I've got my Electrical Civil Engineer degree with a specialization in Industrial Control Process, at the Universidad de Santiago de Chile in 2009. But during and after the university, I've been more involved in Electronic and Firmware design, working with microcontrollers and switching power supplies.

In 2009 I started to work at the company SING Ltda. There I worked in the develop of a Georeference Tracking System for Asset Tracking. In the project we used a GPS, a GPRS modem, a switching power supply with a battery charger, and a Rabbit microcontroller.

In 2010 I started to work as an Electronic Engineer II at the International ALMA Observatory, The Atacama Large Milimeter/Sub-milimeter Array.

"The Atacama Large Millimeter/submillimeter Array (ALMA) is an international partnership of the European Southern Observatory (ESO), the U.S. National Science Foundation (NSF) and the National Institutes of Natural Sciences (NINS) of Japan, together with NRC (Canada), NSC and ASIAA (Taiwan), and KASI (Republic of Korea), in cooperation with the Republic of Chile. ALMA -the largest astronomical project in existence- is a single telescope of revolutionary design, composed of 66 high precision antennas located on the Chajnantor plateau, 5000 meters altitude in northern Chile." - cited from http://www.almaobservatory.org/en

In ALMA I was in charge of the software devolpment of tools for diagnostic and maintenance of the antenna's receiver cartridges (Bands 3, 4, 6, 7 and 9, and the early stage of Bands 5 and 8). The software I wrote is now used to find the fine-tuned parameter for the SIS juntions to lower the noise termperature (Y-Factor) and Josephson Effect. It is also use to run the PAS (Procesdure of Acceptance on Site) when a new receiver is received.

As a research project, along with my supervisor, we developed a new algorithm to fine-tune in real-time the photomixer parameters (to lock the local oscilator's PLL) of each receiver. This device receive the master laser signal which set the observation frequency. This software replace the old LUT (Look-Up Table) based algorithm. You can find the paper in this link A new phase-lock algorithm for the ALMA receivers

At the end of 2012 I quitted ALMA to start an entrepreneurship project, but with no success. None the less It was a really good experience, and it is not going to be the last time I will try this.

In the mid of 2014 I joined the development hardware group for the ATaaS product line at Rhiscom. This project involved the development of robotics and comunication systems.

Since August 2017 I started my Ph.D. in Electrical Engineering at the Georgia Institute of Technology. Here my research areas of interest are Power and Signal Integrity, High-Efficiency DC-DC Converters, and Computational Electromagnetics. In may 2019 I received my Master of Science degree from the Georgia Institute of Technology in Electrical and Computer Engineering.
