We develop new propulsion methods to enable both flight and underwater locomotion in robots, with a particular focus on transitions & bio-inspiration. We are currently solving challenging transition questions through experimental methods and are studying autonomy, simulation and integration aspects.
The ultimate objective of our robotic systems is to operate in our ocean and waterways without user intervention, and have a positive impact for oceanographers, biologists. To this end, we seek to understand how non-intrusive, small-scale systems can deliver high quality data in a cost-effective manner.
Current projects and future research directions for the lab.
A Flapping-wing Aerial Aquatic Vehiclecapable of both flight and swimming. The first robot of it's kind to successfully transition from water to flight.
A large-scale flapping wing robot designed to answer questions in both controls and actuation.
An environmental sampling and monitoring active stabilizing hydrofoil. A highly efficient and low-cost surface vehicle.
An exploration of swarming of aerial aquatic vehicles for environmental monitoring and ocean exploration.
Highlights of past research projects. List of publication on ORCID and Google Scholar.
Large-scale flapping-wing robots with physical contact capabilities. Perching on a branch has been achieved!
A novel water-reactive fuel thruster for impulsive take-off, allowing multiple jump-gliding from the water surface.
Sailing-Flying locomotion method for long-duration aerial-aquatic missions thanks to wind energy harvesting.
Aquatic escape of a 160 milligram robotic bee using flapping flight, hydrogen combustion and electrolysis.
I am looking for motivated students that are excited to study and develop the next generation of hybrid autonomous systems.
A new graduate class, offered for the first time in Fall 2026, that treats flight and swimming as
two sides of the same fluid dynamics problem. Students work through the full robot development
stack end to end - motor control, wing design, fabrication and waterproofing - and the
semester closes with a competition on swimmer speed and efficiency.

The cornerstone undergraduate design class, taught in the spring, where students build competence
and confidence as design engineers through a major design-and-build project. Topics span idea
generation, estimation, concept selection, CAD, mechanism design, machine elements and basic
electronics, and the term ends with the traditional 2.007 robot competition.
