Jonathan McMullen graduated from Lehigh University in 2005 with dual Bachelor of Science degrees in Chemical Engineering and Integrated Business and Engineering. He pursued his graduate studies at MIT under the guidance of Professor Klavs Jensen. His PhD thesis research focused on the design and development of integrated microreactor systems for automated reaction development using direct search and model-based optimization algorithms. In 2010, he joined the Chemical Engineering Research and Development Department of Merck & Co., Inc. and has had roles of increasing responsibility in process development, operations and manufacturing, and technology development within Small Molecule Process Research & Development. Notably, he served as technical lead for developing and commercializing drug substance processes that leverage unique, enabling technologies, such as flow chemistry, immobilized biocatalysis, and photochemistry. He is recognized throughout the industry for subject matter expertise in reaction engineering, kinetic modeling, and scale-up as exemplified in his publication record. He is the recipient of the inaugural AIChE Pharmaceutical Discovery Development and Manufacturing Excellence Award in Technical Innovation, the ACS Green Chemistry Institute Pharmaceutical Roundtable Peter J Dunn Award for Green Chemistry and Engineering Impact in the Pharmaceutical Industry (2021), and is an editorial advisory member for Organic Process Research and Development. He is currently a Senior Principal Scientist, where he is responsible for leading engineering process development on clinical assets and the department’s scientific excellence.
