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 Mathematical programming and Optimisation under uncertatinty. The appliations of our research includes areas such as Energy systems, Production and operations planning, Supply chain management, and Humanitarian and healthcare logistics.
Follow the updates of our group on our LinkedIn page.
If you are interested in positions, collaborations or exchange opportunities, please contact Fabricio Oliveira.

Projects
.js-id-current
- Funding organisation: Academy of Finland
- Funding period: Jan 2022 - Dec 2024
- Summary: This project attempts to enable large scale flexibility of electricity consumption at the residential scale, which in turn will allow more variable power generation, such as wind power and photovoltaics, to be cost effectively integrated in the energy system.
- Funding Organisation: Academy of Finland
- Funding period: Sep 2020 - Aug 2024
- Summary: The project will further develop the decision programming framework as a methodology for modelling and solving multi-stage decision problems under uncertainty
