About

Longtail boat in Thailand

I am Alex Hung (孔令宇), a ph.D. student in the Computer Science department at UCLA working in Sung Lab where I am fortunate to be advised by Prof. Kyung Hyun Sung and Prof. Demetri Terzopoulos. Prior to joining UCLA, I was working in Biomedical Image Guidance Lab at CMU as a Master student under prof. John Galeotti. Before graduate study, I received my Bachelor’s degree in Biomedical Engineering from Peking University where I worked with Prof. Tianyu Xie and also minored in Computer Science. During undergrad, I also briefly worked in Penn Image Computing and Science Lab at UPenn under the supervision of Prof. Paul Yushkevich.

My main research interest is to apply computer vision and machine learning approaches to medical image analysis. In particular, I am interested in medical image segmentation, uncertainty measurement, and image generation.
