Lu Yuhuan (路玉欢)

I am a Research Fellow at Harvard Medical School and Boston Children’s Hospital, working with Dr. Davood Karimi.

From September 2020 to September 2025, I am pursuing my Ph.D. at Hunan University under Prof. Kenli Li and Prof. Ningbo Zhu.

from September 2023 to September 2024, I was a visiting Ph.D. student at Nanyang Technological University with Prof. Jagath Rajapakse.

I received my B.Eng. in Computer Science and Technology from Hunan University, and since 2019 my research has focused on medical image analysis and fetal ultrasound.

Research

I’m interested in medical image analysis, ultrasound image processing, fetal cardiac video analysis.
