In the first act of lunar exploration, Neil Armstrong and Buzz Aldrin were major characters. In setting its sights on the Moon, ESA hopes to bring many more actors to this off-world stage. By testing the market for transport services to the Moon, ESA aims to push the limits of technology and create new models of space business. Touching down on the Moon was a monumental moment in human history. Eight short years and enormous resources took humankind to the lunar surface, initially for le...

Astronomers have used ALMA to capture a strikingly beautiful view of a delicate bubble of expelled material around the exotic red star U Antliae. These observations will help astronomers to better understand how stars evolve during the later stages of their life-cycles. In the faint southern constellation of Antlia (The Air Pump) the careful observer with binoculars will spot a very red star, which varies slightly in brightness from week to week. This very unusual star is called U Antliae and...

The Sun's recent activity has caught the interest of scientists and space weather forecasters worldwide, highlighting the need to keep a watchful eye on our star and its awesome power. On 6 and 10 September, our Sun produced a pair of solar flares, the strongest observed in over 10 years. They were accompanied by huge eruptions of billions of tonnes of matter into space. While many such eruptions fall back onto the hot surface, these two did not and became 'coronal mass ejections' (CMEs) -...

NASA's Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt because it eats light rather than reflecting it back into space. This light-eating prowess is due to the planet's unique capability to trap at least 94 percent of the visible starlight falling into its atmosphere. The oddball exoplanet, called WASP-12b, is one of a class of so-called "hot Jupiters," gigantic, gaseous planets that orbit very close to their host ...

Launch is the most strenuous part of a satellite's life. To survive the extreme sound wave pressure and pounding vibrations generated by more than 700,000 lbs. of thundering rocket thrust, spacecraft need a solid, reliable design if they hope to arrive operational on orbit. On July 13, Lockheed Martin (LMT)'s second, fully-assembled GPS III space vehicle (SV) completed a realistic simulation of its future launch experience and passed this critical acoustic environmental test with flying color...

    SUMMARY
    I have been working in applied mathematics and physics for more than ten years. I have acquired this background through my experience in research fields such as, for example, astrophysics, signal processing and parameter estimation methods for time series. My programming experience spans algorithm development and test, and implementing numerical methods using physics principles in different programming languages as, for instance, C, C++, Fortran, Matlab and Maple.
     
    COMPUTER SKILLS
    Languages
    · C language: Since 1998 I have acquired knowledge and experience with C through some Bachelor and PhD degree subjects and research (in Physics and Engineering).
    · Fortran77: From 2000 until 2008 I have worked with Fortran 77 for numerical computation in order to solve differential equations, linear equation systems, matrix inversion problems and apply Bayesian statistics for modeling regression.
    · Bash: In order to install and use different software in different computers and clusters, I have got experience with Bash scripts.
    Software
    · Matlab: Since 2009 I also work with Matlab for modeling regression, numerical calculus, Bayesian statistics, MCMC simulations, data analysis and matrix calculus. Namely, I have developed and used algorithms for estimating parameters with Monte Carlo Markov Chain methods, linear regression
    modeling, spectral analysis of stochastic time series, matrix inversion, several matrix calculus algorithms such as, for example, Cholesky and iterative algorithms (e.g. conjugate gradient) and random number generators.
    · Others: Latex, Word, Excel, Power-Point, Maple.
    · OS: Linux (since 2000) and Windows (since 1995).
     
    EXPERIENCE
    15/11/2010-15/11/2013
    Senior Researcher, University of Luxembourg
    · I have worked on parameter estimation in stochastic time series, e.g. GPS position time series. The goal was to simultaneously estimate model and noise parameters, including the spectral index of the spectrum of the noise, which, so far, has been avoided by the geodesy and geophysics communities. With this more comprehensive parameter estimation method (using Bayesian Monte Carlo Markov Chain) uncertainties of estimated parameters are more robust and up to 40% times larger than in previous works. This research ended up with two publications in peer-reviewed journals and a thesis (PhD in Engineering).
    · I have worked as co-responsible of homework supervision of Lectures in Statistics in the Bachelor degree in Civil Engineering, and as supporting professor of Physics Laboratory in the Bachelor degree in Life Sciences.
     
    08/01/2010-08/04/2010 
     Supporting Professor, Universitat Politècnica de Catalunya
    · Responsible for the module applied in mathematics of the first course in the Bachelor degree in Economics.
     
    15/09/2000-15/09/2008
     Teaching Assistant and Researcher, Universitat Autònoma de Barcelona
    · Taught courses at various levels in: general physics, linear algebra, real analysis, computational methods for physics (C language).
    · In 2007 I defended a thesis in Physics which was recognized by the University with an Excellency Award, prize given by the University to fewer than 20% of all theses graded with the highest mark 'Cum Laude'.
    · During this period I gave some talks and presented results of my research in different international conferences and seminars.
     
    EDUCATION
    15/11/2010-21/11/2013
    Doctorate in Engineering, University of Luxembourg
    Thesis: “Analysis and parameter estimation of geophysical time series by means of Monte Carlo Markov Chains”
    The main goal was to develop a Monte Carlo Markov Chains (MCMC) method  that simultaneously estimates all parameters of GPS position time series. 
    With this more comprehensive parameter estimation MCMC method, uncertainties of estimated parameters, e.g. the velocity, are more robust and up to 40% times larger than methods that do not estimate the uncertainty of the esti mated spectral index.
    For shorter time series and time series with low levels of noise it was shown  that the white noise amplitude estimated with the MCMC method was more robust and less biased than with the Maximum Likelihood Estimation method.
    Numerical methods used included: Bayesian statistics for data analysis, Monte Carlo Markov Chain simulation, Linear Algebra, Matrix Inversion, Time Series Analysis.
    Software was developed using: Matlab, C, Shell script and OS Linux.
     
    15/09/2003-30/06/2007
    Doctorate in Physics, Universitat Autònoma de Barcelona
    Thesis: “Constraining interacting cosmological models with observational data”, recognized by the University with an Excellency Award, prize given by the University to fewer than 20% of all theses graded with the highest mark 'Cum Laude'.
    WMAP, SDSS, 2dF and Supernova Ia observational data were used, by means of Bayesian Statistics analysis and Monte Carlo Markov Chains simulations, to constrain the cosmological parameters of theoretical models.
    Numerical methods used included: Runge-Kutta method to solve differential equations, numerical integration methods (Monte Carlo, Romberg), interpolation methods (splines), Bayesian statistics for data analysis, Monte Carlo Markov  chain simulation.
    The main goal was to study the effects of dark matter-dark energy interaction on the cosmological expansion rate, Cosmic Microwave Background perturbations spectrum, Integrated Sachs Wolfe effect, and Large Scale Structure distribution.
    Software was developed using: FORTRAN 77, C, C++, Maple, Shell script, IDL and OS Linux.
