Jenny Adkins, Professional Wetland Scientist (Specializations: Botany and Environmental Education)

Jenny received her B.S. in Biology and Masters in Education from Wright State University in Dayton, Ohio. Through her years of schooling and work experience, Jenny has become skilled in plant identification, restoration planting plans, and management practices for invasive species control. She is proficient in completing detailed botanical surveys such as Ohio's FQAI and VIBI. She is a Professional Wetland Scientist, certified delineator with ORAM training, as well as a surveyor for running buffalo clover. She utilizes her master's in education by working with municipalities and area school districts, developing outdoor programming and environmentally focused curriculum. She also works directly with teachers and other local educators to enhance their approach in utilizing the outdoors and wetlands in their classrooms.

Lindsay Hanna, Project Scientist

Lindsay received her B.S. in Environmental Science from Bowling Green State University, and her M.S. in Natural Resources and the Environment with an emphasis in Terrestrial Ecosystems from the University of Michigan. She is a Certified Wetland Delineator and has spent much of her career delineating wetlands across the United States. In addition to wetland work, Lindsay has conducted T/E surveys and natural resource surveys, as well as performed sampling for water quality and harmful algal blooms. She has a wide variety of project experience, from environmental compliance auditing to NEPA biological and environmental assessments to environmental sampling.


Mary Skapof, Environmental Scientist (Specializations: Permitting & Environmental Education)

Mary received her B.S. in Environment and Natural Resources with a specialization in Environmental Education from The Ohio State University. She was a former Naturalist with Columbus Metro Parks and has extensive experience with surface water permitting including NPDES permitting as well as Storm Water Pollution Prevention Plan (SWP3) and Spill Prevention, Control, and Countermeasure (SPCC) plan compilation. She is also a Level 2 Qualified Data Collector specializing in Benthic Macroinvertebrate Assessment and is ORAM trained. She utilizes her diverse background to not only assist clients with interpreting the complexities of environmental regulations, but to also assist area schools and educational programs with incorporating environmental education into their lesson planning.

Jim Palus, Environmental Scientist (Specialization: Wetland Restoration)

Jim received his B.S. in Environmental Science and M.S. in Environment and Natural Resources from Ohio State University, both degrees specializing in ecological restoration. His undergraduate work focused on aquatic ecology, where he studied harmful algal blooms in a community-managed lake in central Ohio. For his graduate degree, his field work shifted to the Wayne National Forest, where he studied community assembly and successional dynamics. Jim has volunteered with The Nature Conservancy and has served on the board of Friends of the Lower Olentangy Watershed. More recently, he ran a volunteer tree planting program for the City of Columbus Recreation and Parks Department, assisting the Branch Out Columbus campaign to expand Columbus’s urban tree canopy. Jim is a certified SCUBA diver and is trained in the Ohio Rapid Assessment Method (ORAM) for wetlands. He also has been approved as a Certified Ecological Restoration Practitioner-in-Training (CERP-IT) with the Society for Ecological Restoration. 


Jenna Odegard, Environmental Scientist (Specialization in Aquatic Ecology, Fisheries and Wildlife)

Jenna is a Minnesota native who 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 on the thousands of lakes in Minnesota, pursuing undergraduate and graduate research in wetlands (the role of functional diversity in biotic resistance of non-native fishes and invertebrates in Lake Erie coastal wetlands), and actively using her SCUBA certification for work and play has developed a strong interest and deep passion 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. She is excited to contribute her biological focus to the MAD Scientist Associates team to support and expand the company’s capabilities and pursue ecological survey and restoration projects in the Midwest.
