• Ethylene Oxide Taskforce:o EtO hemoglobin adducts: Preformed statistics and EDA using NHANES data on biomarkers of tobacco smoking (survey data, multi-faceted plots, linear modeling, LASSO variable selection) and presented findings to Taskforce leads. Research into other smoking biomarkers to include into analysis, including effects of marijuana smoking. Additional analysis on NHANES data using different parameters to include more smoking groups and new biomarker level. Help in creating summaries of NHANES data for use in PBTK modeling. “Interpreting Biomonitoring Data: A case study for ethylene, ethylene oxide, and hemoglobin adduct” (Ruiz et al.)o EtO Air Monitoring, GA: Analysis using change point analysis showing timepoints where there is change in EtO concentrations. Data mining of canisters of EtO samples using pdf files from EPD website. Statistics and EDA on three different sites (ANCOVA, analysis of variance, Kruskal-Wallis, Dunn/Dunnett test, Peto-Peto test) Use of GAMs and Bayesian modeling to solve for bias coming from the observations in the data.• PFAS EPA IAA:o Calculating initial sample size using power curves based on NHANES data and presented findings.o Initial statistics and EDA using previous EI datasets (summaries, boxplots, relationships between different sample media, biplots).o Future travel to sites for in-person soil sampling experience.• NCEH ATSDR EDAV Evaluation Tiger Team:o Testing and evaluating of features and functionalities of EDAV program as a team consisting of members from different backgrounds.o Feedbacks using evaluation document.• Penobscot Fish project:o Tabulate qualifiers, summarize detection limits, EDA for PFAS (Wilcoxon, Kruskal-Wallis, boxplots, PCA/biplots, GAMs, multidimensional analysis, anosim).o Cross-agency collaboration using github for managing work with EPA.
