About me

I am an aspiring researcher, physiotherapist, and sports scientist with a great interest in hip/groin and hamstring injuries, and data analytics.

I serve as the Head of Sport and Data Science in Football Club Nordsjælland, a Danish premier league football club with associated youth academies in Denmark and Ghana (rated as one of the world’s best academies according to Scouted Football), where I focus on structured data collection and associated analyses to support physical trainers and physiotherapists.

I am also a postdoctoral researcher at the Sports Orthopedic Research Center - Copenhagen (SORC-C) at Hvidovre Hospital; an International Olympic Committee (IOC) research center centered around prevention, diagnostics and treatment of musculoskeletal problems.

I completed my PhD in 2022 which was conducted at SORC-C and was entitled “Femoroacetabular Impingement Syndrome: Patient Acceptable Symptom State, Return t Sport, and Hip Muscle Strength After Hip Arthroscopy”.
