Brief Bio

I have been a faculty member at Michigan since 2014. Prior to arriving at Michigan, I served on the faculty at UC Riverside for four years.

My research has received the IRTF’s Applied Networking Research Prize twice and led to award papers at OSDI, NSDI, IMC, and IEEE CNS. I have also received multiple Google Faculty Research awards, a NetApp Faculty Fellowship, a Facebook Faculty Award, and an NSF CAREER award.

I am a recipient of Michigan College of Engineering’s Neil Van Eenam Memorial Undergraduate Teaching Award.

Research Overview

My research is broadly in the area of distributed systems. In particular, I view most of my work as enabling systems support for facilitating the exchange of information within human society. Over the last decade, my group has focused on this topic primarily in two settings:

More recently, I have been investigating new forms of facilitating and benefiting from information exchange in the following settings:

  • Sharing human insights inferred from users’ actions (Federated learning, OSDI 2021)
  • Revisiting use of cloud and edge services in manufacturing (Smart manufacturing, HotMobile 2020)
  • Preserving information on the web across generations

Research Impact

Beyond papers, I strive to ensure that my work has broad real-world impact. To date, some of the ways in which my research has proved useful to users, service providers, and researchers are as follows:

  • Network Error Logging (NSDI 2020) is a proposed W3C standard, which is implemented in the Google Chrome and Microsoft Edge web browsers
  • Vroom (SIGCOMM 2017) is in use on the mobile website of 1-800-Flowers
  • Edge Fabric (SIGCOMM 2017) enabled Facebook to perform capacity- and performance-aware routing of content to its users
  • MyPageKeeper (USENIX Security 2012), an application for detecting social spam and malware on Facebook, was used by over 20,000 users, and its technology was licensed by Cloudflare
  • WhyHigh (IMC 2009) helped reduce latencies to Google from hundreds to tens of milliseconds for millions of users
  • iPlane (OSDI 2006, NSDI 2009) was a system I operated from 2006 to 2016, and its data was used in over a hundred research projects
