Areas of Interest: Large-eddy simulation (LES) and direct numerical simulation (DNS) of turbulent flows, subgrid-scale modeling for LES, LES of turbulent mixing in environmental flows, physical, biological and chemical impacts of turbulent mixing in the ocean, integration of computations and field observations of turbulent mixing in the ocean, stabilized finite element methods for fluid flows, high performance computing.

 

Biosketch
Andrés Tejada-Martínez arrived at USF in Spring 2007 after serving as a post-doctoral researcher at several institutions. He obtained his Ph.D. from Rensselaer Polytechnic Institute where his research involved developing subgrid-scale models for LES of turbulent flows using stabilized finite element methods. At USF Tejada-Martínez has received a National Science Foundation (NSF) CAREER Award and various others NSF collaborative research awards for his work in LES of turbulent mixing in shallow shelf coastal regions and in the upper ocean mixed layer. Simulations are closely coupled with field observations with the goal of obtaining accurate parameterizations of the impact of turbulent mixing on physical, chemical and biological processes in the ocean. These parameterizations should be suitable for inclusion in regional and global climate models. Tejada-Martínez is also currently developing new methodologies and subgrid-scale models for LES and is involved in computational fluid dynamic analysis of abnormal fetal flows.
