”My goal is to complete my ongoing PhD projects and continue our good specialized collaboration.”

Birgit Stark was born in Köln in 1955. In 1992 she moved to Sweden, where she married Andreas Stark, professor in orthopaedics.

Birgit obtained specialist competence within surgery and plastic surgery in Germany. She completed her PhD in 1999 at the Department of Neuroscience,  Karolinska Institutet, and became an associate professor in plastic surgery 2007. She has various scientific interests related to her clinical activity.

Birgit is responsible for the care of patients with facial paralysis at Karolinska University Hospital since 2005. Many new treatment strategies have been introduced and are under scientific evaluation. Birgit also has a special interest in women with breast cancer and was the main supervisor of a dissertation project where the PhD thesis defence was held in 2010. On mission of occupational compounds within plastic surgery she has established a quality register for breast implants, which has now gained international interest.

Since 2001, Birgit cooperates with Associate professor Karin Strigård, and later on also with Professor Ulf Gunnarsson. Their coollaboration within the research group has led to many joint projects that illustrate the abdominal wall function from different illness perspectives. Birgit has been the main supervisor of a PhD project where the abdominal wall function during abdominal wall diastasis was studied. This project was defended in 2012. A dissertation regarding reconstruction of giant incisional hernia was defended in November 2016. Here, Birgit was a co-supervisor.

Pia works at Sunderby Hospital. Her research concerns parastomal hernia, and her disputation in June 2015 was within this field.

At present, Pia is joint supervisor of the PhD student Christoffer Odensten.

STOMAMESH is a randomized study, where the method of using mesh as prophylaxis against parastomal hernia is evaluated. Currently, one year data is being reviewed. Within the research group, 3D ultrasound as a method of diagnosing problems related to stomas has been developed and evaluated, and a study is ongoing where this method will be studied further.
