**RAYTHEON** **- Space and Airborne Systems** 2003-2006

Designs, develops, manufactures, integrates, supports, and provides a range of technologically advanced products and services for domestic and international governments and commercial customers

**Systems Engineer, **Goleta, CA** **(2005-2006)

Performed data analysis on the visible-infrared imaging radiometer suite (VIIRS), a weather satellite scheduled for launch in 2008.

Analyzed the band-to-band registration of the 22 imaging bands which are responsive to various wavelengths of light from visible to infrared. Used Matlab to make scatterplots of registration of different band combinations.

- Performed analysis on the pointing behavior of VIIRS by determining in what direction the satellite is pointing when one of its bands receives a light signal from a particular spot on earth.
- Analyzed the response of VIIRS to polarized light.

**Sr. Multidisciplined Engineer II, **El Segundo, CA** **(2003-2005)

Worked on various projects pertaining to radar and location of air and ground targets.

- Performed analysis on a simulated space-based radar (SBR) platform, proposed to be built around 2015. Developed and wrote Matlab code for simulation.
- Ran software simulating the detection of ground targets.
- Completed a six-sigma project on code for analyzing the SBR.

**WOLFRAM RESEARCH, **Champaign, IL

Inventors and Makers of Mathematica, software for performing mathematical calculations with numerous applications in both industry and education, for students, engineers, and scientists.

**Kernel Developer **2000-2003

Developing and improving computer code and developing and implementing algorithms for performing various types mathematical calculations.

- Wrote code to factor large integers, developing and implementing a special factoring algorithm called the quadratic sieve.
- Implemented new algorithm for computing the greatest common divisor of two large numbers.
- Wrote code to perform polynomial arithmetic.
- Wrote number theory code.
- Wrote a cryptography add-on package which implemented several cryptosystems such as RSA, Diffie-Hellman, El Gammal, and Cayley-Purser.
