C. M. Nunes graduated in Chemistry from the University of Coimbra in 2004, obtained his MSc degree in Organic Chemistry in 2007 and PhD degree in Molecular Spectroscopy in 2012. He worked as postdoctoral researcher at the Laboratory for Molecular Cryospectroscopy and Biospectroscopy (LMCB) of the University of Coimbra from 2013 to 2018. Besides a short-period as a Postdoc at the Department of Chemistry of the University of Fribourg (Switzerland), he also spent several months working as visiting researcher at the Organometallic Chemistry Institute of the University of Oviedo (Spain), at the Department of Chemistry of the University of Wisconsin–Madison (USA), and at the Institute of Organic Chemistry of the Justus-Liebig University Giessen (Germany). In 2019, he started his independent research career at the CQC - University of Coimbra as an Auxiliary Researcher funded by the CEEC program of the Portuguese Science Foundation. C. M. Nunes researcher program is focused on vibrational excitation chemistry and quantum mechanical tunneling. He currently coordinates a small research team hosted in the group of Prof. Rui Fausto and is principal investigator of the aCTIVE project (FCT/COMPETE 2020) and co-principal investigator of the QUANTUN project (FCT).
