On Wednesday, June 15, 2016, two successful disputations of the Department of Information Systems of the University of Kassel took place in the large hall of the ITeG : 

Frank Weiß defended his dissertation entitled "Consumerization: Enabling the Introduction of IT Services for Mobile Consumer Devices", Niroshan Thillainathan defended his dissertation entitled "Model Driven Visual Programming for Serious Games". 

Professor Dr. Jan Marco Leimeister congratulated both of them on their successful disputation and presented them with a doctoral hat individually designed by the scientific staff of the department.

Following the successful disputations, a small champagne reception took place, which gave the two disputants the opportunity to celebrate this important milestone in their lives in the circle of former colleagues, friends and companions and to exchange memories with a view to the common time at the chair.
