Responsibilities

Develop models that predict phase behaviors and physiochemical properties of chemical mixtures across temperature, hydration, and concentration gradients

Build a generative “lab-in-the-loop” modeling pipeline, that incorporates human input of the chemical formulation scientist as well as experimental feedback and proposes the next set of experimental samples to be tested in the wet lab

Build on top of next-generation chemistry ML methods, such as chemical LLMs, reaction prediction, and electronic structure methods like DFT

Own the data flow pipeline, including definition of data standards and processing, data distribution analysis, and visualization to guide the team and inform decision-making processes
