About me

I am an assistant professor at CSE, IIT Delhi. I am interested in ML systems and distributed systems.

Prior to joining IIT Delhi, I spent an year at Instabase and another couple years as the CTO of Mobile Enerlytics, a startup I co-founded. I received my Ph.D. from Purdue University where I worked closely with professors Y. Charlie Hu and Samuel Midkiff. I earned my undergraduate degree from IIT Kanpur.

Impact

• We found hundreds of new energy bugs across all software layers including popular apps like Facebook and Netflix, Android framework, Android kernel, and the device drivers. We applied several patches to the Linux kernel to fix the kernel bugs.

• One class of energy bugs identified by us, called no-sleep bugs, is being checked for by Wakelock and WakelockTimeout lint checks in Android Studio, since 2012, every time any Android app is built.

• We launched an “eStar battery saver app” which was downloaded by over 100k Android users. The app was widely discussed in media (1, 2).

• Our Hush system received over 50 forks, 150 stars on Github, and global media coverage (1, 2, 3). Ideas similar to the ones in Hush were released as “app-standby” and “Doze” battery-saving features in Android Marshmallow.

• Our measurement study to understand daily battery drain breakdown and our work on differential energy profiling were also widely covered in media (1, 2).
