Joshua Barback
Advisor: Jukka-Pekka Onnela
Joshuat was supported on this grant 2013-2014, 2015-2016, 2018-2019 and currently on a leave of absence. Joshua’s research interests focus on developing methods to utilize smartphone accelerometer data to understand human behavior.
Joshua’s work while appointed to this training program focused on digital phenotyping. In his project with the Onnela Lab at the Harvard Chan School he used the Beiwe research platform to collect raw sensor data from study participant smartphones. A primary goal was to leverage the data to develop refined behavioral phenotypes for social engagement, geographic mobility, physical activity, and characterization of an individual’s environment. The phenotypes were then used to inform his understanding of relevant domains including development and relapse of psychiatric disorders. In order to make best use of smartphone data, he required an assessment of device proximity in order to determine when a phone is being carried. This informs the investigator, for example, when GPS location coordinates actually correspond to the location of the owner. Joshua worked to develop an algorithm for proximity detection using pilot data from the HOPE study. He designed an additional study and collected data to validate this algorithm. He then used this algorithm to improve the methods for assessing geographic mobility which involved a novel combination of both GPS location data and accelerometer data. Past accelerometry-based studies of physical activity have found important insights by considering the durations of active and sedentary behavior. However, the missing data typical of smartphone accelerometry creates special problems when quantifying these durations. Joshua then worked on a project to address this problem using an imputation approach.
Tom Chen
Advisors: Rui Wang and Eric Tchetgen Tchetgen
Tom was supported on this grant from 2015 to 2018) received his Ph.D. in 2018. Dr. Chen’s dissertation was titled, “Robust Methods for Estimating the Intraclass Correlation Coefficient and for Analyzing Recurrent Event Data”. Tom is currently an Instructor at Harvard Medical School in the Department of Population Medicine at the Harvard Pilgrim Health Care Institute.
While appointed to the training grant, Tom’s research interests were clustered intervention trials, semiparametric theory, survival analysis, and stochastic approximation. He worked on five research projects. First, he proposed a doubly-robust semiparametric approach to estimating intraclass correlation in the presence of missing data and a fast-computational implementation for doing so. The second project proposed flexible estimation of random effects and error distributions for variance components models, providing nominal coverage for quantities such as the intraclass correlation coefficient (ICC). ICC is a key metric in exposure studies, as it measures the consistency of repeated exposure measures over time. This work also proposed a test of normality for random effects models and an agreement index based on the ICC. The third project, with fellow student Sam Tracy and Dr. Hajime Uno, posed the problem of highest density regions of survival confidence bands in an optimization framework & develops new confidence bands in this framework. The fourth project, conducted with student collaborator Yan Wang from the Department of Environmental Health at Harvard University, developed a method for estimating the components of the doubly-robust estimator using penalized spline techniques. The fifth project focused on an “evolving ring clustered randomized trial” for HIV prevention. Here, individuals were provided intervention based off their sexual contacts to HIV index cases. These individuals could refuse or drop-out in this study, and Tom developed a framework to account for these two types of missingness when estimating the cluster growth sizes from each index case. While not environmentally related, it allowed Tom to train in missing methods for network inference, a key area of research in many public health research areas.
Leah Comment
Advisor: Corwin Zigler
Leah received her Ph.D. in 2019. Leah’s dissertation was titled, “Bayesian Causal Inference with Intermediates”. Leah is now Director of Decision Sciences at Foundation Medicine, Inc
While appointed to this training grant, Leah’s research focused on methods for intermediate variables data (i.e., with mediation and principal stratification), which can elucidate causal pathways with a focus on facilitating better decision-making in the face of uncertainty. Previous research had looked at time-to- event outcomes subject to truncation by death, a problem that is sometimes referred to as semi-competing risks. Leah’s work introduced two new causal estimands, and described their application to policymaking, and individualized decision support. Because her estimation strategies are all rooted in the Bayesian framework, uncertainty quantification is naturally incorporated.
Irina Degtiar
Advisors: Francesca Dominici and Sherrie Rose
Irina received her Ph.D. in 2021. Dr. Degtiar’s dissertation was titled, “Generalizability Methods for Estimating Causal Population Effects”. She is now a statistician at Mathematica Policy Research, Inc.
While appointed to this training grant, Irina worked to compare a variety of causal effect estimators and then assessed the performance of different generalizability estimators that combine individual data across randomized and observational studies. She also completed a literature review of existing generalizability estimators that generalized results from randomized data, and ones that incorporated outcomes across randomized and observational studies. She continued that work and developed generalizability methods and built on machine learning algorithms to assess causal population effects. She compared a variety of causal effect estimators and assessed the performance of different generalizability estimators that combine individual data across randomized and observational studies.
