About Us

On October 1, 2018, Jill Arnold and Brent Whitaker launched ZooQuatic Laboratory LLC, a Clinical Pathology and Water Quality laboratory, though ZooQuatic is truly an old lab with a new name. In 1991, Jill, a certified medical technologist, and Brent, an exotic/aquatic animal veterinarian, created a laboratory at the National Aquarium in Baltimore to support the care of the Aquarium's fish, reptiles, birds, amphibians, invertebrates, and mammals. In 2000, the laboratory relocated next door to the University of Maryland's Institute of Marine and Environmental Technology (IMET) which allowed for additional collaborations with world-renowned scientists in the development of new and innovative technologies and techniques. Though now a private commercial enterprise, ZooQuatic Laboratory continues to support the National Aquarium and IMET's Aquaculture Research Center while also offering our services to zoos, aquariums, universities, researchers, aquaculture facilities and others in need of accurate and affordable water quality and clinical pathology testing, as well as anatomic pathology services for vertebrates and invertebrates.

Our Mission


To provide unique expertise and specialized testing of exceptional quality for extraordinary species and the environments in which they reside.

Brent Whitaker MS, DVM

Partner, CEO

As a kid, I trekked through fields and streams from Maryland to Maine, turning over every rock and looking under every log to see what creatures lived there. After studying biology at the Colorado College, I worked as a technician in the Environmental Systems Lab at Woods Hole Oceanographic Institution. It was there that I saw my first Aquavet student and decided I had found my future. I was going to be a veterinarian that specialized in aquatic animals and environments. I left the Northeast and headed to the University of Florida where I received my Master of Science degree in aquatic toxicology (1986) and a Doctorate in Veterinary Medicine (1988). I became an Aquavet student in 1987. After a year in a small animal private practice, I joined the National Aquarium as their first full-time staff veterinarian and 2 years later I became the Director of Animal Health leading a newly created veterinary medical team. In 2005, I was appointed to lead their Animal Science and Welfare which included husbandry, veterinary medical, laboratory, marine animal rescue, dolphin discovery, and research programs. Together with a staff of 80+ individuals we ensured the health and welfare of over 20,000 animals and provided memorable experiences for all visitors to the National Aquarium. In October of 2018, after 28 years with the National Aquarium, Jill Arnold and I created ZooQuatic Laboratory, an independent company operated by former Aquarium lab staff, that now serves all zoos, aquariums, specialty practices, and individuals. When not at the lab, one can usually find me practicing aquatic animal medicine and working with zebrafish at the University of Maryland, or at a local animal rescue shelter performing surgery and providing care.

Jill Arnold MS, MLS(ASCP) CM

Partner, Managing Director of Lab Services

I studied animal science and biology at Purdue University while working part-time in a veterinary hospital in my home town of Fort Wayne, IN. After graduation, I completed a 12-month internship at Parkview Memorial Hospital and obtained my medical technology certification. I was very fortunate to be chosen as an intern in the pathology department at the Smithsonian’s National Zoo where I spent an amazing year in Dr. Montali’s lab, and then I was off to learn about aquatic animals at the National Aquarium. After spending many hours deciphering elasmobranch blood smears, I opted to do a master’s degree in biomedical research at University of Maryland where my thesis topic was standardizing complete blood cell counts for sharks. I have had the privilege of applying the skills I learned in medical laboratory science to the challenging field of aquatic animal health. I love all aspects of the lab and am especially interested in hematology of fish and elasmobranchs. After managing the clinical and water chemistry laboratories at the National Aquarium for over 20 years, Dr. Brent Whitaker and I set up ZooQuatic Laboratory in October 2018, which is the former Aquarium’s lab and staff now operated as an independent company. In addition to my duties in the laboratory, I enjoy teaching hematology workshops. I also serve as Secretary for the Quality Assurance for Laboratory Standards Committee for the American Society for Veterinary Clinical Pathology and have been a member of this committee for 12 years. When I’m not working or fishing for blood samples, I enjoy hiking with my husband and dogs.


Kim Gaeta

Water Quality Technologist

After graduating from the University of New Hampshire with a degree in Marine and Freshwater Biology, Kim followed the advice of a neighbor and started volunteering at the National Aquarium in Baltimore to gain experience as most job interviews were asking the same thing- "what have you done other than school?" During her volunteer time, Kim was responsible for taking dissolved oxygen measurements in the larger systems as well as monitoring general water quality. An opportunity presented itself and Kim was hired on full time as a water quality technician. Projects ranged from monitoring pH levels of concrete samples used in the Amazon River Forest exhibit to bacteria cycling in seahorse and frog exhibits. Over her 19 year career at National Aquarium she says "there was never a dull day. You never knew what the samples were going to show for water quality values." ZooQuatic Laboratory formed and Kim joined the group as the primary analyst for water samples. "I'm looking forward to working with various institutions in looking closely at their water quality." In her spare time, Kim enjoys outdoor adventures with her two children and husband.

Morgan Shapiro

Clinical Lab Technician

Growing up in Maryland, Morgan loved exploring the water, the oceans, and the animals within them. During her undergraduate, she had the opportunity to study in Queensland, Australia at James Cook University, right off the Great Barrier Reef. There she developed her love for scuba diving and scientific research, as well as her love for camping and surfing! After returning to New Orleans to finish her undergraduate degree in Public Health and International Development, Morgan decided to add Environmental Studies to her degree, and was able to concentrate on marine biology and the integration of the health of the seas and the animals within, for a true One Health approach to her learning. She graduated from Tulane University in 2021, and since then has been involved in multiple research projects studying topics from the health of the Baltimore harbor and the Chesapeake Bay to oyster aquaculture and restoration efforts. Now at ZooQuatic Lab, Morgan has had the opportunity to return to Maryland to explore the Animal Health side of One Health and develop her knowledge of animal and wildlife care. When she’s not working, she loves to take her dog to the beach, try vegan, gluten free snacks, and spend time with her family.


Dr. Alisa “Harley” Newton, VMD, Dipl. ACVP

Pathologist

Dr. Newton received her veterinary degree and anatomic pathology training from the University of Pennsylvania, School of Veterinary Medicine and is a Diplomate of the American College of Veterinary Pathologists. Following her pathology residency, she completed the Jane and Marshall Steel Pathology Fellowship at the Zoological Society of San Diego. During her career she has served as the Director of Pathology at the Philadelphia Zoo, Senior Pathologist at the Wildlife Conservation Society (WCS), and a Veterinary Pathologist for Disney’s Animals Science and Environment. While at WCS Harley transitioned from being solely a veterinary pathologist to be the Head of Aquatic Health. In that role she provided medical care, water quality laboratory management and diagnostic veterinary pathology services for the fish (elasmobranch, teleost), invertebrate (terrestrial and aquatic), marine mammal, bird and reptile collections at the New York Aquarium and 4 WCS run zoos in New York City (Central Park Zoo, Prospect Park Zoo, Queens Zoo, Bronx Zoo). Harley has a passion for wild shark and ray populations, which led her to develop with WCS’s New York Seascape Program and other regional partners an in situ elasmobranch health field research program focusing on Northwest Atlantic species. It was through this work that she was invited to join the not-for-profit OCEARCH first as an expedition veterinarian and scientist, ultimately assuming the role of Chief Veterinarian/Senior Veterinary Scientist in 2022. Along with sharks and rays, Harley has a passion for invertebrates, and still greatly enjoys working with terrestrial animals great and small. She is looking forward to collaborating with the wide variety of institutions and organizations that might use ZooQuatic Laboratory’s Pathology Services.
