Isabelle Straumann obtained her Master of Science degree in Pharmacy from the University of Basel in 2019. During her Master’s, she worked in the Psychopharmacology research lab of Prof. Matthias Liechti at the University Hospital Basel where she investigated how various genotypes affect the pharmacokinetics and pharmacodynamics of LSD in healthy test volunteers.

In 2020, she started her PhD under the supervision of Professor Matthias Liechti where she investigates different entactogens as well as the simultaneous use of MDMA and LSD. As part of her research, she has accompanied over 170 substance sessions with various substances (MDMA, MDA, LSD, DMT, psilocybin, and mescaline) in healthy test subjects. Her primary research interests lie in the pharmacology of psychoactive substances, specifically entactogens and psychedelics, and their effect on oxytocin levels.
