Bio

I am an Assistant Professor of Biostatistics and Health Data Science at Indiana University (IU) School of Medicine. I am also an Adjunct Assistant Professor at the IU Richard M. Fairbanks School of Public Health. I earned my PhD in Biostatistics from Emory University in 2019. I obtained a Bachelor's degree in Mathematics, Statistics and Operations Research from New York University Stern School of Business in 2014.

My methodological research lies in the development of novel statistical methods for analyzing and modeling modern biomedical data of complex and/or mixed modalities. The data modalities I study encompass traditional types that are categorical-, ordinal- and continuous-scaled, as well as those that are highly structured and complex, such as high-dimensional, multi-dimensional, functional (e.g., curve and image) and multi-mode data. The newly developed statistical methods are designed to effectively leverage information from complex biomedical data produced by high-tech medical imaging or wearable technologies, with the overarching clinical goal of facilitating discovery, evaluation and validation of novel non-invasive biomarkers, improving prediction of disease risk and delineating complex pathophysiology of various diseases for their cure and prevention.
