Dr. Hannah L. Prescott

Biography

Dr. Hannah L. Prescott holds a Ph.D. in Materials Chemistry from MIT, where her doctoral research focused on polymer degradation mechanisms under aggressive chemical exposure — work that directly informs the material compatibility data on this site. With 14 years of post-doctoral experience spanning industrial R&D at DuPont, chemical safety consulting for semiconductor fabs, and GHS classification work for ECHA-regulated substances, she brings rigorous analytical methodology to every data point published here.

After observing how often engineers and technicians relied on outdated or anecdotal compatibility charts — sometimes with catastrophic results — Dr. Prescott founded ChemRefHub to provide a single, verifiable, CAS-indexed reference that cross-references manufacturer technical datasheets with ASTM test data. Every compatibility rating on this site traces back to a published source.

Credentials & Expertise

• Ph.D. Materials Chemistry, Massachusetts Institute of Technology (MIT)
• 14 years in chemical safety, materials compatibility, and GHS classification
• Former Senior Research Chemist, DuPont Performance Materials
• Chemical safety consultant for semiconductor and pharmaceutical manufacturing

Role at ChemRefHub

As the founder and lead data editor of ChemRefHub, Dr. Prescott oversees all chemical data sourcing, GHS classification verification, and compatibility rating methodology. Each entry is cross-referenced against at least two independent sources — PubChem for physical properties, manufacturer SDS for compatibility, and ECHA for hazard classification. She reviews user-reported corrections within 5 business days and updates the database quarterly.
