Boot Camp Overview

Summer 2024 dates: In-person training July 18-19, 2024; 10am EDT - ~5pm EDT

There are many challenges to capturing the complexity of exposures in an individual across the lifetime and their potential health effects. Traditionally, environmental health studies have focused on assessing risks related to a single exposure at a time, yet in reality we are constantly exposed to multiple exposures at the same time. To advance environmental health research and positively impact human health through recommendations and policy, we need to incorporate omics data that capture all chemical species detectable in human plasma over the life course. The exposome offers this framework and can be viewed as the environmental complement of the genome.

This two-day intensive boot camp integrates the principle concepts of exposomics and the untargeted approaches of measuring endogenous and exogenous chemical exposures on an omic scale as we step through the tools and techniques currently available to analyze the exposome. Led by a team of expert scientists in the rapidly growing field of exposomics, the boot camp will integrate seminar lectures with hands-on computer lab sessions to put concepts into practice. Emphasis will be given to leveraging existing resources from ongoing studies and initiating new investigations. The afternoon lab sessions will provide an opportunity to work hands-on with real data. Participants will learn and practice data handling, cleaning, and basic analysis of exposomics data.

By the end of the workshop, participants will be familiar with the following topics:

  • Principles of exposomics
  • Concept ideation and study design
  • Laboratory methods and instrumentation platforms for analysis
  • Data extraction and cleaning with emphasis on peaks and feature tables
  • Pathway data analysis and identification databases
  • Data visualization and network interpretation
  • Study design advantages and pitfalls
  • Emerging exposomic topics and laboratory platforms

Audience and Requirements

Investigators at all career stages are welcome to attend, and we particularly encourage trainees and early-stage investigators to participate.

This training is designed to accommodate investigators with varying experience levels in R. Knowing R basics is beneficial to maximize training from the boot camp, but is not necessary for you to strongly engage with training material. Data labs will be offered during the training and are meant to accommodate both beginner and advanced data manipulation, with all material and additional resources available after the training. There are three requirements to attend this training:

  1. Each participant must have an introductory background in statistics.
  2. Each participant is required to have a personal laptop. If you would like to participate in the asynchronous, hands-on data labs offered by the Boot Camp, you will need to have R downloaded and installed as all lab sessions will be done on your personal laptop. R is available for free download and installation on Mac, PC, and Linux devices.  
  3. The Boot Camp will provide lab tutorials with data sets in R, therefore we recommend participants have a basic understanding of this platform prior to attending the Boot Camp to get the most out of lab sessions. R knowledge is not required if you do not plan to participate in lab sessions. If you have not used this platform before, step through the tutorials outlined below so you have the basic skills needed for Boot Camp success.

R Tutorials

As noted in the prerequisites above, knowing basic R platform and commands is recommended, but not required, to get the most out of the lab sessions. If you are new to R or need a refresher, review the below tutorials to be well-prepared for the labs:

If you have any specific questions about R and R studio in the context of the Exposome Boot Camp, please email us.


Summer 2024 instructing team is being finalized, but will be comparable to the 2023 lineup below.

Training Director: Gary Miller, PhD, Professor of Environmental Health Sciences and Vice Dean of Research Strategy and Innovation, Mailman School of Public Health, Columbia University. Dr. Miller was the founding Director of the HERCULES Center at Emory University, the first exposome-based research center in the U.S. and authored the first book on the topic, The Exposome: A Primer published by Elsevier. His laboratory at Columbia focuses on environmental drivers of neurodegeneration, using several experimental models from cultured neurons and C. elegans to mice and human studies.

Doug Walker, PhD, is an Associate Professor in the Gangarosa Department of Environmental Health at Emory University and adjunct Assistant Professor at Utrecht University.  At Emory University, Dr. Walker’s research focuses on continued development and application of advanced analytical strategies for measuring the occurrence, distribution and magnitude of previously unidentified environmental exposures and assisting in delineating the mechanisms underlying environment-related diseases in humans. The approaches he developed show it is possible to measure over 100,000 chemical signals that include exposure biomarkers, nutrients, dietary chemicals and associated biological response in a high-throughput and cost-effective manner, establishing a foundation for operationalizing the exposome framework for precision medicine. Ongoing research projects are now focused on using high-throughput exposome methods to establish disease-exposome atlases, and development of methods for measuring biomarkers of complex exposures of emerging concern, including microplastics, e-waste and polyfluorinated chemicals. 


Xin Hu, PhD, Assistant Professor of Medicine, Department of Medicine, Division of Pulmonary, Allergy Critical Care and Sleep Medicine, Emory University. Dr. Hu was trained in metabolomics and integrative omics with over 15 years of research experience in environmental health and molecular pulmonary toxicology. She is experienced with analyzing and integrating high-dimensional datasets in experimental and populational research. Her research employs a multidisciplinary approach, utilizing metabolomics, exposomics, bulk and single-cell transcriptomics, as well as epigenomics, to unravel the molecular dysregulation underlying environmental factors' impact on lung pathology.
