I am a paediatrician and paediatric gastroenterologist. I am employed by the Medical University of Silesia in Poland and I work at the Clinical Hospital in Zabrze, in the Gastroenterology and Hepatology Department. In everyday practice, I have been treating children with gastrointestinal diseases such as abdominal pain, food intolerance, food allergies, obesity, inflammatory bowel disease, gastroesophageal reflux, celiac disease, and osteoporosis for 20 years. I have performed ultrasound examinations for almost 20 years and have completed several ultrasound courses in Poland. I am particularly interested in bowel ultrasound. I perform about 50 ultrasound examinations a week. I am the author and co-author of over 20 scientific publications in the field of paediatric gastroenterology. I am particularly interested in the problems of inflammatory bowel disease, such as complications of treatment; extraintestinal manifestation (osteoporosis, pulmonary involvement); and genetic alterations. Apart from the subject of inflammatory bowel disease, I am also interested in the use of ultrasound in the diagnosis of inflammatory bowel disease. I am the leader of several new projects using ultrasound for the diagnosis of constipation and perianal fistulas. I am an active member of the Polish Paediatric Society; the Polish Society of Gastroenterology, Hepatology, and Children; the European Crohn’s and Colitis Organisation; and the International Bowel Ultrasound Group.
