• Developed one of the first fully integrated retrobiosynthesis software tools to autonomously suggest the biosynthesis and semi-synthesis of small-molecules using both multifunctional and monofunctional enzymes as well.
• Deployed previously trained XGBoost and message-passing GNN models to accelerate the design of feasible biosynthetic pathways.
• Built and used a molecular docking pipeline with tools, such as DiffDock, GNINA, SMINA, posebusters, and py3Dmol to aid synthetic biologists in the computational protein design of potentially promiscuous enzymes.
• Designed a microservice architecture to deploy all resulting software on the web for easy use by synthetic biologists. Docker was used to containerize a frontend GUI (streamlit), a backend (Django + retrobiosynthesis.

• Synthetically generated over 11 million infeasible enzymatic reactions to circumvent the lack of negative data in the literature by strategically considering alternate reaction sites on substrates within the.
• Trained XGBoost binary classification models on resulting datasets to predict the feasibility of novel reactions. Models were trained using GPUs on high-performance computing clusters and in a distributed fashion via.
• Built an end-to-end data processing pipeline with RDKit to sanitize raw reaction data and create digital fingerprints of processed reactions that were ultimately assembled into feature vectors for machine learning.
• Deployed this data pipeline to perform stratified train/ test/ validation splits while removing any duplicated feature vectors to minimize leakage between sets. Model hyperparameters were optimized on the validation.
• Performed synthetic over-sampling of the minority class via the synthetic minority over-sampling (SMOTE) technique available in Scikit-learn so as to mitigate any class imbalance effects.
• Benchmarked final XGBoost models trained on both fingerprint-based and description-based reaction feature vectors against existing models in the literature and demonstrated that our models perform better across all key.

• Improved existing experimental apparatus and procedures to accurately perform adsorption measurements of gaseous hydrocarbons (methane, ethane, 2,2-dimethylbutane) in various zeolite frameworks and molecular sieves at.
• Developed a robust algorithm in Python to invert experimentally obtained adsorption data and elucidate likely underlying distributions of crystallite radii present in various zeolite samples by statistically.
• Executed such algorithms by utilizing Lawrence Berkeley National Laboratory's high performance computing resources
• Collaborated with research scientists from Chevron to perform adsorption measurements on proprietary zeolite catalysts developed at Chevron and communicated research findings back to Chevron scientists
• Presented research findings at undergraduate research fairs and group meetings. Wrote an honors' on the techniques and algorithms researchers can employ to accurately conduct adsorption measurements in porous materials
