Stars to Starfish Internship

The Stars to Starfish program enlivens the science curriculum, bringing to the classroom hands-on experiential learning.  Students build personal knowledge and appreciation for the significance and importance of maintaining a healthy environment while maintaining delicate ecosystems in their own classrooms and school state-of-the-art AquaDome. 

Their passion translates to inspiration as 5000 of Sarasota County’s elementary students journey through the AquaDome each year.  Riverview High School’s science education program is unparalleled in its diversity of subjects to explore and the quality and rigor of the educational experience.

Meet our current year interns.

2020/2021 Stars to Starfish Interns

Marine Science Club

The Marine Club is an after school club that is dedicated to protecting, raising awareness, and having fun with the ocean and marine life.  Membership is open to any Riverview High School student.  Members of the club pay $10/ school year in dues and an additional $10 for a club shirt.  The club meets weekly to: 

  • organize on campus outreach and events,
  • plan attendance at community events that encourage responsible stewardship of our local Sarasota community
  • enjoy guest talks from local scientists,
  • trips to local research and management agencies and
  • a fun, annual trip to Sea World to explore their education and research program!

Staff Backgrounds and Bios

Glenn Wachter
Assistant Principal, Riverview High School


Katrin Rudge, Co-Director of Aquascience Programs

Katrin Rudge received her Bachelor of Science degree from the University of Maryland in 1988 where she took courses taught by Dr. Eugenie Clark, founder of Mote Marine Laboratory. This is where she developed her fascination and interest in sharks. She continued her graduate work and earned a Master’s of Science in 1992, through University of Maryland’s Marine Estuarine Environmental Sciences Program (MEES). Her professional experiences include a research assistantship with the Smithsonian Environmental Research Center (SERC), establishing her own business Chesapeake Workshops Unlimited, where Katrin coordinating numerous technical & scientific workshops and conferences for the Chesapeake Bay Program before she moved to Sarasota in 2001.Currently, Katrin is the Director and founder of Riverview’s Aquascience Program, as well as co-director of the Stars to Starfish Program at Riverview High School in Sarasota, FL. She teaches Marine 1 Honors and the IB Career Pathway Marine Science. Katrin has established valuable partnerships with Mote Marine Laboratory, New College, the University of Florida and Sarasota Bay Watch and Sarasota County Government to strengthen the research components of this Program. The Stars to Starfish program evolved as a way to offer outreach and hands-on field trip experiences to elementary and middle school students from around the county who visit Riverview’s Planetarium and are then escorted by her students to the Aquadome where they learn about and view many different marine organisms and develop and appreciation for environmental stewardship and keeping our waterways healthy and pristine for these creatures. Katrin is always searching for that next interesting project for her students.

Frank Gangi, Aquaculture Facilities Manager
Frank earned an AA from State College of Florida and was a 1984 graduate of Riverview High School. He started working at Mote Marine Lab from 1986-1989, first working in the Aquarium and then moved over to the Laboratory involved with collections, maintaining the shark tank and getting to know some really good people while gaining hands on knowledge. Frank also took part as a research diver gathering data in the Bahamas on the Sand Tilefish, “Reproductive behavior and social organization in the sand tilefish, Malacanthus plumeri” under the direction of Dr. Eugenie Clark, Joan S. Rabin and Susan Holderman.

Frank started working at Marinco Bioassay Laboratory, Sarasota in 1992 – 2007, initially overseeing all facets of a growing toxicity lab. Once the lab relocated and expanded he took over as lead of the Aquaculture Department, designing all the systems needed to breed and maintain the indicator organisms used in WET (Whole Effluent Toxicity) testing.

In 2006, Frank partnered up and started a company called EcoAquatics also located in Sarasota, devoted to culturing and supplying of a species of mysid, Americamysis bahia, used extensively in research and as a live feed. This facility is still up and running and is currently in a stage of expansion after recently relocating.

In 2017, Frank went full circle and returned to Riverview High School accepting a job as Aquascience Facilities Manager overseeing the aquaculture program, establishing a clownfish breeding program used to insert funds back into the program, updating the Aquadome and basically trying to do my part in creating one of the top high school aquaculture programs in the nation.
