• It's revealed: robots are more human than you dare to think :-)

I'm interested in communication and sociology since I started as an undergraduate at the university. In particular I favour Niklas Luhmann's theory of social systems. His theory is my underlying paradigm and I strongly encourage you to read his work.

I'm the MSc coordinator for the "Electrical" MSc degrees at the University of Glasgow and I'm teaching the Audio / Video engineering degree at the University of Glasgow.

• Digital Signal Processing
• Audio / Video Team Film Project (as part of the Audio / Video engineering degree at the University of Glasgow)
• Image processing (with openCV)
• Lighting for video (for team film project)
• Data acquisition in music processing
• Acoustics and Audio Technology (handout: Radiation from a loudspeaker, The acoustic wave equation)
• Final year and MSc projects I have supervised:
  Wireless ECG/EEG, audio exciter, optimising RunBot, muscle surface stimulator, autonomous robot with the MSP430, measuring performance data from a trumpet, investigating foot pressure and MEG while walking, ...
• Audio and visual perception
• Robot team design project
• Lighting for Theatre (way back in Germany)
• My teaching portfolio (which is sort of a dissertation in paedagogy lecturers have to write during their probation)
• I've designed the web page of the ECG lab which is now a reference page for e-teaching in medicine (German page). This is a screen shot.
• ECG/EEG preamp
• Heart/ECG lab in Germany
• Estimate the angle of the heart's electrical activity (JAVA-program)
• Browse the measurements of the ECG lab (JAVA-program)
