Yuning Li
Lecturer in Accounting and Finance



Dr Yuning Li is a Lecturer in Accounting and Finance, joining the School for Business and Society in September 2023. Before that, he received his BSc in Mathematics and PhD in Statistics from Zhejiang University and his PhD in Economics from University of York.



My research interests are:

  • Financial econometrics: Time series model, Market microstructure, and High-frequency data analysis
  • Statistical modelling: Nonparametric estimation, Change point detection, and High- dimensional data analysis

My research is theoretically and computationally intensive, mainly in high-dimensional/big data analysis and financial data analysis, which involves development of innovative statistical models, simulation, asymptotic analysis and estimation.

My current research mainly focuses on the latent factor model, which has emerged as a powerful framework for analysing high-dimensional data. By assuming that the observed variables can be expressed as linear combinations of a few latent factors plus an approximation error, the factor model provides a means of dimension reduction, captures the essential dynamics of the data, and
can be applied in many areas such as portfolio management.
