Scientific Team



MARY RICHARDSON, PhD, DABT - Chief Scientific Officer, Executive Vice President

As Chief Scientific Officer at iuvo BioScience, Mary, one of the company's co-founders, heads up the Research and Development team. Most recently Mary served as Executive Director of Preclinical Development at Bausch & Lomb, continuing in that role when Valeant Pharmaceuticals purchased the company. Previously, she was Director of Nonclinical Safety.

Her extensive background includes in-depth research and development experience covering the full range of the preclinical product life cycle including discovery, product development, and post-market support in areas including life cycle management, geo-expansion and manufacturing. Her knowledge of global regulations and standards for registration of pharmaceutical and medical device products is exhaustive.

Her technical leadership and expertise in drug development of small molecules, peptides, and medical devices has resulted in regulatory approval and success of numerous NDAs, INDs, IMPDs, and 510(k) submissions. She’s an in-demand speaker with many published articles in scientific journals.

Mary earned her PhD from the University of Rochester School of Medicine and Dentistry and is a highly experienced board-certified toxicologist (Diplomate of American Board of Toxicology – DABT) with broad-based technical skills in pharmaceuticals, OTC, medical devices, drug metabolism, toxicology, pharmacokinetics, and pharmacology.

CHRISTOPHER HOUSTON, PhD - Director of Analytical Chemistry

Dr. Christopher Houston is the Director of Analytical Chemistry at iuvo BioScience. Prior to joining iuvo, Chris was a Senior Principal Scientist at Bausch & Lomb for ten years. In this time, he led the centralized mass spectrometry facility, co-founded and led a collaborative multidisciplinary spectroscopy group focused on scientific problem solving and elucidation of unknown chemical entities, and established Bausch + Lomb’s successful program for Extractables & Leachables (E&L) that extended from new product development to management of post-market packaging changes.

Chris is an world-recognized subject matter expert in E&L, particularly in ophthalmology; a frequent speaker at E&L meetings; and a member of the PQRI Working Group on E&L in Parenteral and Ophthalmic Drug Products (PODP).

Chris began his career at Pharmacia & Upjohn (which later became Pharmacia Corp, then Pfizer) as an analytical project lead responsible for chromatographic method development and validation. In this role, he also created a strategy for E&L in ophthalmic drug products and founded an analytical laboratory focused on solving problems and providing rapid directional studies during pharmaceutical development.

Chris has a B.S. degree in Chemistry from the University of Michigan – Flint where he was involved in a drug-design research program involving chemical synthesis and characterization of the products by cyclic voltammetry and mass spectrometry. He holds a PhD in Analytical Chemistry with a minor in Biochemistry from Indiana University – Bloomington where he utilized matrix-assisted laser desorption / ionization time-of-flight mass spectrometry (MALDI-TOFMS) to study chemical modifications of proteins in the solving of biochemical problems.

Chris is a 1600+ hour instrument-rated private pilot and lives in the Rochester area with his wife, a music teacher, and daughter.
