Ariel Waissbein

Brief Bio
Currently, I work as an expert researcher at Corelabs, the research laboratories of Core Security Technologies; and I teach at Instituto Tecnológico Argentino (ITBA). I took part of the TERA research group and currently research with some of its members. I am a Ph.D. student in the "Facultad de Ciencias Exactas y Naturales" school of the Universidad de Buenos Aires.
