Pierre-Yves Passaggia, Post-doctoral Scholar

Pierre-Yves is a visiting post-doctoral scholar from France. His work at UNC focuses on the mixing dynamics in horizontal convection. His research includes theoretical, numerical and experimental aspects on gravity driven flows with a special emphasis on stability and transition to turbulence. With a Ph.D from IRPHE/Marseille University in fluids dynamics and its control, work experience at the French aerospace agency Onera on uncertainty quantification, Pierre-Yves also interacts with the Medical University of Grenoble and collaborates with a research team on non-invasive measurement techniques for the treatment of the hydrocephalus disease. He has published 10 publications in peer reviewed journals in fluids dynamics and applied mathematics. Focusing his career on research and teaching, Pierre-Yves enjoys working with students and scholars from different backgrounds as well as collaborating with industry on topics related to his research.

Varvara (Barbara) Zemskova, Graduate Student

Barbara received her undergraduate degrees in Environmental Science and Applied Mathematics from the University of North Carolina in Chapel Hill. Her undergraduate work focused on freshwater systems, including fieldwork experience in stream and lake ecology at Flathead Lake Biological Station through the University of Montana, and modeling the transport of a TCE-contaminated groundwater plume for a REU project at the University of New York at Buffalo. As a graduate student, her interests shifted to physical oceanography. Her current research project focuses on studying contribution from wind and buoyancy forcing to diapycnal mixing in the ocean through the analysis of satellite data, MITgcm model outputs, and Direct Numerical Simulations. In 2014 she was the recipient of a Blue Waters Graduate Fellowship through the National Center for Supercomputing Applications. She was also a graduate fellow at the Geophysical Fluid Dynamics program at Woods Hole Oceanographic Institution in 2013, where she modeled double diffusive convection of iron layers in a stellar outer core.

Elaine Monbureau, Graduate Student

Elaine is a PhD student investigating gravity current intrusions into stratified ambient systems. Her laboratory experiments are conducted in a 27 meter section of the UNC Joint Fluids Laboratory wave tank and employ particle image velocimetry and laser induced fluorescence to track and quantify the complex interactions. These results are comparable to river plume discharge into the ocean and the laboratory results are compared to computational fluid dynamics simulations. She received her B.S. in Physics and her Master’s degree in Observational Physical Oceanography. Her somewhat eclectic background includes research in the medical sciences, as a programmer, data analyst, fabricator and designer of measurement equipment, and clinical technician.  She loves her wonderful daughter, hiking in National Forests, and her two annoying cats.

Si Chen, Graduate Student

Si is currently working on a project of marine aggregate formation under turbulence based on PIV/PTV technology. He is interested in fluid flow of different scales and is trying to obtain deep insights with theoretical, experimental and numerical tools. He is also a poet and would like to record his feelings with pencils and notebooks.
