In addition to lecturing on her areas of expertise to university students, Associate Professor Machado serves the community through public presentations and media appearances, as well as through fundraising and service on scientific advisory committees.
Liana earned a bachelor's degree in psychology at UCLA in 1994 and a PhD in Neuroscience at UC Davis in 1998. After conducting postdoctoral research for five years in the laboratory of a neurologist in the UK, she joined the Department of Psychology at the University of Otago in 2003.
