I am employed at Warsaw University of Technology in the Division of Computer Graphics of the Institute of Computer Science since 1998. I achieved M.Sc. degree at Faculty of Electronics and Information Technology, Warsaw University of Technology in 1998 r.

Current activities in the Institute of Computer Science:
  • Administrator of linux server „Galera” in the computer laboratory of the Institute of Computer Science,
  • I conduct laboratory classes related to different courses,
  • Webmaster of the WWW page of the Computer Graphics Division,
  • I am organizing the faculty programming contest together with Andrzej Pająk. Local faculty contest (in polish) www site is available at following address: galera.ii.pw.edu.pl/konkurs/. The faculty contest is intended as qualification to the „Akademickie Mistrzostwa Polski w Programowaniu Zespołowym” and „ACM Central Europe Programming Contest” contests,
  • I give lectures at Postgraduate Studies „Computer Science” on: Development of WWW sites, Linux Operating System and Introduction to Windows environment.
Research interest:
  • machine learning - e.g. support vector machines (SVM, LS-SVM),
  • digital processing and analysis of biomedical signals (ECG and other),
  • computer networks,
  • Linux operating system,
  • Digital Signal Processors,
  • real time operating systems.
Labs and classes:
  • „Digital Signal Processors” lab (lecture given by H.Kowalski)
  • „Computer Graphics” lab - OpenGL and 3DStudio MAX exercises
  • „Peripheral Devices and interfaces” lab - chip cards and VFAT file system exercises.
  • „Introduction to logic circuits” lab
  • „Computer architecture” lab
