Congratulations to Tian Chen, recipient of the inaugural award of the William Jackson Hall Graduate Student Fellowship. Tian’s statistical methodological research focuses on modern variable section methods, mixture models, rank regression and integrations of all these models within a unified framework built upon the Functional Response Models (FRM), a paradigm for modeling between- and within-subject attributes, rather than the within-subject attributes only as in standard regression models. Her work has significant applications, especially in the Big Data era where dealing with between-subject attributes and an excessive number of variables is the norm, rather than the exception.

On Saturday, November 1, 2014, the Department hosted an Open House for prospective graduate students. This event provided students potentially interested in graduate study in biostatistics and statistics with an opportunity to learn about our programs, to meet with current students, faculty, and program alumni, and to gain some perspective on the many career opportunities this exciting field has to offer. Thank you to all faculty, students and staff who contributed to the success of our first open house!

October 2013

Human interactions via internet and mobile apps are increasing and ubiquitous among all walks of life. We stand on the cusp of a new opportunity due to: improvements in computing, the rapidly growing ubiquity of smart environments, and a resulting duality in contemporary society, that is, the norm of living simultaneously within virtual as well as geophysical proximal interactions and community contexts. Supported by the National Institute of General Medical Sciences in response to a joint call for Big Data proposals by the National Science Foundation and the National Institute of Health, a multidisciplinary team with PIs Hua He and Naiji Lu from the Department of Biostatistics and Computational Biology and Ann Marie White from the Department of Psychiatric will lead a three-year investigation on modeling the human interactions and their impacts on health and health related behavioral outcomes, along with several other investigators from these departments and the Department of Computer Science at both the University of Rochester and the Rochester Institute of Technology as well as local community leaders. They will be developing new methods to address flaws in conventional statistical models for such between-subject attributes and integrate such information when modeling traditional individual behavioral and health outcomes, or within-subject attributes and associated social dynamics. Their research will greatly facilitate intervention and prevention research in the Big Data era, as more disciplines and research studies embrace the new opportunities afforded by this scientific revolution.

Congratulations to Katie Evans, who successfully defended her PhD thesis, "Extensions to Model-Based Clustering for Mixed-Type Data: A new model framework, variable selection, and outlier identification", on October 18, 2013. Katie's advisors are Drs. Tanzy Love and Sally Thurston.

September 2013

Congratulations to Dr. Chris Beck, who was selected as the 2013 recipient of the Outstanding Graduate Student Teacher Award, presented at the School of Medicine and Dentistry Convocation, September 12, 2013. The selection of the awardee is based on the instructor’s record of excellence in classroom instruction, as reflected by the letter of nomination from students enrolled in one or more courses in which the teacher has delivered a significant number of lectures and by course-instructor survey evaluations.

We welcome Dr. Tong Tong Wu, who joined the Department in September 2013 as Associate Professor. Dr. Wu received her PhD in Biostatistics from the Department of Biostatistics, UCLA School of Public Health in 2006. Prior positions include postdoctoral researcher in the Department of Human Genetics, UCLA and Assistant Professor in the Department of Epidemiology and Biostatistics at the University of Maryland, College Park in 2007. Dr. Wu is a biostatistician with interests in high-dimensional data analysis; survival analysis; machine learning; computational statistics; computational biology and statistical genetics; and longitudinal data analysis.

Postdoctoral fellow Matthew McCall has been awarded a K99 grant from the National Human Genome Research Institute to develop the statistical methodology necessary to estimate gene regulatory networks. Estimation of these networks is crucial to understanding cellular mechanisms, detecting differences between cell types, and predicting cellular response to interventions. Dr. McCall’s goal is to further our understanding of complex cellular networks by drawing on the fields of statistics, systems biology, and genetics. Dr. McCall's advisor is Dr. Anthony Almudevar.

Fourth-year graduate student Jason Morrissette and his advisor, Michael P. McDermott, PhD, published a paper in the September issue of the Journal of the American Statistical Association entitled “Estimation and Inference Concerning Ordered Means in Analysis of Covariance Models with Interactions”. In the usual analysis of covariance model, when interactions between the grouping variable and covariates are present, group comparisons may be performed using the Johnson-Neyman technique which identifies ranges of the covariates for which the group means significantly differ. In this paper, methods for estimation and inference are extended to the case where the group means are assumed to satisfy an order restriction across all levels of interacting categorical covariates and across pre-specified ranges of interacting continuous covariates. This work is part of Jason Morrissette’s doctoral dissertation.

February 2013

The Agency for Healthcare Research and Quality (AHRQ) has awarded an R24 grant to a research team led by Dr. Dongwen Wang. This project will tackle the challenging issue of disseminating evidence-based clinical practice guidelines to HIV healthcare providers through integrating various information technologies and social organizational contexts. Dr. Wang and his collaborator Dr. Amneris Luque, an HIV specialist from the Infectious Diseases Unit, have been working in this area for the past seven years and accumulated significant experience and resources. In particular, they have developed an online clinical education program sponsored by the New York State Department of Health HIV Clinical Education Initiative (CEI), and been engaging in dissemination of HIV clinical knowledge with online CME/CNE courses, multimedia learning modules, interactive case simulation tools, and mobile training resources. Serving in dual roles as the Technology Center and the Resource & Referral Center for the CEI program, their team has been collaborating with five other CEI Centers in New York State to disseminate the latest findings from HIV clinical research to frontline healthcare providers. Since its launch in 2008, the CEI online education program has reached out to 31,000 individuals from all 50 U.S. States and 160 countries around the world. Clinicians have completed online training through this program and acquired 2,100 CME/CNE credits. The CEI website ( has recorded 64,000 visits and 278,000 pageviews, and is now consistently ranked by Google and other search engines as a top site for HIV clinical education.  This newly funded three-year $900,000 grant from AHRQ will significantly enhance the existing program through developing partnerships, conducting multi-disciplinary dissemination research, building an online repository of HIV/AIDS information products, and evaluating the usability of program resources and their impacts to knowledge translation. Other members of the research team are Terry Doll, Matt Bernhardt, Hung Le, Tom DellaPorta, Monica Barbosu, and Keith Bourgeois.
