Born in Llanes(Asturias, Spain)
in 1955 and grew up in Cabezón de la Sal (Cantabria, Spain). Obtained
a Ph.D. in Physics at the University of Cantabria in 1984 and was awarded the
Premio Extraordinario de Doctorado in 1985. A DGICYT Senior Postdoctoral Fellowship initiated collaboration in High Pressure Research and High Resolution
Optical Spectroscopy at the University of Bern in Switzerland
(1989 and 1991). He was a visiting scientist in the Solid State Group at King's College London (1995-1996) to investigate impurity defects in Silicon using FT spectroscopy. User scientist in Large
facilities (ILL and ESRF in Grenoble, and LURE and LLB in Orsay) and participated in different research projects.
He has supervised several Thesis
and a Final year projects in the field of Optical Properties of materials and
High Pressure research. He collaborates with different research groups and
leads the High Pressure & Spectroscopy Group. Since 1998 is involved in the
European High Pressure Research Group (EHPRG)
as Committee Member (1998-2000), Secretary (2000-2003) and Chairman
(2003-2006). Affiliate Member of the Physics Department at Colorado State
University since 2005. Head of the Earth Science
and Condensed Matter Physics (DCITIMAC) of the University
of Cantabria (2004-08).
Specialities and research
His main research field is the optical
properties of materials, searching for correlations with their structural
and magnetic properties. Preferred interest is focused
in Jahn-Teller systems, impurities, defects and localised centers
formed in insulators and semiconductors. Expertise in High Resolution Optical Spectroscopy and High Pressure techniques.
Present reasearch topics:
Optical properties of materials under pressure. High pressure research. Microspectrometers for DAC.
Charge Transfer and Crystal Field spectroscopy of transition metal ions. Thermochromic
and piezochromic properties.
Correlation studies between optical, magnetic and structural properties
in Jahn-Teller systems of Cu(II),
Ti(III), Ni(III), Co(III) and Mn(III).
Photoluminescence studies of materials containing Mn(II) and Cr(III). Local structure characterisation from EXAFS and Optical
Study of defect centers in Silicon through
optical spectroscopy. Center formation and passivation by Li.
