Andrzej Nowak is a staff researcher at CERN openlab - a collaboration of CERN and industrial partners such as HP, Intel, Oracle and Siemens. He holds a Master Engineer degree in Computer Science from the Gdansk University of Technology, specializing in distributed applications and internet systems. Andrzej's early research concerned operating systems security, mobile systems security, and wireless technologies. During his studies in 2005 and 2006, he worked at Intel, where he researched custom performance optimizations of the Linux kernel and took part in developing one of the first implementations of the IEEE 802.16 "WiMax Mobile" standard. In January 2007, soon after obtaining his diploma, he joined openlab as a Marie Curie Fellow sponsored by the European Commission. Andrzej's current research is focused on performance tuning, parallelism and modern many-core processor architectures. Another significant area of his work is the teaching of these topics at courses both within and outside of CERN.
