James Liao, Ph.D.

The Liao Lab will contribute to the iCoast program by leveraging biology to augment the existing, hardware-based, autonomous maritime monitoring capabilities currently being developed by UF Engineering. Our program will tap into fish and other marine organisms’ innate abilities to sense and respond to perturbations in their environments (red tide, hurricanes, etc.), with the idea that these organisms have evolved for millions of years in these habitats, and are uniquely sensitive to abiotic and biotic changes that stimulate their migration and physiological states across seasons. Leveraging the sensory capabilities of these organisms as “canaries in the coal mine” makes great sense: biological organisms are cheaper, more sensitive, do not foul, are self-replicating and largely self-sustaining, do not need deployment, and run for longer than any mechanical device that humans can currently manufacture. What is required is the ability to translate and interpret observed behaviors from a biomechanical and neurophysiological perspective. This is the expertise of the Liao Lab, which is poised to provide persistent undersea surveillance with a minimal logistical footprint.

Dr. James Liao is an Associate Professor in Biology, UF Term Professor 2016-2019, Affiliate Professor in the Crayton Pruitt Family Department of Biomedical Engineering, and Affiliate Curator of Ichthyology at the FLMNH. He joined the UF Faculty in 2009 after being an NIH NRSA postdoctoral fellow and research associate in the Neurobiology and Behavior Department at Cornell University. Prior to that, Dr. Liao received his M.A. and Ph.D. in Biology at Harvard University, where he was recognized with multiple Derek Bok Excellence in  Teaching Awards. His undergrad was at Cornell, James Cook University (Australia) and Wesleyan University (96' magna cum laude).

The research of Dr. James Liao looks at the physics and neuroscience of how animals sense and navigate the world. One component of his research looks into how fish can recapture the energy of turbulent flows to provide insight into how to better build underwater robots. He is currently extending this work to better understand the sensory capabilities and migratory behaviors of wild fishes in north Florida. Another part of his research looks at the organization and function of neurons in the lateral line hair cell system in fish. These hair cells are identical to those found in human ears but are much more experimentally accessible. Powerful technological and genetic advances make it possible for the first time to look into the nervous system of living vertebrates and ask questions related to human deafness and balance disorders.

Maitane Olabarrieta, Ph.D.

Olabarrieta and her graduate students, Luming Shi and Chu-En Shu, are working on the development and establishment of a coupled wave-hydrodynamic-ecologic forecast modeling system within the iCoast project. This forecast system is being stablished and tested in the Guana-Tolomato-Matanzas estuary, and it will be used to forecast surfzone hydrodynamics, impacts of storms (erosion and flooding) and water quality. The forecast system will be used to gain understanding of the dynamics of the estuary under diverse weather conditions. The information provided by the forecast model will serve to stablish a warning system against the impacts of storms, algal bloom outbreaks and excesses of water pollution.

Maitane Olabarrieta is currently an Assistant Professor at the Civil and Coastal Engineering department at the University of Florida. She received her Ph.D. from the University of Cantabria (Spain) in 2006.  Her research interests cover diverse oceanographic and long-term morphodynamic evolution problems that affect our coasts. By combining remote and in situ measurements and numerical modeling, she and her students study processes with a wide variety of spatial and temporal scales, including momentum exchange processes during hurricanes and extreme storms, the generation mechanisms of meteotsunamis, short-term estuarine transport processes, wave-current interaction, inlet dynamics and the long-term evolution of tidal networks and inlets. One of the main goal is to improve numerical models used to predict the transport of pollutants and sediments in inlets, coastal change, erosion and flooding. Within the Coastal Morphodynamics Lab, undergraduate and graduate students combine advanced numerical modeling, field surveys and remote sensing to analyze the feedbacks between the hydrodynamics, sediments transport and coastal morphology. During her research career, Olabarrieta has collaborated with several research groups from Europe, the United States, New Zealand, China, and Australia. In 2015 Maitane received the NSF CAREER Development Award, which has provided her the unique opportunity of analyzing the morphodynamic evolution of mix-energy inlet systems.

Thomas Bianchi Ph.D.

Dr. Bianchi will be using chemical biomarkers to track input of local septic systems in the St. Augustine region. Sterols have been shown to effective chemical biomarkers of different sources of organic matter in coastal systems.  In particular, their application in tracing the sources of sewage and waste waters inputs has become more common in recent years. Here, we use coprostanol, and other related derivative sterol compounds, as tracers of sewage inputs to the Matanzas River.  We will track sewage sources (e.g., agriculture versus human) by analyzing sterols in both dissolved and particulate organic matter (from surface and bottom waters), as well as in select surface sediments.  Sterols (analyzed using GC-MS-MS) will also be linked to other measured parameters in this study such as, dissolved inorganic nitrogen, the relative abundance and strains of E. coli and, human-sourced hormones.

Thomas Bianchi is a full professor and holder of the Jon and Beverly Thompson Endowed Chair in Geological Sciences at the University of Florida (UF), Gainesville, Florida.  Before joining UF I held full professor positions at Tulane University and Texas A&M University. My general areas of expertise are organic geochemistry, chemical oceanography, and global carbon cycling in aquatic ecosystems.   I have published over 220 articles in refereed journals and am sole and/or co-author of 7 books, with another book on Chemical Oceanography of the Gulf of Mexico - due out in 2019. I am currently Editor-in-Chief of the journal Marine Chemistry, and have served as an Associate Editor for numerous other journals.  I am the recipient of two Fulbright Research Awards, became a Fellow of the American Association for the Advancement of Science (AAAS) in 2012, and in 2017 was named Geochemical Fellow of the Geochemical Society (GS) and The European Association of Geochemistry (EAG), Fellow of the Association for the Sciences of Limnology and Oceanography (ASLO), and in 2018 was recipient of the Qilu Friendship Medal/Award from the Shandong Province of China.

Many of the central issues in research concerning global climate change involve understanding the exchange and transport of organic and inorganic pools of carbon – in the context of the global carbon budget. If we are to successfully balance and model global carbon fluxes, it is important to understand the dynamics of carbon cycling in the most productive environments. In general, the most productive environments are located in land-margin ecosystems such as watershed soils, freshwater, and marine coastal systems. During the past few years my research has centered on organic carbon cycling from source-to-sink with work focused on the transport of soils in watersheds of large river systems to coastal environments. I have used state-of-the-art techniques to determine the role of terrestrial versus aquatic carbon sources in the overall carbon cycles of these ecosystems.

Nancy Denslow, Ph.D.

Dr. Denslow will be collaborating with Dr. John Bowden for the analytical determination of contaminants via various types of LC-MS/MS instruments.  Dr. Denslow will be performing targeted analytical analyses via LC-MS/MS to determine concentrations of synthetic and endogenous sex steroid hormones in the intercoastal region near St. Augustine.  This will be an additional measure of input into the intercoastal system from the sewage treatment facility in St. Augustine and from septic systems along a gradient towards the Whitney Laboratory in Marineland.  The specific endogenous hormones to be evaluated include estradiol, estrone, estriol, testosterone, 11-keto-testosterone, and equilin.  In addition, synthetic hormones that are usually included in the birth control pill will be evaluated including ethinylestradiol and levonorgestrel.  Water and sediments will be analyzed by LC-MS/MS.  We will cooperate with Dr. Bianchi’s group to analyze similar extracts.

In addition, Dr. Denslow will use cell-based assays for estrogen, androgen and progestin receptors to measure aggregated activities for these receptors (both sex steroid hormones and industrial contaminants that may mimic ligands for these receptors).  This will help identify chemicals of concern using  nontargeted mass spectrometric analyses.
