I am a Distinguished Professor and Associate Dean in the College of Information and Computer Sciences at UMass Amherst. My research interests lie broadly in distributed systems and networking. I head the Laboratory for Advanced Systems Software here at UMass where we focus on building systems and understand them through modeling, analysis and experimentation. I direct the recently established Center for Smart and Connected Society (CS2) and previously directed the Center for Personalized Health Monitoring (CPHM), at UMass.
I am an experimental Computer Scientist with a focus on distributed systems and networking. My current research projects focus on cloud computing, green computing, and energy informatics. I also maintain broad interests in operating systems and virtualization, storage and data management, IoT and sensor networks, mobile and multimedia computing, and Internet-scale systems.

I am on a Conti sabbatical for the 2021 year and will not teach this Fall. I will resume teaching Distributed and Operating Systems (Compsci 677) in Spring 2022.
I have become more selective in my external professional service due to my internal role as Associate Dean.
I recently co-founded and serve as the Chair of the ACM Special Interest Group on Energy (SIGEnergy), a professional group that focuses on energy informatics and computational sustainability.
I recently served as the General Co-chair of ACM/IEEE IoTDI 2020 and program co-chair of ACM/IEEE IoTDI 2019. Previously, I have served as Program Chair or General Chair for sixteen conferences and workshops. Here is a list of conferences I have chaired.
I have served or am serving on the editorial boards of ACM Transactions on IOT (TIOT), ACM Modeling and Performance Evaluation of Computing Systems (TOMPECS), ACM Transactions on the Web (TWEB), Springer Multimedia Systems, Sustainable Energy, Grids and Networks, PeerJ Computer Science. I have previously served on the Steering Committee of ACM e-Energy, ACM BuildSys and IEEE Trans. on Mobile Computing.
