I am a software engineer at Google. As a machine learning engineer and researcher, I am interested in Responsible & Safe AI development for large models, especially building fair and robust AI frameworks that do not have demographic disparities and generalize well in new data distributions.
Before joining Google, I completed my Ph.D. in 2024 from KAIST EE and was extremely fortunate to have been advised by Prof. Steven Euijong Whang during my PhD journey. I am also a recipient of the Microsoft Research PhD Fellowship. Previously, I worked as a research intern at Google DeepMind & YouTube in 2023 and NVIDIA Research in 2022, working with wonderful mentors.
