Valentina Parma is Research Assistant Professor in the Department of Psychology at Temple University, and the chair of the Global Consortium for Chemosensory Research or GCCR. She studies the ways in which unconscious cues, such as odors, influence typical and atypical social and motor behavior using behavioral and physiological methods across development. Recently the COVID-19 pandemic has added a new dimension to her research in clinical olfaction to understand how smell, taste, and chemesthesis (spicy/cooling sensations) are affected by COVID-19. She is also invested in supporting and advising peers and students, advocating for women scientists, particularly through her work with Women In Olfactory Science and consulting for CyNexo on the development of odor-delivery methods.
