I am generally interested in file systems and storage. My research focuses on using modern data structures, in particular write-optimized dictionaries, to improve storage software. I am a member of the BetrFS team. BetrFS is a Linux file system built using Bε-trees, an asymptotically optimal write-optimized dictionary.
As a member of the OSCAR lab at Stony Brook University (now UNC Chapel Hill), I worked for a while on the Graphene library operating system. I later moved to the BetrFS project, and have since focused my work in file systems and storage.
Prior to joining Stony Brook, I explored RNA secondary structure prediction in the Aalberts lab. RNA projects that I have worked on include: RNAbows, a visualization tool for viewing and comparing RNA secondary structures in thermal equilibrium; Bindigo, a tool to optimally BIND olIGOs to longer RNA targets; and Nestor, an RNA secondary structure prediction utility. Nestor is based on stochastically sampling and clustering individual structures with a new and intuitive distance measure.