Katrina Devick
Advisors: Brent Coull and Linda Valeri
Katrina received her Ph.D. in 2018. Dr. Devick’s dissertation was titled, “Nonparametric Regression
Methods for Causal Mediation Analysis”. She is currently a Research Associate at Mayo Clinic Arizona.
Research: While appointed to the training grant, Katrina’s research focused on developing new statistical methodology for causal mediation analysis and applying these methods to children’s environmental research. During the 2017-2018 academic year she worked on a project to quantify the impact of in utero exposure to a metal mixture (manganese, arsenic, and lead) on children’s neurodevelopment and to identify potential interventions on intermediate variables to block the harmful effect of the mixture. She also collaborated with postdoctoral fellows in Dr. Rosalind Wright’s group at Mt Sinai to develop generalized additive interaction models to estimate how the association between trauma and various outcomes in children is modified by maternal stress and child sex.
Eric Dunipace
Advisors: Lorenzo Trippa and Jose Zubizarreta
Eric received his Ph.D. in 2021. Eric’s dissertation was titled, “Optimal Transport Methods for Causal Inference, Multisample Testing, and Model Interpretation”. Eric is currently in medical school working towards his M.D at UCLA.
Research: While appointed to the training grant, Eric’s research focused on Bayesian model selection, Bayesian non-parametric methods, and causal inference. He worked with Dr. Trippa on a project that looked for ways to summarize posterior distributions that allow for sparsity to allow for 1) greater communication ease and 2) to allow for model selection should one choose. The goal was to apply this in settings where a researcher may desire assistance in model building or risk communication. In a pollution context, this has application in determining which neighboring power plants are important determinants of local air pollution levels, and models selecting factors in the built environment that are risk factors for health.
Sara Sauer
Advisor: Sebastien Haneuse
Sara received her Ph.D. in 2021. Dr. Sauer’s dissertation was titled, “Cluster-Based Outcome-Dependent Sampling: Inference and Frameworks for Efficient Sampling Designs”. She is currently a postdoctoral fellow at the Harvard Medical School.
Research: While appointed to the training grant, Sara’s research interests focused on outcome-dependent sampling, particularly in resource-limited settings. During the period being reported, she worked with Dr. Haneuse on statistical methods related to 1) conducting valid inference with data collected via a cluster- stratified sampling scheme, particularly in small sample settings, and 2) exploring how the use of routinely collected group-level information may be used to inform design considerations (i.e. determining which clusters to sample) for the purpose of gains in statistical efficiency.
Michele Zemplenyi
Advisors: Brent Coull and Jeffrey Miller
Michele received her Ph.D. in 2020. Dr. Zemplyeni’s dissertation was titled, “Functional Data Methods for Environmental Epidemiology and Bayesian Experimental Design for Inferring Causal Structure”. She is now an AAAS Science and Technology Policy Fellow at the U.S. Department of Energy’s Federal Energy Management program where she works on federal fleet electrification and energy storage deployment projects to help decarbonize the federal government’s vehicles and facilities. Prior to this position, she was a Project Manager at Urban Ocean Lab, a climate policy think tank for U.S. coastal cities.
Research: While appointed to the training grant, Michele’s research focused on developing statistical methods that reveal how interactions between environmental toxins and the genome affect our health. She worked on a project that aimed to identify epigenetic regions exhibiting critical windows of susceptibility to air pollution using function-on-function regression. Identifying time windows during pregnancy when a fetus is most susceptible to these changes, as well as where in the epigenome these changes occur is a computationally intensive task. She developed a functional data approach that she applied to data the Project Viva cohort. Michele also developed a Bayesian network approach to sequentially design new toxicological experiments designed to identify causal structure within gene networks. Finally, Michele consults on multiple projects helping analyze complex biomedical data, including a project studying the role of prenatal chemical exposures on neurodevelopment in adolescents.
Postdoctoral Alumni (2021-2022)
Aaron Fisher
Advisor: Francesca Dominici
Dr. Fisher is now a Senior Statistical Scientist at Foundation Medicine, Inc., and his research focuses on methods for variable selection in machine learning and artificial intelligence models.
