2024 Faculty lightning talks
Each year, members of our faculty participate in lightning talks as an opportunity to share their research interests, current projects, and potential collaboration opportunities with students in our graduate program. These presentations help students explore different avenues of investigation and brainstorm potential projects that can contribute to their theses or dissertations.
Here are the faculty members who participated in the 2024 talks and their current research focuses:
- Randomized controlled trials (RCT)
- Observational study data
- Current project: Greenlight Plus study
- Control: designed to promote healthy growth through a low-health literacy toolkit to enhance pediatric primary care
- Intervention: automated text messaging that reinforces goals around health behaviors
- Primary analysis: longitudinal mixed model that compares average growth trajectories
- Contact jonny.schild@vumc.org
- Rank-based analysis methods and applications
- Statistical methods research
- Computing skills
- Applications to biomedical studies, particularly HIV/AIDS and other global health diseases
- Looking for a PhD student to help with research for the summer/fall
- Contact bryan.shepherd@vumc.org
- Distance-based model for high-dimenstional data
- Robust semiparametric model
