Former Team Members

Michael Brottrager

Research Assistant



I am currently studying in the Master’s programme of Economics at the Vienna University of Economics and Business. Focusing on Applied Econometrics, I am particularly interested in development of strategies to deal with problems of sample selection, endogenous treatment, and endogenous participation for ordinal, count, and binary variables. Furthermore, I have also strong interest on human capital and economic growth, dynamics of religious beliefs and scientific-economic development, migration, inequality and public sector economics. Before joining the TransRe Team, I worked as Data Analyst developing economic models for real time national and global poverty projections.

Besides being part of the TransRe Team, I am part of a small research group working on modeling global forced migration flows in the wake of the Arab Spring.

Vera Tolo

Research Associate/PhD Candidate


 2013 - 2016


I studied geography, sociology, and development economics at the University of Bonn, with a focus on vulnerability, food security, and migration research. For my final thesis, I examined the political ecology of food security in the context of oil production in southern Chad. The project was carried out in cooperation with the Centre for Research in Anthropology and Human Sciences Chad and Misereor. Currently, I am a research associate and PhD candidate with the RCR Project based at the Universities of Bonn and Cologne. Previously, I have worked as a trainer on intercultural learning and conducted interactive workshops for organizations like GIZ, Bayer, and Telecom in this regard. I am a native of Sarajevo and fluent in German and English.

I studied the Master in Geography at the University of Bonn. Prior to my studies, I spent three years travelling, mostly in Southeast Asia, where I had the chance to learn a lot about life while enhancing my intercultural experiences. My main regional interest is Southeast Asia, especially Thailand, where I also recently conducted an Internship in a large NGO. I am also interested in human-nature relationships of all kinds.
