Biography

I am currently a Principal Researcher in Applied Sciences Group at Microsoft, Redmond. I earned my PhD in Applied Mathematics and Statistics from Johns Hopkins University (JHU) in 2021, where I was advised by Dr. Daniel P. Robinson and Dr. René Vidal. Prior to my PhD, I received my Master's degrees in Computer Science and Financial Mathematics from JHU in 2020 and 2016, respectively. I began my academic journey with a Bachelor's degree in Mathematics from Sun Yat-sen University in 2014.

Throughout my career, I have focused on improving efficiency in machine learning and artificial intelligence, especially in areas like computer vision and generative models. I am constantly seeking new ways to push the boundaries of these fields and make contributions to the world of applied science.

I would appreciate Anyverse Anonymous Feedback from anyone on anything. Feel free to ping me!
