A. Personal Statement
I have a broad background in biostatistics, with specific training and expertise in longitudinal data analysis and
study design, Bayesian adaptive clinical trial design, Bayesian nonparametrics, missing data methods, and
mediation analysis. I have served as a co-investigator or primary statistician on over 30 NIH-funded grants in
behavioral science, health disparities research, and clinical trials, including as director of the biostatistics and
data management core of a P60 Center of Excellence Grant, and a key statistical collaborator in a Stand Up
To Cancer Dream Team Translational Research Grant. I have overseen the statistical design, conduct and
analysis, and assisted in the interpretation of analysis results and preparation of manuscripts, in all these
collaborative projects.

C. Contributions to Science
1. The uniform shrinkage priors (USPs) for the random-effect variance or covariance matrix in Bayesian linear
or generalized linear mixed models were developed in 1999 and 2000. This approach provided an
excellent alternative to the commonly used diffuse proper priors, which are known to have issues of
posterior near-impropriety and sensitivity of the inference to the prior specification. Despite the satisfactory
performance of the USPs, this approach has not been widely used because it was only developed for
simple two-stage hierarchical models, due to both conceptual and technical difficulties in extending the
method to more general hierarchical models. I extended the definition of the USP to semiparametric mixedeffects models and showed desirable properties of the new prior both analytically and empirically via
simulations. Further extension of this prior specification in a general class of mixed-effects models is
currently underway. In all the work, I developed the original idea of the extension and carried out most of
the modeling and implementation work that has led to the publication of the following paper.
a. Li Y, Lin X, Müller P. Bayesian inference in semiparametric mixed models for longitudinal data.
Biometrics 2010; 66(1), 70-78. PMID: 16984320. PMCID: PMC3081790.
2. Nonparametric modeling of an unknown distribution, in particular, using the Dirichlet process prior, is at the
center of robust inferences in Bayesian hierarchical models. When this approach is used in random-effects
model, an identifiability issue arises which, if not addressed, will result in incorrect and seriously misleading
inferences for the fixed effects that are often of scientific interest. I formally pointed out the issue and
proposed a simple yet effective adjustment to inference based on analytic evaluation of the posterior
moments of the fixed effects that addressed the identifiability issue. This work has solved a long-standing
identifiability problem in nonparametric Bayesian inference using the Dirichlet process prior, thus allowing
its wide use for valid inferences in Bayesian hierarchical models.
a. Li Y, Müller P, Lin X. Center-adjusted inference for a nonparametric Bayesian random effect
distribution. Statistica Sinica 2011; 21(3), 1201-1223. PMCID: PMC3870168.
3. Dose finding and dose-schedule finding are critical early steps in the development of drugs that treat
cancer. Along with colleagues, I have developed efficient and robust designs for dose-finding and dose-
schedule-finding trials that have improved the drug development process. Examples of our proposed
designs include the modified toxicity probability interval-based designs, which have been routinely used by
practitioners including major pharmaceutical companies in their dose-finding trials. I have also mentored
trainees (marked by a * below) in developing other novel and efficient designs for dose- and doseschedule-finding trials.

isotonic transformation. Statistics in Medicine 2008; 27(24), 4895-4913. PMCID: PMC4562497.

Royal Statistical Society, Series C 2016; 65(2):259-272. PMCID: PMC4747255.
4. Along with colleagues, I have developed missing data methods, in particular, nonparametric multiple
imputation methods for ignorable missing data. These methods are widely applicable in biomedical studies,
where missing data commonly arise.
