Dr Tiffani Howell is a Research Fellow in the School of Psychology and Public Health at La Trobe University. She is currently co-leading a trial, funded by the Department of Veterans’ Affairs, to understand the effectiveness of assistance dogs as an adjunct to treatment for veterans with post-traumatic stress disorder (PTSD). She has also recently jointly led a project commissioned by the National Disability Insurance Agency, in which existing scientific literature was reviewed to determine the effectiveness of assistance dogs. Other current or recently completed projects include understanding the benefits and disadvantages of owner-trained assistance dogs, whether social interactions within the community increase when people with an intellectual disability go on outings with a therapy dog, how to prevent predatory behaviour in greyhounds, and the impact of courtroom dogs for survivors of sexual and family violence. In 2018, Dr Howell received a Research Excellence Award from La Trobe University.
