At Mironova Labs, I lead research, development, scale-up, and process innovation for cosmetic ingredients and specialty chemicals. I expanded the commercial portfolio from 3 to 30+ molecules and direct a five-person R&D team, a roughly $1M annual budget, and three concurrent development programs.

As Senior Scientist, Process Chemistry at Mironova Labs, I developed and scaled a synthetic L-(+)-ergothioneine route to 5 kg non-GMP batches at 99+% purity, reducing production cost from approximately $15,000/kg to $2,000/kg. I also redesigned the cloprostenol process and developed an automated flash chromatography method that recovered about 30% more material.

Through MG Scientific Solutions, I advise scientific and technology companies on R&D, product development, scientific workflows, and digital tools. I collaborate with the development team behind Helix, translating laboratory and manufacturing requirements into software functionality and workflows, and I develop and evaluate AI-enabled scientific workflows.

My research has included organic electrosynthesis at KTH Royal Institute of Technology and catalytic and materials research at the Institute for Basic Science. I’ve authored 33 peer-reviewed publications, including work in JACS and Angewandte Chemie.
