About me

I am Ph.D. student at IDIAP jointly with the École polytechnique fédérale de Lausanne (EPFL). I am working on a European Union Horizon 2020 project called ATCO2. It is dedicated to the development of an Automatic Air Traffic Speech Recognition system. Also, we aim at developing a unique platform allowing to collect, organize and pre-process air-traffic control (voice communication) data from air space (and yes! air traffic communications are a challenging task!).

Originally from Baranoa, Colombia. A tiny village in the North of Colombia (around 30 minutes from the Caribbean coast). I received a B.S. in Mechatronics Engineering from Universidad Autonoma del Caribe and an M.Sc. also in Mechatronics Engineering, but this time from University of Oviedo in Spain.

  • January: Started my Master Thesis at the École nationale supérieure de mécanique et des microtechniques in Besançon, France! I will work on computer vision for breast cancer diagnosis!

2017

  • September: Arrived in Gijon, Spain to start a Master’s degree in Mechatronics Engineering! Gijon is such a nice coastal town!

  • January: I got the exciting news that I was accepted at the The Joint Master Degree in Mechatronic Engineering, EU4M. This program allows students to select from 2 to 3 (out of 5) universities where to go for studies. I will start at the University of Oviedo in Spain, then I will go to ISPU (Ivanovo, Russia) and finally to ENSMM in France!

2010-2015

  • Started and finished a Bachelor’s degree in Mechatronics Engineering! I learned tons of things about electronics, mechanical engineering, robotics, and programming languages (C, Python, and Matlab)!
