I do not offer any thesis supervision.

Ulrich is a researcher at the chair for Software Engineering of Business Information Systems (sebis) at the Technical University of Munich (TUM) since September 2017. He holds a master's degree in Information Systems from TUM and wrote his master thesis about Analysis of Use Cases of Blockchain Technology in Legal Transactions.

His research focuses on the data analytics of public Blockchains such as Bitcoin, Ethereum and others. Public Blockchains offer rich datasets, consisting of all transactions and smart contracts executed by the users of the respective platform. With this data, one can cluster addresses to users, detect mixing services disguising the origin of funds, trace cross-Blockchain transactions or find other user behaviour. He is especially interested in bytecode analytics of Ethereum Smart Contracts. Ethereum offers with over 5.6 Million Smart Contracts the richest set of decentralized applications, allowing a search for design patterns, developer behaviour or used standards.

Ulrich is also very engaged in the education with regards to Blockchain and Distributed Ledger Technologies. He is the creator and main organizer of the lecture Blockchain-based Systems Engineering in the summer term. With this lecture, Ulrich supports students to get a technical foundation of different types of Blockchains and want them to be able to evaluate future developments in this area. After this course, students are able to design and implement own applications with Blockchain technology. Besides offering a lecture, Ulrich is responsible for the organization of the seminar Technical Analysis of Existing Blockchain Applications in winter term. Additionally, Ulrich is the scientific advisor to a number of students with regard to their bachelor's and master's thesis or their guided research.

Besides his activity at the chair, he is also a speaker at various events about Blockchain. He gives talks at international conferences, at companies like Allianz or IBM, but also at other universities and occasions. He participated in the Omega Tau Science Podcast about Blockchain and Smart Contracts. If you are interested in him giving a talk at your event, please leave him a mail.

In his free time, Ulrich likes to participate in Hackathons. He won the Hyperfit Blockchain Hackathon in Copenhagen in August 2017 and the IBM Blockchain Hackathon in Munich in November 2017. He talked about the complexities of Bitcoin at the Blockchain4.Business hackathon and was also a member of jury at the famous ETHBerlin in September 2018.
