I am a PhD researcher working under the supervision of Prof. Caterina Ducati and a member of Downing College. Prior to Cambridge, I received my B.Eng. with Honours in Materials Science and Engineering from the National University of Singapore. My research is focused on applying analytical SEM and TEM to study the properties, stability, and upscaling of perovskite solar cells. Beyond day-to-day research, I mentor prospective Indonesian graduate students through the Indonesia Mengglobal Mentorship Program. I also taught Materials Science IB supervision classes for Trinity College from 2018 to 2020.

My research is funded by the Jardine FoundationCambridge Trust, and ESTEEM3, an EU Horizon 2020 program.
