My research interests focus on materials for optoelectronic technologies, such as light-emitting diodes (LEDs) and next-generation solar cells. For the past 11 years, I have studied semiconductor thin-film, organic, and inorganic perovskite LEDs and solar cell fabrications, and I have published more than 10 peer-reviewed articles (Google Scholar). My research team conducts active research using a Mbruan glove box, spin coaters, and Characterization instruments located at Hope College to study the chemical composition characterization of thin films and active layers, degradation mechanisms, and internal and external stability studies of perovskite-based LEDs and solar cells. Below is the list of my current research.

1) Fabrication and experimental investigation of semiconductor thin-films and perovskite active layers
2) Degradation, stability, and reliability for optoelectronic devices
3) Next-generation, large-area, and flexible optoelectronic devices
