Lea Christiane Rundfeldt is a medical student at the Charité Berlin and will graduate in 2020. After her long-term activity in competitive sports, she decided to study medicine aiming to specialize in sports medicine. In 2017, she joined the Center for Space Medicine, to pursue her interest in human adaptation and resilience to extreme environmental exposition. In her doctoral thesis, she specifically explores heart rate variability (HRV), as to assess both physiological and psychological stress, as well as resilience, in ultramarathon competition – working together with Dr. Martina Maggioni and Dr. Mathias Steinach. Additionally, she has explored muscle metabolism and sarcopenia-like models in microgravity analogs – this representing another example of human physiologic adaptation to exceptional conditions.

In her spare time, Lea Christiane Rundfeldt enjoys sportive and outdoor activities such as running, cycling and rock climbing.

Scientific fields of interest: heart rate variability, physiological and psychological resilience, physical performance, ultramarathon, sarcopenia, mTOR signaling.
