I am a PhD candidate in the Department of Computer Science at Columbia University and a member of the Distributed Networks Analysis Research Group.

My advisors are Vishal Misra and Dan Rubenstein.


My research focuses on mobile networked systems operating in delay-tolerant or otherwise challenged environments.

The main theme of my research is the interplay between behavior and communication:

  • How information can be communicated in a robust and reliable way, when node mobility is unpredictable.
  • How distributed communication and behavior can support sophisticated mission goals (e.g., finding trapped victims in a collapsed building).
  • How individual mobility decisions can be constrained or directed to provide for more robust communications guarantees.
I aim to develop algorithms and mobile systems that address these questions, while providing the capacity to adapt, reconfigure, and otherwise dynamically and autonomously respond to a wide range of externalities.
