A Brief Overview

The mission of the Campbell Laboratory at the Children’s Hospital of Philadelphia is to ensure that every child with a rare genetic disease is diagnosed as quickly and accurately as possible. We believe that a promising approach is to use large language models (LLMs) to better understand our patients’ health and intervene in the electronic health record to facilitate diagnosis. We hope these approaches can help address inequities in the way genetic care is provided to patients from historically marginalized backgrounds. Our lab performs training of LLMs using both on-premises GPUs as well as by taking advantage of cloud-based resources. We are seeking a data scientist to assist with the collection, standardization, and analysis of data from the electronic health record and to assist in implementation of LLM training in the cloud. The data scientist will have the opportunity to work with physicians, nurses, and laboratory professionals to improve the care of children.

The data scientist will work closely in-person with the laboratory director, Dr. Ian Campbell, and other data scientists and trainees to advance the mission of the laboratory. The laboratory’s LLMs are implemented in Python (PyTorch, JAX) using data extracted from electronic health record (Epic) relational databases. Thus, familiarity with Python and basic SQL are required. The data scientist will contribute to reproducible research by committing high quality and well documented code to the enterprise and public GitHub.

The Campbell Lab is committed to diversity and strives to create an equitable work environment for everyone. Individuals from historically marginalized backgrounds are strongly encouraged to apply.
