RESEARCH: Our research focuses on the following areas
   
  • Data privacy and differential privacy
  • Statistical learning and machine learning
  • Regularization techniques for empirical risk minimization in complex and large models
    such as deep neural networks and graphical models
  • Bayesian methods and modelling
  • Statistical analysis of missing data
  • Epidemiological, biostatistical, and social science applications
with the joint efforts from a group of hard-working people:
   


PI Fang Liu, Ph.D.
Associate Professor & Director of Graduate Studies
Prof Liu joined Notre Dame and the ACMS in the fall of 2011 as an assistant professor. Her statistical methodological work focuses on data privacy, Bayesian methods and modelling, and statistical learning and machine learning (refer to  for her publications). Dr. Liu is funded as PI on 3 NSF grants on differential privacy theory, methods and applications. In addition, she serves as the lead statistician on a Gates Foundation funded project (Click here for an introduction of the research program) and a UNITAID-funded project (Click here for the Press Release) to assess the efficacy of promising malaria control methods, and the Notre Dame liaison on the Design and Biostatistics Program in the Indiana Clinical and Translational Sciences Institute to provide investigators centralized access to the biostatistics and bioinformatics programs among several Indiana research universities (ND, Purdue, IUPUI, IU-Bloomington). Prof Liu's works is/was supported by
