He is currently an adjunct professor at the Polytechnic Institute of Guarda (Guarda, Portugal), and he is an invited assistant professor at the Faculty of Health Sciences of the University of Beira Interior (Covilhã, Portugal). He is also a collaborator of the CPIRN-UDI-IPG, Center for Potential and Innovation of Natural Resources, Research Unit for Inland Development, Polytechnic Institute of Guarda (Guarda, Portugal), and a member of the CICS-UBI, Health Sciences Research Centre of the University of Beira Interior (Covilhã; Portugal). Currently, his main focus of research is the intranasal drug delivery of compounds in which it is essential, the development of the (nano)formulation, as well as its pharmaceutical characterization and subsequent pre-clinical evaluation (in rodents) considering intranasal administration and comparison with the oral and/or intravenous route. Another core area is at the level of chromatographic analysis through the development of validated analytical methods that are an essential tool for the quantification of drugs in different matrices, whether biological matrices such as plasma or brain, or pharmaceutical formulations.
