What we work on

We study how unmanned systems learn, decide, collaborate, and stay safe, and we validate the answers on aircraft we build in the lab.

Learning, autonomy, and human-machine collaboration

Unmanned systems need enough onboard intelligence to cut human workload rather than add to it under SWaP constraints. We work on reinforcement learning, human-guided learning, multi-objective and fair policy optimization, and visual-language-model agents that are deployable in physical robotic systems. Recent work covers reward learning from human ratings, learning from failure, interpretable policy distillation, visual-language-action models, and inference-time policy alignment at deployment.

  • reinforcement learning
  • human-robot teaming
  • multi-objective RL
  • VLA agents
  • explainable AI
  • inference-time alignment

Guidance, control, and multi-agent coordination

The lab has a long record in distributed coordination, consensus, containment, and event-triggered control. Current work is in safety-critical control under input constraints, safety certificate, and energy-efficient flexible leader–follower formation.

  • nonlinear guidance
  • formation control
  • event-triggered control
  • safety-critical control

Cyber-physical systems and security

Connecting physical systems through the cyber domain creates capability and exposure at the same time. We study where the vulnerabilities are, what they cost operationally, and how to predict and mitigate them. Related work covers fault-tolerant control of uncertain multi-agent systems and resilient learning under corrupted data.

  • CPS security
  • fault-tolerant control
  • resilient learning

Trustworthiness and flight validation

Research moves into practice only if it is validated on real hardware in real conditions. The lab designs its own small aircraft, including the airframe, the flight control board with onboard computing, the software, and the sensing modules. We build the benchmarks, datasets, and test protocols that make a capability claim checkable by someone outside the team.

  • flight testing
  • hardware in the loop
  • benchmarks and datasets
  • verification and validation

Capability

Facilities and flight testing

The lab builds its own small aircraft end to end: the frame, the flight control board with onboard computing, the software stack, and the sensing modules. One team controls the compute carrier and the software, which is what makes a claim about onboard timing and autonomy measurable rather than estimated.
