Senior Applied Physicist


OBJECTIVE I am seeking a Senior Technical Position in optical instrumentation, optical systems, 3D technical modeling and visual simulation, and/or computer algorithm development.

CAREER
SUMMARY
  • Equally hands-on in the lab as well as fingers-on with computer analysis development
  • Experienced designing, implementing, and using advanced electro optics based equipment in the commercial and scientific instrumentation arenas for metrology, visualization, and imaging
  • Competent in the relevant skill sets: optical systems modeling, interferometry, metrology, data acquisition, and computer algorithms and software
  • Skilled at writing specialized 3D analysis codes for optics, opto-mechanics, and ray propagation on multi-core computers. For example, I wrote the virtual reality program NASA used to fix the Hubble Telescope.

EMPLOYMENT HISTORY

Microsoft Research
Hololens Project
Technical Contracting
Apr17
to
Present
Advanced computer simulations in support of verifying experimental engineering models.

COSTAR
Scientific And Technical Consulting
14Jul14
to
Apr17
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 visualizatin and ancillary numeric studies performed in MATLAB.

NANOMETRICS INC
Research Scientist
19Sep13
to
7Jul14
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 multi-core processor environment, illuminate the mysteries of small spot size formation in the integrated process control instrumentation industry.

4Jan10
to
18Sep13
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 RESEARCH INC
Senior Applied Physicist
19Oct05
to
3Dec09
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.

CONSULTANT/CONTRACTOR
19Oct02
to
18Oct05
Analyzed a 100m aperture telescope with novel 3D optical software tools I developed. Wrote for Version 1 of the IBM-Sony-Toshiba Cell Processor User's Manual, the chapter on programming the Synergistic Processing Elements, (i.e. the parallel processing hardware and programming concepts.)

LOCKHEED MARTIN ADVANCED TECHNOLOGY CENTER
Senior Staff Electro-Optics Engineer
Sep99
to
18Oct02
Architected and implemented an adaptive wavefront control brassboard instrument for real time imaging through the atmosphere using optical MEMS. Responsible for optical systems definition and software development of acquisition and processing algorithms. Contributed lab and systems engineering studies to the architectural definition of the James Webb Space Telescope. Directed a small group of junior staff and provided technical leadership to project.

CONSULTANT
Jul98
to
Sep99
Engineering capability assessments to NASA Goddard for synthetic assembly of satellite designs, Jul-Sep 98

CIRRUS LOGIC
Member of the Technical Staff
1997
to
Jul98
Successfully participated on design team for a PC 3D graphics accelerator chip. Authored OGL algorithms (hidden line removal, scanline processing, texture mapping, etc) in the assembly language for the pipelined, distributed parallel processor architecture. Applied rendering codes to study of optimum hardware texture cache sizes.

HEWLETT-PACKARD LABS
Consultant and Visiting Scientist
1995
to
1997
Invited (twice) by Hewlett-Packard to develop an interactive visualization system with force feedback (haptics) for CAD and opto-mechanical synthetic assembly. Responsible for project definition and direction, including real time collision detection algorithms and 3D visualization software authoring, and internal and external technology evangelization. Represented HP Labs at SIGGRAPH 96 with an interactive Ford Mustang demonstration, and a synthetic wrench/bolt bimodal display at AUTOFACT 95 and HP/CONVEX 95.
