Some topics I am interested in 

Behavioural Operations Research, Behavioural experiments, Path dependence, Practice of modelling, Philosophy of modeling, Decision analysis, Portfolio decision analysis, Environmental decision making, Organizations, Operations, Software, 

Some research objectives

• Helping practitioners, users, and consumers of Operations Research methods
• Increasing understanding of behavioural aspects in OR and in modelling more widely
• Mitigating risks related to biases and human behavior

History

2015 Ajatuksia jatko-opinnoista

2018-2020 I worked in the industry (Finnair, Visma Consulting / Weoptit) on topics related to eg. supporting operational planning with optimization technology, software development, resource planning, prediction. This period expanded my knowledge, e.g., on working with customers, general management, project management, sales and marketing.
