Objective: To obtain a challenging position for summer interns in the field computer networks.

Education

4/94 - 6/99: Technical University Berlin, Germany

Diploma program in Electrical Engineering (with distinction).

Academic interests

Multimedia networking: Voice over IP, conference control protocols.

Network architectures: Integrated Services, Differentiated Services, Active Networks.

Work experience

8/99 - present: Research Institute for Open Communication Systems, Berlin, Germany

Scientist at the Competence Center for Global Networking with research projects in active networks

and in voice over IP.

- Designed and implemented a software module in C/C++ under Unix/Linux that remotely controls

network devices via the telnet protocol.

5/99 - 7/99: Fulltime intern at Novedia Inc., Berlin, Germany

Involved in the development of an Internet conference system.

- Designed and partly implemented a class library in C++ that enables a platform independent input,

output, and mixing of audio streams under Windows NT and Linux.

- Implemented network applications under Linux.

- Extended functionalities of the Video Conference Tool (vic) under Linux to enable message exchange via a message bus.

- Designed and implemented a control module that controls the Robust Audio Tool (rat) and the Video

Conference Tool (vic) via a message bus under Linux.

10/98 - 5/99: Diploma thesis at Research Institute for Open Communication Systems, Berlin, Germany

Implemented the Adaptive Packetization/Concealment (AP/C) algorithm in the Network Voice

Terminal Tool (NeVoT). The AP/C algorithm exploits the long-term correlation of speech signals to influence the packetization interval at the sender and to conceal the lost packets at the receivers.

1/98 - 9/98: Pre-diploma thesis at Research Institute for Open Communication Systems, Berlin,

Germany

Designed and implemented a charging and accounting protocol that works with the Resource

ReSerVation Protocol. The charging and accounting protocol keeps track of network resources

reserved by users, reliably exchanges accounting information between network nodes, and fairly shares the costs between users.

11/97 - 4/99: Student employee at Department of Intelligent Networks, Siemens Inc., Berlin, Germany

Involved in design, test, and administration of advanced telephone services.

5/97 - 10/97: Student employee at GMD Fokus Research Institute for Open Communication Systems,

Berlin, Germany

Involved in the development of the Multicast Integrated Server, a Multicast Address Resolution Server for ATM clients with QoS support.

Skills

Programming languages: HTML, x86 assembly language, Pascal, C/C++, and Java.

Operating systems: DOS, Windows, Linux, and Unix.
