Key Strengths:
§
Mathematics.
Algorithm Analysis is a tough course in CS Department of WPI. I was the
top 1 student out of 30 classmates. Digital Signal Processing is a course
provided by ECE Department of WPI. I was the only student from CS
department who survived this course in that semester. My research direction
required a strong background of computational geometry, matrix computation and
statistics. I can handle them quite well and even designed my own algorithm to
solve some complex problems.
§
Quick
Learning. My
master research topic was a computer graphics related issue. However, my first
job was to write a hardware driver in VIA inc. It took me two weeks to learn the hardware
architecture. Then I coded for IDE interface and IO control hub. To support VGA
cards, I spent another two weeks on learning the AT&T assembly language
and the MMX instructions. Finally, I took charge of software solutions of
the video related algorithms, such as interlacing, image resizing and edge
detection.
§
Debugging.
Based on the
standard IDE specification, I caught two hardware bugs in INTEL 845 GV
motherboard: 64k boundary problem and self-increment of the physical base
address register. I also found some fatal hardware bugs in TV cards made by VIA
Company. As a research assistant in WPI, I was charge of the software developed
by my research group. Therefore, I tested and debugged different modules in
different systems.
