Reinaldo (Rei) Sanchez-Arias

Assistant Professor of Data Science

Florida Polytechnic University


I am an Assistant Professor in the Department of Data Science and Business Analytics at Florida Polytechnic University (Florida Poly). Before joining Florida Poly, I served as the Program Director for the MS in Big Data Analytics in the School of Science at St Thomas University (STU) in Miami. I was also part of of the Applied Mathematics Department at Wentworth Institute of Technology (WIT) in Boston, and completed a postdoctoral researcher appointment for the Army High Performance Computing Research Center (AHPCRC) at The University of Texas at El Paso (UTEP) in collaboration with a group at Stanford University. Research projects for the AHPCRC involved global optimization and parameter estimation, reduced-order modeling, and data analytics.
