I work at the College of Engineering and Applied Sciences (CEAS) at the State University of New York (SUNY) at Stony Brook, as well as in the Department of Mechanical Engineering. Previously, I was a research associate in the BioMEMS Lab, part of the Biophysical and Biomedical Measurements Group at the National Institute of Standards and Technology NIST. I obtained my Ph.D. in the Charles L. Brown Department of Electrical and Computer Engineering at the University of Virginia, advised by Professor Nathan S. Swami, Biophysical Microsystems Group. I work on developing microfluidic systems to measure various biophysical and/or condensed-matter properties, as well as electrokinetics-based techniques for particle and microstructure manipulation. I received my B.Sc. (Lic.) in Chemical Engineering at the Universidad de Costa Rica and a M.Sc. in Micro-electromechanical systems (MEMS) at the Tecnológico de Costa Rica. Previously, I spent 8 years working as an engineer in the private and public sectors. Email contact: karina.torrescastro@stonybrook.edu
