I was born and spent my wonderful childhood in Penang, a small island at the northern Malaysia. After finished my pre-university, I enrolled to the National University of Singapore (NUS) for my undergraduate studies in 2001, majoring in Physics.

After completed my bachelor degree, I pursue a MSc in NUS physics department, working on canonical and loop gravity under Professor. Kuldip Singh. After that, I spent one year at the Centre for Quantum Technologies (CQT) as research assistant and worked on quantum information theory.

In 2014 I graduated with PhD from NUS, working under Dr. Parwani on the deformed quantum mechanics and quantum gravity phenomenology. Before joining SUTD in 2019, I was teaching track Physics instructor in NUS physics department.
