🙋🏻‍♀️ About Me

I am currently a PhD student at Monash University, supervised by Prof. Jianfei Cai and Dr. Yasmeen George. Prior to joining Monash, I received my Master’s and Bachelor’s degrees from Northwestern Polytechnical University, where I was advised by Prof. Yong Xia and Assoc. Prof. Hengfei Cui. My recent research focuses on trustworthy medical image analysis.
