FELLOWS
The Complexity Center cultivates a curiosity-driven, interdisciplinary, and collaborative research environment. As part of our Fellowship programme, we are pleased to host scholars who can both contribute to and benefit from the Center’s ongoing research while engaging with new perspectives, data, and methods. We encourage Fellows to share their own expertise, approaches, and insights to foster a spirit of mutual learning and collaboration.
Lea Schumacher
Lea Schumacher, PhD, is a psychologist and postdoctoral researcher at the University Medical Center Hamburg-Eppendorf (UKE-Hamburg) in Germany. She aims to apply innovative statistical-analysis approaches to provide new perspectives on (mental) health-related research questions. Her doctoral research at UKE-Hamburg centred on a network approach to psychopathology, a framework that conceptualises mental disorders as complex interacting systems. Specifically, she examined associations among psychological symptoms to better understand dynamic processes during psychotherapy and to predict long-term treatment outcomes. At the Copenhagen Health Complexity Center, she intends to broaden this approach by researching how complex interactions among social, environmental, and psychological factors contribute to mental-health outcomes. She joins the Center as a Fellow from March to June 2026.
Cornelia Wagner
Cornelia Wagner, PhD, is a social epidemiologist with extensive experience in life-course research and quantitative analysis of observational data. Her work explores the development and reproduction of social inequalities in health over the life course, including between generations, using large longitudinal data sets. At the core of her research agenda is a commitment to understanding how social structures and systems become embodied over time and across generations, ultimately producing patterns of advantage and disadvantage that shape people's lives. Currently, Cornelia is employed as a postdoctoral researcher at the Population Health Laboratory (#PopHealthLab), University of Fribourg, Switzerland, and she joins the Complexity Center as a Fellow from February to May 2026.
