Summary:

I am an artificial intelligence researcher excited by new challenges in basic research and eager to apply my knowledge and experience in application projects.

I have a high success rate in writing research project proposals and am happy to lead projects teams towards successful and timely completion of the project resulting in patents, various awards and scientific publications. I also like to transfer my knowledge and experience to clients, project partners and students as well as to the general public. Click to see the list of projects that I participated in or the list of my publications.

My research work includes:

  • research and development of data mining techniques that allow the user to trade classifier accuracy for comprehensibility or vice versa,
  • development and application of planning techniques that enable robots to invent new execution plans based on examples of successful plans, and
  • research of search pathology in order to save “thinking” time by preventing futile search in computer games.

I have applied my knowledge in development of:

  • intelligent door system that acts as a human doorman,
  • unobtrusive elderly monitoring system that recognizes falls and unexpected daily activity patterns related to a health problems,
  • ambient intelligence system that identifies patients activity (e.g. walking, sitting) and estimates his/her energy consumption from accelerometer data,
  • expert system that considers vast array of health related parameters in order to determine health condition degradation or rehabilitation improvement,
  • intelligent surveillance system that learns usual movement patterns and recognizes unusual events (thefts, staff negligence, unauthorized access) based on real-time location system,
  • smart house system that learns human behavior in order to suggests house automation schedules with optimal trade-off between comfort and energy expenditure,
  • intelligent laboratory system that predicts future anomalous operation of laboratory equipment (e.g. refrigeration systems) and unusual lab environment conditions (e.g. humidity fluctuations).
