Proposed, planned, and executed a $1.8M dollar research effort across three institutions on deep learning for energy storage, resulting in high-impact publications in Nature Machine Intelligence and Patterns.Lead software architect on peer-reviewed software for reinforcement learning over action spaces defined on graphs (NREL/graph-env) (Python, Tensorflow, CI/CD)Lead NREL PI on a 3-year, $1M grant focused on predicting thermotolerance and pH tolerance of enzymatic transformations (NLP, torch)Project lead for a $275K/year subtask under the Co-Optimization of Fuels & Engines initiative. Developed explanatory model for particulate emissions for industry stakeholders using machine learning and Bayesian inference (scikit-learn, pymc).

Golden, Co

Managed a million+ record SQL database with pipelines for ML model training. Published in Scientific Data.Trained a custom graph neural network (tensorflow 2 / keras), and deployed a containerized web application (Docker / FastAPI / Flask, bde.ml.nrel.gov) on AWS with over 8k unique users. Published in Nature Communications.Implemented CI/CD pipelines to automatically update, test, and deploy new models to website services.Pre-trained a BERT-style natural language processing model on 261M unlabeled protein sequences using over 1024 GPUs (torch), fine-tuned resulting model to improve protein annotations on limited data. Recipient of NREL's President's Award (2019)
