Jeremiah Marsden

Jeremiah A. Marsden, PhD


Dr. Marsden is at heart an organic chemist. 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 synthetic chemist, he’d gained critical bench and business skills to purchase the company from its founder.  As president, he rebranded it as Cascade Chemistry; expanded its service offerings, growing from 6 employees to almost 50 process, analytical, and quality chemists today; added laboratories and manufacturing suites, including a $14 million GMP API manufacturing facility now under construction; and saw Cascade through its June 2021 acquisition by Aceto – a leading global virtual manufacturer supplying niche, differentiated specialty materials in life sciences and advanced technology end markets.

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.

Micah Bodner

Micah J. Bodner, PhD

Director of Operations

Dr. Bodner earned a Bachelor of Science degree in Biochemistry from the University of Oregon in 2003 where he conducted undergraduate research in chemistry with Professor J. Keana. He earned a PhD in 2010 at the Johns Hopkins University where he worked with Professor C. A. Townsend developing new asymmetric syntheses of carbapenem antibiotics and elucidating the function of enzymes in the thienamycin biosynthetic pathway. This work resulted in four publications and a patent.

He returned to the University of Oregon for a postdoctoral research position in a collaboration between the labs of Professor Michael Haley and Andrew Berglund. His work synthesizing pentamidine derivatives for medicinal and mechanistic studies was funded by a Myotonic Dystrophy Foundation fellowship and a Ruth L. Kirschstein NRSA.

He became a member of Cascade Chemistry in the fall of 2012.

Kevin Johnson

Kevin Johnson

QC Manager

Kevin Johnson graduated from Oregon State University in 2007 with a Bachelor of Science in Microbiology. During his undergraduate work, in 2005, he started working for AVIBiopharma, which later became Sarepta, in their QC department. Initial responsibilities were environmental sampling and monitoring of the cGMP manufacturing suites. This grew into leading API fill/finish activities within the suite and coordinating off-site formulation/fill/finish projects.

In 2008 he began working with Synthetech, which was later acquired by W.R. Grace, in their Quality Control Department. During his 12 years there he built upon his cGMP knowledge in various analytical/QC roles working with amino acid derivatives, organometallic catalysts, and nutraceuticals using a suite of wet-chemistry and chromatographic instrumentation. Increasing responsibilities lead to the facilitation of customer audits, startup of a 21 CFR Part 11 compliant lab, and administration of lab network.
