| STANFORD LINEAR ACCELERATOR CENTER |
| LCLS II |
| |
|
Wrote a 3D raytracing visualization and analysis software package in Matlab to support engineers in the design and certifcation of the safe operation of the LCLS II x-ray laser beamline. Gave presentations of results and collaborated with engineers on specification and feature set of this software package. |

Wrote advanced computer simulation softwares in support of verifying experimental engineering models. Matlab based with GUI (GUIDE) and parallel processing support. |
|
| NANOMETRICS INC |
| |
|
Wrote partially coherent imaging software to study optical design parmeter space for instruments such as spectral ellipsometers, scatterometers, and some forms of microscopes. I've written these codes using CUDA to run on GPUs for computational acceleration. These codes were primarily written in C with visualization and ancillary numeric studies performed in MATLAB. |

Highly engaged in computational optics, wherein I wrote diffraction-imaging numerical simulation codes for spectral ellipsometers, capturing partial coherence, imaging on tilted planes, apodization, and 3D mechanical tolerancing. These codes, written for a Wintel multi-core processor, illuminate the mysteries of small spot size formation in the integrated process control instrumentation industry.

Contractor to a recognized DNA sequencing company both implementing AND analyzing an ultra-high precision metrology instrument to measure optical geometric distortion for manufacturing qualification of their low fluorescence microscope objective. Starting with ZEMAX analysis outputs, I wrote a multi-threaded analysis program to model axio-spatially variant PSFs to calculate instrument response to real pixel structures. (Translation: this is an unambiguous example of successfully merging both in-lab E-O instrumentation skills and 3D computer modeling of the project.)
Authored a 3D altimetry waveform generation package for an international satellite-borne altimetry project.
Wrote a motion control package in Python using a Newport actuator solution for the SEMATECH EUV Micro Exposure Tool 5 (MET-5) Project
Conducted a project to verify simulated radar altimeter waveforms using 3D databases and my virtual radar codes with actual data.

Vista closed its Sunnyvale office when it lost government funding on termination of the Virtual Fence Project.
Authored 3-D ray propagation simulation softwares for these applications: 1) propagation through continuous media using differential ray propagation (i.e. not a shell model,) 2) ground radar systems performance (virtual radar), 3) Doppler signature calculation of walking and running humans, and 4) urban canyon environment modeling (buildings and vegetation) to predict echo returns for a multipath exploitation radar program. These codes were developed for a multi-processor, multi-core platform.
Co-inventor of US patent 8026844, 'Radar Visibility Model.'
High precision calibration of line of sight errors (optical geometric distortion) and alignment of an infra-red poly-camera for surveillance applications using diffractive optics reference standards. Responsible for all phases from concept to execution, including component acquisition, laboratory setup, data analysis software, and reporting.
