I lead the machine learning research group of the Cloud Information Services Laboratory (CISL) at Microsoft. I am also a member of the Apache Software Foundation and was the inaugural PMC chair (VP) of Apache REEF. My work focuses on machine learning techniques, systems therefore and applications thereof. Recently, I have been heavily involved in systems building for these applications, both Apache REEF and Microsoft-internal ones.
- Apache REEF: A standard library for writing high performance applications on Big Data clusters.
- ScalOps A domain specific language for distributed, larger scale data analytics and machine learning.
- DIOS: A large scale machine learning library used at Yahoo!
- CofiRank: A collaborative filtering algorithm that supports predicting the ranking of items as opposed to mere rating.
- BMRM: Open source, modular and scalable convex solver for many machine learning problems cast in the form of regularized risk minimization problem.
- Elefant: A machine learning toolbox. My contributions include a bridge that renders UIMA annotators into feature extraction tools for machine learning. This code is Open Source under the Mozilla Public License.
- DkPro: A set of UIMA annotators developed by TU Darmstadt.

- For three years, I worked at Yahoo! Research. My focus there was anti-abuse and web scale machine learning.
- I obtained my PhD as a student in the graduate school for the improvement of e-learning at the computer science department of the Technische Universität Darmstadt, Germany. I worked on applications of machine learning in elearning. To do so, I was lucky enough to gather support by two supervisors: Max Mühlhäuser (TUD) and Alex Smola.