Dr. Fisher’s main project, conducted with Francesca Dominici & Cynthia Rudin, explored how much models can rely on covariates of interest without breaking down. In the course of this project, Dr Fisher developed a theoretical connection between the importance of a binary variable to a model, and the variance of an exposure effect across groups. He extended this work to research on effect heterogeneity, implementing efficient estimation techniques from the influence function literature.
Rachel Nethery
Advisor: Francesca Dominici
Dr. Nethery’s research focuses on causal inference methods for observational data. Her methodological work is motivated by diverse environmental health applications, including the health effects of natural gas infrastructure exposures, the health effects of air pollution exposures, and environmental causes of cancer. She is currently an Assistant Professor of Biostatistics in the Harvard Department of Biostatistics, an Executive Committee member of this training program, and the faculty chair of the Department’s Student Mental Health Working Group.
While appointed to this training program Dr. Nethery worked on causal inference methods to estimate the effects of exposure to natural gas infrastructure on health, to detect spatiotemporal cancer clusters, and to evaluate the health impacts of air pollution regulations. She worked on three major projects. First, she developed novel causal inference methods that allow for improved estimation of the population average causal effect of exposure to natural gas compressor stations on cancer mortality rates. Dr. Nethery compared the methods she developed against existing approaches and found that it out-performed classic methods in the presence of non-overlap, and used this method to perform a novel epidemiological investigation of the causal effects of natural gas compressor station exposure. Second, she developed a causal inference framework for conducting statistical cancer cluster investigations that improves upon the current approach to investigating suspected cancer clusters in several ways. Third, Dr. Nethery worked to develop causal inference methods to evaluate the health impacts of air pollution regulations. The proposed approach utilized her team’s huge, nation-wide dataset of linked pollutant concentrations and Medicare claims data to nonparametrically estimate the number of deaths avoided in the US thanks to simultaneous decreases in multiple air pollutant levels resulting from an implemented regulation.
Corbin Quick
Advisor: Francesca Dominici
Dr Quick’s research focused on developing and applying statistical methods to understand genetic and environmental factors that contribute to risk for complex diseases. Dr. Quick is currently a senior data scientist at Google, Inc.
Dr. Quick developed statistical methods to identify tissues and cell types implicated in the genetic etiology of complex traits and diseases in genome-wide association studies (GWAS), and leveraged this information to help decipher which genetic variants are the causal drivers of GWAS association signals. He applied his new methods to suggest pervasive gene-environment interaction (GxE) effects with respect to the cellular environment in which quantitative traits are expressed. He worked with Dr. Xihong Lin, David Christiani, and others to analyze erythropoietic protoporphyria (EPP) in the UK Biobank, a biobank study of over 500,000 individuals. In another project, he worked with Drs. Lin and Christiani to identify gene- environment interaction (GxE) effects of heavy metal exposure (manganese, lead, and cadmium) on birth outcomes (birth weight and head circumference). The analysis revealed that both PLINK’s and BICS’s GxE test statistics are sensitive to misspecification of exposure effects, and they developed strategies to detect model misspecification and mitigate batch effects in GxE analysis. Finally, he worked to develop an efficient toolkit implemented in C++ for eQTL analysis across multiple tissues and multiple study cohorts, which produced algorithms 10x-100x times faster than existing approaches.
Eric Van Buren
Advisor: Xihong Lin
Dr. Van Buren’s research interests include incorporating single-cell sequencing data into Whole Genome Sequencing data analyses and creating new functional annotations to empower rare variant association discovery. He came to Harvard after completing his doctoral studies funded by an NIEHS-funded T32 at UNC-Chapel Hill.
Dr. Van Buren’s is conducting a project that lies at the intersection of single-cell sequencing technologies and Whole Genome sequencing (WGS) studies. The aim is to incorporate new and existing single-cell sequencing datasets, such as from single-cell RNA-sequencing and single-cell ATAC-sequencing, into existing analysis pipelines for rare variant association studies using large-scale WGS sequencing datasets. Such analyses will allow him to incorporate cell-type-specificity in gene expression and epigenetic signatures which can serve to boost power and increase the scientific relevance of findings. Dr. Van Buren is also interested in applied data analyses in statistical genetics and genomics, such as analyzing single-cell RNA-sequencing data to understand the genetic consequences of exposure to environmental contaminants. He has collaborated with faculty preceptors (Drs. Xihong Lin and Quan Lu) as part of the Harvard Superfund Research Center, analyzing single-cell RNAseq toxicological data with goal of elucidating the adverse impacts of metal exposures on cognitive aging, and the mechanisms by which these effects operate.
