Summary
Protection from infections relies on different types of immune cells. While some of these cells are found in the blood, others reside in peripheral tissues such as the skin. We will analyse the function of these peripheral immune cells to understand how they work to fight off infections. We will also investigate how so-called memory cells that permanently reside in peripheral tissues can protect from re-infection with similar bacteria or viruses.
Subset Determination Of Tissue-Resident T Cell Memory

Summary
Immunity relies on white blood cells called T cells that circulate around the body and which are also found permanently lodged at body surfaces. It is non-circulating T cells that are the most important in protecting against infection. In this application we propose to show that only a subset of T cells can form the resident population and to identify the molecules that determine T cell residency. This information can then be used for the efficient construction of disease preventing vaccines.

Summary
I am an internationally recognized expert in the field of lymphocyte biology. My work has shed light on antibody production, T cell responses and immune pathology. Specifically, I have identified molecular regulators that link antigen recognition, lymphocyte population expansion, cellular metabolism and effector function. My ongoing work focusses on the development and function of several critically important cell types, including tissue resident lymphocytes and regulatory T cells.
A Randomised Control Trial Of A Group-Based Intervention For Substance Abuse In Psychosis.

Summary
The use of alcohol and illicit substances is common amongst people with psychotic illnesses, and is associated with a poor outcome in terms of severity of symptoms, treatment adherence, work-studies, family cohesion, aggression and quality of life. All this adds significantly to the cost of mental health services and society more broadly. The proposed study aims to refine, pilot, and rigorously evaluate a group-based intervention that targets substance use in such individuals at different stages ....The use of alcohol and illicit substances is common amongst people with psychotic illnesses, and is associated with a poor outcome in terms of severity of symptoms, treatment adherence, work-studies, family cohesion, aggression and quality of life. All this adds significantly to the cost of mental health services and society more broadly. The proposed study aims to refine, pilot, and rigorously evaluate a group-based intervention that targets substance use in such individuals at different stages of their illness, and within a number of different treatment settings. The intervention will be informed by an enhanced understanding of the motivations for substance use in people with psychotic illnesses The specific aims are to: Refine, implement and evaluate, using a controlled experimental design, a novel group-based intervention for reducing substance abuse comorbidity in people with psychotic disorders; Determine reasons for substance use by these individuals, to inform the intervention procedures; Pilot the intervention in a series of different treatment settings, including early episode and rehabilitation programs, and non-government organisations dealing with people with psychotic disorders, to ensure generalisability, adaptability, and acceptability; Augment case managers' knowledge and skills in dealing with comorbid drug and alcohol use Enhance detection, motivation to change, ongoing monitoring and relapse prevention of substance misuse in clients with psychotic disorders. It will also be possible, once the treatment intervention is finalised and evaluated, to expand its use to patients with non-psychotic mental illnesses.Read moreRead less
The body’s surfaces are continually under threat from microbes that may cause debilitating disease. Our ability to control such infections relies on our immune system, consisting of different cell types with specialised functions. We will study frontline immune cells that populate barrier tissues such as skin and mucosa where they provide enhanced local protection by responding vigorously on infection. Our studies will guide the development of future therapies harnessing our immune system.
Randomised Control Trial Of Three Treatments For Adolescent Stutterers

Summary
Effective communication is an essential of everyday life, and stuttering impairs this function. Those who stutter may find effective communication impossible, and severe cases may be rendered almost mute. Clinically significant anxiety figures prominently in the disorder with almost half of those seeking treatment warranting a comorbid diagnosis of social phobia. The adolescent years are generally regarded as a difficult time of life, at which time the potential effects of disfigured speech can ....Effective communication is an essential of everyday life, and stuttering impairs this function. Those who stutter may find effective communication impossible, and severe cases may be rendered almost mute. Clinically significant anxiety figures prominently in the disorder with almost half of those seeking treatment warranting a comorbid diagnosis of social phobia. The adolescent years are generally regarded as a difficult time of life, at which time the potential effects of disfigured speech can be devastating. There has been much research and development of treatments for children and adults who stutter, proven effective treatments are available for those age groups. However, little is known about how to treat adolescents who stutter, and there has been little research and development to find the best treatment-s for this age group. The present proposal is for a randomised, controlled trial of three treatments that have been shown recently to have promise as treatment methods for this age group of patients. The trial will compare (1) a treatment that involves biofeedback muscle activity during speech, (2) a treatment that involves biofeedback of voice box activity during speech, and (3) a variant of a standard treatment that trains the speaker in a new speech pattern. The control group will receive no treatment. The trial extends for a period of 12 months after the subjects are randomly allocated to a treatment group or a control group. The subjects' speech will be assessed in a variety of situations in the clinic and during everyday life. The prime outcome measure will be percentage of syllables stuttered, and secondary measures will be the time required for treatment and how natural the patients sound after treatment. At the conclusion of the trial, the subjects in the control group will be given the treatment that was shown to be most effective.Read moreRead less
Evaluating Flexible Delivery In The Get Healthy Information And Coaching Service–A Partnership Project Between The NSW Ministry Of Health, Healthways, Healthdirect, The University Of Sydney And The University Of Queensland

Summary
High rates of participant drop-out are a problem in many health promotion programs. This is the case for the Get Healthy Service (GHS), a telephone health coaching service to assist adults to be active, eat healthy and lose weight. This Partnership Project aims to improve GHS retention rates without compromising the effectiveness of the GHS. Retention strategies will be evaluated in a randomised controlled trial. Results will inform changes to service delivery.
Regulation Of Metabolic Dysfunction And Exhaustion Of Virus-specific T Cells During Chronic Infection

Summary
T cells control infections and cancer cells. During chronic infection or tumor development, however, loss of function of T cells prevents efficient clearing of pathogens or cancer cells, a phenomenon termed T cell ‘exhaustion’. We have found that the regulator protein IRF4 controls cellular nutrient usage, growth and function of T cells and that very amounts of IRF4 occur in T cells during chronic infection. We propose to examine the precise role of IRF4 in chronically stimulated T cells.
