Management Team

Dr. Andy T. Ogielski

President and Chief Scientist, Co-founder

Andy has more than 25 years experience encompassing data networking and telecommunications, Internet protocols, wireless systems, software systems, and scientific computing. Before founding Renesys, he was a research professor at Rutgers University where he led multimillion-dollar government funded projects such as scalable Internet modeling and simulation software (SSFNet) that pioneered analysis of large networks exceeding 100,000 multiprotocol hosts and routers. At Bell Communications Research (now Telcordia), Andy built pioneering high-speed network packet traffic recording and analysis systems, fraud detection software, streaming distributed video servers, and network operations software systems. As a research scientist (MTS) at AT&T Bell Laboratories from 1982 to 1989, Andy was involved in very large scale scientific computing. In 1984 he designed and built a special-purpose supercomputer that ran Monte Carlo simulations of complex materials several times faster than a Cray supercomputer built the same year. Andy holds a Ph.D. in theoretical physics from the University of Wroclaw, Poland.

Jim Cowie

Chief Technology Officer, Co-founder

Jim has more than 15 years entrepreneurial and software development experience in high performance computing, network modeling and simulation, web services, and security.
