In the last 10 years I have collaborated in the execution of more than 30 phase I-II clinical trials, most of them enrolling healthy volunteers and assessing concentrations and subjective effects of illegal drugs, alcohol or medicines affecting the central nervous system. As a clinical pharmacologist I have broad background in ethics and research methodology in human beings. I have experience in the design and execution of clinical trials and meta-analysis in the field of addiction and psychopharmacology.
