Research Experience


MCL, The Open University, Milton Keynes, UK — 2016

Multi photon ionisation and electron impact on biological relevant molecules and molecular clusters. Stark effect on molecules in strong electric field.



LCAM, CEFITEC, FCT/UNL, Monte da Caparica, Portugal — 2014 to Present

Study of electron induced damage in aeronomic and biological relevant molecules by electron transfer processes in atom-molecule collisions.



MSc Thesis, FCT/UNL, Monte da Caparica, Portugal — 2014

Study of properties such as transmission, angular dispersion and energy dependence of an alkali beam with SIMION™. Designing and assembling of an energy analyser in a molecular cross beam apparatus, and alkali beam’s current density optimisation. Beam energy profile characterisation.


Other Activities

My MSc thesis work comes integrated into the research work carried out at the Atomic and Molecular Collisions Laboratory, LCAM, of CEFITEC, located in FCT/UNL which aroused another projects to be implemented in the future such as the assembling of a hemispherical energy analyser with a high resolution. That will accurately determine the potassium cations energy loss in electron transfer processes on aeronomic and biological relevant molecules in order to understand the effects of radiation induce damage in the biomolecular environment at the molecular level, by studying negative ion yields on electron transfer processes to DNA nucleobases, RNA and amino acids in atommolecule collisions. I am currently working at the Open University studying biomolecular clusters by multi photon ionization and electron impact. The study of biomolecular clusters can enhance our understanding of radiation effects on the nanoscale with applications in medicine, nanotechnology, atmospheric physics, and astrochemistry.
