During his undergraduate studies, he conducted an academic semester at the Technical University of Ilmenau, Germany (Technische Universität Ilmenau) through an exchange program. His undergraduate thesis, "3D Reconstruction: Implementation of a monitoring system for translating a 2D ultrasonic transducer", consisted of a system that recorded the position of an ultrasonic linear transducer during an examination in order to reconstruct the volume of the region being scanned registering an interpolating B-mode ultrasound images with the position coordinates. He has recently obtained his M.Sc. double degree in Mechatronics Engineering from Pontificia Universidad Catolica del Peru and Technische Universität Ilmenau.
