Biostatistics Faculty Research

Methods

Analysis of Sample Surveys

Data on national health and epidemiology are often collected using complex probability sample designs involving stratification and clustering of units.

Bayesian Statistics

Enabled by computational advances such as Markov chain Monte Carlo methods since late 1980s, Bayesian modeling and analysis are increasingly adopted in biomedical, public health and general data science research.

Computational Statistics

Today, nearly every statistical analysis is performed on a computer. Some methods are particularly dependent on intensive computing or custom software. Biostatistics faculty are involved with this specialty, known as computational statistics.

Longitudinal and Correlated Data

Correlated data are common in many health sciences studies, where clustered, hierarchical, non-independent, and spatial data are frequently observed.

Nonparametric and Semiparametric Modeling

In contrast to parametric modeling, where the distribution of the data is assumed known up to a finite-dimensional parameter, nonparametric methods involve an infinite dimensional parameter.

 

Statistical Analysis with Missing Data

Empirical studies in the social, behavioral, economic, and medical sciences frequently suffer from missing data.

 

Survival Analysis

In many medical and scientific studies, investigators are interested in analyzing data on time to an event. Applications of this work arise in areas as diverse as medicine, epidemiology, demography, and engineering.

 


 Applications

Bioinformatics

Biomedical research is undergoing a major revolution as novel experimental approaches are yielding unprecedented amounts of data.

 

Brain Imaging

Recent advances in medical imaging technology allow the measurement of brain activity of the intact, living human brain.

 

Cancer

Many Biostatistics faculty and students are actively involved in a broad spectrum of cancer research projects and in developing statistical methodology motivated by cancer research.

Clinical Trial

Clinical trial research involves the study of novel therapies in patients with the goal of identifying the best possible treatment.

 

Endocrinology

Endocrinology is loosely defined as the study of hormone secretion and the action of hormones on their target cells.

Epidemiology and Public Health

Faculty and students are actively involved in a broad spectrum of methodological and collaborative research in Epidemiology, Health Behavior and Health Education, Environmental Health, and Health Policy and Management.

 

Genetics

Driven by advances in array based and sequencing based technology, the Human Genome Project, International HapMap Project, the 1,000 Genomes Project, and various forms of genome-wide association studies, genetics is taking an ever-more-central role in all the biomedical sciences.

Genomics

Genomics uses a combination of recombinant DNA, DNA sequencing methods, and bioinformatics to sequence, assemble, and analyse the structure and function of genomes.

 

Organ Failure and Transplantation

There are more than 300,000 people alive today in the U.S. because they are receiving ongoing replacement treatment for their failed kidneys, hearts, livers, or other organs.
