I am an associate professor (w/out indefinite tenure) in the Computer Science Department
and (by courtesy) the Electrical and Computer Engineering Department
at Carnegie Mellon University, leading the CORGi research group.
I am also co-founder and Chief Scientist at Efficient Computer Company, where I am currently on leave. We're hiring!
I am interested in computer systems, computer architecture, and performance modeling.
Please see the CORGi group web page for the
projects I am currently working on,

NSF Panel Member in 2019 and 2018.
My PhD (2012-2015) was advised by Daniel Sanchez
at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL).
I stayed for a one-year postdoc with Daniel (2015-2016).
My PhD thesis, Design and Analysis of Spatially-Partitioned Shared Caches,
received the 2015 Sprowls Doctoral Thesis Prize for the "best PhD thesis in computer science at MIT".
This work introduced the software-defined cache, a new abstraction to manage data placement in large multicores
to dramatically reduce data movement.
Before that, I worked in Anant Agarwal's group
on fos, a distributed operating system for multicore and clouds (2008-2011).
After Anant joined edX full-time,
I briefly worked with Frans Kaashoek
and Nickolai Zeldovich
in the PDOS group (2011-2012).
A long time ago, I also worked on Graphite, a distributed multicore simulator.
My other interests include math and
I received my masters degree in 2010 from MIT.
My thesis, "Distributed Naming in a Factored Operating System",
won the William A. Martin Memorial Thesis Award for an outstanding Master's thesis.
I got my Bachelors of Science from the University of California, Los Angeles.
I graduated summa cum laude in Computer Science and Mathematics of Computation
and was honored as the Bachelor of the Year (2008) in Computer Science.
