We are organising and hosting the 2017 Australasian Chronobiology Society Meeting 

23rd -24th October at The Venue,Onetangi, Waiheke Island, Auckland. 

We have two emminent international chronobiologists giving keynote addresses: Professor Russell Foster, Oxford University and Professor Steve Kay, University of Southern California.

My research interest is in chronobiology and the interplay between anaesthesia and the circadian clock.  

Together with my colleagues, Dr Cheeseman in particular,  I have developed a "Chronobiology Research Group" in the Department of Anaesthesiology at the Faculty of Medical and Health Sciences.

Our basic research is focussed on the investigation of the control of circadian rhythms and the similarities between sleep and anaesthesia using invertebrate and vertebrate models. Our applied research focuses on human circadian rhythms and sleep in the hospital environment, and the influence time of day has on drug action.  The findings from our basic research underpin and direct our applied work in-hospital.

I have 40 publications in international peer-reviewed journals and an  h-index of 15.  Our work has been supported by a number of research grants including the RSNZ's Marsden Fund, The Health Research Council of New Zealand and the Office of Naval Research (USA).  

We have active and productive collaborative links internationally with Professor Randolf Menzel at the Free University of Berlin and Professor Shin Yamazaki at the University of Texas, SouthWestern Medical Center in Dallas.  

We have interdisciplinary collaborations within the University of Auckland with researchers in the School of Medicine the Faculty of Medical and Health Sciences and in the Faculty of Science

I have supervised a  total of 26 post-graduate research students (PhD, masters and honours students) and 16 summer students. I am currently main supervisor of two PhD students (Nicola Ludin and Alma Orst-Sebastian) and co-supervise two PhD students (Jia Zhao and Dongni Li) and one masters student (Joshua Paul).

Prior to my appointment at the University of Auckland as lecturer in 2005 I was a research fellow at Green Lane Hospital, before that I was a post-doctoral fellow at the Centre for Chronobiology University of Surrey, U.K. working with Professor Jospephine Arendt and her group.

Committees/Professional groups/Services

I am deputy HOD and graduate advisor.  I represented our department on the SOM research committee from its formation until 2015.  I sat on the FMHS staffing committee, and senate and currently sit on the Faculty of Science staffing committee. I sit on review panels (FRDF, mock Marsden, internal PBRF).   I have been involved in public outreach (LENscience lectures; TVNZ7 Ever Wondered; TV/radio/newspaper interviews, RSNZ “ten by ten series”). I have served on the Australasian Sleep Association Education Committee, reviewed grants for Wellcome, BBSRC(UK), MRC(UK) HRC, WMRF and the Czech Science Foundation and reviewed manuscripts for 12  journals.  I have been an invited speaker at 25 international and national clinical and scientific meetings
