Theme 1. Condensed-phase organics/conjugated-polymers 

Functional molecules/conjugated-polymers with optical/electronic properties can reveal unique features or even offer new applications. We are interested in:
i) how photons convert to excitons/charged-carriers (electrons/holes) in this low-dielectric medium,
ii) how inter-/intra-molecular interactions and molecular packing can govern materials properties, using optical/microwave spectroscopic tools, and
iii) how we can obtain/modulate desired condensed-matter properties.

Theme 2. Organic/inorganic hybrid perovskites

Hybrid perovskites are a young class of semiconducting material with extraordinary optical and electrical properties. Their synthetic advantage of solution-processibility highlights further commercialization. We aim to understand their optical/electrical properties, carrier dynamics and their relationship with structural components (surface, various defects, etc.)

[Laser spectroscopy]

To observe and understand various photophysical/chemical phenomena, our group utilizes several state-of-the-art spectroscopic methods, such as transient absorption (TA) spectroscopy and flash-photolysis time-resolved microwave conductivity (FP-TRMC)
