Some quotes and statements that influence my life and work:


"I am astonished when I look back on what has been accomplished in the field of solar neutrino research over the past four decades. Working together, an international community of thousands of physicists, chemists, astronomers, and engineers has shown that counting radioactive atoms in a swimming pool full of cleaning fluid in a deep mine on Earth can tell us important things about the center of the Sun and about the properties of exotic fundamental particles called neutrinos. If I had not lived through the solar neutrino saga, I would not have believed it was possible."

J. N. Bahcall  in “Solving the Mystery of the Missing Neutrinos” - www.nobelprize.org


"The increasing velocity of the paper number is higher than the speed of light, but there is nothing to worry about for there is no violation of any physical law, because these papers carry no information"

S. Chandrasekhar


"La science, mon garçon, est faite d'erreurs, mais d'erreurs qu'il est bon de commetre, car elles mènent peu à peu à la vérité"

Professor Lidenbrock to Axel in Jules Verne's Voyage au centre de la terre


"In the mystery business, the truth may be out there, but the key to discovery is in never really finding it"

“Political language... is designed to make lies sound truthful and murder respectable, and to give an appearance of solidity to pure wind.”

George Orwell


“We all live in the midst of human imperfections, including our own. We each carry on with our own best effort and accept that as the best anyone can do.”

Eugene N. Parker - Personal communication


“What the use of P [the significance level] implies, therefore, is that a hypothesis that may be true may be rejected because it has not predicted observable results that have not occurred. This seems a remarkable procedure.”

Sir Harold Jeffreys - Theory of Probability (1939), 316


“Far better an approximate answer to the right question, which is often vague, than an exact answer to the wrong question, which can always be made precise.”

John W. Tukey


“If your experiment needs statistics you ought to have done a better experiment”

Lord Rutherford


“Seeing is not a direct apprehension of reality, as we often like to pretend. Quite the contrary: seeing is inference from incomplete information.”

E.T. Jaynes, 2003


“To consult the statistician after an experiment is finished is often merely to ask him to conduct a post mortem examination. He can perhaps say what the experiment died of.”

  1. R.A. Fisher


“I wasn’t doing my job. I wasn’t using my mind to produce the external evidence of my inner state”

George Carlin in “Last Words”


“In science we never know any theory of nature is absolutely true because our reasoning is based on incomplete information. Our conclusions are at best probabilities.”

Phil Gregory in “Bayesian Astrophysics”



I am an astrophysicist with interests in Magneto-hydrodynamics (the union of fluid dynamics and electromagnetism to study the dynamics of magnetized plasmas) and Bayesian Analysis (the extension of ordinary logic to probabilistic inference). I obtained a PhD in Physics at Universitat de les Illes Balears (Spain, 2003) with a thesis on MHD waves in the solar atmosphere. I have carried out research in Spain, Belgium, and Japan. Currently, I have a tenure-track position at Instituto de Astrofisica de Canarias in Tenerife, Spain.

My research is focused on the interpretation and modeling of wave activity in the solar atmosphere, the design of inversion and model comparison tools for remote sensing of the physical conditions and the dynamics of solar atmospheric plasmas, and the study of wave based plasma heating mechanisms. My aim is to further develop the fields of seismology and wave heating of the solar atmosphere in combination with observations from space solar missions.
