BIOGRAPHY

A passionate PhD researcher on solar-driven green hydrogen generation for carbon neutrality at Kyung Hee University under the supervision of Professor Jung-Ho Yun. Have a very high interest in Z-/S-scheme heterojunction photo/electro-catalysts for Hydrogen Evolution Reaction (HER), Oxygen Evolution Reaction (OER), Waste-water treatment, CO2 reduction, N2 reduction reaction (NRR-NH3), and so on.

Originally from Chin State, Myanmar based currently on South Korea. She grew up in a very lovely and warm family. Moreover, she is blessed to be able to join A2EN Lab under the brilliant guidance of Professor Jung-Ho Yun and her caring lab-mates. She is also grateful to her previous (Master research journey) supervisor Professor Dong Kyoung Lee and her previous lab-mates. Last but not least, she loves Jesus Christ so much that she continues to set an example as a faithful Christian in her life journey especially in her research journey.
