My research foci are on the advanced studies of corrosion processes in ferrous and non-ferrous alloys as well as the integration of design in the classroom. Many of my research projects on corrosion are in collaboration with industrial partners and my work has been published in international peer-reviewed journals as well conference proceedings and presented at international conferences.

 

My work on design integration in the classroom has focused on creating new and engaging laboratories for year 1 & 2 of the engineering program as well as in more specialized higher level courses, such as the Corrosion & Degradation of Materials and the Materials Engineering courses

TEACHING AND DEMONSTRATION EXPERIENCE

 

 Teaching:


Engineering Graphics I

The object of the class is to provide students with conceptual design experience, team work experience, and computer drafting experience; develop the following skills: engineering free-hand sketching, 3-D visualization, and reading of engineering drawings. An integral part of the class is Design Project, focused on design as the essence of engineering, the process of design and reporting.

 

Engineering Thermodynamics

Fundamental definitions and concepts are reviewed. Engineering analysis of properties, heat, work and systems is carried out. The zeroth, first, and second laws are presented. Ideal gases and mixtures, real gases, liquid-vapour relations, availability, irreversibility, entropy concepts, and flow in nozzles and diffusers is examined. Gas and vapour power cycles are studies with emphasis on cycle analysis.

 

Mechanics I: Statics

Course for engineers designed to teach the students the concepts of force, movement, and equilibrium in a 2-D and 3-D environment.

 

Introduction to Materials Engineering

This course is designed to introduce the students to crystallography, mechanical properties, materials selection, phase diagrams, and basics of corrosion. Laboratories are designed to introduce the students to some casting and welding techniques, to the use of mechanical testing equipments and to the proper interpretation of experimental data.

 

Corrosion and Degradation of Materials

Designed to help the students with designs of structures, choices of coatings, and inhibitors. Laboratories in this course were designed to introduce the students to real life problems with open ended solutions. The course also introducesthe students to some electrochemical techniques, such as Electrochemical Impedance Spectrocopy, Electrochemical Noise and Cyclic Voltammetry to name a few.
