Dr. Karris’s major research interests are:


Maile Karris, MD, graduated first in class from the John A. Burns School of Medicine at the University of Hawaii. She completed her Internal Medicine Residency at Oregon Health and Sciences University and her Infectious Diseases fellowship at the University of California San Diego, where she currently resides as an Associate Professor of Medicine in the Division of Infectious Diseases.

Her effort is evenly divided between clinical duties in the HIV medicine outpatient clinic and infectious diseases inpatient consultation and in the performance of HIV clinical and translational research. Dr. Karris has trained under Drs. Douglas Richman, Davey Smith, Richard Haubrich and Celsa Spina to better understand the immunology of HIV and its role on clinical outcomes.

Research and Education

Currently, Dr. Karris’ research interests stem from “bedside-to-bench” in that she pursues research questions that directly respond to the day-to-day needs of her patients. Examples of her current research interests include a better understanding of the barriers and facilitators that contribute to poor HIV linkage and retention, a better understanding of the biology and delivery of PrEP for HIV prevention and the impact of inflammation and other factors on the successful aging of persons living with HIV. To accomplish these goals, she is a member of UC San Diego’s Center For AIDS Research Clinical Research Core.

Dr. Karris also participates in the mentoring and education of medicine residents and infectious diseases fellows historically participating in UC San Diego’s medical microbiology and HIV pharmacology courses along with educational conferences in the departments of medicine and infectious disease and community based and international lecturing on various HIV topics.
