Most courses I teach are in my primary area of research, namely computer graphics. I also teach a few software engineering courses as well.

In fall 2009-10 I will be teaching the following 2 courses:

1. Introduction to Game Development (undergraduate)  – COMP 376
2. Software Engineering Case Study (graduate)  – SOEN 6591

Previously, I have taught the following courses:

1. Computer Graphics (undergraduate) – COMP 471
2. Advanced Computer Graphics (graduate) – COMP 6761
3. System Software (undergraduate) – COMP 229 and SOEN 229
4. Advanced Rendering and Animation in 3D games (graduate) – COMP 7661
5. Quality Assurance and Software Management(undergraduate) – SOEN 383 and SOEN 384
6. Multimedia Computing (graduate) – COMP 691T

I have also supervised a large number of students for their Bachelors level projects, and Masters and PhD students for thesis. Most of these are in the areas of Geometric Modelling, Image Synthesis, Machine learning applications and Visualisation.

Until now, 9 of my doctoral students have successfully completed their PhD degrees in computer science. During the period 2005-2009, 10 Master’s students graduated under my supervision/co-supervision. Presently, I supervise/co-supervise 5 Doctoral research students and 2 Masters students.

Infrastructure

The 3D Graphics laboratory is well equipped with state-of-the-art equipment. The present set-up includes:

• A fast, high resolution two-head, structured light based 3D half--body scanner which can help rapidly create 3D geometric models of complex real world objects including human faces,
• A powerful 8 node, 16 processor graphics cluster, with 1 GB Inifiniband ® backbone,
• 16 high end 3D graphics workstations with programmable graphics processing units (GPUs),
• An virtual reality experimentation set-up for research in immersive environments consisting of:
  • Wide field of view stereo Head Mounted Display (HMD) system with opaque display screens, stereo headphones, and wireless 3 degrees of freedom orientation sensors for immersion in a totally virtual  reality environment,
  • Wide field of view stereo Head Mounted Display (HMD) system with see-through display screens, stereo headphones, and wireless 3 degrees of freedom orientation sensors for indoor/outdoor immersion in an augmented  reality environment,
  • 2 spherical digital video cameras with very wide field of view providing for high resolution real world visual sensing capabilities,
  • Stereo projector with two wireless 3D glasses providing for research in collaborative immersive environments,
  • Full body motion capture system for research in animation and haptic interfaces

Projects

The present emphasis in most research projects is on computational techniques to deal with very large data obtained through:

• sensors like3D/medical scanners, image/video cameras or motion capture device,
• logs from web servers,
• data results from simulation/analysis programs.

Along with my students and research collaborators, research investigations include new techniques for 3D manifold reconstruction, 3D scan data processing, use of machine learning in motion capture data, visual analytics for web usage data, visualization of protein folding, software visualization, heritage applications, virtual and augmented reality for training applications.
