I am an agri-environmental economics researcher focusing on the design of effective environmental policies in agriculture, integrating insights from behavioural economics and environmental psychology.
I hold a PhD from the Department of Agricultural Economics & Rural Development at the Agricultural University of Athens, Greece. Prior to my PhD studies I completed the Master program in Environmental Economics & Management at the Swedish University of Agricultural Sciences, Sweden. Also, I hold a Bachelor in Economics from the University of Piraeus, Greece.
Currently, I am employed as an associate researcher at the Agricultural Economics Research Institute (AGRERI), a part of the Hellenic Agricultural Organization - DIMITRA (ELGO - DIMITRA), where my research examines the factors that influence farmers’ adoption of environmentally friendly practices, with a particular emphasis on pest control.
More broadly, I am interested in how both economic and behavioural incentives—such as social norms, altruism, and uncertainty—shape decision-making at the individual and firm level. I also explore how policy instruments, including environmental taxes, subsidies, and regulations, can be designed to promote sustainable production and support the transition toward more socially responsible markets.
You can find more information on my academic background and research activities at my (up to date) Curriculum Vitae. Also, I maintain an account on both X/Twitter and BlueSky.
Outside of academia, I enjoy playing contract bridge (currently experimenting with a Precision-based system featuring canapé bids and transfer structures), reading crime fiction, watching films, travelling, and spending time with friends—usually over a good cup of coffee.

Contract Bridge
In my spare time, I enjoy playing contract bridge (at the Hellenic Bridge Federation's webpage you can find my current master points, and my historic ranking). Generally, I play SAYC with an intermediate 1NT opening (14-16 HCP, no 5M) and lot of gadgets (e.g., 4-way transfers, Bergen raising/2NT Jacoby, Dury, Inverted Minors, Checkback Stayman, UDCA, Woolsey, Gehstem, etc). Additionally, sometimes I serve as a director in local club dublicate bridge tournaments.
Currently, I am testing a canápe transfer-oriented precission bidding system, which was developed by Panos Stergianellis (inspired by the TOP3 bidding system). The following table illustrates the basic structure and non-competitive responses:
| Opening | Meaning | Response |
