Humberto Cabrera graduated in physics from the ST Kliment Ojhridski University of Sofia, Bulgaria, obtained the master degree in Optics from the ISPJAE University, Havana and the Ph.D degree in Optics from the Venezuelan Institute for Scientific Research. Cabrera was Regular and Senior associate to the ICTP since 2011 till 2017, during this period he was supporting Winter Colleges on Optics taken care of the Hands-on experimental sessions and Director of the Winter College in 2017. In addition, his research activities were combined with the training activities of many visitors from developing countries. He is currently postdoc Researcher at the Abdus Salam International Centre for Theoretical Physics (ICTP) and also is collaborating in FAMU project at Istituto Nazionale di Fisica Nucleare (INFN). Currently, his research activities are directed to the development of photothermal and laser-based methods for thermo-optical characterization of materials, identification and determination of toxic compounds in the environment as well as the investigation of photocatalytic degradation of pollutants in water. Additionally, his research topics covered the implementation of on-line thermal lens detection for electrophoresis techniques applied in separation and detection of nanoparticles and biomolecules using electrophoresis coupled with thermal lens spectrometry. Dr Cabrera has been active in development of solid state laser system used for spectroscopy of muonic hydrogen. He holds 90 publications and two patents with more than 900 citations .
