About Me

Resume
    Welcome! I'm currently pursuing my second master’s degree in Computer Science at the Courant Institute of New York University, with concentration in ML and Computer Vision. Broadly, my research interests lie in deep learning, self-supervised learning, and other machine learning application to tackle real-world problems.
     
    Recently my work focuses on (1) self-supervised learning, (2) multimodal model, and (3) distributed ML system.
     
    In my free time, I enjoy playing soccer as a striker. I also enjoy skiing, espresso-making, and most importantly, spending time with my two adorable but sometimes stubborn Japanese Akitas - Kohana and Mochi.

 

Most Recent Update

Due to current economic conditions, my offer at Amazon will not be extended and I am now actively looking for full-time position in ML/AL in US and Canada after graduation (expected May 2023).
