Dr. Nicholas Kyei

Postdoctoral Researcher

Dr. Nick Kyei is a physician specialist with many years of experience spanning clinical practice, public health practice, global health research, consulting, and teaching. He earned his medical degree from the School of Medicine and Dentistry at the Kwame Nkrumah University of Science and Technology, Kumasi, Ghana, and holds specialist qualifications in Public Health and Travel Medicine from the Ghana College of Physicians and Surgeons and the Royal College of Physicians and Surgeons of Glasgow, respectively. He also holds an MSc. in International Health from the Ruprecht-Karls-Universität Heidelberg, where he completed his Ph.D. in Epidemiology under Prof Dr. Dr. Sabine Gabrysch. His dissertation focused on investigating the potential role of maternal exposure to multiple mold toxins (mycotoxins) in foods for the development of specific adverse pregnancy outcomes – pregnancy loss, preterm birth, low birthweight, and birth small-for-gestational age. Nick Kyei works as a scientist in the Climate Change and Health Group at PIK and Charité – Universitätsmedizin Berlin. His research interests include exposure and health impacts of climate-sensitive environmental toxins (e.g., mycotoxins and pesticides), maternal newborn and child health epidemiology and emerging and re-emerging infectious diseases, including sexually transmitted infections, anti-microbial use and resistance, and special (high-threat) pathogens (e.g., SARS-CoV-2 & Lassa fever).
