JC studied Physics in Granada, Spain. He took his PhD in atmospheric gas phase halogen photochemistry, kinetics and spectroscopy with Prof. John P. Burrows at the Institute for Environmental Physics and Remote Sensing of the University of Bremen (2002-2006). His external examiner was Prof. Richard Wayne. After a brief post-doc in Bremen, in 2007 he was hired by Prof. John M. C. Plane to carry out laboratory research on photochemistry and gas-to-particle conversion processes of mesospheric and tropospheric relevance at the School of Chemistry of the University of Leeds. In 2009 he moved to Toledo, Spain, where he worked with Alfonso Saiz-Lopez at the Laboratory for Atmospheric and Climate Science of the Spanish Research Council (CSIC), now the AC2 department of the Rocasolano Institute of Physical Chemistry. At Toledo, JC’s research focused on the design, construction, development and field deployment of spectroscopy-based instruments for in situ measurements of precursor, active and reservoir halogen species, with implications for tropospheric ozone destruction and new particle formation. In 2012 he moved back to Leeds to work in Prof. Plane’s ERC-AdG project CODITA – Cosmic Dust in the Terrestrial Atmosphere. During this 5-year project, JC expanded his laboratory expertise on laser spectroscopy and mass spectrometry and performed spectroscopic, chemical kinetics and phase change experiments relevant for the disintegration of meteoroids in planetary atmospheres and its impacts on atmospheric aerosol. In 2017 he was awarded a Ramon y Cajal tenure-track fellowship by the Spanish Ministry of Economy and Competitiveness and moved to Granada (Spain) to join the Institute of Astrophysics of Andalucía (CSIC), where he is currently working on laboratory and remote spectro-photo-polarimetric characterisation of zodiacal, cometary and asteroidal dust.
