Professional background and credentials

Joanna’s academic path began at the Poznan University of Medical Sciences, where she earned her Bachelor’s and Master’s degrees in Dietetics, eventually obtaining a Ph.D. in Medical Sciences. Her research primarily explores the genetic and clinical aspects of obesity and metabolic disorders, a passion she pursued during a traineeship in Copenhagen and while working on the NoHoW project at the University of Leeds. Currently serving as an Assistant Professor, she combines lecturing with the coordination of Phase II and III clinical trials focused on metabolic and cardiovascular health. She also applies her expertise to science popularization; at Omni Calculator, she has developed numerous tools that make medical and sports data accessible to the general public.

Achievements

Joanna’s academic excellence was highlighted when she defended her doctoral thesis with distinction. Her contributions were further honored a year later with the Rector’s Scientific Award at the Poznan University of Medical Sciences, recognizing the significance and quality of her research.
