About Me


Welcome to my home page at Memorial University. First, let me tell you a bit about myself. I hold a Joint Honours Pure Mathematics and Computer Science Bachelor of Mathematics degree from the University of Waterloo. I started my Masters in Electrical and Computer Engineering at the Memorial University of Newfoundland in September 2000 under the supervision of Dr. Cecilia Moloney, and completed it in May 2003. The title of my thesis was "Methods and Applications of Irregular Sampling and Scattered Data Interpolation of Digital Images".

My Ph.D., also under Dr. Cecilia Moloney, was successfully defended in January 2008. The concentration for my thesis was on Non-linear Partial Differential Equation Models for Image Processing, and more specifically the development of new high-quality variational image decomposition models along with applications such as texture discrimination and denoising of oriented texture. These decomposition models separate an image into the sum of cartoon (piecewise smooth) and texture components, along with possibly a noise component. Image decomposition is a common first step to the solution of many image processing problems, and this led me to investigate the simultaneous solution of multiple image processing problems, because often there is a synergy between various problems which can be used to improve both the quality and efficiency of any solutions. I held an NSERC Postgraduate Doctoral Scholarship to pursue this research. I have presented my research at major international conferences and have begun submitting manuscripts from my Ph.D. to journals. I am also a reviewer for the IEEE Transactions on Image Processing, the SPIE Journal of Optical Engineering, and was a member of the Technical Program Committee (Signal Processing/Multimedia) for the IEEE Canadian Conference on Electrical and Computer Engineering (CCECE) 2009.

Previous research and scholarly interests have included symbolic computation and computational biology. I recently completed a postdoctoral fellowship which started in February 2008 with the Seismic Laboratory for Imaging and Modeling at the University of British Columbia. In the Spring 2010 term, I taught ENGI 1020, Introduction to Computer Programming, in the Faculty of Engineering and Applied Science at Memorial University. I am currently a Senior Research Engineer at Rutter Incorporated and am teaching ENGI 4892, Data Structures, in the Spring 2012 term.
