Cassie Volker-Rusche, Research Assistant

Cassie Volker received her B.S. (2013) in biology from Northern Kentucky University and her M.S. (2016) in biological sciences from Florida Atlantic University. Cassie is originally from Cincinnati, OH where she grew up loving animals of all kinds. She has always been interested in their behavior and why they do what they do. During her undergrad she was involved in undergraduate research examining parental care behavior in the Carolina Chickadee, a small songbird. After being involved in this research, Cassie knew she wanted to pursue her graduate degree, and so she found Dr. Denise Herzing and the Wild Dolphin Project. She was working on her master’s thesis, investigating spotted dolphin aggressive behavior, and helping out on the boat from 2014-2016. She moved back to Cincinnati, OH briefly but decided she missed the dolphins, Florida’s beaches, and the warmer weather! Cassie is now back working with us as our Research Assistant and will be out in the field on the boat a lot this summer!

Hayley Knapp, Masters Student

Born and raised in Wichita, KS, Hayley fell in love with dolphins when she was four years old after her first trip to SeaWorld. Having grown up sailing and swimming, she has always loved the water and knew she had to be a strong swimmer to work with dolphins in the future. So, she became a competitive swimmer and competed for William Jewell College, where she received her B.A. in biology and a minor in Spanish in 2020. Despite being landlocked, Hayley found ways to work with various wildlife in college, from walking dogs at a local pet shelter to volunteering with the adorable penguins at the Kansas City Zoo. Hayley first heard about the Wild Dolphin Project in 2012 after watching Dr. Herzing’s TED talk “Could We Speak the Language of Dolphins?” At the time, Hayley was in middle school, but she knew she wanted to be a part of the amazing team involved in Dr. Herzing’s research. In 2019, that dream became a reality when she received a grant from Jewell to intern with the Wild Dolphin Project and had a blast learning about wild dolphins. Hayley returned for a second internship in 2021 and returned as a crew member in 2022. Now, Hayley is a master’s student at Florida Atlantic University for the WDP, where she is studying dolphin genetics, such as paternity, with Dr. Green.

Lori’s first introduction to the Wild Dolphin Project was in the 1980’s as a trip participant. She found the experience so exciting and interesting that she returned the following year as a volunteer crew member for two trips. Over the years she has followed the Wild Dolphin Project and when a job relocation brought her to the Jupiter area in 2017, she reconnected with WDP as a volunteer.  Her love of dolphins and all things marine-related and great respect for the research work Dr. Herzing and WDP does, inspires her to continue as a volunteer and participate on the Community Advisory Board.

Rita Gohlke

“If sea creatures could appoint ambassadors, they might choose dolphins to forge bonds of understanding between humankind and themselves… “,  By Sylvia A. Earle- Wild Oceans - American’s parks under the sea, National Geographic Society 1999. This quote is one of Rita's favorites and represents what the The Wild Dolphin Project, with the guidance of Dr. Denise Herzing, is working towards.

Rita's first encounter with the The Wild Dolphin Project was in the 2018 after she moved to Stuart.  She was told about this non-profit group that goes out and does scientific research on the wild Atlantic Spotted Dolphins and that ordinary people like herself could participate in.  During that trip, she was educated on exactly what they were doing and how long this endeavor has been going on. It was an eye opening experience for her.  After that trip, she was hooked and decided to volunteer and contribute anyway that she could.  With 37 years experience in retail, she knew that she could use her past career to assist in raising money, participating in events and do whatever needs to be done.   As a diver and lover of all living creatures of the oceans, one of her goals as a retiree was to contribute to the greater good in anyway that she can and the Wild Dolphin Project has provided her this opportunity.
