Dr. Ryckman’s research interests lie in the development and application of photonic platforms to solve problems in areas of sensing, biomedicine, food-safety, and computing/communications. Some specific topics of study include: integrated optical devices and passives, visible/IR wavelength integrated optics and sensors, photonic nanocavities, novel nano-fabrication techniques, spatial-mode and diffraction phenomena, ultra-high surface area nano-materials, and opto-electronic devices for trace-level biosensing.
