Bruno Merín’s CV

Curriculum Vitae


Announcement Image

I finished my Physics degree in the Universidad Autónoma de Madrid on June 1998, with a specialization in Theoretical Physics. After that, I joined LAEFF (“Laboratorio de Astrofisica Espacial y Fisica Fundamental”) of INTA, the Spanish National Technical Institute for Aerospace, where I did my Master and Ph.D. Thesis under the supervision of Prof. Benjamin Montesinos and Prof. Carlos Eiroa.

The subject of my Ph.D. thesis was to study the evolution of the circumstellar disks around intermediate mass stars, the so-called Herbig Ae/Be stars,…

Harvard-Smithsonian Center for Astrosphysics

Announcement Image

I defended my Ph.D. Thesis at the Universidad Autónoma de Madrid on March 2004.

During my Ph.D. Thesis I was lucky enough to travel to Morelia, Mexico, to have a collaboration with Dr. Paola D’Alessio, a world-known expert in the physics of protoplanetary disks and author of one of the best numerical models to physically reproduce the observations of such type of objects. After that experience, I was then invited by Profs. Nuria Calvet and Lee Hartman to the Harvard-Smithsonian Center for Astrophysics, in Cambridge, Massachusetts (USA)…

Fundación Ramón Areces

Announcement Image

I was awarded my first postdoctoral fellowship by the Fundación Ramón Areces, in Spain, to come to the Leiden Observatory, in the Netherlands, to work with Prof. Ewine F. van Dishoeck (Leiden Sterrewacht, Leiden University) in the analysis of the Spitzer data from the large “Cores 2 Disks” Legacy program, led by Prof. Neal J. Evans, from the University of Texas at Austin (USA).

During this period of time, I had the chance to learn about the data analysis of the images and spectra from the Spitzer Space Telescope and to observe at several…

Leiden observatory

Announcement Image

After two years at Leiden observatory, I obtained an ESA Research Fellowship to work with Dr. Timo Prusti at the Research and Scientific Support Department of ESTEC, from the European Space Agency, at Noordwijk, in the Netherlands, and continued to work closely with the Leiden and c2d team members, given the proximity of ESTEC and Leiden.

During that time, I also got involved in the testing team of the Mid Infrared Instrument MIRI for the James Webb Space Telescope, which took place at the Rutherford Appleton Laboratory, near Oxford in…

Herschel Science Center

Announcement Image

In October 2008 I joined the Herschel Science Centre, the science operations center of the Herschel Space Observatory, located at the European Space Astronomy Centre (ESAC) of the European Space Agency, near Madrid, in Spain. Here I was Data Processing scientist and chair of the Data Processing Users’ Group, a body that coordinated the user input and fed it back into the development plan for the Herschel data reduction software, called HIPE.

ESAC Science Data Center (ESDC)

Announcement Image

In July 2015 I became Astronomy Archives Science Lead at the ESAC Science Data Centre.

My work in this group was to try to maximize the scientific use of ESA’s Astronomy science data archives and to contribute to the creation of new modern ways of exploiting that precious space science data. Back then I was also the Product Owner of the ESASky portal.

Publications and publication statistics

I am coauthor of 103 refereed papers, which have been cited in another 4,561 papers. My H-factor is 46 and I am coauthor of one of the top-10 most cited papers in Astronomy in 2010, the Spitzer “cores to disks” c2d summary paper by Evans et al. 2009.

Referee and committee work

Outreach / Media

Since I joined ESA, I have participated in a numerous outreach initiatives, aimed at sharing the fascination of doing astronomy and space science nowadays with the general public. You can find me on Twitter and on Facebook.

Here you have a very incomplete list of outreach events I have participated to recently. Some of hese collaborations have been done in Spanish and amount to two articles in the top-audience general newspaper “El País”:

And some participations in Radio programs, both at the Radio Círculo and at Radio Exterior from Radio Nacional de España:

The study of disk evolution
The study of disk evolution
De-noising HST images with U-Nets
Machine learning on archives
Finding asteroid trails in HST data with AutoML
Machine learning on archives
The exoplanet revolution
The exoplanet revolution

Research group

There is a good number of scientists working at ESAC who study star- and planet formation. The environment favors the interaction with planetary scientists involved in ESA’s mission to planets and other bodies of the Solar System and with Data Scientists interested in applying modern Machine Learning techniques to the wealth of high quality scientific data in our Science Data Archives. If you fit any of those groups and are interested to work with us, do consider applying!!
