5 Unique Molecular Biology Jobs You May Not Have Heard Of

When imagining molecular biology jobs, do you find yourself stuck in a single lane? The cultural idea of a “scientist” is often limited to the traditional academic researcher or professor. But there’s a whole world of alternative molecular biology careers out there for those who are passionate about the field. 

The “Speaking of Mol Bio” podcast aims to bring those possibilities to light, with scientist guests of all backgrounds coming together to share their current non-traditional molecular biology jobs and the career journeys that led them there.

In this blog, we introduce 5 molecular biology experts pursuing their diverse passions in government, industry, and beyond. From beer brewing to science writing, each episode’s guest is making their mark on the field.

Molecular biology jobs in the spotlight: 5 experts share their experiences

1. Beer brewing and fermentation science

🔗

Kelly Tretter, Senior Quality Integration Manager, New Belgium Brewing

John Leech, Bioprocessing and Fermentation Technologist, Teagasc Agriculture and Food Development Authority, Republic of Ireland

Industrial bioproduction — which uses living cells to produce key molecular products at scale — is in itself a whole universe of molecular biology jobs. The same basic science can lead you to a key therapeutic that will change someone’s life or to a crisp, balanced glass of beer or wine. The career possibilities are endless.

SOMB guest Kelly Tretter is a trailblazing microbiologist with 30+ years of experience in the male-dominated beer brewing industry. Her day-to-day duties as a quality specialist include monitoring products and materials for safety, quality, and taste, drawing on scientific data to understand which contaminating bacteria might affect a beer’s flavor profile. She uses core molecular biology techniques like PCR, chromatography, and more in her work.   

Yeast is the fermenting organism behind the taste of your favorite beer, but of course there’s a whole, vast world of other microorganisms out there.  

Guest scientist John Leech bridged into fermentation science from evolutionary biology, where he had become interested in the strange longevity of bats (fun fact: they live much longer than their body size suggests they should!) and the role of the microbiome in human health and aging.  

Many consumers try to boost their microbiome diversity through commercial probiotics containing 1-12 strains of bacterial species, says Leech, but that’s a drop in the bucket compared to how many species may coexist within natural, healthy microbiomes. Leech is interested in using naturally probiotic-rich, fermented foods to enhance health and is examining which ones can demonstrate reproducible benefits.  

Beyond the food and beverage space, fermentation science also extends into career possibilities in biofuel production, pharmaceutical manufacturing, skincare and cosmetic design, and more.

Cheers to molecular Biology – Speaking of Mol Bio

While the end product is quite different, brewing beer is not all that different than many other bioproduction processes used in the lab and industry. Both require skills, experience, and the right QC/QA methods to control and monitor the starting materials and the entire process, all the way to that bottle of suds you might be thirsty for. Steve and Gabriel talk with Kelly Tretter, a microbiologist with more than 30 years of experience in the brewing industry, to discuss brewing at the molecular level. The passion of all three for beer is evident in the conversation, which spans from the basics of the brewing process all the way into the use of molecular methods (e.g., PCR, sequencing, HPLC, GC/MS, ICP, etc.) used to test and monitor starting materials and in-process samples. You’ll leave with an elevated appreciation of what brewers do, and you’ll likely be ready for another pint too!

The value of community – your microbiome – Speaking of Mol Bio

The history of fermented foods like beer, bread, and other foods can be traced back thousands of years to ancient civilizations in China and Egypt. This ancient technology was originally used to preserve foods when refrigeration was not an option. While less common in modern industrialized civilizations, we’re now realizing that fermented foods play a major role in gut microbiome diversity, which is a biomarker for overall health. Join our conversation with Dr. John Leech, Technologist at Teagasc in County Cork, Ireland to learn all about the history and how cutting-edge technologies are being applied to research in food fermentation. John shares his story of how he found this field of research and how he’s now headlong into striving to understand and harness the power of fermented foods. We learn about the complex microbial communities that define and deliver the health benefits of these foods, but we also hear about how this biological complexity makes them inherently irreproducible. Foods like kimchi, sauerkraut, kombucha, tepache, milk kefir, and water kefir are produced from fermentation, facilitated by complex communities of microbes. Consumption of fermented foods can alter our gut microbiome, which has been shown to affect obesity, inflammation, longevity, and efficacy of drug treatments. John and his team are using qPCR, NGS, and other methods to characterize the microbial consortia used to produce these foods. They’re now working to figure out how to simplify the consortium while still delivering health benefits, all while making the process reproducible and scalable Subscribe to get future episodes as they drop and if you like what you’re hearing we hope you’ll share a review or recommend the series to a colleague.  Visit the Invitrogen School of Molecular Biology to access helpful molecular biology resources and educational content, and please share this resource with anyone you know working in molecular biology.  For Research Use Only.

Scientific marketing in the century of the biotech revolution – Speaking of Mol Bio

Most scientists start their education and careers with a vision of working in the lab to discover great things and drive innovation. However, we don’t all end up loving the actual lab work portion of science. What non-lab career options exist to utilize molecular biology knowledge and skills? Well, according to our guest, Jason Amsbaugh, Founder and CEO of Samba Scientific, the career options are far more plentiful than you may think. Scientific marketing, according to Jason, is one such role that is all about understanding the science, first and foremost, but it’s also about effective communication. Essentially, he and his team have to balance technical knowledge with creativity to understand a wide variety of client products and services, uncover the core benefits of those products and services, and then develop marketing content that holds water when put in front of scientists who are, according to Jason, “skeptical” by nature. Our conversation covers Jason’s own career path, current trending technologies, the use of AI in both science and marketing, ethics in scientific marketing, and more. If you’ve ever wondered about what roles exist outside of the lab and how to move your career in that direction, this episode is for you. If you’re happy in your lab-based career but want to have a bit more faith in those selling you the products you use, this episode is also for you!

Food safety and biosecurity is another large field that addresses the more insidious members of the global microbiome – disease-causing agents and toxins.  

On the human health side, molecular biologists can serve as infectious disease experts monitoring disease risk and spread via molecular diagnostics. Through the COVID-19 pandemic, molecular biologists have been key in developing tests and treatments and in surveilling wastewater for SARS-CoV-2 virus levels.  

Some molecular biologists become biosafety experts helping to deliver safe facilities, trainings, and best practices for handling dangerous pathogens, while others pursue national security policymaking with their deep scientific understanding.  

On the side of food safety and security, scientists like guest and public servant Beverly Wood work to protect our food, economic, and health systems by monitoring livestock and food supplies for contamination, illness and potentially zoonotic diseases like avian and swine flus, chronic wasting disease, bovine spongiform encephalopathy, foodborne illnesses, and more.  

Biologists in this space can also explore high-level food system resilience to pandemics, climate change, invasive pests, and more. These efforts often begin at the molecular level, such as using genetic engineering to develop more resistant plants, engineer remediating symbionts, or interrupt a pest population’s reproductive cycle.
