Donald obtained his Bachelor's degree in Biochemistry from the University of Bamenda (Cameroon) in 2016, following a research internship at the Faculty of Biology of Adam Mickiewicz University (Poznan, Poland). He then pursued a Master's degree in Molecular and Medical Biotechnology at the University of Verona (2019–2021), where he completed his thesis in the Laboratory of Pharmacology. His research focused on the bioenergetics of brain organoids, with particular emphasis on implementing the Seahorse platform to profile the metabolic activity of developing cerebral organoids. 

From October 2024 to October 2025, Donald joined Dr. Bottani’s lab as a PhD student from the Doctoral School of Poznan University of Medical Sciences to continue his research. His work aimed to investigate mitochondrial dysfunction in Noonan Syndrome associated with gain-of-function mutations in the Ptpn11 gene. 

Donald is deeply committed to studying mitochondrial dysfunction in the context of genetic disorders.
