Genetics of mental health (new research)

We are using the genetic model organism, C. elegans, do investigate the genetic basis of both normal and disordered behaviour. Our current interests are identifying the genes responsible for anxiety and depression as well as the genes for eating disoders and addiction. Using C. elegans as a model organism will also allow us to study gene function as it relates to behaviour.

Molecular mechanisms of phosphine resistance (other research)

Genetic mapping of oxidative stress resistance genes. The fumigant phosphine disrupts oxidative metabolism, resulting in the production of reactive oxygen intermediates. This causes the premature ageing and death of targeted pests. Insect pests of stored grain in Australia now exhibit resistance to phosphine at levels more than 200 times the normal lethal dose.

We have genetically mappedf and identified the genes responsible for phosphine resistance in tall major insect pests of stored grain. We are using a systems biology approach in the model organism C. elegans to understand the molecular basis of phosphine action. Our genetic studies have recently shown that resistance to phosphine is associated with an extension of lifespan

Dr Daniel Sullivan is a Clinical Psychologist and Adjunct Lecturer in the Child Health Research Centre, The University of Queensland. In his clinical role, Dr Sullivan leads a program of research to design Australia's first psychology extended scope of practice model of care for limited pharmacotherapy management, with an emphasis on deprescribing hypnotic medicines in the public sector sleep psychology setting (ExPEDiTe Sleep project). As a member of the Let’s Yarn about Sleep group at the University of the Sunshine Coast, Dr Sullivan is working to improve sleep health equity for First Nations Australians through community co-designed, culturally responsive sleep programs which harmonise sleep science with Indigenous Australian perspectives and knowledges about sleep.

Dr Sullivan’s research and clinical expertise is in the behavioural aspects of sleep; he is an Editor of the journal Research Directions: Sleep Psychology (Cambridge University Press) and is board certified by the US-based Board of Behavioral Sleep Medicine. Dr Sullivan completed postgraduate training in sleep at the University of Sydney (MSc), and his PhD in Clinical Psychology at Griffith University, where his doctoral research examined psychological factors involved in sleep-related headaches.

Tim is a clinical pharmacist and conjoint lecturer working at the School of Pharmacy and the Princess Alexandra Hospital. He graduated from the Bachelor of Pharmacy at the University of Queensland in 2014. After working in mental health at the Princess Alexandra Hospital, he become interested in schizophrenia and psychopharmacology. He began his PhD with the School of Clinical Medicine in 2020 and his research interests include clozapine, treatment refractory schizophrenia, and the safe use of antipsychotic medicines. He is the team leader of mental health pharmacy at the Princess Alexandra Hospital. Tim teaches into the Bachelor of Pharmacy and the Masters of Clinical Pharmacy programs at the University of Queensland, and supervises research project placements.
