Chai Muh Chyi
I was born and raised in Malaysia. I am agile, effervescent, and adventurous. As an individual and a scientist on earth, I believe in challenging the norm and embracing the unknown. It empowers me to keep trying after countless failures, with only one goal in mind, to create a different and better future for others and myself.
Background and career
I was first exposed to scientific research in my final year of undergraduate studies in Malaysia. My first research topic was on nitrogen fixation bacteria. For my master's degree, I studied the survival mechanism of Burkholderia pseudomallei, a human pathogen and biothreat agent that causes melioidosis. The first part of my doctoral studies was on cortical development in mammals that included my first attempt at making cortex in a dish. Mesmerized by the potential of in vitro modeling, I started modeling brain diseases, which constitutes the second part of my doctoral studies.
For my postdoctoral studies with Keio University Global Research Institute (KGRI)/Laboratory of Physiology, Keio University School of Medicine, I have established various cellular models rare pediatric diseases and neurodegenerative diseases, including Parkinson's disease. By utilizing these models and exploiting the capacity of high-throughput next-generation technologies, I seek to decode the molecular basis of rare brain diseases.
