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 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).

Let's play the penguin
game!
Here's how it works: swing the baseball bat at the right time to send

start out by watching Klaus learn how to not operate
a forklift. (Thomsen)
- It's wise to learn from others' mistakes. Checkout this essay on El Niño
(that's Spanish for "the Niño") and this short biography on Walt Whitman.
(Malik)
- For those moments when you can't find any bubble
wrap, but
wish you could. (Dad)
- For never was a story of more comedy than this parody of
Juliet and her
Romeo, cast in the modern language of "l33t" speak. (Driver)
- Haven't you heard? Poetry
is a man's gift! Well, at least according to a fellow by the name of
Tal that lived down the hall from Mark at the Castilian during our
first year at UT. Yes, this was actually turned in to a college-level
English class. (Kurtz)
- Check out the badgers
(linked above). Fan of Harry Potter? If so, you'll love this spoof! (Starr)

stand-up comedy. Here
he talks about Creation, and here, nursery
rhymes. (Gross)
- The
Ladder Theory
attempts to explain sexual attraction between men and
women. Most of us have probably observed
many of these behaviors anecdotally in isolated settings. (Gross)

matter. Other recommendations:

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 with much less emphasis placed on embedding
the art in public.
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.
