Alzheimer’s Prevention Lab at UC San Diego

Welcome to the Alzheimer’s Prevention Laboratory directed by Dr. Judy Pa.

Our research is focused on identifying genetic and lifestyle risk factors for Alzheimer’s disease and developing innovative interventions for improving brain and cognitive health in older adults. Using a combination of cognitive, behavioral, and neuroimaging techniques, our primary goal is Alzheimer’s prevention.

The Alzheimer’s Prevention Lab is an academic research lab at the University of California, San Diego (UCSD) and a part of the Alzheimer’s Disease Cooperative Study (ADCS) and the Department of Neurosciences. Dr. Pa is Professor of Neurosciences and Co-Director of the ADCS and holds the Shiley Endowed Chair for Alzheimer’s Disease Research.

Recent News

2025

  • The lab is unlikely to accept new PhD students in fall 2026. We are unable to respond to individual inquiries due to the volume of daily emails. We wish you the best of luck on a successful application season.

  • The lab welcomes 2 new PhD students this fall: Andrea Gabay from the Clinical Psychology JDP and Emily Ager from the Public Health JDP - Health Behavior!

  • Laura Fenton, USC Clinical Psych PhD student, successfully matches with her first choice internship! UC San Francisco is so lucky to have her!

  • Big news to share that Dr. Megan Fitzhugh’s K22 Career Development Award has finally arrived! Congrats Dr. Fitzhugh!

  • Nancy Ortega (Neuroscience PhD student) is awarded the Elizabeth Young New Investigator Award at the annual OSSD conference!

  • Cynthia Nyongesa (Neuroscience PhD student) publishes her first first-author paper! on “Artificial intelligence-driven natural language processing for identifying linguistic patterns in Alzheimer's disease and mild cognitive impairment.”

  • Vahan graduates from USC with a PhD in Biostatistics! Congrats Dr. Aslanyan!

2022

  • Vahan Aslanyan was accepted into USC’s Biostatistics PhD program and will continue in the lab as a PhD student.

Nancy Ortega completed her first year rotations and officially joined our lab as a Neuroscience PhD student, while also earning a competitive NIH T32 fellowship.

Congratulations to Vahan and Nancy!

Aging and Alzheimer’s disease

The United States is experiencing a rapid explosion in the number of older adults. Cognitive decline in older adults is a major public health issue due to its high prevalence and estimated cost at $203 billion per year. Therefore, understanding the brain changes associated with cognitive aging is of critical importance. Our ability to distinguish successful aging from mild cognitive impairment, a preclinical stage of dementia, remains limited. Identifying individuals with MCI is essential as they are at increased risk of progressing to dementia, such as Alzheimer’s disease.

And it is even more important to identify individuals at risk for cognitive impairment as we know that neuropathology can accumulate decades before the onset of symptoms. While there are prospective disease-modifying treatments for Alzheimer’s disease on the horizon, there are still no effective diagnostic biomarkers. Brain imaging has emerged as a promising method for in vivo investigation of neural changes due to underlying neuropathology.

Positions

Our research is supported by the National Institute on Aging (NIH), foundation grants, and local university support.

POSTDOCTORAL FELLOWSHIP (updated Sep 2025)

Applications are being accepted for an in-person postdoctoral fellow position with a focus on lifestyle factors and/or women’s brain health. Our research lab is located in La Jolla, CA in a state-of-the-art clinical research center. Successful candidates will have a PhD in cognitive neuroscience, neuroscience, psychology, physics, biomedical engineering, or a closely related discipline. Previous experience and track record in R, neuroimaging data analysis, and big data analytics are a plus.

UCSD PHD STUDENTS

At this time, we are unlikely to accept a new PhD student for Fall 2026.

UCSD RESEARCH INTERNS, MASTERS THESIS STUDENTS, AND UNDERGRADUATE WORK STUDY

UCSD students with an interest in aging, dementia, lifestyle factors, and women’s brain health are encouraged to contact us regarding available unpaid internships. Our students come from majors in neuroscience, psychology, medicine, computational sciences, engineering, or exercise physiology. We are an interdisciplinary group and welcome those with common interests and passions for aging, dementia, and women’s health research.

All interested candidates should contact Dr. Judy Pa: jpa@health.ucsd.edu
