NINDS awards $1.925 million grant to Drs. Matthew McCall and Sally Thurston to develop statistical methods for confocal microscopy images of microglia
March 2024
Microglia are immune cells that act as the primary first-responding sentinels in the brain. Although direct comparisons between microglia morphology and function are hard to make, it is clear that morphology changes in response to many diseases. Improved methods of microglia image processing and analysis are needed to directly link morphological changes with their corresponding functional consequences in models of many human disease processes. The National Institute of Neurological Disorders and Stroke (NINDS) will fund Drs. McCall and Thurston, as well as Dr. Ania Majewska, to develop statistical methods to model microglial morphology that fully leverage the wealth of information present in the imaging data and provide interpretable parameter estimates and corresponding measures of uncertainty. The overall goal of the proposed research is to develop statistical methodology that will lead to improved analysis of microglial images and uncover the changes in morphology that are most predictive of alterations in microglial function.
Dr. Ernesto Aparicio-Puerta receives $ 312,396 in funding through the prestigious Marie Sklodowska-Curie Postdoctoral Fellowship
February 2024
Postdoctoral associate Ernesto Aparicio-Puerta, hosted by the McCall group, has been awarded the European Commission’s highly competitive Marie Sklodowska-Curie Postdoctoral Global Fellowship. The selection process evaluates the applicant's merits as well as the scientific quality of the host laboratory and the proposed project.
Ernesto’s miRAQEL project aims to optimize several aspects of microRNA sequencing analysis to overcome the limitations of currently available methods. Changes in microRNA expression have been linked to numerous diseases so improving the estimation of microRNA levels has the potential to boost our understanding of their roles in health and disease. The fellowship provides additional funding to establish collaborations with other leading labs in the field including Michael Hackenberg’s group (University of Granada) who will host Ernesto for the last 12 moths of this fellowship.
Collaborative award from NSF to Dr. Norman-Haignere ($769,112) and ANR ($468,021) to Dr. Boubenec to study the neural computations of adaptive temporal integration in auditory cortex
January 2024
Deriving meaning from complex sounds such as speech and music requires the brain to flexibly integrate across multiple timescales, but relatively little is known about the neural mechanisms of adaptive temporal integration in the auditory cortex. This project uses electrophysiological recordings and computational modeling to understand the mechanisms of temporal integration in the ferret auditory cortex. The project will test whether the brain can adapt its integration window over short and long timescales depending on the duration of sound structures (e.g., words), and whether this flexibility depends on the types of sounds that one hears and their behavioral relevance. The study will leverage a new paradigm for studying temporal integration windows from nonlinear systems and computational encoding models derived from deep neural networks.
NIEHS awards $1.79 million grant to Drs. Ertefaie, Strawderman, and Dominici to study causal mechanisms by which air pollution affects the recurrence of cardiovascular events
December 2023
One of our era’s greatest scourges is air pollution, and it is well documented that exposure to fine particles (e.g., PM2.5) increases the risk of cardiovascular disease (CVD) and death. There remain two critical knowledge gaps. First, existing studies have mainly considered the occurrence of the first adverse health event as health outcomes; hence, the impact of overall disease burden and PM2.5 exposure on disease progression remains unknown. Second, there are no studies assessing the causal pathways by which exposure to air pollutants impacts recurrent cardiovascular events. This 3-year NIH grant, a joint effort involving MPIs from the University of Rochester and Harvard University, addresses these two critical gaps, the overarching goals being to elucidate (i) the impact of PM2.5 on the burden and progression of CVD; and, (ii) the key causal pathways by which air pollution exposure impacts such events. Accomplishing such goals will be facilitated by new analyses of an unprecedented data collection consisting of an already harmonized and linked Part A Medicare data (33+ million subjects 2000 to 2019) at both the individual and zip code levels.

One of Dr. Thurston's colleagues in Biostatistics also noted that a common theme in Dr. Thurston's work with students is her "selfless dedication and her amazing ability to inspire her mentees to believe in themselves."
NIDCR awards $3.5 million R01 grant to Drs. Xiao, Gill, and Wu to Predict Severe Childhood Tooth Decay in Early Infancy
June 2022
Although largely preventable, Early Childhood Caries (ECC)—severe tooth decay among young children—affects one third of socioeconomically disadvantaged and racial/ethnic minority preschool children in the U.S. While ECC is an infectious disease initiated by cariogenic pathogens, it is now understood to be a multifactorial and ecology-based disease, with the interplay between host, environment, and oral microbiota affecting the onset and severity of ECC. The Oral Microbiome in Early Infancy (OMEI) study will address the urgent need to understand biological factors related to pediatric dental caries among the low-income and racial/ethnic minority groups and develop caries prediction models adjusting multilevel factors.
The OMEI will be the first study to our knowledge to comprehensively evaluate the longitudinal development of early life oral microbiome and their relation to dental caries among low-income minority infants. The study results will build a foundation for developing early life salivary diagnostic tools to predict ECC and further prevent ECC by shaping an infant's oral microbiome and other related multilevel factors. Dr. Michael Sohn will contribute his expertise in metagenomics sequencing to this study. Learn more about this study.

