He completed an internship in Internal Medicine at California Pacific Medical Center and a residency in Neurology at Stanford University Medical Center. He completed a fellowship in behavioral neurology at UCSF.

Alissa Nana Li, PhD

Associate Lab Specialist
Neurology

Alissa joined the Seeley Selective Vulnerability Research Laboratory in 2011 as a postdoctoral fellow. Her background is in neurodegeneration research. Alissa completed a BSc degree with honors in biomedical science in 2004 and a PhD degree in anatomy in 2009 from the University of Auckland, New Zealand, where she investigated the variable pattern of cortical neuronal loss in Huntington’s disease.

Alexander Ehrenberg

Lab Assistant
Neurology

Alex graduated from UC Berkeley in 2017 with a bachelor's degree in integrative biology (evolution, ecology, and organismal biology division) and molecular and cellular biology (developmental genetics division). He started at UCSF in Spring 2012 working under Dr. Pierre-Antoine Gourraud in the Multiple Sclerosis Genetics Research Lab. There, he developed skills in computational biology, informatics, and statistics.

Stephanie Gaus, PhD

Research Scientist
Neurology

Stephanie joined the Seeley Selective Vulnerability Research Laboratory in October 2007 as an Associate Specialist. Her background is in sleep and circadian rhythms research, including neuroanatomy. She completed a doctorate in neurobiology (CB Saper, Harvard University), a master's in medical science (Harvard Medical School), and a postdoc focusing on narcolepsy (E Mignot, Stanford University/Howard Hughes Medical Institute).

Peter Ljubenkov, MD

Clinical Fellow
Neurology

Dr. Ljubenkov received his medical degree from Temple University School of Medicine in Philadelphia. During his training he took part in the Medical Student Training in Aging Research (MSTAR) program at University of California, Los Angeles, where he investigated midbrain and basal ganglia pathology in patients with Alzheimer’s disease. He went on to complete his internship in internal medicine at University of California, Irvine, and his residency in neurology at University of California, San Diego.

Melanie Stephens, PhD

Assistant Professor
Neurology

Dr. Melanie Stephens is an Assistant Professor of Neuropsychology at the UCSF Memory and Aging Center within the Department of Neurology.

Marilu Gorno Tempini, MD, PhD

Professor
Neurology

Dr. Gorno Tempini is a behavioral neurologist with a doctorate degree in imaging neuroscience and directs the Language & Neurobiology Laboratory at the UCSF Memory and Aging Center (MAC). She obtained her medical degree and clinical specialty training in neurology in Italy. Dr. Gorno Tempini’s main focus was in behavioral neurology, particularly the neural basis of higher cognitive functions such as language and memory.

Katherine Possin, PhD

Associate Professor
Neurology

Dr. Possin is an Associate Professor of Neuropsychology at the Memory and Aging Center within the UCSF Department of Neurology. Dr. Possin’s research examines the neural bases of visual spatial and executive function impairments in neurodegenerative diseases including Parkinson’s disease, Alzheimer’s disease, and frontotemporal lobar degeneration. She develops cognitive assessment tools to support neurodegenerative disease diagnosis and monitoring, including virtual reality tests of navigation and tablet-based tools for clinical applications. Dr.

Aimee Kao, MD, PhD

Associate Professor
Neurology

Dr. Aimee Kao is a graduate of Brown University and the University of Iowa School of Medicine where she received her medical degree and a doctorate degree in physiology and biophysics studying the molecular mechanisms of insulin signaling. She completed an internship in Internal Medicine at the Beth Israel-Deaconess Hospital in Boston and a residency in Neurology at the University of California, San Francisco (UCSF), where she was Chief Resident. Dr. Kao participates in patient evaluation and management at the Memory and Aging Center.
