Prof. Clive Gray (PhD)
Clive is head of Division of Immunology at the University of Cape Town, Institute of Infectious Diseases and Molecular Medicine and Department of Pathology, with a joint appointment to the National Health Laboratory Service. He holds a faculty positions as an Adjunct Professor in the Department of Immunology, Duke University, North Carolina, USA. Prof Gray’s early research was in transplantation immunology and understanding allo-recognition and innate immunity in solid organ transplantation. Subsequently, he moved into HIV/AIDS research, seeing this as a priority in the South African context. He was awarded the prestigious James Gear Fellowship in 1995, which allowed him to work at the Center for AIDS Research at Stanford University as a post-doctoral fellow. Since then he has been actively involved in the scientific agenda of vaccine development in South Africa including directing a SAAVI and HIV Vaccine Trials Network (HVTN) southern African Central Immunology Laboratory at the National Institute for Communicable Diseases. He has published over 90 papers on various aspects of the immune system. Since moving to UCT, his research has shifted to understanding how HIV exposure impacts on immune checkpoint balance in infants and mucosal/epithelial tissues. He has a keen active interest in implementing novel teaching and learning strategies around immunology and is the creator of Immunopaedia (www.immunopaedia.org), originally funded by the Elizabeth Glaser Pediatric AIDS Foundation International Leadership Award. He is the vice chair of the Clinical Immunology Committee of the IUIS and works closely with the Education Committee around devising regional immunology workshops in Africa.
One received her PhD in Clinical Sciences at the South African TB Vaccine Initiative (SATVI) from the University of Cape Town in 2014. As a doctoral fellow at SATVI, she carried out research to understand the role that memory T cells play in protecting against TB disease. Her work provided novel immunological tools to characterize the memory phenotype and function of TB antigen-specific CD4+ T cells after vaccination and in infection. In 2015, she joined the HIV Vaccine Trials Network (HVTN) and leads the endpoints team that is studying cellular immune responses to HIV and TB vaccines. Her team works on intracellular cytokine staining assays to determine which vaccines to take further in clinical trials. One has also worked on TB vaccine trials within the organization, one in infants and another in adolescents, that were designed as an experimental medicine trial to allow comprehensive profiling the immune responses after vaccination with three TB vaccines. The aim of this work is to inform the larger Aeras 040-40 prevention of infection trial, should an efficacy signal be found. As co-investigator on these studies, she has worked with the team that laid the groundwork for the proposed research by developing assays that would allow them to gain as much information about the potential correlates of prevention/risk. She also established strong ties with the TB research community to ensure that their work was of the highest standard and was relevant to the field. One has molecular and flow cytometry assay skills, experience in clinical trials, and the application of ISO15189 quality management standards in a research laboratory setting. One retains a staff scientist position at Fred Hutch Vaccine and Infectious Disease Division.

Dee is a skilled and inquisitive clinician with an insatiable scientific curiosity. She possesses excellent teaching, organizational and problem solving skills, combined with the proven leadership ability to make decisions, negotiate and explore novel ideas and execute them and work co-operatively with others. She is a protagonist by nature and a positive and effective optimist in action. She believes she is fortunate to have two perspectives when dealing with patients and their conditions, being a lupus warrior herself. She is a wife and a mother of two children. Living with Lupus has helped give her purpose more clarity and help her acknowledge that every moment in life is an act of faith. There is currently a growing prevalence and increasing awareness of rare inborn errors of immunity and other common acquired and congenital immunology disorders and very few clinical paediatric immunologists in the country to care for them. Awareness of immune health and illness has become an invaluable skill in the midst, and aftermath, of a pandemic. Dee sees joining SAIS as an opportunity to embark on a new milestone in her career, which will bring invaluable experiences that will allow her to become a successful, innovative professional and assist her in accomplishing her future goal of training Immunologists for and in South Africa. She is hoping to prove that one can chase ones dreams despite all odds and that by being a lupus warrior, she can survive this condition on her terms by rising and raising others in the process.
