An expert in HIV and TB prevention, control, and treatment, Daniel has spent the past eighteen years leading public health programs and implementation studies in resource-limited settings in Kenya. He has played a pivotal role in developing and testing new service delivery models to improve access to HIV treatment and has contributed to product redesign efforts for HIV prevention tools, including digital solutions. His experience also includes serving as a frontline healthcare provider in these settings.
Over the last four years, Daniel has transitioned from infectious diseases to planetary health, integrating his implementation science expertise with interdisciplinary approaches to tackle the health impacts of climate change. He holds an MBChB from the University of Nairobi, an MPH from the University of California, Berkeley, and is currently pursuing a PhD at Charité University, Berlin. His PhD research focuses on the effects of climate-induced heat stress on the working capacity of Kenyan farmers with HIV. It uses novel technologies like wearables for personal monitoring and environmental sensors to study physiological responses to environmental changes in real-world settings.
Daniel's research interests have expanded to encompass adaptation to various climate-induced hazards affecting vulnerable populations, such as heat stress, climate-sensitive infections, droughts, floods, and storms. He emphasizes co-creating solutions with target populations, ensuring that communities actively participate in improving their well-being, rather than being mere recipients of interventions.
He is currently a co-investigator in a trial testing climate-adaptive housing to reduce malaria and heat stress in rural communities of western and coastal Kenya. His work remains grounded in human-centered design, aiming to improve health outcomes through collaborative, community-driven interventions.
