Research Interests
Dr. Hu's statistical research has primarily been in methodological development for
handling data with complex structures. Her contributions in the area include
pseudo-likelihood based and estimating function approaches with supplementary
information. Growing from her early
work on incomplete event history data, such as censored/truncated lifetimes and panel
counts, Dr. Hu's current interests are in various unconventional point process
data. Her on-going projects include analyses of longitudinal data with latent classes and
marked point processes with spatial correlations.
Dr. Hu has collaborated with investigators from a variety of research fields,
including HIV/AIDS, cancer, public health, reliability,
forest fire management, psychology, political sciences, sports analytics,
and substance use disorder.
She enjoys identifying statistical problems from real-life projects and
developing approaches to dealing with the challenges.

Brief Biography
Dr. Hu received her PhD in statistics at University of Waterloo under the
supervision of Jerry Lawless. Following her research experiences
at Health Canada and Harvard School of Public Health, she was on the faculty
at University of Memphis and an adjunct faculty member
at St. Jude Children's Research Hospital.
Dr. Hu joined Department of Statistics and Actuarial Sciences at Simon Fraser
University in 2003, and is now a Professor of Statistics. She has taught
courses at all the levels at SFU, and participated in the development of
the biostatistics-related courses of the department.
Dr. Hu obtained an NSERC Discovery Accelerator Supplements (DAS) (2016-2019),
an NSERC University Faculty Award (2003-2008), the Frank Wilcoxon Prize of
1998 (jointly with JF Lawless and K Suzuki), and the Pierre Robillard Award of 1996.
She is an American Statistical Association
(ASA) fellow and an elected International Statistical Institute (ISI)
member.
Dr. Hu is an Associate Editor
of Canadian Journal of Statistics (2022-present) and
Lifetime Data Analysis (2020-present).
She was an Editor-in-Chief of
Statistics
in Biosciences (2021-2023), and served on the editorial
boards of
Canadian Journal of Statistics (2010-2012),
Lifetime Data Analysis (2010-2017),
Statistical Papers (2011-2016), and Statistics in
Biosciences (2009-2020).
