Experience

Omdena Collaborations

Engineering Volunteer

Reviewed literature, implemented prototype models and pipelines for an AI-based landslide detection and warning system implementing multispectral optical, ultraviolet, and synthetic aperture radar satellite-based data.

U.S. Army

Mathematician

Developed, modeled, and proposed emergent unsupervised deep learning-based EW techniques and a suite of strategically relevant wideband waveform capabilities concerning a mobile solid state radar system. Designed and implemented a prototype integrated CV-NLP architecture via a novel generalized factorized hierarchical variational autoencoder instrumented together with SOTA fine-tuned multimodal foundation LLMs.

RTX Corporation

Senior Engineer

Developed an integrated microwave transceiver UPA, acoustic ULA and UCA, optical and IR sensors with novel fusion techniques for ML spatial awareness and object recognition using image processing techniques in Python. Identified more than $8 million in total annual product maintenance cost savings opportunities by modeling an extended operational range of mission-critical components for tactical avionics signal processors in MATLAB-based simulation suites in a Linux environment. Developed I/CRAD proposal and prototype material for a recursive filter involving a wideband refined adaptive beamformer technique.

Lockheed Martin Corporation

Engineer

Designed, implemented, validated, and live-system tested SOTA localization and wideband electronic protection algorithms and recursive filters in C/C++ and MATLAB-based simulation suites and tactical codebases in a Linux environment addressing emergent threats for tactical combat radar signal processors, their digital twins, and a suite of end-to-end sensor simulation products directly leading to a significant new contract award. Developed requirements specifications for future weapons systems via analysis of aggregate subsystem-, simulation-, and model-generated datasets. Delivered, designed, implemented and formally validated and verified both a componentization and productization of legacy models and a cross-model subsystems integration effort for the U.S. Missile Defense Agency. Designed adversarial attack for deep learning characterizations of ICBM threats.

Projects

Video-based talk therapy

The aim of this work is to develop a social and emotional regulation network using a prototype platform for detecting, tracking, and classifying socioemotional data. Initial efforts are directed toward unsupervised learning with variational autoencoders as a precursor to establishing a theraputic constitution. Our autoencoding facilities are designed to capture complex human behaviors within the space of physical gestures and utterances specified at the lowest temporal scale by instantaneous face, body and pose landmarks and phonemes.

Unsteady aerodynamics: An approximation of lift during oscillatory plunging

A framework for the derivation of the so-called Theodorsen function is provided. The function is investigated using numerical techniques. Numerical simulations of unsteady aerodynamics in two dimensions are provided. Note: This file has embedded video content that can be accessed using Adobe Reader. Since the file is large, it is stored off-site in Google Drive.
