Associate Professor
Research Areas: Experimental fluid dynamics, turbulence, turbulent boundary layer, transition, flow control
Laboratory: https://rhanson.lab.yorku.ca/
Email: hansonre@yorku.caProf. Hanson’s research takes a primarily experimental approach to the study of flow physics. He established the Fluid Mechanics and Flow Control Research Laboratory with a cornerstone closed loop wind tunnel and towing tank facilities. His group is focused on wall-bounded and separated flow phenomena with relevance to aerospace and sport-based applications. This builds from parallel focus on flow dynamics and instabilities as precursor to their control, which forms a close nexus with development of technology (active/passive) to enable favorable alteration of boundary layers, wakes and turbulence. Another branch of his research relates to aerodynamic characteristics of airborne pollutant.

Nima Tabatabaei, PhD
Associate Professor
Laboratory: Hybrid Biomedical Optics Lab
Email: nima.tabatabaei@lassonde.yorku.caThe 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.

With a current focus on solar thermal technology, our research spans the fields of thermal science, optics, and materials to develop new pathways and devices for transforming sunlight into useful forms, including electricity, heat, clean water, and renewable fuels. Our research also touches on complementary fields including energy storage, advanced thermal insulation materials, and advanced thermal characterization techniques.
Our three main research thrust areas are: solar concentrators; solar absorber materials; and solar thermal desalination devices. Through theoretical analysis, numerical simulation, and experimentation, we aim to advance the fundamental knowledge in these areas to strive towards more efficient and cost-effective solar thermal systems. Our contributions in these areas are underpinned by specialization in nonimaging optics, optical properties measurement, heat transfer, and thermodynamics of photothermal and thermochemical processes.
