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.

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.
