About me

\n

\n My name is Jan Malte Lichtenberg and I'm an applied machine learning scientist at Amazon Music ML in \n Berlin, where I work on the fascinating topic of personalizing music recommendations. More specifically,\n I work on offline policy evaluation and learning how to rank items from different content types. \n

\n Previously I completed my PhD at the University of Bath, working on bounded rationality in reinforcement learning \n with Özgür Şimşek. \n Before that I worked at the Center for Adaptive Behaviour and Cognition, directed by Gerd Gigerenzer, at the Max-Planck \n Insitute for Human Development in Berlin. \n

\n In my research, I try to inform machine learning models with insights from human decision making research, in particular from the study of simple decision heuristics. \n {/* I've received Master degress in statistics from ENSAE Paris and Humboldt University of Berlin. */}\n   Have a look at my Google Scholar profile, my github, or my (outdated) CV. \n {/* Follow me on Twitter to stay informed about new blog posts and other updates. */}\n

\n You can email me at maltelichtenberg ~at~ gmail.com\n
