Professional Experience

The  following list is sorted in chronological order, starting with the most recent work experience.

• Applied Research in Header Compression for Ad-Hoc Networks
  Institution: Procito Inc.
  Description: Design and implementation of header compression protocols for Ad-Hoc networks. Procito Inc is a private research contractor for the US Department of Defense. This work is part of a research contract with the United States Army to develop an efficient header compression framework for mobile ad-hoc networks in a military environment.

• Terrain Navigation for Virtual Reality Applications
  Institution: Naval Research Laboratory, Department of Defense (Washington, DC)
  Description: Second internship at the Naval Research Laboratory. The work consisted in redesigning a terrain navigation code originally written for a virtual reality prototype (Dragon) for command and control (C2) and battlefield visualization. I ported the navigation code from OpenGL Performer to an API independent navigation module that could be easily plugged into any virtual reality application. The new navigation module is currently being used in a new prototype that integrates Command and Control with a battlefield augmented reality system (BARS) and uses VrJuggler as the virtual reality API. The prototype uses a multi-modal interface that combines voice recognition with hand gestures via a tracking device to produce accurate input commands. During this project I gained considerable experience with six degree of freedom tracking systems and immersive virtual reality hardware.

Some applications were developed to test the performance of noise-reduction algorithms designed by the company. Another application enabled the user to use a laser pointer as a mouse, by tracking the laser through a video camera.  All development was done in Visual C++ using Microsoft Foundation Classes (MFC),  using  speech recognition libraries developed by L&H and Nuance, as well as Microsoft Video for Windows Interface.

• Research in Terrain Rendering
  Institution: Naval Research Laboratory, Department of Defense (Washington, DC)
  Description: I implemented a terrain rendering algorithm called "LOD-sprite" and designed at the Naval Research Lab. The algorithm provides the high rendering speed of other LOD algorithms (level of detail) but obtains a better visual quality by periodically rendering frames at full detail (keyframes) and using them as a texture sprite for the LOD frames. The resulting frame rate was not constant because the keyframes took much longer to render. I fixed this problem by writing a distributed, multithreaded version where the keyframes are renerated ahead of time by a program running on a different host.

Traveling

I have a profound passion for traveling. It is by far my favorite activity during leisure time and holidays. I work hard saving money every year in order to finance my trips. Traveling has been my second university, as it has helped me understand much better the world and its people. I am also an avid outdoorsman and scuba diving fan. Although most of my trips are of ecological, I have done all kinds of traveling. Here is a list of countries and major places that I have been to: Australia and Tasmania, Fiji, Vanuatu, New Zealand, Hawaii, England, France, Belgium, Holland, Germany, Italy, Switzerland, Czech Republic, Austria, Canada, Baja California (Mexico), Cozumel (Mexico), Colombia, United States and Costa Rica.
