Tracie Baker

Principal Investigator and Director

Dr. Baker has substantial academic training and research in developmental biology, environmental toxicology, genetics, and animal health. Her academic training has been multidisciplinary in nature with an interest in toxicology beginning as an undergraduate at Cleveland State University, where she investigated water pollution effects on zebra mussel survival and behavioral ecology. She earned her Master of Science at the University of Alaska – Fairbanks while researching genes involved in toxin production by harmful algal blooms and bacterial species. After earning her DVM (University of Wisconsin – Madison) and a certificate in fish health medicine from the State of Wisconsin, she was an assistant researcher investigating clinical improvements in fish medicine before accepting an NIEHS-funded postdoctoral position that evolved into a PhD program at UW – Madison under the mentorship of Dr. Dick Peterson. Her research was the first to show transgenerational inheritance of disease using a zebrafish model. In 2013, she competed successfully for an NIH K01 award through the National Center for Advancing Translational Sciences (NCATS). Dr. Baker found that low level, dioxin-induced decreased fertility across multiple generations following early developmental exposure is mediated through the male germline, and has been invited to present these findings at several national and international conferences, including at several workshops hosted by the National Institutes of Health (NIH). She started her own laboratory at Wayne State University in 2016 and transitioned to a tenured Associate Professor position in the Department of Environmental and Global Health at the University of Florida in August 2021. In this time, the WATER lab has published primary articles that highlight our knowledge and skills uncovering the critical genes and epigenetic regulation underlying adverse health endpoints and provide critical insights into transgenerational, environmentally induced disease. Recent publications include the investigation of single-cell transcriptomic changes involved in EDC-induced infertility, the occurrence and effects of endocrine disruption due to environmental contaminants we measured in Detroit waterbodies, exogenous factors linked to the development of childhood leukemia, occurrence of microplastics in drinking water and the consequential impact on human health, evaluation of microbiome changes due to drinking water filtration, and the use of novel assay systems to evaluate health effects of volatile organic chemicals. As a previous NCAA Division I swimmer, Tracie enjoys being a faculty advisor for the WSU Swimming and Diving team. In her spare time, she enjoys spending time with her wife, daughter, and their two dogs, participating in open water swim events and triathlons, traveling, and being outside.

Danielle Meyer

Post-doctoral fellow

Danielle is a postdoctoral research associate in the Department of Environmental and Global Health at the University of Florida. In 2021, she earned her Ph.D. in Pharmacology at Wayne State University, after majoring in Biology and Psychology with a minor in Neuroscience from Hope College in 2015. Since joining the WATER lab in 2016, her doctoral (and ongoing) research has explored the lifespan and legacy health effects of developmental exposure to environmental endocrine-disrupting toxicants, including TCDD (dioxin), lead, and nanoplastics. Her research goal is to use the zebrafish model to look at the specific timing of molecular events during early development that become dysregulated by endocrine disruption, leading to effects ranging from infertility to neurological dysfunction later in life and in following generations. Outside of the lab, she enjoys reading, music, podcasts, theater, researching and exploring new places, and cuddling all available fuzzy animals.

Mallory Llewellyn

Post-doctoral fellow

Mallory obtained her bachelor’s degree in Physiology with a minor in Chemistry from the University of Washington in Seattle. She worked in clinical research at Fred Hutchinson Cancer Center where she used CRISPR and Base Editor technologies to treat blood diseases. She has long been interested in the negative health effects of pollution and drinking contaminated water. This fascination pulled her to Florida to study environmental toxicology in Dr. Baker’s lab. With a PhD in Physiological Sciences, she is quantifying and characterizing microplastics and PFAS in the Great Lakes. This data will inform her laboratory zebrafish study where she will test the effects of ingesting microplastic fibers in combination with PFAS. In her free time, she enjoys gardening, swimming, mushroom hunting, and reading with her cat Bellatrix.

Mackenzie Connell

Post-doctoral fellow

Mackenzie joined the WATER lab in 2017 while pursuing her B.S. in public health with a minor in sociology. She then went on to earn a Master of Public Health Degree from Wayne State University with a concentration in public health practice. Mackenzie has had the opportunity to learn about environmental health and contribute to health research in her time with the WATER Lab, Michigan Antibiotic Resistance Reduction Coalition, and Henry Ford Health System. Combining her background and education in Public Health Analytics, Mackenzie built on these foundational skills during her PhD program in Public Health at the University of Florida. Mackenzie has a passion for maternal and reproductive health and will continue to investigate the environmental stressors that affect organisms during critical reproductive windows. When she’s not in the lab, you can find Mackenzie on the water, reading, or enjoying quality time exploring Florida with her husband and dogs, Ari and Pelican.

Emily Kintzele

Graduate student

Emily received her B.S. in Biology with a minor in Wildlife Ecology and Conservation from the University of Florida. She has a diverse research background from working in a small animal veterinary hospital with dogs and cats to studying conservation biology and animal behavior in Kenya with elephants and giraffes. Emily’s work with zebrafish in the WATER lab started as an undergraduate student and has led her to this program where she is working towards her PhD in Public Health with a concentration in One Health. Outside of the lab she enjoys playing tennis, painting, and spending time with her dogs Jack, Diamond, and Heart.

Alyssa Meyers

Graduate student

Alyssa graduated from the University of Tampa with a B.S. in Marine Science and Marine

Chemistry and a minor in Sustainability in May 2025. Her undergraduate work focused on

drivers of harmful algal blooms in Tampa Bay. This led her to an undergraduate research

experience at Mote Marine Laboratory where she researched the effects of potential

harmful algal bloom mitigation techniques on benthic invertebrates in their ecotoxicology

lab. At UF , Alyssa is pursuing a PhD in Public Health with a concentration in environmental

health. She hopes to do work on contaminants that connect to both human and

environmental health. In her free time Alyssa enjoys scuba diving, bouldering, lifting

weights, and lounging with her two cats.

Emma VanderMeulen

Graduate student

Emma received her B.S. in Genetics from the Michigan State University. She then moved to Portland, Oregon where she worked as a medical assistant for several years before returning to school. Emma then completed her MPH at Oregon Health & Sciences University-Portland State University School of Public Health. During her time completing her master’s she began researching water quality standards and regulations along with contaminants of emerging concern, specifically pharmaceuticals and personal care products. She will continue this work and build her skills as an academic researcher as she works towards her PhD in Public Health at the University of Florida. During her free time, she loves hiking, camping, paddleboarding, and spending time with her cat Hestia.

Abby Hahn

Lab Manager

Abby graduated from the University of Florida (Go Gators!) with a B.S. in Biology and a minor in Asian Studies. She joined the WATER lab team shortly after graduating in 2023 and has since enjoyed taking a deep-dive into the world of water. In her free time, Abby likes to read, garden and play soccer.
