Modeling and simulation.
Design of experiments, negotiation with vendors.
End-to-end modeling & development of thermal management solutions for wearable consumer electronics.
Evaluation of emerging technologies.
Providing expertise in optimization and algorithmics, parameter estimation, model validation and classical and quantum physics.
Leading the creation, implementation, and statistical validation of a multiscale, rapid & agile diagnostics, modeling, and simulation architecture (the latter utilizing COMSOL, MATLAB as well as LUTs and co-simulation codes) for heat pipes and vapor chambers, both standalone and embedded within devices (for thermal management purposes).
2013-2015: Scientist, Oxford Associates, Mountain View CA
Microsoft Xbox Team: Made significant contributions to several projects involving Time Of Flight (TOF) depth camera modeling, calibration and operation, including: advanced multi-parameter optimization algorithms; predictive models of CMOS-APS (Active Pixel Sensor) scene-depth noise and multi-device interference; and image processing/machine vision algorithms for calibration and operation of TOF cameras.
Developed simulation platform for real-time analysis of GPS data and subsequent broadcast of FAA-required Receiver Autonomous Integrity Monitoring metrics (GPS-RAIM) from GA (General Aviation) aircraft.
2009-2013: Senior Scientist, Lightfar Cineonics
Developed algorithms for iPhone apps that combined DSP innovations in machine vision, computational geometry, Bayesian inference, and Joint Time-Frequency Analysis, as well as some biophysics modeling.
The iPhone videos analyzed by my algorithms were chemical and biophysical in nature, and the apps involved monitoring the environment and automated biomedical diagnoses.
2007-2009: Senior Scientist, Avago Technologies, San Jose CA
RF modeling; optimization and design of layered, multi-piezoelectric-resonator BAW filters for mobile phones, including 3D models and study of parasitic and nonlinear effects (harmonics, Inter-modulations, stray PCB interactions)
2003-2007: Senior Scientist, Vialogy, Pasedena CA
Development of model-based algorithms for denoising extremely low-SNR datasets. Work on mass-spectrometry data led to conference presentation and a patent. Later I applied similar techniques to geoseismic exploration data with high noise and clutter levels.
2002-2003: Audio Software Engineer, Tymphany Corp, Mountain View CA
Electromagnetic, electromechanical and acoustic modeling of various types of audio speakers, and development of speaker-cone position detection methods and firmware-implemented feedback linearization control algorithms.
2000-2002 Senior Staff Scientist C-Cor Electronics
