Liana Machado

Tel:+64 3 479 7622

Associate Professor Liana Machado's primary areas of expertise are neuropsychology and cognitive psychology. Research in her laboratory investigates the mechanisms and machinery underlying healthy brain functions and the cognitive deficits that emerge as a result of brain disease and healthy aging. Associate Professor Machado has published extensively in high impact international journals, and these articles have been cited in many other research articles around the world. She collaborates with scientists in Europe and the USA, as well as within New Zealand.

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.