NINDS awards $3.14 million grant to Drs. Ertefaie, McDermott, and Venuto to advance personalized medicine in Parkinson’s disease using harmonized multi-site clinical data.
October 2020
Parkinson’s disease (PD) manifests as a heterogeneous clinical syndrome and the variability in the clinical phenotype highlights the need to tailor the type and/or the dosage of treatment to the specific and changing needs of individuals. However, the relative lack of comparative evidence for different classes of drugs and the timing of their initiation has created challenges in devising recommendations to follow any specific therapeutic strategy. This two-phase study, funded by NINDS, will attempt to fill this important gap. The first phase (R61) focuses on creating a harmonized and curated data set by integrating data from six clinical trials and an observational study. In the second phase (R33), the harmonized data set will be leveraged to develop high quality individualized treatment strategies for PD with respect to several clinical outcomes. A robust marginal structural model will be developed that has better convergence properties than existing methods and leverages a non-parametric regression approach to mitigate the chance of misspecification of the nuisance parameters while providing valid inference (p-values and confidence intervals) for the parameters of interest.
NIGMS awards $1.97 million R01 grant to Dr. McCall to develop statistical methods for microRNA-sequencing experiments
September 2020
This grant aims to improve the analysis of microRNA-sequencing data by developing statistical methods that directly address the challenges unique to measuring expression levels of microRNAs. MicroRNAs are essential regulators of gene expression, alterations in which have been shown to disrupt entire cellular pathways, substantially contributing to a variety of human diseases such as heart disease and cancer. Despite their importance, our understanding of the role of microRNAs is hampered by a lack of statistical methods designed specifically to analyze microRNA-sequencing data. By developing such methods, this project will help us identify how changes in microRNA abundance contribute to many human disease processes. This grant provides additional funding for a long-term collaboration between Dr. McCall (URMC) and Dr. Halushka (JHMI).

NIDA awards $1.57 million R01 grant to Dr. Ertefaie to study the effect of partial treatment compliance in constructing individualized treatment strategies
March 2020
This grant aims to develop methodologies to adjust for partial compliance in constructing individualized treatment strategies using sequential multiple assignment randomized trials data. Existing tools that estimate the treatment effects using intention-to-treat analyses ignore information on patients’ compliance. The work to be done fills this important gap by providing a set of analytical tools that consider the noncompliance in the setting of sequential clinical decision making. Drs. Brent Johnson (URMC), Michael Kosorok (UNC-Chapel Hill), James McKay (UPenn) and Andrew Wilson (NYU) are co-investigators on this grant.
NIAAA awards $0.42 million R21 grant to Dr. Ertefaie to develop individualized treatment strategies for controlling alcohol use
March 2020
The overarching aim of this work is to address the need for robust, rigorous and efficient methods for estimating optimal treatment strategies in high-dimensional settings. Current methods for constructing individualized treatment strategies rely on certain modeling assumptions, and thus, the results can be very sensitive to the postulated models. The R21 aims to relax these unrealistic assumptions by leveraging the state-of-the-art nonparametric regression methods. Novel techniques for identifying key treatment effect modifiers from a large list of candidate variables are also to be developed. This work helps to pave the way for future studies that advance personalized medicine. Drs. Rob Strawderman (URMC) and James McKay (UPenn) are co-investigators on this grant.​
The Del Monte Institute awards a $50,000 grant to Dr. Ertefaie to study the comparative effectiveness of treatment strategies in Parkinson’s Disease
March 2020
Among neurological disorders, the fastest growing is now Parkinson's disease (PD), surpassing Alzheimer's disease. Existing guidelines for symptomatic drug therapy for PD can best be described as "permissive". The relative lack of comparative evidence for different classes of drugs has created challenges in devising recommendations to follow any specific therapeutic strategy; indeed, there remains substantial heterogeneity in the choice of treatment strategies. The proposal aims to fill this important gap. A specific goal is to use the data collected as part of the Parkinson’s Progression Markers Initiative (PPMI) study to identify a sequence of treatment decisions (drug classes) to optimize an outcome of interest; and construct a set of best treatment strategies. We will focus on motor complications, anxiety and depression scores measured at 3 and 24 months of treatment initiation as important clinical outcomes. Dr. Charles Venuto (URMC) is a co-investigator on this grant.
Drs. Rice, Strawderman and Johnson honored with award for "Best paper in Biometrics for 2018!"
January 2020
John Rice, a former postdoctoral fellow now at the University of Colorado School of Public Health, along with his co-mentors Rob Strawderman and Brent Johnson, were recently notified by the Editors of Biometrics, a premiere statistical methodology journal, that their paper, Regularity of a Renewal Process Estimated from Binary Data, was selected by a committee of current and former journal editors as the "Best Paper in Biometrics by an International Biometric Society (IBS) member" for the year 2018. The authors have been asked to present this work in a showcase session at the upcoming IBC meeting in July that will be held in Seoul, South Korea. The motivating example for this paper involves determining the effect of an intervention on the regularity of HIV self-testing behavior among at-risk individuals when exact self-testing times are not recorded. Assuming that these unobserved testing times follow a renewal process, the article develops suitable methods for estimation and inference for the renewal distribution parameters when only the presence or absence of at least one event per subject in each of several observation windows is recorded. The concept of "regularity" is also quantified and subsequently estimated by the coefficient of variation (CV) of the interevent time distribution. The paper applies these new methods to the data from the motivating example, concluding that the use of text message reminders significantly improves the regularity of self-testing, but not its frequency. The paper closes with a discussion on interesting directions for further research.
Roberta K. Courtman Revocable Trust awarded $50K to Drs. Zhang, Baran and Lin to study the brain connectomes of Supernormal older adults
January 2020
The objective of this project is to utilize the structural connectome to study the missing structural aspect in the “reserve vs. compensation” phenomenon to enrich the understanding of Supernormals’ cognitive superiority. Supernormals here refer to a group of old adults who have superior cognitive capacity with superior memory compared to their peers and even normal middle-aged adults. We suspect that, similar to their functional profile, Supernormals will have stronger structural reserve while relying on alternative structural compensation to resist amyloid-deposition and support cognitive function compared to typical agers. Ultimately, our long-term goal is to identify therapeutic targets that can resist AD pathophysiology or reduce AD pathophysiology’s adverse effect on cognition using knowledge gained from Supernormals.
NIMH awarded $0.75 million grant to Drs. Dunson and Zhang to study human brain structural connectivity
January 2020
NIMH has awarded $0.75 million grant to Drs. Dunson and Zhang to study human brain structural connectivity through the Collaborative Research in Computational Neuroscience (CRCNS) program. This project focuses on developing transformative methods for better characterizing and studying variability in human brain structural connection networks in relation to traits of the individual, including cognitive abilities and substance use. Diffusion magnetic resonance imaging (MRI) and structural MRI can be used to infer locations of millions of white matter fiber tracts acting as highways for neural activity and communication across the brain. The collection of interconnected fiber tracts is referred to as the brain connectome. Improvements in technology have enabled routine collection of high-resolution connectomes; however, there is a fundamental gap between state of the art in image acquisition and the tools available to reconstruct the connectome and study how connectomes vary across individuals in relation to individual characteristics. This project will enable substantial breakthroughs to close this gap by developing fundamentally new ways to process, represent, and analyze brain connectomes.

