• Dietary Fructose Alters the Composition, Localization, and Metabolism of Gut Microbiota in Association With Worsening Colitis

  Cellular and Molecular Gastroenterology and Hepatology · 2020 · 100 citations

  BACKGROUND & AIMS: The incidence of inflammatory bowel diseases has increased over the last half century, suggesting a role for dietary factors. Fructose consumption has increased in recent years. Recently, a high fructose diet (HFrD) was shown to enhance dextran sodium sulfate (DSS)-induced colitis in mice. The primary objectives of the current study were to elucidate the mechanism(s) underlying the pro-colitic effects of dietary fructose and to determine whether this effect occurs in both micr…

• Career choices of underrepresented and female postdocs in the biomedical sciences

  eLife · 2020 · 89 citations

  The lack of diversity among faculty at universities and medical schools in the United States is a matter of growing concern. However, the factors that influence the career choices of underrepresented minority and female postdoctoral researchers have received relatively little attention. Here we report the results of a survey of 1284 postdocs working in the biomedical sciences in the US. Our findings highlight possible reasons why some underrepresented minority and female postdocs choose not to p…

• Statistical Inference for Association Studies in the Presence of Binary Outcome Misclassification

  Statistics in Medicine · 2025-02-06 · 2 citations

  articleOpen accessSenior author

  In biomedical and public health association studies, binary outcome variables may be subject to misclassification, resulting in substantial bias in effect estimates. The feasibility of addressing binary outcome misclassification in regression models is often hindered by model identifiability issues. In this paper, we characterize the identifiability problems in this class of models as a specific case of "label-switching" and leverage a pattern in the resulting parameter estimates to solve the pe…

• Estimand-based inference in the presence of long-term survivors

  Statistical Methods in Medical Research · 2025-03-31 · 1 citations

  articleSenior author

  In this article, we develop nonparametric inference methods for comparing survival data across two samples, beneficial for clinical trials of novel cancer therapies where long-term survival is critical. These therapies, including immunotherapies and other advanced treatments, aim to establish durable effects. They often exhibit distinct survival patterns such as crossing or delayed separation and potentially leveling-off at the tails of survival curves, violating the proportional hazards assumpt…
