His research has focussed on the role of metabolism in toxicology and the development of in vitro and in vivo models to assess toxicity. In the field of addiction research, he has examined the pharmacokinetics of 'party-pill' constituents BZP & TFMPP and their potential for drug-drug intreactions. He is jointly supervising a PhD student's research investigating the pharmacokinetics of cytisine, a natural smoking cessation product and attempting to relate pharmacokinetics to the pharmacodynamic effects of this drug.
