Overview
As a biostatistician working at the Division of Preventive Medicine at Brigham and Women’s Hospital, my research interests are three-fold:
1) conducting biomarker discovery studies using high throughput metabolomics and other -omics data;
2) analysis of Electronic Health Records data;
3) methodological statistical research on building valid risk prediction models.
My clinical research focuses on the mechanistic pathways of cardiovascular disease development and progression.

The following publications highlight some of my research activities:

    American Hearth Association
    Flexible Framework for Cardiovascular Risk Prediction in a Clinical Setting
    Role Description: The goal of this grant is to evaluate the improvement in prediction using a Flexible Framework. This framework can handle limited information or additional risk factors by combining multiple risk models including both externally derived and validated risk scores as well as models using historic EHR data.
    Role: Principal Investigator

    NIH
    CHD Risk and Metabolomic Profiles of Discordant Lipids
    Role Description: Accurate assessment of cardiovascular risk in the clinical setting is important for appropriate management and counseling of patients. Current US guidelines focus on a single risk score, which does not facilitate inclusion of additional known risk factors or allow for assessment of risk with more limited information, both of which occur in clinical practice. With the growing availability of electronic health record (EHR) data, methods for using all available information to succinctly identify the best course of care are increasingly important. This grant will evaluate the improvement in prediction using a Flexible Framework. This framework can handle limited information or additional risk factors by combining multiple risk models including both externally derived and validated risk scores as well as models using historic EHR data. The results of this project will form the basis for subsequent development of a cloud-based tool for use across software platforms.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
