Students in WPI’s PhD in statistics program tackle the deeper problems in statistics and apply them to real-world applications in academic settings and in industries as diverse as banking and healthcare.


As the need for skilled statisticians increases, WPI’s PhD in statistics program offers a rigorous plan for students who enjoy the field’s challenges, who want to forge new paths, and who anticipate solving original problems. The program offers advanced coursework and research in statistics while imparting critical-thinking and problem-solving skills.

Students in this interdisciplinary program work closely with accessible faculty and often collaborate with researchers in data science, bioinformatics and computational biology, engineering, and business. Students demonstrate their competency at gathering vast amounts of numerical facts (data), evaluating it, and translating or presenting the findings and results for applications in various fields.

The knowledge gained in this program provides real-world opportunities for careers in data-driven industries. Companies use enormous amounts of data to help develop more targeted products. The healthcare industry has great need for statisticians who can help develop new drug technologies or conduct clinical trials. Students are supported in research that will solve puzzles and patterns in big data.

Faculty Profiles

Faculty members include the following:

Zheyang  Wu

Zheyang Wu

Associate Professor

Professor Wu's research interest lies in applying the power of statistical science to promote biomedical researches. In statistical genetics, he is developing novel statistical theory and methodology to analyze genome-wide association (GWA) data and deep (re)sequencing data to hunt new genetic factors for complex human diseases. In epigenetics, he is studying gene expression regulation mechanisms through chromatin interaction, and RNA silencing pathways in the developmental stages of germ-line cells.

Frank  Zou

Jian Zou

Associate Professor-Mathematical Science

Professor Zou's research focuses on financial time series and spatial statistics with applications to epidemiology, public health and climate change. His most recent research on statistical theory and methodology addressed a wide range of challenges including high dimensionality, complex dependencies, and space and time variations. His research in high-frequency financial data tackled problems with high dimensionality, which is currently a hot topic in statistics.

Buddika  Peiris

Buddika Peiris

Assistant Teaching Professor-Mathematical Science

Teaching is an art. It is something you develop within yourself. It needs hard work, time, creativity and dedication. Giving clear and understandable lectures, facilitating group activities, and interacting with students are all important parts of my teaching. My objectives as a statistics educator are: (1) to teach students about statistical tools and how to use them correctly, (2) to expose students to the structure of statistical analysis, and (3) to teach students how to communicate statistical results and concepts to a variety of audiences.
