Ho research group focuses on Sustainable Smart Solar Systems (S⁴) which play important roles in renewable energy and water supplies, as well as autonomous control and monitoring for clean, smart and liveable cities. The three solar thematic thrusts are solar catalysis, solar water and solar mechatronics. Her research group aims to study the next generation nanostructured materials by harnessing their unique physical and chemical properties that will impact electronics, energy, healthcare and robotics. The group’s approach is multidisciplinary, which involves concepts from electrical engineering, chemical engineering, materials science to physics.
