I am an Assistant Professor of Economics at McMaster University in Hamilton, Ontario, where I moved after my PhD at the GSEFM at Goethe University Frankfurt. Alex Ludwig was part of my PhD committee. My research interests broadly lie in quantitative macroeconomics, with applications to the role of taxes in heterogeneous agent models, entrepreneurship, and (female) labor supply across countries and over time.
I am a PhD student at the University of Cologne’s Center for Macroeconomic Research. Alexander Ludwig is my second supervisor and a coauthor. My research focuses on labor markets from a macroeconomic perspective: in my job market paper, I analyze the role of occupational switching for realized wage dynamics. In other work with several coauthors, we analyze wage and earnings risk over the business cycle and over the life cycle and ask, e.g., how well households or the government can provide insurance against individual level risk. I work with quantitative models and analyze micro data sets using parametric and non-parametric methods.
I work in the directorate for Employment, Labour and Social Affairs of the OECD. Alexander Ludwig was my doctoral supervisor and is coauthor of several papers. My research deals with questions related to demographic change and inequality. In my thesis I focused on quantified large-scale overlapping generations models as regards methodology. More recently, I ventured into applied microeconometrics in order to estimate the effects of social policy from panel data sets.
I am an assistant Professor at the University of Groningen.
My research interests are on household economics, especially old-age related risks, health-related topics and saving puzzles, as well as behavioral Macro. I mostly work quantitatively using micro-data and structural dynamic heterogeneous household models.
Currently, I am a postdoctoral researcher at the Center for Economic Research (CER) of the Swiss Federal Institute of Technology Zurich (ETH Zürich). In 2012, I received my PhD in economics from the University of Mannheim under the supervision of Prof. Tom Krebs and Prof. Felix Kübler. My research covers optimal lifecycle savings and portfolio choice, pension systems, asset pricing in general equilibrium, and computational methods. I address these topics quantitatively in incomplete markets models with heterogeneous agents. Alexander Ludwig is my co-author on several papers and continues to be a great mentor.
I wrote my thesis on "Intertemporal Allocation with Incomplete Markets" at the macroeconomics unit of the MEA Institute in Mannheim, which, at the time, was headed by Alexander Ludwig. My research on overlapping generations has since appeard in the Journal of Mathematical Economics, the Journal of Macroeconomics, and the Journal of Population Economics. Currently, I work on public and private information games at the Max Planck Institute for Research on Collective Goods in Bonn.

I am a Graduate Student in Machine Learning at the Imperial College London. I first met Alexander Ludwig at the University of Cologne and got fascinated by life cycle modeling and his lectures on public policy. Afterwards, I joined the Center of Macroeconomic Research as a student research assistant to Professor Ludwig and Professor Helge Braun. Under the supervision of Nils Grevenbrock I contributed to a research project that dealt with potential moral hazard problems at the intersection of unemployment and retirement insurance. While analyzing large panel datasets (e.g. PSID, HRS, CPS), I quickly found my passion for the computational aspects of inference and high-dimensional statistics. Since then I have diverged from my original path and have focused on Data Science and interdisciplinary applications of approximate Bayesian Inference. My main research interests focus on Hierarchical Reinforcement Learning and episodic memory. In October 2018 I will join the Einstein Center for Neurosciences Berlin as a PhD fellow.
I am currently working in the Deutsche Bundesbank’s economics directorate. I am in charge of developing an Overlapping-Generation-Model which is used for analysis of sustainability questions of social security systems as well as for impact assessment of policy tools. Alex Ludwig was my PhD supervisor at the University of Cologne and is my co-author of several papers. My current research lies at the cross road of macroeconomics, labor and health economics. Methodologically, I work quantitatively using micro-data and structural dynamic heterogeneous agent models.
I am currently heading a team in the Deutsche Bundesbank’s financial stability directorate. The team is responsible for developing analytical tools for the analysis of financial stability questions as well as for impact assessment of policy tools. Prior to taking up this position, I worked in the Bundesbank’s Macroprudential Policy Division. My post-academic professional career started in the European Central Bank in 2011, where I worked in several directorates. Before that I completed my PhD-thesis at the MEA in Mannheim entitled “Human Capital Investment and Population Dynamics”. Alexander Ludwig was my mentor and co-author of several papers. My older research interests focus on questions around population ageing, human capital and growth. More recently, I ventured into modelling the observed income- and wealth distribution and quantify effects of fiscal policy on welfare as well as into identifying the build-up of risks within the household sector and modelling the effects of borrower based instruments on the risk outlook and more broadly, on the macroeconomy. Methodologically, I mostly rely on structural models in a traditional life-cycle setup.
