Selected Research Contributions

Byte-Native Omnimodal Foundation Models

Developing byte-native, long-context foundation models that learn shared semantic representations directly from raw encoded data across text, imagery, audio, video, and arbitrary binary formats.

Key advancement: modality-agnostic semantic learning

Spatial Graph Reasoning for Detection

Introduced graph neural reasoning into object detection to encode spatial relationships among detections, reduce false alarms, and extend perception toward multimodal fusion and open-vocabulary prediction.

Key advancement: relational reasoning beyond independent detections

Complex-Valued Neural Components

Investigated neural operators that preserve complex-valued representations and phase information through forward and backward propagation for radar and signal-rich sensing problems.

Key advancement: learning directly in complex-valued domains

Fourier-Domain SAR Super-Resolution

Developed sequence-prediction approaches for estimating missing high-frequency Fourier components, enabling SAR super-resolution through signal reconstruction rather than conventional pixel interpolation.

Key advancement: predicted signal content instead of interpolating pixels

Cooperative Multi-Agent UAV Autonomy

Developed cooperative multi-agent approaches for distributed UAV sensing, resource management, mission planning, and persistent target custody in dynamic and contested environments.

Key advancement: decentralized coordination under changing priorities

Open-Set and Open-Vocabulary Perception

Developed perception approaches that recognize uncertainty, reject unknown objects, and expand beyond fixed class taxonomies through multimodal semantic alignment.

Key advancement: recognition beyond predefined classes
