Research focus

My research focuses on chronic inflammatory bowel disease (IBD) and eosinophilic esophagitis (EoE).
The focus here is on investigations into the epidemiology and natural course of these diseases in connection with current treatment options.
Furthermore, I am investigating the role and influence of environmental factors in combination with other risk factors – such as genetics, intestinal microbiota or psychosocial factors – for these chronic, immune-mediated diseases of the gastrointestinal tract.
The further development of drug, interventional and surgical treatment options is also an important focus. For this reason, numerous novel therapeutic approaches are constantly being researched at the USZ Study Center as part of multicenter studies and can be offered to interested patients.
