Alidad Amirfazli, PhD, PEng, FCSME, FEIC

Professor & Chair of the Department of Mechanical Engineering

Prof. Amirfazli founded the Department of Mechanical Engineering in 2013. He formerly held the Canada Research Chair in Surface Engineering at the University of Alberta. He has more than 250 scientific contributions, many in prestigious peer reviewed journals; and given many invited talks at international level. Dr. Amirfazli has been the recipient of the Martha Cook Piper Research prize, Petro-Canada Young Innovator Award, and Killam Annual Professorship. In 2014 he was inducted into the Royal Society of Canada’s College. He has been a consultant with various companies in USA, Europe, and Canada. He is a Fellow of EIC, and CSME.

Research:

Prof. Amirfazli’s group combines fluid mechanics and heat transfer concepts with physiochemical and thermodynamic principles to tackle many complex problems seen in aerospace, energy, and materials sectors. The group has produced exciting results in wetting behavior of surfaces, drop adhesion and shedding, drop impact, icing, direct laser patterning of self assembled monolayers and super-hydrophobic surfaces. The work is well recognized internationally; active collaborations with various research groups around the world allows many students to spent time in top laboratories or interacted with researchers we host annually in our lab from Germany, Italy, Spain, China, France, Belgium, UK and Switzerland.

Paul O’Brien, PhD

Associate Professor

Research:

The Advanced Materials for Sustainable Energy Technologies Laboratory (AM-SET-LAB) is currently focused on the design and development of spectrally selective, photothermal, and thermal energy storage materials that control and utilize solar energy and radiant thermal energy for the advancement of sustainability.

Research areas include: (1) thermal photonic materials designed to control the directionality and spectral distribution of the emissivity and absorptivity of thermal radiation with applications in solar thermal energy utilization and radiative day-time cooling, (2) windows that harvest radiant infrared radiation, and (3) thermal energy storage materials that store sensible heat, latent heat, or the heat of adsorption to subsequently be used to provide building heating, cooling, or power generation.

Nima Tabatabaei, PhD

Associate Professor

Research:

The focus of HBO Lab is on the design and development of thermal and optical imaging technologies and devices with applications in medical diagnosis and screening. Optics-based medical devices are of particular interest to us due to their intrinsic ability of revealing malignancies in their early stages. The early diagnosis of diseases improves the effectiveness of treatments, promotes prevention rather than medical intervention, and is probably the only approach for us to win the war on cancer.

One of the major challenges in optical imaging of endogenous tissue contrast is the poor specificity due to background signals from the healthy tissue. The HBO Lab’s vision is to overcome this shortcoming by separating excitation and detection channels (i.e, Hybrid methods). In this scenario, crosstalk between the channels takes place by energy conversion at malignant sites that are sensitive to the excitation.
