Paul Larsen joined Dow Chemical in 2007 as a crystallization scientist within Dow's Core R&D organization after receiving a Ph.D. in chemical engineering from the University of Wisconsin-Madison. Paul supported global projects across Dow's agricultural and specialties businesses, receiving six "Dow Tech Center" awards for projects that each generated 2-5MM USD/yr EBIT. In 2016, Paul transferred to Dow Agrosciences/CortevaTM Agriscience, continuing as a crystallization expert while broadening his impact to formulated products.
Paul’s crystallization expertise has addressed critical needs at Corteva for active ingredient manufacturing and formulation design, influencing the development and manufacturing of over 30 active ingredients and dozens of formulated products. His fundamental, holistic approach to crystallization has enhanced Corteva’s crystallization process development, leading to significant value generation. He championed solvent screening protocols along with interactive visualizations integrating solubility data with solvent EH&S information, thus facilitating holistic solvent selection for safer, more environmentally friendly products and improved sustainability of Corteva’s processes and products. In addition, Paul has developed the polymorphism strategy for Corteva’s pipeline active ingredients.
Currently, Paul is an Associate Laureate and crystallization expert working on the development and scale-up of new active ingredients. He has championed education and external engagement, initiating an ongoing crystallization research program with Purdue (Prof. Zoltan Nagy) and developing an internal crystallization design course. Paul leads the Corteva Particle Technology Community of Practice and serves externally on the Association for Crystallization Technology steering committee. He enjoys mentoring young scientists and has supervised nine interns over his career.
