Contact Information:

Kaetlyn splits her time among several projects at OrACORe, though she spends a majority of her time working on the TeMPO study. She is responsible for patient recruitment in clinic and the performance of musculoskeletal exams and quantitative sensory testing. Additionally, Kaetlyn is investigating the association between adiposity and inflammation in knee osteoarthritis alongside Dr. MacFarlane. Kaetlyn is helping Dr. MacFarlane to initiate her project and will be involved in subject recruitment. She also collects data for the SHielD study and performs qualitative analysis of physician interviews for STriDeS.

Research Assistant
Bowdoin College, 2018
BA in Mathematics

Current Projects: OAPol, SHielD, and STrIDeS
Contact Information:

Peter works on three projects that involve both quantitative and qualitative research. He spends the majority of his time working on OAPol. He focuses on validating and debugging the model as well as performing data updates to ensure that both model inputs and outputs reflect the most recently published data from clinical studies as well as national surveys. Finally, he works to improve the model by adapting the infrastructure already in place to accommodate a greater diversity of covariates such as depression. Additionally, Peter collects data for both the SHielD and STrIDeS studies and works on the STrIDeS data analysis team focusing on cost-effectiveness and creating decision analysis trees using TreeAge software.
