Academic work history

Since June 2006, I have been employed full-time as a researcher and software developer, under Robert van de Geijn, tasked with continuing my work with the Science of High-Performance Computing group (formerly known as the FLAME group) to produce and maintain high-performance linear algebra libraries.

From June 2004 to May 2006, I served as a graduate research assistant on the FLAME working group with my other colleagues, led by Robert van de Geijn. The FLAME project is an effort to explore, refine, and spread the use of a set of verifiable methods which facilitate the derivation and implementation of high-performance algorithms for various linear algebra operations such as those commonly obtained from BLAS and LAPACK.

In November 2003, I was one of a fortunate handful of applicants who was accepted into the Master's program in Computer Sciences at the University of Texas at Austin for spring 2004 admission. Needless to say, I was thrilled to get an opportunity to develop my research career as a computer scientist amongst UT's top-notch graduate students and faculty.

From September 2000 to August 2004, I worked at the Applied Research Laboratories for the Environmental Sciences Laboratory. I was employed as an undergraduate student associate and then a graduate research assistant in the research and implementation of passive sonar processing algorithms, with a focus on adaptive beamforming. Among other duties, I maintained my parallel frequency-domain beamformer, implemented with MPI and formally derived using elements of the FLAME approach (see ARL-TL-EV-03-18 above).

Fun stuff

If you need a good book with a laughing-out-loud sense of wit and humor, try Miss Wyoming by Douglas Coupland, or any of Coupland's novels for that matter. Other recommendations: Generation X, Shampoo Planet, Microserfs, Polaroids from the Dead, Life After God, Girlfriend in a Coma, All Families Are Psychotic, Hey Nostradamus!, Eleanor Rigby and JPod. Visit coupland.com for the official website for Douglas Coupland.

Jenny Holzer is a contemporary American artist who aims to integrate her socially thought-provoking textual art into public spaces. Some of her more famous pieces are titled Truisms (1978-1983), Survival (1983-1985), and Living (1980-1982).

If you enjoy reading the Holzer works cited above, you may enjoy my personal art project, text as art. The idea is similar in concept to the pieces found in Truisms and Survival, though without the public presence that Holzer's work is known for.

Do you have CPU cycles to spare at home or work? Try donating your computing resources to the folding@home project, managed by the PANDE Group of the Chemistry Department at Stanford University. I advocate participation (over other distributed computing projects such as seti@home) because I believe understanding the folding of proteins directly benefits the study of biology and medicine, and thus humankind.
