• Sparsity-Based Algorithms for Inverse Problems Research output

  Inverse problems are problems where we want to estimate the values of certain parameters of a system given observations of the system. Such problems occur in several areas of science and engineering. Inverse problems are often ill-posed, which means that the observations of the system do not uniquely…

• Learning and Behavior Problems in Education: Challenges and Solutions

  The program group Learning and Behavior Problems in Education: Challenges and Solutions strive to find solutions to the learning and behavior challenges faced by preschool and elementary-school children, youth, and young adults in education. In doing so, the group focuses on cognition and behavior and…

• Negotiating Peace with Your Enemy: The Problem of Costly Concessions Research output

  Why do some parties fail to settle conflict, even after long periods of fighting? ISGA PhD candidate Valerie Sticher suggests that costly concessions often stand in the way of a negotiated agreement. Conflict party members not only care about their in-group's welfare, but also want to avoid rewarding…

• Severe behavioral and emotional problems, special education and youth care Research project
