Research Abstract
Human immunodeficiency virus (HIV) has had a catastrophic impact on individuals and communities around the world. It is estimated that over 35 million people are currently infected with this virus and a similar number have died of HIV/AIDS related causes. While combination antiretroviral therapy (ART) is capable of preventing disease progression, many people living with HIV do not have access to these drugs. ART is also complicated by drug-associated side-effects, the development of viral resistance, and significant financial expense. Moreover, because current therapies do not cure HIV infection, infected individuals have to continually take ART for life to suppress outgrowth of virus. Developing a cure for HIV is therefore an important research priority. My research goals are to work towards a safe and effective HIV cure by better defining the reservoirs that persist during ART and developing methods to eliminate them.

My laboratory uses in vitro and in vivo experimental models to study HIV infection, pathogenesis, treatment, and cure approaches. This includes in vitro model systems to study HIV infection and persistence in T cells and macrophages, and in vivo humanized mouse models of HIV infection. We are particularly focused on developing new approaches to eliminate the latent reservoirs of HIV that allow the virus to persist through years of drug treatment.
Short Biography
My undergraduate Bsc (Hons) degree in Medical Microbiology and Ph.D. in Molecular Virology were both obtained at the University of Edinburgh in Scotland, UK. From there I moved to UCLA as a postdoctoral scholar and subsequently a junior faculty member in the UCLA Department of Medicine. During this time I developed a research program that utilizes a range of model systems (including humanized mice) to study HIV latency and advanced new HIV cure approaches. I established my research laboratory at UCI in 2020, with appointments in the Departments of Microbiology and Molecular Genetics and Medicine (Division of Infectious Diseases).
