About me
I am a therapeutic endoscopist at Ersta Hospital in Stockholm, working across the Departments of Medicine and Surgery. My main interests include optical diagnosis, image-enhanced endoscopy, and endoscopic interventions.
My doctoral research at Uppsala University focused on high-resolution flexible endoscopy for the detection, treatment, and screening of HPV-related anal dysplasia. My thesis was entitled New Endoscopic Method for Diagnosing, Treating and Screening for Anal Precancer.
