(I go by Tia, she/her)

I'm a professor in the Computer Science Department at Swarthmore College. I received my Ph.D. in Computer Science in 1999 from the University of Wisconsin where I was advised by Bart Miller. My general research area is parallel and distributed systems.

My general research area is parallel and distributed systems. My main projects, Nswap and Nswap2L, implement fast backing storage systems for cluster computers. 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. Nswap2L implements a virtualization layer on top of a heterogeneous collection of cluster storage devices including Nswap Network RAM, Flash SSD, disk and other cluster-wide backing store. It is added as a single block device to individual cluster nodes that transparently manages block placement on the set of underlying heterogeneous storage devices.
