Web-friendly course & internship work, in reverse chronological order:
-
Mojitos: A Distributed Steganographic File System
Term project for UW's OS quals course, cse551, taught by Steve Gribble & Ed Lazowska in spring 2004.
-
Robot Localization Using Wireless Ethernet Signal Strength (.ppt)
Term project for UW's networking quals course, cse561, taught by David Wetherall in autumn 2003.
- Tools for Energy Minimization Problems in Vision (.ps)
Written report on my work in the summer of 2003 at NASA Ames. I worked in the K9 Mars rover lab under the guidance of Matt Deans and Larry Edwards.
- Mini Presentation on Mobile Robot Localization (.ppt)
Miniature 10-minute presentation on mobile robotics given at the end-quarter "symposium" for cs327, Stanford's advanced robotics course. Taught by Oussama Khatib in spring 2003.
- Formalisation de la Chirurgie (Surgical Formalization) (.ppt)
Informal presentation on my work in the summer of 2002 at INRIA Sophia-Antipolis (France). I worked on the ChIR surgical robotics team under the guidance of Eve Coste-Maniere. Presentation is in French.
- Tree-Based Motion Planning (.doc)
Term project for Stanford's motion planning course, cs326. Taught by Jean-Claude Latombe in spring 2002. This one is very project-specific and may be difficult to understand without knowledge of the assignment and project.
