About Me

I’m Tess Eidem, Ph.D., a skilled microbiologist with expertise in communication, entrepreneurship, and management. I have a commitment to my team to stay positive in the face of ambiguity and tap into my technical STEM skills and cross-cutting experiences to ensure projects are delivered successfully.

Check out My Portfolio to see some of my creations, and read My Blog to see what projects I’m working on. You can also learn more about my family-owned business, North Country Food Lab to see what kind of microbe wrangling my husband and I are up to. Please Contact Me if you have questions, comments, ideas, or suggestions!

As a kid, what drew me to science was pretty ordinary stuff. I asked simple questions like, “Where are those ants going and what are they doing?” and, “Why to the leaves change color every year?” The more questions I found answers to, the more follow-up questions I had, and there was always so much more to learn. In college, I started learning by exploring in the laboratory and asking questions no one had answers to. I found that I loved pushing the boundaries of human understanding, and I wanted to push more—so I went to graduate school to become a trained scientist.

As a graduate researcher, I worked to find innovative ways to kill “bad” bacteria like Staphylococcus aureus, discovering new antibiotic molecules and fighting antibiotic resistance. I continued to conduct research and started branching into science communication and teaching to feed my creative side. I left the bench to gain additional training in project management and started North Country Food Lab to wrangle microbes with my husband, make delicious fermented foods, and help others grow their own healthy microbiomes. As a professor, I connected my experiences as a microbiologist, communicator, leader, and entrepreneur to prepare students with the skills and knowledge to combat 21st-century challenges to human health and the environment.

Interests and Activities

Although we can’t see microbes and molecules, they are all around us and essential for life on Earth. I am fascinated with how these tiny things make a big impact on all of us, and I continue to explore how we can utilize these tiny organisms to protect and improve our world.

Microbes are also a pretty big deal when it comes to food—from beer to sauerkraut to cheese, they bring the unique flavors and “friendly” bacteria we want in our gut. Experimenting in the kitchen is a fun pastime for my family—the best experiments are those you can eat!

I love science, but I like to exercise other parts of my brain too. I love singing, playing guitar, and writing music. Spending time in the great outdoors and practicing yoga are ways that find my center, and I’m happiest with many friends and puppies around.
