Kristala Jones Prather is an American biochemical engineer and professor known for pioneering work in metabolic engineering, synthetic biology, and bioprocess development. Her career spans industrial research in pharmaceutical industry settings and academic leadership at a major research university, where she directs a laboratory that integrates microbial fermentation, enzyme engineering, and metabolic pathway design to produce fuels, chemicals, and pharmaceuticals. She has been recognized by multiple professional societies and funding agencies for contributions to translational biotechnology and engineering education.
Prather was born in Louisville, Kentucky and raised in a family engaged with science and engineering professions in the United States. She completed a Bachelor of Science degree in chemical engineering at the University of Delaware, followed by graduate study at the Georgia Institute of Technology, where she earned a Master of Science in chemical engineering under advisors working at the intersection of bioprocess engineering and microbial physiology. She obtained her Ph.D. in chemical engineering from the Massachusetts Institute of Technology studying metabolic pathway design and enzyme function with faculty active in synthetic biology and metabolic engineering. During her training she worked alongside researchers connected to institutions such as Harvard University, Stanford University, UC Berkeley, Caltech, and national laboratories including Lawrence Berkeley National Laboratory.
Prather began her professional career with a position in the pharmaceutical industry at a multinational company where she contributed to early process development and scale-up for small-molecule and biologic products, collaborating with groups from Merck & Co., Pfizer, Eli Lilly and Company, Novartis, and Roche. She transitioned to academia as faculty in the Department of Chemical Engineering at the Massachusetts Institute of Technology, where she holds a named professorship and leads the Prather Lab. Her laboratory maintains collaborations with investigators at Broad Institute, Whitehead Institute, Wyss Institute, MIT Lincoln Laboratory, and industrial partners including Genentech, Biogen, Amgen, and startups emerging from MIT Technology Licensing Office. She has served on advisory boards for companies incubated at Kendall Square and engaged with consortia such as the National Academy of Engineering and the American Institute of Chemical Engineers.
Prather’s research portfolio focuses on engineered Escherichia coli, Saccharomyces cerevisiae, and non-model microbes for production of value-added chemicals, therapeutics, and biofuels. She developed strategies in dynamic pathway regulation, modular biosynthetic pathway construction, and enzyme optimization to improve titers, rates, and yields—approaches related to work by investigators at Lawrence Livermore National Laboratory, Sandia National Laboratories, and DOE Bioenergy Research Centers. Notable projects include engineered pathways for terpenoid and polyketide biosynthesis, microbial production of small-molecule precursors for pharmaceuticals, and cell-free enzyme systems aligning with efforts at J. Craig Venter Institute and Synthetic Genomics. Her lab has advanced techniques in real-time metabolic control, CRISPR-based regulation applicable to methods used at Broad Institute, and metabolic flux analysis comparable to studies from ETH Zurich and Max Planck Institute for Terrestrial Microbiology.
Prather has received recognition from national and international bodies, including early-career awards from the National Science Foundation, a CAREER Award in support of interdisciplinary research at the interface of engineering and biology, and invited lectureships such as the NAE Gilbreth Lecture. She has been elected to leadership roles in the American Institute of Chemical Engineers and honored by societies including the American Chemical Society and the Biochemical Engineering Society. Her laboratory’s translational impact has been noted by seed funding from agencies like the Defense Advanced Research Projects Agency and partnerships supported by National Institutes of Health grants.
Representative publications by Prather and colleagues appear in journals such as Nature Biotechnology, Science, Proceedings of the National Academy of Sciences, ACS Synthetic Biology, Metabolic Engineering, and Biotechnology and Bioengineering. Her work includes articles on pathway balancing, dynamic regulation, and heterologous expression of complex biosynthetic clusters. She is an inventor on patents covering engineered microbial strains, pathway architectures, and methods for controlling metabolic flux, with filings involving technology transfer offices and corporate partners similar to those at MIT Technology Licensing Office and Cambridge Innovation Center.
Prather participates in peer review for federal agencies including National Science Foundation, National Institutes of Health, and Department of Energy programs, and serves on editorial boards for journals in biotechnology and chemical engineering. She has mentored graduate students and postdoctoral researchers who have joined academia, industry, and government labs such as UC San Diego, University of Illinois Urbana–Champaign, University of Texas at Austin, and national laboratories. Her outreach includes engagement with K–12 STEM initiatives, public lectures in venues like the Museum of Science (Boston), and involvement with diversity and inclusion programs affiliated with Society of Women Engineers and National Society of Black Engineers.
