Job Overview

The Joshi Lab (PI: Dr Priyanka Joshi) is seeking a highly motivated Masters-level Research Associate to join our interdisciplinary team at the intersection of artificial intelligence and protein engineering. This unique position combines cutting-edge computational modeling with hands-on laboratory experimentation to design and validate novel proteins using state-of-the-art protein language models.

Key Responsibilities

Computational Modeling & AI Development

• Train and fine-tune ESM (Evolutionary Scale Modeling) protein language models on curated datasets to generate novel protein sequences
• Develop and optimize machine learning pipelines for protein design, including data preprocessing, model training, and validation protocols
• Analyze protein structure-function relationships using computational tools and databases
• Implement and maintain bioinformatics workflows for sequence analysis and protein characterization
• Collaborate on algorithm development to improve protein generation accuracy and diversity

Laboratory Experimentation

• Express, purify, and characterize computationally designed proteins using standard molecular biology techniques
• Perform protein purification protocols including chromatography, electrophoresis, and spectroscopic analysis
• Conduct functional assays to validate AI-generated protein designs and assess their biochemical properties
• Maintain detailed laboratory records and ensure compliance with safety protocols
• Troubleshoot experimental procedures and optimize protocols for improved protein yield and purity

Research Integration & Analysis

• Bridge computational predictions with experimental validation through iterative design-build-test cycles
• Analyze experimental results to inform and improve machine learning model performance
• Prepare comprehensive reports documenting both computational and experimental findings
• Present research results at team meetings and contribute to scientific publications
• Collaborate with cross-functional teams including computational biologists, biochemists, and software engineers

Work Interactions

The Research Associate will work directly with the PI and collaborate with the lab members and any external collaborators.
