She joined the UCSF Memory and Aging Center (MAC) in June 2024 as a clinical research coordinator in the Dementia Imaging Genetics Lab led by Dr. Suzee Lee, where she coordinates a study investigating the neurodevelopment of children from families with a history of frontotemporal dementia or Alzheimer’s disease

Alex Hernandez

Alex Hernandez, MPH

Clinical Research Coordinator

A graduate of Columbia University Mailman School of Public Health with a specialized focus in Epidemiology of Chronic Disease, Alex is deeply committed to enhancing healthcare literacy and fostering inclusivity and diversity within healthcare, particularly among underserved and vulnerable communities.

In his free time, he enjoy running around Lake Merritt in Oakland, listening to music, and hiking/camping.

Cesar Hernandez

Data Liaison

Cesar holds bachelor’s degrees in psychology and ecology from the University of California, Davis and a Master of Public Health in epidemiology from Boston University. Prior to joining the UCSF Memory and Aging Center, Cesar worked in the Women’s Health Clinical Research Center (WHCRC) at UCSF managing data for the San Francisco Mammography Registry (SFMR) database and various clinical trial studies.

Joe Hesse

Director of Innovation

Joe Hesse joined the Memory and Aging Center in 2002 and serves as the center’s Director of Innovation. His focus is the development of informatics and computational infrastructure in support of precision medicine. He works in collaboration with many groups and faculty across UCSF with the overall goal of delivering technology solutions to clinicians and researchers that are both scientifically agile and regulatory compliant.

Margo Heston, PhD

Margo Heston, PhD

Postdoctoral Scholar

Dr. Margo Heston is a postdoctoral scholar and an NIH F99/K00 fellow funded through the NIH Blueprint and BRAIN Initiative Diversity Specialized Predoctoral to Postdoctoral Advancement in Neuroscience (D-SPAN) program.

Hilary Heuer, PhD

Oculomotor Specialist

Dr. Hilary Heuer is an oculomotor specialist in the Boxer lab.

Tanisha Hill-Jarrett, PhD

Assistant Adjunct Professor

Tanisha Hill-Jarrett, PhD, is a neuropsychologist and an assistant professor of neurology at the UCSF Memory and Aging Center. Her research applies intersectionality theory to understand how psychosocial stressors and structural racism and sexism impact Black women’s cognitive aging and confer risk for Alzheimer’s disease and related dementias (ADRD).

Aidyn Hill

Aidyn Rose Hills, BA

Assistant Clinical Research Coordinator

Aidyn was born and raised in Portland, Oregon. In May 2024, she graduated from Whitman College with a bachelor’s degree in psychology and a minor in biology. She previously worked as a student researcher in the Psychology Department at Whitman College, investigating the effect of language framing on victim-blaming attitudes and prosocial behavior. Aidyn is now an Assistant Clinical Research Coordinator for the PET program in the Rabinovici Lab at the Memory and Aging Center.

Molly Hodul, PhD

Postdoctoral Scholar

Molly studied Neuroscience and Psychology at the University of California, Los Angeles. She then completed her PhD degree with Professor Peter Juo at Tufts University, where she investigated the regulation of the AMPA-type glutamate receptor by its deubiquitinating enzyme USP-46 in C. elegans. She identified two novel mechanisms by which USP-46 is stabilized and activated by two WD40-repeat proteins, WDR-48 and WDR-20, to promote AMPAR abundance and recycling to the neuronal surface. In the Kao lab, Molly will continue her research in protein homeostasis and degradation in C.

Brandon Holmes, MD, PhD

Assistant Professor

Brandon Holmes, MD, PhD, is an Assistant Professor at the Memory and Aging Center (MAC). He completed his clinical fellowship at the MAC and his post-doctoral research in the Department of Pharmaceutical Chemistry in the laboratory of James A. Wells, PhD, where he studies how microglia, the innate immune cells of the central nervous system, alter their proteome in the context of neurodegeneration and neuroinflammation. Learn more about his research here.

Kiet Hua, MD, PhD

Behavioral Neurology Clinical Fellow

Dr. Kiet (Robert) Hua completed a Bachelor of Science degree in Neurobiology, Physiology and Behavior at the University of California, Davis. During his undergraduate studies, he developed a love of research, studying animal behavior. He completed further research training at the University of Houston where he studied drosophila genetics. He completed his Medical Degree (MD) and Doctor of Philosophy (PhD) degrees at Albany Medical College. His PhD thesis focused on the study of primary cilia and their role in a category of neurodevelopmental disorders known as ciliopathies.