The joint Greater Data Science Cooperative Institute (GDSC) by UofR and Cornell funded by NSF
October 2019
The National Science Foundation (NSF) has awarded a three-year grant to establish a Greater Data Science Cooperative Institute (GDSC) jointly by the University of Rochester and Cornell University that combines shared expertise from electrical engineering, mathematics, statistics, and theoretical computer science.
The UR-Cornell GDSC is based on two founding tenets: that enduring advances in data science require combining techniques and viewpoints across electrical engineering, mathematics, statistics, and theoretical computer science; and, that data-science research must be grounded in an application domain. The following cross-disciplinary research directions are proposed: (i) Topological Data Analysis; (ii) Data Representation; (iii) Network & Graph Learning; (iv) Decisions, Control & Dynamic Learning; and, (v) Diverse & Complex Modalities. Additional cross-disciplinary research aims including the following are also integrated throughout these five research directions: combinatorial inference; multiple areas in machine and deep learning; and broadening machine learning with tools from signal processing, information & control theory.
The UR-Cornell GDSC specifically aims to consider applications in medicine and healthcare, an important application domain that represents a major strength of the UR, and one for which advances in data science can have a direct, positive impact on society.

Angela Branche and Edward Walsh (Co-Investigators in Infectious Diseases), supported by a new 5-year $3.8M NIH grant to reduce antibiotic overuse. The primary goal is to discriminate between bacterial and non-bacterial respiratory infection via high-dimensional gene expression profiling of blood. Such a diagnostic test would allow physicians to optimally manage patients with acute respiratory infections, which are a leading cause of antibiotic overuse and are linked to the rise of antibiotic resistant organisms. This grant builds upon prior research done as part of the NIH-funded Respiratory Pathogens Research Center (RPRC).

$1 million grant awarded to Drs. Lamberti, Weisman, and Strawderman
May 2018
The Laura and John Arnold Foundation has awarded a $1 million grant to the University of Rochester Medical Center to evaluate Minnesota’s replication of the successful Rochester Forensic Assertive Community Treatment (R-FACT) program.
The R-FACT program was created 25 years ago by J. Steven Lamberti, M.D. and Robert L. Weisman, D.O., professors in the URMC Department of Psychiatry, to address high rates of arrest and incarceration of people with mental illness. Two years ago, officials in St. Paul and Minneapolis requested URMC’s expertise and began recreating the R-FACT model in their communities.
R-FACT has shown that strong collaboration between mental health and criminal justice professionals provides mentally ill individuals with more effective interventions, and ultimately reduces rates of criminal convictions, jail time, and hospitalizations by roughly 50 percent while doubling time in treatment compared to other programs.
The $1 million grant will allow Lamberti, Weisman, and Robert L. Strawderman, Sc.D., professor and chair of the URMC Department of Biostatistics and Computational Biology, to evaluate the effectiveness of R-FACT in the Midwestern cities.
