I'm Joshua Pickard, a Eric and Wendy Schmidt Center postdoc at the Broad Institute of Harvard and MIT. I work with the Center for Integrated Solutions to Infectious Disease (CISID) and collaborators across Mass General Brigham and Harvard to develop control theory methods and AI-based digital twins of sepsis and crticial care patients.

Previously, I trained with Indika Rajapakse at the University of Michigan, studying bioinformatics and digital biology for cellular reprogramming. I am passionate about investigating dynamic biomedical systems across a wide range of data and scales 🚀.

• 🤖LLM Powered Digital Biology: AI isn’t just changing what we know but how we work. My Bioinformatics Retrieval Augmented Digital assistant (BRAD) agentic chatbot leverages language models to automate workflows like information retrieval (online), software execution (local), and document search (RAG) to accelerate digital biology research.
• 🔍Biomarker Observability: With recent and rapic advancements in experimental methods, data processing has become a bigger challenge than acquisition. I’m working on observability-based methods to identify meaningful biomarkers in genomic data 🧬.
• 🌐Higher Order Networks: Biological data often needs unconventional analysis techniques. I develop methods and tools like the Hypergraph Analysis Toolbox to study group interactions within genomic networks and beyond.
