Caroline Prioleau writes and designs content for the Memory and Aging Center and the Global Brain Health Institute. She is interested in using design and technology to share complex information and facilitate collaborations across clinical, research and non-medical groups. She also co-leads an oral history project, hear/say, that focuses on collecting personal stories about the experience of aging, dementia and caregiving.

Igor Prufer queiroz campos araujo

Behavioral Neurology Clinical Fellow

Igor Prufer Q.C. Araujo obtained his MD degree at the Federal University of Rio de Janeiro. He completed his neurology residency at Texas Tech University in Lubbock Texas being the chief resident in his final year of training. His current research interests include the benefits of multilingualism to cognitive reserve, the neural basis of decision making and socioeconomic factors affecting dementia care.

Pongpat Putthinun, PhD

Postdoctoral Fellow

Pongpat Putthinun is a health economist and postdoctoral scholar in the UCSF Memory and Aging Center. He joined the Decision Lab team, led by Dr. Winston Chiong, and is currently working on a project aimed at understanding how genetic predispositions to frontotemporal dementia influence decision-making in the pre-symptomatic phase. Through neuroeconomic methods, the research seeks to identify incidents of early impaired judgment that could lead to early intervention strategies to decelerate the onset of frontotemporal dementia.

James Qian

Clinical Research Coordinator

James was born and raised in Beijing, China. He graduated from Westmont College in December 2019 with a bachelor’s degree in psychology. His senior capstone project explored the effects of mindfulness meditation on people with mild cognitive impairment. 

After graduation, he worked as a program specialist at Friendship Center Adult Day Services in Santa Barbara, where he organized and led memory-strengthening activities for older adults with dementia.
