Fundamental research in Machine Learning and Graphs. The main focus of my Ph.D. was in graph-theoretical models for supervised and unsupervised learning, as well as clustering, multitask learning and recommendation algorithms. In particular I discovered properties of existing distance functions on graphs and developed novel methods for local clustering, quantization and friend recommendation. My research lead to publications at top-tier international conferences (AISTATS, ICML, NIPS, COLT) and was funded by Max Planck Institute for Intelligent Systems.
Additionally, I worked as a tutor for the lecture “Advance Algorithms” and “Machine Learning” at University of Hamburg, a M.Sc. level course covering a broad range of advance algorithms in computer science and Machine Learning techniques (classification, regression, unsupervised learning, etc.)

Working on recommender systems for large scale data. I proposed a novel local similarity function for recommending new friendships in Tuenti Social Network. The similarity function takes the temporal information of the edge creation process into account. Experiments on Tuenti social network with more than 12 million users showed that this method significantly outperforms alternative link prediction methods.
