Jenna Roller-Knapp
Jenna specializes in aquatic ecology. She obtained her Bachelor of Science in Biology from the University of Wisconsin-River Falls, and her Master of Science in Environment and Natural Resources- Fisheries and Wildlife from the Ohio State University. Growing up near the thousands of lakes in Minnesota, using her SCUBA certification for work and play, and pursuing undergraduate and graduate research focused on wildlife in wetlands (the role of functional diversity in biotic resistance of non-native fishes and invertebrates in Lake Erie coastal wetlands) has developed a deep passion and knowledge base for investigating, protecting, and restoring aquatic-terrestrial interfaces. This is especially important for the great numbers and wide variety of wildlife species that rely on such habitats. Jenna is ODNR-certified to perform freshwater mussel surveys in Group 1 and 3 streams and EPA certified as a Macroinvertebrate Level 3 Qualified Data Collector (sample collection and data analysis). She enjoys contributing her aquatic ecology focus to the MAD team to support and expand the company’s capabilities toward ecological surveys and restoration projects in the Midwest. Ext. 17

Ellie Zinsmeister
Ellie is a graduate of the Ohio State University, where she studied environmental science with a specialization in ecosystem restoration. She has lived most of her life in Ohio and grew up visiting Lake Erie in the summers. Through these experiences, she has learned how important it is to maintain healthy ecosystems and biodiversity. Having gained fieldwork and conservation ecology experience through previous positions with the USDA and Preservation Parks of Delaware County, Ellie has built her skills in ecosystem management, especially with wetlands. Restoring wetlands and educating the public on their importance is a high priority for her, and she understands to have healthy wetlands, the surrounding ecosystems (e.g., forests and prairies) need to be protected and carefully managed, too. The relationship between these natural systems is something Ellie strives to understand and help improve. Outside of work, Ellie is an amateur birder and native plant gardener, hoping to attract many native birds and pollinators to her property. Working with MAD Scientist Associates, Ellie hopes to obtain training and certifications and eventually master the process of restoring ecosystems from start to finish.
Alan Coburn
Alan graduated from the Ohio State University in 2018, receiving a Bachelor of Science in Environmental Science and Natural Resources with a specialization in Ecosystem Restoration. Growing up in Northeast Ohio as an active outdoor enthusiast, he developed a deep respect and curiosity for nature. This appreciation for nature only further developed during his time as an undergraduate researcher studying the effects of restoration actions on plant communities in coastal Lake Erie wetlands. Alan joined the MAD team with this background as well as various other experiences in ecological assessments, restoration, horticulture, and land management. At MAD Scientist Associates, he is excited to share his knowledge and experience while continuing to learn and grow in the areas of invasive species management, ecological surveys, and restoration.
