2026 Summer Intern - Clinical Pharmacology - Real-World Treatment Trajectory Modeling

2026 Summer Intern - Clinical Pharmacology - Real-World Treatment Trajectory Modeling

Department Summary

Clinical Pharmacology is a dynamic function that plays a critical role in supporting drug development teams and in optimizing the dosing regimen for patients. Utilizing our expertise in pharmacokinetics and pharmacodynamics, Clinical Pharmacologists contribute at every stage of development, applying quantitative pharmacology principles across a molecule's life-cycle for both small molecules, biologics, and novel treatment modalities. The Clinical Pharmacology department is instrumental in shaping future treatments and ensuring they are both safe and effective.

This internship position is located in South San Francisco, on-site. 

The Opportunity

• Data Engineering & Cohort Definition: Develop claims-based cohort definitions to extract dispensing patterns, dose levels, and patient characteristics (e.g., body weight, adverse events) from large-scale U.S. insurance claims and/or electronic health record datasets.

• Exploratory Data Analysis: Conduct longitudinal analysis to visualize dose trajectories, quantify medication attrition, and identify switching rates using R or Python.

• Advanced Trajectory Modeling: Implement Latent Class Analysis (LCA) and Group-Based Trajectory Modeling (GBTM) to identify distinct patient subgroups and treatment adherence patterns.

• Predictive Analytics: Explore the feasibility of machine learning approaches (e.g., NCDEs) to predict future treatment trajectories based on baseline patient characteristics.

• Scientific Communication: Synthesize technical findings into clinical insights and deliver a codebase and final report/presentation to the Clinical Pharmacology and Modeling & Simulation teams.

Program Highlights

• Intensive 12-weeks, full-time (40 hours per week) paid internship.

• Program start date is in May/June 2026.

• A stipend, based on location, will be provided to help alleviate costs associated with the internship. 

• Ownership of challenging and impactful business-critical projects.

• Work with some of the most talented people in the biotechnology industry.
