Collin Liu, MD
Behavioral Neurologist with Neuroimaging Expertise (PET and MRI)
Specialist in Cognitive Health and Disorders
Diplomate, American Board of Psychiatry and Neurology
Diplomate, American Board of Nuclear Medicine

Collin Liu, M.D. is a behavioral neurologist with additional expertise in molecular and functional neuroimaging (PET and MRI), board-certified in both neurology and nuclear medicine. He specializes in cognitive disorders, such as Alzheimer’s disease, vascular dementia, Lewy body dementia, frontotemporal dementia, and normal pressure hydrocephalus. His expertise in neuroimaging helps provide early and accurate diagnosis for timely management and participation in clinical trials. Dr. Liu is committed to providing compassionate and personalized care in a holistic and multi-disciplinary approach.

Dr. Liu grew up in Taiwan and Los Angeles. After college at UC Berkeley and medical school at New York Medical College, he received dual residency training in neurology at University of Pittsburgh Medical Center, and nuclear medicine at Mallinckrodt Institute of Radiology/Washington University in St. Louis. After residency, he completed a behavioral neurology fellowship at UCLA/West Los Angeles VA Medical Center with Dr. Mario Mendez.

Dr. Liu held faculty position as Assistant Professor of Neurology and Radiology at USC, where he taught medical students and residents, and developed novel imaging methods to help understand the connection between brain vessel health and memory loss. He was also Director of the Memory Assessment Center at Eisenhower Medical Center in Palm Desert, where he pioneered cognitive assessment by telemedicine. He published numerous peer-reviewed papers and book chapters, and supported multiple clinical trials during this time.

Dr. Liu is also fluent in Mandarin and Taiwanese.
