Degree in Chemical Sciences from the University of Barcelona (1968-1974).
Associate Professor in organic chemistry from the University of Barcelona (1975-1981).
PhD in organic chemistry from the University of Barcelona (1981).
Post Doctoral from IIQAB-CSIC / CNRS (Lyon) (1982-1987).

At present Dr. Caixach is research scientist and head of Laboratory of Mass Spectrometry-Organic Pollutants at the Institute of Environmental Assessment and Water Studies IDAEA-CSIC (Barcelona, Spain).

His scientific focus is the development and application of analytical methodologies based in the most recent mass spectrometry techniques for the study of relevant/emerging & priority organic compounds, both in environmental samples and food matrices. Another field of application is the study of the fate of organic pollutants and degradation products in advanced water treatment processes: wastewater, desalination, drinking and reclaimed water. We have specialized in the families of Perfluoroalkyl substances (PFAs), aquatic toxins: microcystins and marine toxins (PLTX, Ciguatoxins...).

The main research activity is the development and application of HRMS through the most powerful analysers (FT-ICR, FT-Orbitrap, and TOF) in matrices type NOM (natural organic matter), lipidomic, in collaboration with national and foreign groups. Nowadays, their research group is approaching different challenges related with the concern of identification of “know-unknowns” compounds.

Regarding to R & D, the main activity is the development of the analytical methodologies for organic contaminants included in the Water Framework Directive, commissioned by the Ministry of the Environment / Spanish General Direction of Water, and the study and evolution of these contaminants in the water treatment processes for the main European and national water companies.

Dr. Josep Caixach is reviewer of the most common analytical and environmental chemistry journals and member of: the American and Spanish Societies of Mass Spectrometry; the Spanish Society of Chromatography and Related Techniques; the Consolidated Research Group (GRC) on Toxic Microalgae and Associated Toxins recognized by the Generalitat de Catalunya (2017-2019); and the Iberian Networks of Cyanotoxin and Toxic Algae and Biotoxins.
