Introduction
Between 2019 and 2024, I obtained a bachelor's degree in Biomedicine and a master's in Translational Physiology and Pharmacology at Karolinska Institutet. In addition to my main education, I collected approximately 80 ECTS in data science and machine learning. Next to this, I have been involved in various research projects at the intersection of physiology, data science, and physical activity or exercise.

Breast cancer and corresponding treatment strategies are associated with increased systemic inflammation. Exercise has been shown to reduce inflammation and is also associated with a long-term favorable prognosis in breast cancer survivors. The Optitrain randomized controlled trial (RCT) was designed to test the effect of high-intensity training (H...

BACKGROUND Exercise is suggested to reduce the recurrence risk in individuals with breast cancer. Evidence regarding relevant physiological mechanisms remains scarce. Here, we examined the association of inflammatory biomarkers with predicted recurrence events. METHODS The Optitrain randomized controlled trial consisted of 240 patients undergoing...

OBJECTIVE: This study aimed to examine differences in heart rate variability (HRV) across accelerometer-derived position, self-reported sleep, and different summary measures (sleep, 24h-HRV) in free-living settings using open-source methodology. APPROACH: HRV is a biomarker of autonomic activity. As it is strongly affected by factors such as physic...

BACKGROUND: Children spend increasing amounts of time on recreational screen media, which may lead to an obesogenic environment. OBJECTIVES: We investigated the association of trajectories of screen time across ages 3, 5 and 7 years with body composition at age 7 in the Odense Child Cohort. METHODS: Data were collected in the Municipality of Odense...

BACKGROUND Physical activity is a cornerstone in diabetes management; however, evidence synthesis on the association between physical activity and long-term diabetes-related complications is scarce. PURPOSE To summarize and evaluate findings on physical activity and diabetes-related complications, we conducted a systematic review and meta-analysis...
