A Summer Tune-Up for Industry Professionals
A popular class on fermentation technology has been attracting mid-career students to MIT for more than 50 years.by Meg Murphy
Kristala Jones Prather is speaking in a packed MIT lecture hall. Many of her students wear reading glasses, some have a little less hair than they used to, and most of them are well dressed and groomed. But all of these engineers, biologists, chemists, microbiologists, and biochemists take furious notes in thick course binders and lean forward to study the equations she jots on the chalkboard.
As Prather delves into Fermentation Technology, a short program offered by MIT Professional Education, she engages and challenges her students. “Do we have a few biochemists? Does this model remind you of anything?” she asks. “It may have been a dark time, but think back to your undergraduate biochemistry class,” she jokes before diving back into her lecture, one of 16 lectures the students will absorb. The course is the oldest in the MIT Professional Education catalog.
Since 1962, this intensive program has attracted industry professionals to campus for five days that promise a review of the fundamentals in the application of biological and engineering principles to problems involving microbial, mammalian, and biological and biochemical systems.
Fermentation Technology gathers a diverse array of professionals to glean the latest insights on terrain they navigate every day at work. It is an opportunity for them to gain knowledge of what might be coming next in biological and biochemical technology, with an emphasis on biological systems with industrial practices. Prather, the Arthur D. Little Professor of Chemical Engineering at MIT, oversees the course with Daniel I. C. Wang, an Institute Professor in the Department of Chemical Engineering.
In addition to Prather and Wang, Fermentation Technology features a mix of guest lecturers that include other MIT faculty and industry professionals, such as Neal Connors from Phoenix BioConsulting in New Jersey, Kara Calhoun from the California biotech company Genentech, and Morris Z. Rosenberg, a biotech consultant in Washington.
As she wraps up her first of two 90-minute lectures of the day, Prather deadpans: “Marinate on that over the break. I’m happy to answer questions when we come back if it’s still not making sense to you.”
As the room empties for lunch, several of the visiting professionals make quick calls into the office or to check on family back home. Bill Morrison, a facilities engineer at BioMarin Pharmaceuticals in San Rafael, California, explains why he’s flown into Boston for hours of difficult lectures. He is moving into a process engineering role at his company and the course material is helpful for the most part. “I’m weak on the theory, but the other part about the mechanism of production is more up my alley,” he says.
Katherine Wyndham from Novavax Inc., a clinical-stage vaccine company headquartered in Gaithersburg, Maryland, says she is a member of the manufacturing, science, and technology group at her company. “This course is really giving me a technical base for what I do,” she says. “I’d say 50 percent is directly applicable to stuff I use every day, and the other 50 percent provides me with new insight into what the process development group does.”
Making additional notes at her lecture seat, Soniya Parulekar of Merck and Company, a global pharmaceutical company, has arrived from Philadelphia for the program. She works in fermentation research and development. “A lot of the things I’m seeing discussed in this course are giving me a better sense of what I’m working on — a deeper knowledge,” she says.
Soon enough Prather is back from lunch. She begins to animatedly discuss modeling and bioprocess monitoring as industry professionals from across the country settle into their chairs to absorb as much information as they can.
There are 2.5 days left of the course. Or to be exact, seven more lectures, including: perfusion reactors, medium design and high cell-density cultivation, power requirement in bioreactors, oxygen transfer and shear in bioreactors, design of experiments, analytics in biomanufacturing, and bioprocess simulation and economics. Attention in the room is still running high.
For Prather, teaching a room full of professionals offers interesting opportunities as a teacher. “I teach the same material in my biochemical engineering class for undergraduates,” she says. “The short-course students bring a much richer perspective based on their own professional experiences. Sometimes,” she adds, “they teach me things that I can then offer to our own students.”
