Dr. Yonggang Liu currently serves as the Director of the Ocean Circulation Lab at USF College of Marine Science. He is a physical oceanographer, aiming to better understand the ocean circulation on the West Florida Shelf, including the interactions/exchanges of water properties between the estuaries, the shelf, and the offshore (Loop Current) system of the Gulf of Mexico. He uses both in situ observations and numerical models in coastal ocean research, and he is interested in applying physical oceanography to marine environmental issues, such as wastewater plume modeling, oil spill tracking and Karenia brevis red tide predictions. He also develops and applies novel data analysis methods in meteorology and oceanography. Dr. Liu is an Associate Editor for AMS Journal Artificial Intelligence for the Earth Systems (AIES), and a Guest Editor for Elsevier Journal Deep-Sea Research II. He previously served as an Oversight Editor of AGU Geophysical Monograph Series and was on AGU Book Board Committee. He is presently on SECOORA Science Committee and SECOORA SOCAN Stakeholder Committee.

Postdoc associate opportunity: New!

We seek a PhD level research associate in coastal ocean circulation modeling and analysis. Candidates with numerical modeling experience using FVCOM are preferred. More info can be found from the official ad.

Graduate student opportunities:

Motivated scholars are encouraged to apply for the MSc and PhD graduate student positions in our lab. Examples of exciting research topics are:
  • Integrated analysis of data obtained from moored array, HF radars, gliders, satellites, and model output
  • Coastal ocean circulation modeling & data assimilation using unstructured grid FVCOM
  • Coupled ocean current & wave modeling
  • Water quality observing and modeling
  • Biological modeling of Florida red tide (Karenia brevis harmful algal bloom)
  • Gulf of Mexico Loop Current system and its interaction with the continental shelf

Red tide research:
