research interests	My research interests lie in the area of programming languages and managed runtimes. Specifically I am interesting in exploring how the runtime system of managed languages can be exploited to heighten program understanding. My research is currently focused on developing techniques to improve understanding of how programs use the heap and to develop techniques for identifying anomalous heap behavior. I do this by using two synergistic techniques: Dynamic Summary Graphs (DSG), a family of graphs used to compactly summarize heap statistics with very low overhead, and (ii) Dynamic Object Sampling (DOS), a method for selectively tagging some, but not all, objects in the heap with additional data. My advisor is Kathryn McKinley. My infrastructure is the Jikes RVM

research groups	Currently I am part of two different research groups: DaCapo Project focuses on compile-time and run-time techniques to improve the memory system performance of high-level object-oriented programming languages, namely Java. Speedway Group focuses on compiler and programmling language research at the University of Texas at Austin.
older projects	Computational Geometry: I started graduate school working with Nina Amenta. Together we worked on helix identification in protein density maps and 3-dimensional super-resolution (2000-2002) Human Computer Interaction Lab: While working as a faculty research assistant at the University of Maryland College Park, I worked with Ben Bederson re-engineering a Zoomable User Interface (ZUI), a project called Jazz. (1999) Senior Summer Scholars: A Study of Hierarchial Data Structures in the Implementation of an Adaptive Ray Tracer work done under Dr. David Mount (1998)
