OBJECTIVE	Research or development position in one of the following (or similar) areas: Distributed Systems, Middleware, Communication and OOT, Networking Large-scale reliable data dissemination (e.g. video on demand): SRM, probabilistic broadcast Reliable and Fault-Tolerant Systems Message Buses (publish/subscribe) Components / design patterns for networks / reliability Position must be in California (Greater Silicon Valley area preferred) Optional: continue work on JavaGroups
EDUCATION	Post-Doc, Cornell University Dec 1999 PhD Computer Science, University of Zurich Nov 1997 Masters degree in Computer Science, English and Economics, University of Zurich June 1992
WORK EXPERIENCE	Post-Doctoral Researcher 1997-1999 Computer Science Dept, Cornell University, Ithaca NY Work on reliable group communication toolkit (JavaGroups) (Java). Implements fault-tolerance through redundancy: service requests are sent to a logical group of servers instead of a single server. As long as at least one server in the group is functioning, the service as a whole is available. Focus on reusable object-oriented building blocks for group communication, especially for protocol development Advisor to several student projects using JavaGroups: distributed whiteboards including chat and video/audio streams, RMI extension (modification of rmic to broadcast requests to groups instead of single servers), Multi-User Dungeons, total order protocol Teaching CS100 sections Researcher 1994-1997 IBM Research Laboratory, Zurich, Switzerland Network Management Group PhD thesis on CMIP/SNMP/Corba based network management (C++). Use of various different management models (SNMP, CMIP, Corba) through a Corba-based unified model (client side). Implemented by parsing model definition (e.g. SNMP MIB, CMIP GDMO/ASN.1) into a metadata repository, dynamic access at runtime by metadata use and adapters (e.g. Corba's Dynamic Invocation Interface). OSI TMN/6000 CMIP agent development toolkit (C++). Implemented saving an agent's MIB to persistent storage using ObjectStore's OODBMS. Collaboration with ObjectStore on implementing very large MIBs (hundreds of thousands of objects). This work resulted in an IBM product (TMN/6000, part of NetView/6000). Conducted performance study on how the TMN/6000 agent scales to multiprocessor systems (SP2, SMP). Suggested improvements to development division (IBM Networking Division, Raleigh). Knowledge Engineer 1992-1994 Intelligent Systems Engineering AG, Taegerwilen, Switzerland AI-based configuration management software product (C++). Guided user-performed configuration of complex products by capturing configuration rules/dependencies as AI rules. Final configurations are correct in that they satisfy all rules. AI-based error diagnostics software product (C++). User is guided through fault-trees in diagnosing a problem and correcting it. Co-op 1989-1992 IBM, Zurich, Switzerland Design/implementation of a dealer commissioning system (C++, DB2). Data is entered into local DB2 database and periodically uploaded to MVS DB2 database. Implemented GUI (OS/2 presentation mgr), DB2 database access and host access (HLLAPI). Assistant Teacher 1988-1989 Detroit (MI), St. Cruz (CA) International exchange program, teaching German at HS level Programmer 1985-1986 Swiss Army Replicated databases for intelligence-gathering (MS SQL Server, C++, Visual Basic). Intelligence (flight tracking data) gathered at various outposts is replicated into central DB, where data mining extracts essential information. Implemented entire system, replacing old Access-based system with MS SQL Server.
