ABOUT

A Scientist Who Communicates Complex Chemistry Clearly

 

Dr. Abato brings deep, hands-on pharmaceutical experience to the courtroom. His career spans the full drug development lifecycle — from medicinal chemistry and lead optimization through formulation, stability studies, pharmacokinetics, and IND submission.

He has contributed to the discovery of five preclinical candidates for Multiple Sclerosis, Arthritis, and Spinal Muscular Atrophy, and co-authored a pre-IND proposal for SMA that received a favorable review from the FDA.

As an adjunct professor at Roger Williams University, Dr. Abato is practiced at explaining complex scientific concepts to both science and non-science audiences — a critical skill when educating judges and juries.
