Marek S. Wartak received an MEng in Electronics (Electrical Engineering) with concentration on Solid State Technology and a PhD in Theoretical Physics with emphasis on Quantum Liquids, both from Wroclaw University of Technology, Poland. Wartak has over 30 years of experience in semiconductor physics, photonics and optoelectronics, analytical methods, modeling and computer-aided design (CAD) tools. During his career, he has worked at Nortel Networks and the National Research Council His work has taken him to Canada, California and Europe. Since 1990, he has been employed by Wilfrid Laurier University, presently as full professor at the Department of Physics and Computer Science, also an adjunct professor at Physics Department, University of Waterloo and a member of Guelph Waterloo Physics Institute, all in Ontario, Canada.

I conduct research in computational photonics. It involves theoretical modelling and computer simulations. My current research interests are:

• Non-equilibrium Green's functions (NEGF) modelling of active photonic devices.
• Optical properties of various heterostructure compounds.
• Transmission-line method description of semiconductor lasers.
• Vertical cavity surface emitting lasers (VCSEL).
• Dynamical processes in solar cells.
• Compensation of losses in metamaterials.

• Wilfrid Laurier University Merit Award for 2003 2004 Academic Year.
• University Research Professor 2005-2006.
• Wilfrid Laurier University Merit Award for 2012 2013 Academic Year.

I have research assistantships opportunities for undergraduate and graduate students interested in simulations of photonic devices. Some other research areas can also be considered like, metamaterials, active plasmonics, nanostructures and optical properties of semiconductor heterostructures. Please contact me for more information.
