About us
The Γ-opt (reads gamma-opt) research group is a part of the Systems Analysis Laboratory in the Department of Mathematics and Systems Analysis at Aalto University.
We develop research in the fields of Operations Research and Management Science, with emphasis on Optimisation, Mathematical Programming, and applications related to Production Systems Planning and Supply Chain Management.
If you are interested in positions, collaborations or exchange opportunities, please contact Fabricio Oliveira.
