I am active as a technical program committee member and reviewer for the top conferences and workshops in mobile systems ( MobiSys (2017, 2016, 2014), MobiCom (2017), HotMobile (2016), MobiCASE (2016)) and wireless sensor networks ( SenSys (2016,2013,2012,2011), IPSN (2017,2015), and EWSN (2013)). I also regularly review submissions to journals including ACM Transactions on Transactions on Sensor Networks (TOSN), IEEE/ACM Transactions on Networking (ToN), IEEE Transactions on Mobile Computing (TMC), and IEEE Transactions on Parallel and Distributed Systems (TPDS).

In 2015 I began editing a column for GetMobile Magazine. The column attempts to connect past developments with future trends in mobile systems. If you have any idea for a submission, please get in touch.

At UB I led an overhaul of our undergraduate computer science curriculum. Jesse Hartloff and I also designed a new series of introductory courses.

I am also involved in efforts to try and improve diversity within computer science. With help from Natasha Sanford and later Gela Malek Pour, in in 2014 I helped start a UB chapter of the Scientista Foundation which promotes female participation in STEM. Our local chapter is focused on women in computer science and, with the help of generous support from Bloomberg, has held a series of successful events on campus bringing attention to this important issue. I also organized donations to create a diversity in computer science mural, this iconic photo of Grace Hopper now adorns the wall outside our lab.


My interest in computer science was kindled when I took an introductory course on operating systems from Margo Seltzer in 2000. As a graduate student I worked on sensor networks and dreamed that motes would truly become ubiquitous. While I worked on sensor networks that dream came true, but while the sensor network community mired itself in the problems created by ad-hoc routing, smartphones realized the vision of a planetary-scale distributed system. I began working on these transformative devices after completing my dissertation and have not looked back since.

I joined the University at Buffalo in 2011 and established blue in the same year. I enjoy faculty life and the challenge of meeting my commitments to teaching, research, and service. Maintaining the balance is frustrating at times, but ultimately extremely fulfilling. The chance to work closely with my students and help them learn is my greatest joy, whether that occurs in the lab, in the classroom, or beyond. I have been blessed with a great group of students—hard-working, talented, and a pleasure to be around.

I received my A.B. in Physics in 2003 and a Ph.D. in Computer Science in 2010, both from Harvard. As a graduate student I studied with Matt Welsh and worked on using wireless sensor networks to study active volcanos. We performed several deployments on Ecuadorean volcanos including Tungurahua (2004, 2007) and Reventador (2004). Our field experiences generated several projects addressing challenges typical to using resource-constrained devices for scientific purposes. Lance used policy modules to enable-utility driven bulk data collection, and IDEA (Integrated Distributed Energy Awareness) harnessed distributed energy to maximize global network objectives. I also spent a brief stint at MIT as a postdoctoral associate funded by Hari Balakrishnan.

My wife and I live in a small house in Buffalo’s up-and-coming West Side, several blocks west of the intersection of Grant and Lafayette and a few blocks east of Niagara Street. Our small home is perpetually under construction but has provided opportunities for me to learn how to install hardwood flooring and baseboards, do basic electrical wiring, and now hang doors. We live with an adorable pair of animals: a cat named Xyz (pronounced "Ziz") and a dog named Chuchu. Before he was fired by university administrators, Chuchu had a steady job as our resident therapy dog and lunch stealer. I enjoy cooking and traveling and am a 3+ season bike commuter.
