I completed my PhD since 2019. I also spent great time at Siemens Research and Facebook AI Research (FAIR). My PhD research focus was computer vision and deep learning, especially their applicaitons in medical imaging and healthcare.

I am working on machine learning and computer vision research at Google.

I am actively looking for self-motivated interns to explore advanced research topics (e.g. data efficient learning). Contact me if you are a good fit.
