Postdoctoral Scholar - Department of PHS

Job Description Summary

We are seeking a postdoctoral researcher in clinical AI and digital health to join our research group in the Division of Biomedical Informatics & AI, Department of Public Health Sciences, at the Medical University of South Carolina (MUSC) in Charleston. We turn real-world health data into tools that improve care for patients across the lifespan. The postdoc will work closely with Dr. Mamoun Mardini.

Our current work spans three connected areas:
Clinical language models: extracting clinical information from unstructured EHR notes with domain-specific transformer models and LLMs.

AI risk prediction from real-world data: machine learning models built on EHR data for clinical decision support.

Wearables and mobile sensing: passive sensing, ecological momentary assessment and digital biomarkers of physical and cognitive function.
