Interests, selected work, and future directions
My research spans wireless communications, RF/microwave sensing, signal processing, and machine learning. I develop methods that turn noisy, incomplete measurements into useful information and evaluate them through mathematical analysis, simulation, and experiments with real data and hardware.
I view RF sensing and wireless-health monitoring as complementary parts of a sensing-to-action system: one describes the physical environment, while the other describes the connectivity supporting sensing, computation, and coordination. My longer-term goal is to bring them together through physical and agentic AI, with reliable local operation and selective use of cloud resources.

Wi-Fi health and decision support
My team and I developed an edge/cloud model for Wi-Fi health monitoring and optimal channel/band recommendation. The work connects wireless measurements to interpretation and actionable recommendations.
My contributions also include statistical and machine-learning frameworks linking gateway/client telemetry to WebRTC audio/video and set-top-box quality. These frameworks combine temporal features, application-quality labels, and controlled network experiments to investigate how signal quality, retransmissions, channel utilization, and rate dynamics relate to user experience.

Intelligent RF sensing for subsurface characterization
Within the USDA-funded SoilX project, I led signal-processing and machine-learning work for root-zone soil-moisture estimation from ground-penetrating radar (GPR). I helped develop radar hardware/software and data-acquisition pipelines, coordinated measurements and cross-institution collaboration, and mentored student researchers.
This work connects electromagnetic observations to estimates of physical properties for precision irrigation. Associated research received the IEEE ORSS 2023 Best Paper Award; subsequent publications investigate machine-learning-enhanced GPR analysis and wavelet scattering for soil-water-content prediction.

Secure and learning-enabled wireless systems
At the University of Houston, I developed GAN-based defenses for neural radio classifiers and evaluated them over the air on USRP software-defined radios. Our team earned first place in the constrained category of the AFRL Beyond 5G SDR University Challenge.
My collaborative work also addresses adversarial attacks on learning-based resource management, physical-layer security, UAV communications, rate-splitting multiple access, hybrid precoding, and privacy-preserving continual learning. These studies connect learning, optimization, and wireless design under reliability and security constraints.

Data-efficient computational radar imaging
My doctoral research developed joint SAR imaging and scene decomposition from undersampled measurements. Low-rank and sparse representations exploit scene structure to recover images and separate moving targets from stationary background.
My first-authored work in IEEE Transactions on Computational Imaging studies multi-feature decomposition and dynamic-scene video-SAR. Collaborative extensions address fast, robust SAR/ISAR reconstruction and real-time sparsity-driven imaging. This provides the model-based foundation for my interest in data-efficient learning and adaptive sensing.

Proposed research agenda
Building on these contributions, I am developing a research agenda around three connected directions. The emphasis is on experimentally verifiable decisions—not simply replacing domain models with a large language model.
Observe→Interpret→Learn & decide→Act→Evaluate & adapt
01Grounded edge agents for wireless health and adaptive connectivity
How can an agent turn incomplete wireless measurements into effective, verifiable interventions?
I aim to combine structured state estimates, validated diagnostic models, and constrained optimization with agent reasoning. The agent would determine what evidence is missing, recommend a channel/band or resource change, and assess its consequences. Time-sensitive tasks would remain local; higher-level reasoning would be invoked when useful.
02Adaptive RF/microwave sensing for physical AI
What should a sensing system measure next, and when does it have enough information?
I plan to combine electromagnetic models, sparse/low-rank structure, learned representations, and uncertainty estimates to guide radar acquisition. Measurement location, frequency configuration, and sampling density would adapt to the downstream task, beginning with soil-moisture characterization.
03Efficient and trustworthy edge/cloud computing
Which parts of a sensing-to-action system should run on a device, a gateway, or in the cloud?
I will investigate compact on-device inference, task-aware model reduction, adaptive offloading, and hardware/software co-design. Model confidence, network health, energy, and action urgency would guide execution placement, with runtime checks and bounded fallback behavior when conditions change.
Across these directions, I will evaluate complete sensing-to-action systems: the quality of the physical estimate or application experience, alongside decision latency, energy, communication overhead, and recovery from failures.
