For the first time ever astronomers have studied an asteroid that has entered the Solar System from interstellar space. Observations from ESO's Very Large Telescope in Chile and other observatories around the world show that this unique object was traveling through space for millions of years before its chance encounter with our star system. It appears to be a dark, reddish, highly-elongated rocky or high-metal-content object. The new results appear in the journal Nature on 20 November 2017. ...

Twice as big as Earth, the super-Earth 55 Cancri e was thought to have lava flows on its surface. The planet is so close to its star, the same side of the planet always faces the star, such that the planet has permanent day and night sides. Based on a 2016 study using data from NASA's Spitzer Space Telescope, scientists speculated that lava would flow freely in lakes on the starlit side and become hardened on the face of perpetual darkness. The lava on the dayside would reflect radiation from th...

Landing on Mars is difficult and not always successful. Well-designed advance testing helps. An ambitious NASA Mars rover mission set to launch in 2020 will rely on a special parachute to slow the spacecraft down as it enters the Martian atmosphere at over 12,000 mph (5.4 kilometers per second). Preparations for this mission have provided, for the first time, dramatic video of the parachute opening at supersonic speed. The Mars 2020 mission will seek signs of ancient Martian life by investiga...

A temperate Earth-sized planet has been discovered only 11 light-years from the Solar System by a team using ESO's unique planet-hunting HARPS instrument. The new world has the designation Ross 128 b and is now the second-closest temperate planet to be detected after Proxima b. It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life. Ross 128 b will be a prime target for ESO's Extremely ...

What seemed at first like a rare instance of a huge, ancient galaxy revealed itself to be an even rarer pair of extremely massive galaxies, seen on the brink of merging when the Universe was only a billion years old. This outstanding source was first identified by ESA's Herschel space observatory, and later exposed in greater detail with the ground-based Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. The earliest galaxies in the 13.8 billion-year history of our cosmos starte...

    Work Experience

    Design and Development Engineer at ASP Equipment

    15/09/2013 – On going

    Development of power converters for Aerospace applications. Definition of specifications, design according to specifications, verification and validation through prototyping, circuits test.

    Young Graduate Trainee at ESA Power & Energy Conversion Division

    01/09/2012 – 31/08/2013

    Research on distributed power systems and development of an intermediate bus converter to split the energy conversion chain in two different stages. A theoretical study was carried out to identify when this architecture improves the overall efficiency given by a single stage converter and the features that this converter should have to maximize the overall efficiency. Afterwards some prototypes of the most promising options were built to validate the results.

    Research assistant at Power Electronics System Group (GSEP) of Universidad Carlos III de Madrid

    01/11/2011 – 31/08/2012

    Research and design of different control architectures for distributed DC-DC converters for train applications. Modelling of the distributed system.

    Intern at Siemens Energy Distribution Business

    31/01/2011 – 30/09/2011

    Bids for medium voltage switchgears in energy distribution projects. Technical support for proposals and reviews. Follow-up projects and orders.

    Private teacher (self-employed)

    01/01/2007 – 31/07/2012

    Groups and individual lessons.

    Shop assistant at H&M

    01/06/2005 – 31/12/2007

    Customer assistance. Daily planning. Warehouse organisation.

    Education and training

    Industrial Engineering in Electronics and Automation at Universidad Carlos III de Madrid

    01/09/2005 – 01/10/2011

    Five years degree with solid background in Mechanics, Electrical systems, Energy Technologies, Thermal Engineering and Industrial Business and Management apart from Electronics and Automation which is the intensification that I chose. Most relevant courses: two modules of Analog Electronics (fundamentals of semiconductors, amplifiers, frequency analysis,  stability, negative feedback, oscillators, filters), two modules of Digital Electronics (logic gates, memories, finite state machines, microcontrollers) , Electronic Instrumentation (signal conditioning, modulation and demodulation, data acquisition and conversion systems, transducers), Power Electronics (DC-DC, AC-AC, inverters, rectifiers, control of power converters), three modules of Industrial Electrical Systems (magnetics, transformers, electrical machines, electrical systems), several modules of control engineering and automation (dynamic modelling systems, stability, control systems) and finally several modules of automation and electronics laboratory.

    My undergraduate thesis was carried out at GSEP with the title of DC-DC converter for micro-satellites electric thrusters. This converter was intended to adapt the low voltage energy produced by the solar array to a high DC voltage demanded by the electric thruster. The most prominent features of this converter are its high voltage gain and low power. This work comprised of an initial research on the state of the art, a theoretical study accompanied by simulations, design and an open loop prototype.
