I direct the Autonomous Systems Laboratory (ASL). We design and build free-swimming robots.
I have always loved marine ecology and biomechanics, because they are so interdisciplinary. Inspired by Ken Sebens and Steven Vogel, I like asking questions that require new technology to find the answer. Serious students of the history of science know that this is usually how science advances: new instruments lead to new insights that often spawn whole disciplines, rather than vice versa. For the last decade, I have been developing Autonomous Underwater Vehicles (AUVs), free-swimming robots that survey the bottom and water column in ways superior to previous approaches like towed bodies or lowering an instrument over the side of a ship. I am convinced that AUVs are oceanography’s most important recent technological advance. The ASL has used AUVs to make new discoveries such as coherent structuresr of lowered oxygen over coral reefs, how krill swarms in the Antarctic appear on high frequency side scan sonar, and how to identify fishes from their side scan sonar images using neural network processing. This last area is poised to become a new tool for fisheries stock surveys.
AUVs are the mobile components that will be vital to filling in the gaps between the fixed nodes of Ocean Observing Systems. The ASL is currently working on expanding our ability to recognize everything an AUV sees with its sensors, to detect anomalies and respond to them (for it is the anomalies that often herald interesting things the ocean is doing), and to develop efficient methods for AUV sampling of pressing environmental problems like coastal hypoxia, the growth of gelatinous zooplankton populations, and coral reef degradation.
Current initiatives of the ASL include 1) developing a deep-sea autonomous vehicle swarm that can persist on-station for months, and return thousands of miles back to shore with physical samples, using a radical new approach to AUV design, 2) biologically-inspired autonomy whereby behaviors and structures by evolved organisms as diverse as salps, squids, sponges, fishes, marine mammals, and marine reptiles can increase the robust intelligence of AUVs, 3) new software for coordinating AUV swarms (CARNIVORE), and 4) developing methods to thwart the misuse of unmanned systems by terrorists.
The physical biology of invertebrates (sponges, cnidarians, squid), plants (macroalgae, sunflowers, seagrasses), and fishes is another area in which I am broadly interested. The allometry of metabolism is an area where I apply chemical engineering theory to lower aquatic invertebrates and algae. Contrary to the predictions of “universal scaling laws” that have appeared in the literature, e.g., the West, Brown, Enquist (WBE) theory, these taxa do not follow 3/4 power scaling of metabolic rate with body mass. Instead they exhibit a diversity of scaling exponents for which I have developed a predictive theory based on first principles from fluid transport and mass transfer. This “flow modulated allometry” model is now being tested in my laboratory and in the field using the NOAA underwater habitat Aquarius. Since 1984, I have used saturation underwater habitats to conduct research in situ on corals and their allies. Recent work using Aquarius has examined how reef corals respond to water motion during bleaching episodes by altering their photobiology and expression of stress proteins. Our lab has recently developed a predictive electrical network model of the gastrovascular system of corals of the two types of coral bauplan, perforate (where an extensive plumbing connects the polyps) and imperforate (where polyps are not connected directly). This model will help us understand how corals respond to environmental stress including that posed by global warming and ocean acidification.
During 2008, I spent my sabbatical in Iceland working with Jörundur Svavarsson (University of Iceland) and Daniel Jones (National Oceanography Centre, UK) on a new kind of shallow-water hydrothermal vent (high pH and temperature, low salinity, precipitating smectite), only found (so far) in one fjord on planet Earth. We demonstrated that we can detect vents efficiently using an AUV, and gathered preliminary data on the biological and chemical environment around the vents, including biodiversity and trophodynamics. We hope to continue work on this system that requires an interdisciplinary approach between marine robotics, benthic ecology, geology and physical oceanography.

I am also a mentor to the NASA Knights, a FIRST Robotics Team, which helps ensure a supply of engineers for the country's future.
- Flock of Dodos: the Evolution/Intelligent Design Circus, a film by Randy Olson, a genius at communicating science to the public. I participated in this documentary on-screen, and helped the filmmaker with appearances at screenings as a panelist. This film is an insightful, humorous, but ultimately serious examination of how scientists are failing to communicate with the public on this important subject.
