    Djelili Biaou is a final-year PhD student in Immunology at Doctoral School 563, Université Paris Cité, affiliated with the UMR-261 MERIT research unit. Originally from Benin, he earned his Master's in Immunology there before joining the doctoral program in Paris, having previously contributed to several research projects in Benin, including Deworm3, HYGESMO, and CoHyS-Pal.


    His research focuses on the immunological and genetic determinants of host susceptibility to tropical parasitic diseases, with particular emphasis on gestational malaria and its impact on maternal and child health. He investigates the biological mechanisms underlying morbidity and mortality during pregnancy, postpartum, and early childhood — specifically identifying human and parasitic molecules contributing to postnatal susceptibility and assessing the functionality of maternally transferred antibodies in infantprotection.


    In this episode, he shares findings and insights from his research into malaria immunity in mothers and infants, highlighting the roles of antibodies and other immune cells. He also talks about how his experience has been shaped through international exposure and a bilingual status.

    Limpho Thipane is a PhD student at the University of Cape Town and an emerging tuberculosis researcher whose work spans immunology, infectious diseases, and neuroscience. Her Master’s research, titled “Regulators of neuroimmune functions in the manifestation of central nervous system tuberculosis in the absence of microglia”, investigated how microglial depletion influences immune responses, pathogen control, and neuroinflammation in central nervous system tuberculosis (CNS-TB).


    Her academic journey has included extensive work in tuberculosis, particularly CNS-TB, with a particular interest in understanding host–pathogen interactions and the role of immune cells, such as microglia and alveolar macrophages, in disease progression and control. Her ongoing PhD research expounds on this area of work with a focus on the non-psychoactive, cannabidiol.


    Limpho spends her spare time discussing science with and mentoring high school students, and leads science engagement projects for Eh!woza and the African Research Society.



    In this episode, she discusses her fascinating journey to becoming a brain TB scientist, findings from her research, and her ongoing commitment to disseminating science, engaging communities, and mentoring the next generation.

    Annie Elong is a Research Instructor in the Center for Vaccine Innovation at the La Jolla Institute for Immunology. Elong received her Ph.D. in Immunology investigating the role of autoreactive T and B cells in patients with Multiple Sclerosis (MS), an autoimmune disease affecting the Central Nervous System (CNS). Her research focus has since broadened, to human infectious diseases and mouse models in the group of Dr. Sujan Shresta at La Jolla. She has led key projects aimed at understanding the adaptive immune response to infection with flaviviruses, particularly dengue and Zika, contributing towards the development of efficient vaccines. During the pandemic, Elong investigated the role of pre-existing immunity to human common cold coronaviruses and the interplay between antibody and T cell responses in shaping the outcome of SARS-CoV-2 infection.


    In this episode, Elong talks about her journey through and contributions to the field, which has crisscrossed T cells, antibodies, autoimmunity and vaccines. In addition, she discusses the critical roles pan vaccines could play in the fight against viral diseases and shares part of her ongoing plans to elucidate how T cells mediate neuropathologies associated with viral infections.

    Dr. Lorraine Pfavayi is a Postdoctoral Research Associate at the University of Edinburgh and a TIBA Postdoctoral Fellow. She holds a DPhil in Clinical Medicine from the University of Oxford, where she investigated fungal allergic diseases in regions co-endemic with parasitic infections.


    Her current research focuses on developing point-of-care diagnostic tools for schistosomiasis, a neglected tropical disease commonly linked with fresh water snails. She is also involved in the Affected Voices programme, which promotes the inclusion of people with lived experience of neglected tropical diseases (NTDs) in health policy and service delivery.


    Her work is driven by a commitment to integrating basic science with global health policy to deliver equitable, context-relevant solutions for vulnerable communities.



    In this episode, Pfavayi discusses the need for context-relevant approaches to addressing the burden of neglected tropical diseases (NTDs) in Africa and highlights how her ongoing work centers local contexts, community persepctives, and African-led approaches in the development of solutions for NTDs.

    Launching in April 2025, our special TB Immunology series and first-ever disease-focused series dives deep into the science, challenges, and success stories behind the fight to end tuberculosis.


    We’re joined by leading scientists whose work in TB prevention, diagnosis, treatment, and vaccine development is shaping the current landscape of the disease in Africa and globally.


    Whether you're actively involved in TB research or simply curious about the field, this experience promises to be both eye-opening and engaging.



    The seventh and final episode in the series features Professor Mohlopheni Jackson Marakalala who is currently the Director of the South African Medical Research Council (SAMRC) Centre for Tuberculosis Research at Stellenbosch University (SU), South Africa.


    Marakalala completed his PhD in Chemical Pathology at the University of Cape Town (2008), receiving the Bronte Stewart Research Prize for the most meritorious PhD thesis. He then completed a total of 8 year postdoctoral training; 4 years in the Institute of Infectious Disease and Molecular Medicine (IDM) at UCT and 4 years in Immunology and Infectious Diseases at Harvard TH Chan School of Public Health. 


    Between 2016 and 2019, he was a Senior Lecturer at UCT and a Visiting Scientist at Harvard. From 2019 until his recent appointment as the Unit Director of the SAMRC Centre for TB Research, he has been a Wellcome Trust International Fellow and Faculty member at Africa Health Research Institute (AHRI) and an Associate Professor at University College London (UCL).


    His laboratory’s primary interest is on infectious diseases, particularly immunopathogenesis of Tuberculosis, with an aim of developing host-directed therapies targeting mediators of lung damage. His other interests are in understanding strategies utilized by mycobacteria to survive various arms of the immune system.


    Work in his lab has been funded by grants from SA Medical Research Council, Wellcome Trust and Bill and Melinda Gates Foundation. Personal achievements include recognition as a ‘Rising Star’ at the 2019 Grand Challenges meeting, NRF Emerging Researcher Excellence Award (2018), SA Medical Research Council Scientific Merit award (Silver medal) (2016); UCT 2016 College of Fellows Young Researcher Award; and the Next Einstein Forum (2016) Fellowship.


    In this episode, he talks about how we may rethink funding for TB research in light of recent cuts which have dealt the field a heavy blow. In addition, he shares some of the plans and perspectives he brings to his recent role as Director of the SAMRC Centre for Tuberculosis Research.
