Jeremiah A. Marsden, PhD
Dr. Marsden is at heart an organic chemist, and secondly a business owner and face of the company. In his lab work, he specialized in heterocycle synthesis, catalyzed cross-couplings, conjugated aromatics, and steroids. Experience includes route optimization, process development, and expertise at transferring a process to production of clinical trial material.
Jeremiah started at Organic Consultants in 2004, and after 8 years as a senior chemist he gained critical skills in synthesis particularly towards pharmaceutical processes. In 2012 he purchased the company from the founder, Lloyd Dolby. As the leader of Cascade Chemistry, he manages the company’s team of chemists, communicates with clients and has grown the company by over 600% since 2012. He can still occasionally be found in the lab, much to the chagrin of the practicing chemists.
Jeremiah earned his PhD from the University of Oregon with Professor Michael Haley where his research involved the synthesis and characterization of phenylacetylene macrocycles and cross-coupling reactions. There he authored nine publications and one book chapter. Dr. Marsden received both a GAAN and IGERT fellowship while at the University of Oregon.
