2016-2019NIH 1R21 AI 121784-01 (Co-I), The representative microbiome: social determinants and tools for population research.
 The purpose of this study is to describe sociodemographic variation in the oral microbiome in a national population-based sample. Links between the human microbiome and health are just beginning to emerge and could provide novel prevention and intervention strategies for health disparities.

2015-2018NIH 1R03 CA 191447 – 01A1 (PI), Validation and clinical relevance of ovarian cancer subtypes.
 This project employs meta-analysis to resolve uncertainty around the robustness and relationship to patient outcome of proposed molecular subtypes of ovarian cancer. It establishes whether genetic heterogeneity within tumors is likely to be an obstacle to subtype-specific therapies. It provides open-source implementations of all proposed subtypes to facilitate their usage by other translational researchers. These objectives will facilitate adoption of the most clinically relevant molecular subtypes to inform precision treatment of ovarian cancer.

2014-2019NIH U24CA180996 (Co-I), Cancer genomics: integrative and scalable solutions in R/Bioconductor.
 Researchers collect diverse types of complex genetic information about factors that contribute to cancer. This proposal helps researchers manage and analyze this information using advanced computational and statistical approaches.
2013-2018NIH 5R01MH101028-03 (Co-I), HIV care coordination: comparative effectiveness, outcome determinants, and costs.
 This study aims to assess the effectiveness of the NYC Ryan White comprehensive HIV Care Coordination Program (CCP) relative to that of usual care outside the CCP for persons living with HIV and residing in NYC, to determine what individual and program-level factors are associated with optimal care outcomes for CCP participants and to determine the cost-effectiveness of the CCP relative to usual care outside the CCP.
