CS Education

I graduated with a Ph. D. (2011) and a M.Sc. (2009) degrees in Computer Science and Engineering at the University of South Florida under supervision of Prof. Dr. Miguel A. Labrador. My undergraduate studies are in Systems Engineering from Universidad del Norte - Barranquilla (Colombia) in 2006. My undergraduate research mentors at UniNorte were Prof. Carlos Ardila-Hernandez and Prof. Dr. Yezid Donoso-Meisel.

My main research interests are:

          • Privacy / Cybersecurity

          • Mobile/Ubiquitous Computing and Sensing

          • CS Education, in particular teacher education for middle/high school CS

My secondary research interests are:

          • Machine Learning and its applications to Human-centric systems, privacy and cybersecurity

          • Multiobjective Optimization and its application to Computer Networks and Scheduling
