HIV–infection in children, adolescents, and pregnant woman

Research Description

Dr. Keller's research focuses on developing effective, non-invasive tools to detect the harmful effects of HIV on the central nervous system of perinatally, HIV-infected youth. There is a critical need to improve early detection of HIV brain damage in order to maximize brain health for these youth at a time when therapy may be changed to improve outcome. Dr. Keller has worked with her physicist colleagues at David Geffen School of Medicine at UCLA to study several newer brain MRI techniques in this population, including both one- and two-dimensional magnetic resonance spectroscopy (MRS) in addition to brain morphometry techniques and diffusion tensor imaging. Currently, she and her UCLA colleagues (Drs. Albert Thomas and Manoj Sarma) are assessing baseline functional MRI connectivity as a tool for clinical follow-up in these patients.
