In MultiTip, he studies the mechanisms that could be implemented to sustainably manage open access fisheries in Lake Victoria.


Dr. Tillmann Eymess


Tillmann Eymess is a Postdoctoral Researcher at the Research Center for Environmental Economics, Heidelberg University. His research uses experimental methods to study how environmental pollution crises interact with social inequality. With regards to MultiTip, his research focuses on new regulatory instruments for the use of common pool resources under weak enforcement. 


Philipp Händel

Phillip Headshot

Philipp Händel is a Ph.D. candidate at the department of Environmental and Behavioral Economics at the University of Kassel. His work in MultiTip focuses on how institutions and the social environment influence risk-taking and cooperative behavior of resource users such as fishers at Lake Victoria.


Johannes Kammerer

Johannes Headshot


Johannes Kammerer is a Postdoctoral Researcher at the Institute for Mathematics at Heidelberg University. In the MultiTip project, he investigates the interplay between the fish stock and fishery regulations using a size structured model of the Nile perch fishery.



Sorell de Silva 

Sorell Headshot

Sorell de Silva is Science Communication Officer for MultiTip at the Research Center of Environmental Economics (RCEE), Heidelberg University. She is also a Ph.D. candidate at the Department of Environmental Economics, Alfred-weber Institute of Economics, University of Heidelberg.  She is interested in studying tools that can be used for fisheries management and wildlife conservation in developing countries. In MultiTip, she studies the use of subsidies as novel instruments for incentivising compliance to gear regulation for fisheries management at Lake Victoria.


Pia Pico 

Pia Headshot

Pia Pico is a Ph.D. candidate at the Department of Environmental and Behavioral Economics at the University of Kassel. Her research interest lies in the experimental investigation of cooperation problems of individuals. In the MultiTip project, she investigates the influence of factors such as resource scarcity and migration, on the sustainable resource management of resource users at Lake Victoria

Partners from Lake Victoria

We also work with fisheries biologists from local partner organisations in the three riparian countries, Tanzania, Uganda and Kenya.

LaLvfo Logoke Victoria Fisheries Organization (LVFO) is a specialised institution of the East African Community with the mandate to coordinate sustainable management and utilisation of the fisheries resources across the three riparian countries of Lake Victoria. LVFO provides direct input for the research project and plays a key role in translating the research findings into policy.

Tanzania Fisheries Research Institute (TAFIRI), the Ugandan National Fisheries Resources Research (NaFIRRI) and the Kenyan Marine Fisheries Research Institute (KMFRI) are the three fisheries institutes that are mandated with sustainable management of the fishery. These partners have co-designed MultiTip and facilitate fieldwork (providing enumerators, technical assistance, translation and logistical services) and access to participants for studies.
