Research Programs




I have over 10 years experience as a European registered toxicologist, with a focus on research in neurotoxicity and clinical toxicology. What I like most, is working on research projects that have an impact on society.

My research focuses primarily on poisonings with psychoactive substances via observational human studies. In clinical toxicology, such data are often the sole source of information. Also, such data is valuable to protect public health and develop policy strategies.

Specialities: research, clinical toxicology, neurotoxicology, risk assessment, drugs (MDMA, novel psychoactive substances (NPS), nitrous oxide)

Skills: analytical, project coordination, perseverance, well-organized and structured.
