Research Areas: Data Analytics, Machine Learning, and Deep Learning

Yan Zheng, Visa Research scientist.

Biography

Dr. Yan Zheng joined Visa Research as a Staff Research Scientist in 2017, and was promoted to Sr. Staff Research Scientist in March 2019. Prior to joining Visa, Yan was a Research Assistant at the University of Utah, and a Research Intern at Visa Research. Yan received her Ph.D. in Computer Science from the University of Utah in 2017, and a B.S. in Computer Science from Nankai University. Her Ph.D. thesis titled, “Algorithms and Coresets for Large Scale kernel Smoothing,” focused on algorithms for dealing with large-scale kernel smoothing problem, including kernel density estimate and kernel regression.

As a member of the Data Analytics team, her research interests are in deep learning and large-scale data analytics, in particular data mining, databases and machine learning. Dr. Zheng regularly serves on the program committee of data mining conferences and has published 13 papers in several international conferences and journals, including Virtual Dedicated Server (VDS), Knowledge Discovery and Data Mining (KDD), Association for Computing Machinery's (ACM) Special Interest Group on Management of Data (SIGMOD), and many more.
