LFC projects

One of the special features of medical studies in Oldenburg is an early introduction of students to research. In the so-called Longitudinal Research Curriculum (LFC), students first learn the most important basics of scientific work in small groups and later in the context of a larger research project. The students should learn to deal critically with research work, to conduct their own research and to write scientifically. The aim is to research a self-selected or predefined scientific question and finally to write their own research paper. The questions range from literature research to patient surveys or sample analyses.

At the Department of Visceral Surgery, we always have current LFC topics on offer on various visceral surgery and oncology topics, as well as on topics related to the areas of "technology in the operating theatre" and "human-machine interaction". These projects are often related to one of our current research projects. Depending on the respective interest, we can offer retrospective studies, studies with patient contact, or literature research leading to meta-analyses, for example. And of course, students can also propose topics themselves.

Doctoral theses

We offer the opportunity for medical doctoral theses with us on request. Supervision is provided by both our medical and scientific staff. In addition, there is regular exchange between the doctoral students, for example in the form of our doctoral colloquia.

The next colloquium is planned for autumn this year. Medical students are also welcome to attend in order to gain a better insight into our research activities. If you are interested, please feel free to contact

Current PhD students:

  • Amelie Damann: Neuronal correlates of expert cognition during laparoscopic simulation - an EEG study.
  • Sebastian Flerus: Quality of life after rectal cancer surgery
  • Dennis Fried: Preoperative magnesium and calcium supplementation in thyroid patients - RCT
  • Pavel Gladki: Impact of the Corona pandemic on visceral surgery care reality - a bicentre study
  • Dmitry Khmara: TEP after recurrence of initial TAP or TAPP for inguinal hernias

Bachelor and Master Theses

Interested students from other departments can also write their theses with us. These are integrated into our current research projects.

Currently, a bachelor's or master's thesis is available for students of neuropsychology or physics, technology, medicine (see below).

CURRENT: Bachelor's or Master's thesis to be assigned

Virtual and augmented reality (VR and AR) are increasingly being used to support the preparation and performance of operations. In preparation, the main interest is which method leads to better results or, for the same results, which is easier to use, requires less attention and creates less cognitive load. Doctors and medical staff in training should plan several liver resections using the available VR and AR systems. In addition, if they can detach enough attention from the main task, they should respond to an acoustic oddball by pressing a button. The performance in this secondary task and the EEG signals measured during this task will be used to determine the attention bound by the primary task. In addition, subjects still rate their cognitive load in self-report. Beyond this research goal, this series of experiments serves to test the measurement of EEG during the use of VR and AR, and to establish a measurement and evaluation protocol. These will be a necessary basis for future measurements in this field. The results of the study will be published in relevant journals.

The work will be jointly supervised by research assistants from the University Hospital and staff from the Department of Psychology. We are looking for a person with a background in neuropsychology or physics, technology, medicine. The work can be carried out at the level of both a Bachelor's and a Master's thesis.
