  • Research

    I am a researcher working at the intersection of data science, medicine, and genetics. My research is focused both on methods development for omics data and collaborative applied omics data analysis. My group develops and applies novel machine learning techniques to single cell RNA sequencing, spatial transcriptomics, bulk RNA sequencing, and multi-omic data. Over the past few years, we have focused on the subfield of machine learning called transfer learning that is used to impart knowledge from one dataset to another. By combining multiple disparate datasets, new insights can be derived and the relative strengths of different datasets harnessed. These projects focus on a wide range of diseases, including diabetes, Alzheimer's disease, breast cancer, and multiple myeloma.

    Aside from methods development, we collaborate with groups at Indiana University School of Medicine, Indiana Biosciences Research Institute, and Eli Lilly and Company by providing bioinformatics and data science support. Vast quantities of cutting-edge biomedical data are being generated in the Indianapolis area and frequently require industry-academic partnerships to generate, access, and identify relevant problems to solve. For these reasons, I believe it is imperative to work in a team science setting of diverse contributors, including clinicians, bench scientists, informaticians, data scientists, and industry partners.
