I'm an associate professor in the
Computer Science Department
at
Swarthmore College. I
received my Ph.D. in Computer Science in 1999 from the
University of Wisconsin.
My general research area is parallel and distributed systems, and
my current project,
Nswap, is
a network RAM system for Linux clusters. Nswap
allows individual cluster nodes with over-committed RAM to locate
and use idle RAM of other nodes in the cluster. The goal of the
project is to
speed-up the runtime of cluster applications by avoiding the slow
swapping to disk that normally occurs when a node doesn't
have enough RAM space for the programs it is running.

Research
My general research area is parallel and distributed systems. I'm
currently focusing on system-level support for cluster computing through
my Nswap project, a network swapping (or Network RAM) system.
It is implemented as a Linux kernel module that is designed to run continuously
on a cluster. Nswap transparently provides network swapping to cluster
applications, it is designed to scale to large-sized clusters, and it
automatically adapts to changes in cluster nodes' memory use.

to Ph.D. Programs in Computer Science by Mor Harchol-Balter at CMU. This is
a very good source of information about what getting a Ph.D. is like, how
to apply to gradschool, the importance of grades, GREs, research experience,
and letters of recommendations, how to write a good personal statement,
how to get good letters of recommendation, how to pick schools to which to
apply (and how to pick a school once accepted), and links to fellowships.
