Prof. Juan Carlos Colmenares-Quintero graduated from Warsaw University of Technology (Chem. Eng. 1995) and obtained his M.Sc. (1997) in catalysis for organic technology and Ph.D. (2004) in chemical and material sciences from the same university, a scientific degree of habilitation (D.Sc. 2015) from the Institute of Physical Chemistry of the Polish Academy of Sciences in Poland, and in 2023 Full Professor in Chemical Sciences given by the Council of Excellence in Poland/Office of the President of Poland. His interests range from materials science, nanotechnology, and heterogeneous catalysis to biomass/CO2 valorization, solar chemicals, sonication, photocatalysis, and water/air purification. After obtaining his Ph.D., he worked at the University of Córdoba, Spain (2005–2006) in Prof. Marinas’ group as a postdoctoral fellow, and at the University of Southern California, Los Angeles (USA) (2006–2009) in Prof. G. A. Olah’s (Nobel Prize in Chemistry) group as a postdoctoral associate. He is a Marie Skłodowska-Curie fellow. He serves as an expert evaluator for many important scientific journals/institutions and chemical companies (Colombia, USA, Poland, Spain, China), and as a member of the editorial advisory board for Scientific Reports and Molecules (Photochemistry Section) journals. He has coauthored more than 150 works published in international scientific journals and books and filed seven patent applications. He is working as a full professor at the Polish Academy of Sciences.
