Rate My Professor Javier Trujillo Bueno

Javier Trujillo Bueno is a Research Professor of the Spanish Higher Council for Scientific Research (CSIC) and Senior Scientist at the Instituto de Astrofísica de Canarias (IAC), where he has worked since 1990. He is affiliated with the Department of Astrophysics at the Universidad de La Laguna, serving as Professor in the Master of Astrophysics program, teaching courses on Magnetism and Astrophysical Spectropolarimetry. He earned his PhD in Physics from the University of Göttingen, Germany, in 1988, a Master's in Physics from the Department of Quantum Optics at the University of Zaragoza in 1982, and a Bachelor's degree in Physics from the University of Zaragoza in 1981. His career encompasses a postdoctoral position funded by the Spanish Ministry of Science (1988–1990), Senior Scientist at CSIC (1990–2004), Senior Researcher (2004–2008), and Research Professor since 2008. Notable appointments include Gauss Professor at the University of Göttingen awarded by its Academy of Sciences in 2006, Visiting Scientist at the Arcetri Astrophysical Observatory (1992–1994), and Affiliate Scientist at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, since 2016.

Trujillo Bueno's research centers on solar physics, with specializations in solar magnetism, theoretical and observational spectropolarimetry, quantum theory of light polarization, radiative transfer in magnetized plasmas, and numerical simulations. He has developed innovative methods using atomic polarization to diagnose magnetism in the solar atmosphere, resulting in landmark publications such as "Selective Absorption Processes and the Origin of Puzzling Spectral Line Polarization from the Sun" (Nature, 2002), "A Substantial Amount of Hidden Magnetic Energy in the Quiet Sun" (Nature, 2004), "Mapping Solar Magnetic Fields from the Photosphere to the Base of the Corona" (Science Advances, 2021), and "Magnetic Field Diagnostics in the Solar Upper Atmosphere" (Annual Review of Astronomy & Astrophysics, 2022). As Principal Investigator of the ERC Advanced Grant POLMAG (2017–2023)—the first awarded to a Spanish scientist in the Science of the Universe—and Co-Principal Investigator of NASA's CLASP sounding rocket experiments (2011–present), he received two NASA Group Achievement Awards (2020 and 2022). He has supervised over a dozen PhD theses, edited conference proceedings, and served on committees including the Scientific Advisory Committee of the European Solar Telescope (since 2017) and the MIRADAS instrument working group for the Gran Telescopio Canarias (since 2010).
