Postdoctoral Scholar - Research Associate

The newly establishedDogra Lab (https://mann.usc.edu/faculty/dogra/)at USC invites applications for two Postdoctoral Scholar - Research Associates at the intersection of artificial intelligence (AI), mechanistic modeling, and quantitative systems pharmacology (QSP). Funded by an NIH R01, our group develops predictive frameworks that integrate advanced AI/ML methods with multiscale mechanistic models of disease biology and drug action to inform drug development and clinical pharmacology in cancer, vaccines, infectious diseases, nanomedicine, and drug delivery systems.

Led by Dr. Prashant Dogra, a computational medicine scientist with expertise in mechanistic modeling and quantitative pharmacology, the lab is building innovative tools to accelerate clinical translation and support drug development.

Joining the Dogra Lab offers a unique opportunity to help build a new lab from the ground up, shape research directions, and grow into leadership roles in academia, pharma/biotech, or entrepreneurship.

Why join us?

• Innovation:Contribute to cutting-edge research at the interface ofAI/ML and mechanistic modeling. Depending on your track, you may focus on:

• Track A (AI/ML):Developingphysics-informed neural networks (PINNs)for integrating mechanistic constraints into ML frameworks, and creatingLLM-based agentsto assist with mechanistic model construction and knowledge curation.
• Track B (Mechanistic modeling):Building and analyzingmultiscale modelsthat capture biological plausibility and connect with AI/ML frameworks to address complex therapeutic challenges.

• Impact:Contribute to research that aligns withNIH and FDA prioritiesin advancing AI and New Approach Methodologies (NAMs) to reduce reliance on animal testing and accelerate drug development, while also opening translational and deep-tech commercialization opportunities.
• Training:Access specialized courses, workshops, and USC's strong ecosystem inmodel-informed drug development (MIDD), PBPK modeling, clinical pharmacology, and pharmacometrics.
• Mentorship:Receivepersonalized guidancefrom a tenure-track PI and NIH R01 awardee (2024), with cross-disciplinary training and a proven record of helping trainees achievehigh-impact publications and successful career transitions. Support includes structured feedback inpublishing, grant writing, and professional networking.
• Independence and funding:Build your research independence through opportunities to apply forfellowships and K awards, present atnational and international conferences, and develop skills aligned withtenure-track opportunities. Postdoctoral scholars targeting careers inpharma or consultingwill benefit from tailorednetworking and professional guidance.
