Resume - Tobias Mayr ==================== CornellUniversity 4104 Upson Hall Ithaca, NY 14853 Phone 607-255-9537 Fax 607-255-4428 E-mail mayr@cs.cornell.edu Objective --------- Position as a researcher, starting in August 2001. Academic Background ------------------- 1996 - 2001 Cornell University Ithaca, NY, USA PhD Studies in Computer Science Thesis on adaptive parallel data processing, Advisors Prof. Praveen Seshadri and Prof. Johannes Gehrke, Minor in Finance. My thesis work evaluates new distributed execution techniques in query processing systems (see research statement). The systems component of my work was within the context of the Cornell Predator OR-DBMS. I integrated the Java VM and client-site processing into the execution engine and rebuilt the Predator system as a parallel execution environment. I was teaching assistant for three courses at Cornell: an introductory class, a class on algorithms, and one on discrete structures. I gave guest lectures in advanced database courses and seminars. 1993 - 1996 Technische Universität München Germany Undergraduate Studies in Computer Science Vordiplom in Computer Science, Diploma Thesis on Mobile Network Algebras, Advisors Dr.Radu Grosu, Prof. Manfred Broy, Minor in Computational Linguistics and Philosophy of Language. I worked on software specification parsing and object-oriented type-checkers. Internships ----------- Fall 2000 Microsoft BARC San Francisco, CA, USA I worked with Dr. Jim Gray to design and implement a research prototype environment for record stream data exchange on a server cluster. Summer 1999 IBM Research San Jose, CA, USA I worked with Dr. Mary Tork Roth on the design and implementation of OLEDB data source integration for the Data Joiner distributed database product.

Future computer systems will process vast amounts of complex data in parallel environments that consist of many heterogeneous components. Active storage and network components, clients and external sites contribute their data, functionality and processing power to make data processing more scalable, flexible and powerful. These highly non- uniform processing environments must be integrated to form reliable and scalable data processing systems. My PhD work shows how new processing techniques can be used to allow parallel processing of data while adapting to the heterogeneity of the processing components. I parallelized the execution engine of an existing object-relational database system as a prototype for experimentation with the new parallel query processing techniques. My work demonstrates processing on asymmetric nodes in a cluster as well as the integration of external functionality on server and client sites. The underlying idea is that parallel systems must be aware of the heterogeneity of their components to process data efficiently and to fully integrate all components. In my future work, I want to apply these ideas to new environments, like mobile device networks, systems with intermittently connected clients or peer-to-peer architectures. I want to apply my ideas in actual applications to develop them as realistic solutions to real-world problems.
