I'm an AI researcher focused on building algorithms and tools aiming to advance healthcare through technology. I'm currently a PhD student at the University of Toronto, advised by Dr. Chris McIntosh and Dr. Michael Brudno where my research revolves around developing algorithms that address biases in AI models applied to medical data. A very special shoutout to the Vector Institute, University Health Network (UHN) and SickKids Hospital for generously supporting my work and and placing me in an environment of world-class researchers and clinicians.
I completed my Masters from the National University of Singapore (NUS), specializing in Computational Intelligence. Before joining the PhD program, I worked as an AI Engineer developing IP and building tools for AI augmented healthcare applications.
I love the sea, and I'm a certified scuba diver. P.S : If you ever need company to dive, drop me a message. Thanks to long layovers and commutes, I've been managing to read a bit. Here's my reading list if you are thinking "hmm, what should I read next?"
My primary research focus is on identifying and combating data biases and the phenomenon of shortcut learning in AI/healthcare models. I'm interested in building debiasing techniques for healthcare tasks. I'm interested in putting together new healthcare datasets (especially from developing nations) and building systems that improve healthcare pipelines and enable a more equitable utilization of AI tools.
I'm also interested in putting my engineering and research skills to use. If you have tasks which have a large amount of unlabelled data, please reach out. I have some expreience with semi-supervised algorithms and building human in loop AI augment annotation pipelines.
On the other end of the spectrum, if you have very little data, I'm interested in utilizing generative models for data augmentation and generation.
