Teaching Interests

Professor Howarth is the coordinator for the Laboratory Animal Science course that was introduced in the B Sc (Animal Science) program in 2007.  Professor Howarth is a work experience student coordinator at the University and at the Women's and Children's Hospital. He also supervises groups of 3rd year Physiology students in research projects annually. Professor Howarth currently has five PhD students, one M Phil student and four Honours students in his laboratory.

Research Interests

Professor Howarth's research focuses on understanding the mechanisms by which newly-identified bioactive agents act in the intestine. These bioactive agents include probiotics, probiotic-sourced bioactives, prebiotics, synbiotics and bioactive extracts of plant, animal and marine origin. Dr Howarth has developed a wide range of animal models of gastrointestinal disease over a 20-year period. These include models of gastric ulceration, NSAID-enteropathy, chemotherapy-induced mucositis, radiation enteritis, the inflammatory bowel diseases Crohn's disease and ulcerative colitis, and colon cancer. He has utilized these models to demonstrate therapeutic applications for a number of growth factors (eg IGF-I, the subject of Professor Howarth's PhD studies) and bioactive formulations including a whey-derived growth factor extract that is currently undergoing clinical trial for the treatment of oral mucositis. Although Professor Howarth has been an Affiliate title-holder in the University for many years, he joined the University of Adelaide as an Associate Professor in the Discipline of Agricultural and Animal Science in early 2006. Professor Howarth is supported by a Senior Research Fellowship from the Cancer Council of Australia. Specific areas of research in the Howarth laboratory include:

"       Application of probiotics and probiotic-sourced factors for prevention of bowel inflammation
"       The role of medium-chain fatty acids in the development of colon cancer 
"       Effects of chemotherapy agents on intestinal stem cell expression
"       Effects of new bioactive agents on intestinal stem cell expression
"       Determining potential efficacy of prebiotics such as FOS/GOS in models of intestinal mucositis and inflammatory bowel disease 
"       Determining potential efficacy of newly-identified bioactives including dipeptidyl peptidase inhibitors, marine and land mollusc-sourced extracts, wine-sourced procyanidins and herbal extracts for treatment of intestinal mucositis, inflammatory bowel disease and other bowel disorders
"       Gut function analyses of congenital disorders such as  mucopolysaccharidosis
"       Determining gene expression profiles in the intestine
"       Nutraceutical modification of animal diets to improve growth performance and animal welfare
