Machine Learning Scientist / Sr Scientist - Uncertainty Quantification & Influencer Analysis

JOB DESCRIPTION

At Lilly, we unite caring with discovery to make life better for people around the world. We are a global healthcare leader headquartered in Indianapolis, Indiana. Our employees around the world work to discover and bring life-changing medicines to those who need them, improve the understanding and management of disease, and give back to our communities through philanthropy and volunteerism. We give our best effort to our work, and we put people first. We’re looking for people who are determined to make life better for people around the world.

Purpose

Lilly TuneLab is an AI-powered drug discovery platform that provides biotech companies with access to machine learning models trained on Lilly's extensive proprietary pharmaceutical research data. Through federated learning, the platform enables Lilly to build models on broad, diverse datasets from across the biotech ecosystem while preserving partner data privacy and competitive advantages. This collaborative approach accelerates drug discovery by creating continuously improving AI models that benefit both Lilly and our biotech partners.

The Machine Learning Scientist / Sr Scientist - Uncertainty Quantification & Influencer Analysis plays a dual role within the TuneLab platform, responsible for both quantifying prediction uncertainty in federated models and attributing value from partner contributions to model predictions. This position requires expertise in statistical methods, uncertainty quantification, and data valuation, combined with knowledge of drug discovery to ensure reliable predictions and fair partnership dynamics. The role is critical for building trust in model predictions and maintaining equitable, sustainable collaborations within the TuneLab ecosystem.

Key Responsibilities

• Conformal Prediction Implementation : Design and deploy conformal prediction algorithms adapted for federated learning, providing rigorous prediction intervals and confidence sets that maintain validity despite data heterogeneity across partners and distribution shifts.
• Uncertainty-Driven Valuation : Develop methods that use uncertainty quantification to assess data quality and value, identifying contributions that most effectively reduce model uncertainty in critical regions of chemical / biological space.
• Contribution Attribution Systems : Implement fair attribution mechanisms (Shapley values, influence functions, leave-one-out analysis) that quantify each partner's contribution to model performance while maintaining privacy and computational efficiency in federated settings.
• Calibration Under Heterogeneity : Create robust calibration techniques that account for varying data quality, experimental protocols, and noise levels across partners, ensuring reliable uncertainty estimates for all participants.
• Value-Weighted Aggregation : Design federated aggregation schemes that weight partner contributions based on data quality, relevance, and uncertainty reduction, optimizing global model performance while maintaining fairness.
• Active Learning Strategies : Develop uncertainty-guided and value-aware active learning approaches that identify high-value experiments across the federation, maximizing information gain while respecting partner resources and priorities.
• Risk-Aware Decision Support : Translate uncertainty estimates into risk-adjusted recommendations for drug discovery decisions, helping partners understand when to trust predictions versus conduct experiments.
• Incentive Mechanism Design : Collaborate with business development to create incentive structures based on quantified contributions and uncertainty reduction, encouraging continued high-quality data sharing while preventing gaming.
• Quality Metrics Development : Establish comprehensive quality metrics that combine uncertainty quantification with data characteristics (diversity, annotation quality, experimental consistency) to assess partner contributions holistically.
• Strategic Data Recommendations : Use uncertainty and value analysis to identify optimal characteristics for future partnerships, predicting which data types, assays, or therapeutic areas would most improve federated models.
