Research Interests

My research focuses on developing hybrid organic-inorganic semiconductors with precisely engineered heterostructures for the future of energy-conversion technologies. Currently, my group is working on 1) broadening the scope of hybrid heterostructures by systematically designing semiconductor combinations and employing advanced interface engineering, 2) gaining deeper insights into molecular and nanoscale interfacial properties through cutting-edge spectroscopic techniques, and 3) leveraging these advancements to produce energy-efficient optoelectronic devices, contributing to the global energy transition.
