His research interests include infectious disease epidemiology, maternal immunology, and integrated public health interventions. He employs meta-analytic and field-based methodologies to assess the impact of preventive therapies and genetic factors on perinatal outcomes in malaria- and HIV-endemic regions.

The recent publications show a consistent focus on pregnancy-associated malaria, genetic susceptibility to HIV transmission, and the combined burden of malnutrition and infection. His work often involves large-scale data synthesis and community-based trials, emphasizing evidence-based policy formulation for low-resource settings.

Dr. Ayisi has received funding and support from leading global health institutions, including:

• National Institutes of Health (NIH)
• Centers for Disease Control and Prevention (CDC)
• National Research Foundation
• Natural Sciences and Engineering Research Council of Canada
• Department for International Development (UK)
• Association Française contre les Myopathies

He has advised or collaborated on numerous research projects aimed at reducing maternal and child morbidity in Africa. While no formal students are listed, his leadership in multi-institutional studies suggests a mentorship and collaborative role. His research has been instrumental in shaping malaria prevention policies, particularly regarding intermittent preventive therapy in pregnancy (IPTp) and integrated maternal health programs.

Dr. Ayisi has contributed to major initiatives such as the Maternal Malaria and Malnutrition (M3) program and has developed novel methodologies for placental immunology studies. His work bridges laboratory science, epidemiology, and public health implementation, often conducted in partnership with local and international research teams in Kenya and beyond.
