Arizona State University enables my research in thermal radiation and optical experiments, where I lead a project focused on continuous power generation using self-adaptive vanadium dioxide coatings integrated with thermoelectric generators. My work includes optical characterization, thin film fabrication, heat transfer modeling and validation utilizing advanced technologies to achieve significant temperature modulation.
My PhD in Mechanical Engineering from the University of North Texas underpins my expertise in optimizing resonant gratings through computational methods like neural networks, Bayesian optimization and genetic algorithms. I am motivated by opportunities to advance sustainable energy solutions and contribute to cutting-edge optical and thermal engineering innovations.
