Xenobiotic metabolism and toxicology

Research is focused on the role of xenobiotic metabolism in in drug action and toxicity: qualitative and quantitative analysis of biotransformation pathways, and their between subject and inter-species variability have been explored in the development of in vitro and in vivo models to assess human drug metabolism and toxicity. In particular, the balance between protective and detrimental pathways of drug metabolism has been a focus for more than 25 years. Several methods to alter this balance have been investigated: chemical modification, biochemical inhibition and altered expression of the enzymes involved in the bioactivation or detoxification of foreign compounds. Expertise involves the development of analytical techniques that allow accurate and precise determination of drug/metabolite concentrations in biological tissues for determination of pharmacokinetic parameters. This is applied to drugs in clinical use, as well as compounds under development for therapeutic use or, for example, to screen for their potential as species-selective rodenticides.

2010- New Zealand 3Rs Champion. This is a network of key opinion makers developed by MAF (now MPI) to act as contacts for information sharing as part of the New Zealand Three Rs Programme strategic plan to promote the understanding, application and development of the Three Rs in New Zealand 

May 2013-January 2014 Member of Interim Psychoactive Substances Expert Advisory Committee providing toxicological and clinical pharmacology expertise. This committee, established by the Ministry of Health as a consequence of the Psychoactive Substances Bill, provides advice to the Ministry on a robust testing regime to ensure that psychoactive substances used for a psychoactive effect will pose no more than a low risk of harm to the individuals using them. This includes the need for pre-clinical toxicology data (e.g. acute toxicity, repeat dose toxicity, genotoxicity, developmental toxicity, toxicokinetics and pharmacokinetics) as well as data from human clinical trials to determine the maximum approved human dose for the product, and to determine common adverse effects.

February 2014- Member of the Psychoactive Substances Expert Advisory Committee. The role of the committee is to evaluate, based on the results of trials, whether psychoactive products should be approved for use by individual; to advise the Authority on whether a psychoactive product should or should not be approved for use by individuals; to increase public awareness of PSEAC’s work in relation to psychoactive substances; and to contribute to the Authority’s work programme on the new psychoactive substances regime.  In carrying out its functions, PSEAC will take account of government policy on health and disability and psychoactive products; be cognisant of the importance of minimising costs and spending taxpayer funding wisely; and engage with other experts, as necessary, if the PSEAC lacks the expertise needed for particular advice.https://www.health.govt.nz/about-ministry/leadership-ministry/expert-groups/psychoactive-substances-expert-advisory-committee-pseac

November 2013- Member of the National Animal Ethics Advisory Committee (nominated by the Health Research Council of New Zealand). This committee has been established under the Animal Welfare Act to provide independent advice to the Minister for Primary Industries about: ethical and animal welfare issues relating to the use of animals in research, testing and teaching; recommendations on the restrictions of use of non-human hominids; advice to Animal Ethics Committees; the development and review of codes of ethical conduct. A full list of NAEAC’s functions can be found under section 63 of the Animal Welfare Act 1999. In addition, NAEAC produces an annual report and these can be found at: https://www.mpi.govt.nz/protection-and-response/animal-welfare/national-animal-ethics-advisory-committee/

June 2019- Member of the Medicines Assessment Advisory Committee.The Medicines Assessment Advisory Committee (MAAC) is a technical advisory committee established under section 8 of the Medicines Act 1981 to advise the Minister of Health on the risk-benefit profile of new medicines. https://www.medsafe.govt.nz/regulatory/MAAC.asp
