About Me

I grew up in Cape Town, South Africa during most of my childhood. Having witnessed the devastating effects of AIDS on the South African population, this sparked in me a deep passion to pursue a career that encompassed care for people living with HIV (PLWH). Fortunately, I was able to build on my interests in antiretroviral pharmacology and clinical expertise in HIV through pharmacy school at UNC Chapel Hill and my PGY2 HIV Specialty residency in SUNY-Buffalo under worldwide leadership and mentoring of Drs. Angela Kashuba and Gene Morse, respectively. I then worked as a HIV clinical pharmacist in both pediatric and adult HIV populations with worldwide experts Drs. Mary Paul and Joseph Gathe for 9 years in Houston, Texas.

During the last few years of my appointment at University of Houston I became more interested in pharmacogenomics since I observed first-hand the benefits it had on some of my patients with HIV who had other medical problems such as depression. Having also worked some time as a pharmacogenomist in Houston this further gave me a greater appreciation of the field. At the University of Houston, I invested in research that focused on complementary alternative medicine such as epigallocatechin gallate (EGCG) in green tea, crofelemer and vitamin D.

After gaining excellent HIV clinical and research experience in these areas, I then accepted a position at WSU. This faculty appointment has provided numerous opportunities for expanding and sharing my teaching interests in HIV and pharmacogenomics, including special populations, pharmacology related to cardiology, renal, pulmonary, immunology, infectious diseases and oncology areas as well as a residency preparation elective. I also offer APPE rotations in HIV/pharmacogenomics academia including an annual HIV/AIDS precision medicine rotation in Cape Town, South Africa. My current research interests include education and scholarship of teaching in HIV and pharmacogenomics as well as clinical implementation of pharmacogenomics to improve treatment outcomes in both the general and HIV populations worldwide.

In my spare time I like to…

I enjoy the beauty that Washington state has to offer throughout the year, love to travel, enjoy exercising, and am a sports fanatic.

Why WSU?

WSU gave me opportunities to broaden my teaching capacity, invest in global education, and to meet the clinical needs of the rural community.
