Research plays a small, but key part in my current role at Eli Lilly. Our research is primarily in educating and communicating statistical results to non-technical audiences. We are developing methods and metrics that are interpretable and drive critical business decisions, while also representing statistical variability and uncertainty. In my free time, I lend out my statistical expertise for a range of applications.
My Ph.D. thesis was on the development and application of functional data methods, including goodness-of-fit tests for covariance models and non-Gaussian data. I was also part of the Bill and Melinda Gates Foundation's Healthy Birth and Growth Knowledge Initiative (HBGDki), developing nonparametric methods for modeling and prediction of fetal and child growth. My applied work with the IPAC-RS Population Bioequivalence (PBE) working group explored the performance of the PBE and other equivalence criteria for evaluating in vitro bioequivalence in aerosol medications.
In a previous academic life, I was part of the Continential Environments Research Group and Smith Lab conducting geology and paleobotany research on the use of phytoliths and isotopes for environmental reconstruction. My undergraduate honors thesis and Fulbright scholarship work was on the nutritional ecology of golden snub-nosed monkeys in China. I still collaborate in the ecological space on statistical modeling.

Fun fact: Ben Blanchard and I were high school classmates and college roommates. We joked for years about co-authoring a paper together, and finally made it happen!Chen ST, Luo X, Hou R, et al.
