Lingyu Du I earned my Ph.D. in Computer Science from Delft University of Technology, the Netherlands, in April 2026, under the supervision of Prof. Guohao Lan and Prof. Koen Langendoen. I obtained my Master’s and Bachelor’s degrees (Honors Program) in Control Science and Engineering from Harbin Institute of Technology, Harbin, China, in 2021 and 2019, respectively. My research lies in the intersection of pervasive systems and machine learning, with a focus on enhancing efficiency and trustworthiness of machine learning systems and developing human-centered applications.
