Principal Investigator

Dr Taylor Chapple (he/him)
Research
Over the past 15 years, Taylor has been studying sharks and other large marine predators around the world focused on their movements, behaviors and population dynamics. From South Africa to Australia to California, using state of the art technology, he electronically tags animals to gain insights into their lives when we aren’t there to observe them. At OSU, Taylor studies the sharks off our coasts and works with local communities to better understand sharks in Oregon. Relatively little is known about how White, Salmon and Sevengill sharks affect our coastal ecosystems, but Taylor and the BFL plan to change that.
Bio
Taylor grew up in the great state of Ohio on the shores of Lake Erie. He received his BA from Boston University in biology with a concentration in marine science in 2001. Taylor then worked designing experimental fishing nets to limit bycatch of New England and taught marine science aboard a sailboat in the Puget Sound. In 2002 he first began working with sharks off the coasts of Florida and throughout the Gulf of Mexico. Taylor received his Ph.D in 2009 from the University of California, Davis, developing ways to estimate and assess shark species with little data. At UCD his work focused on the Common Thresher shark and the White shark. In 2010 Taylor began an appointment with the Max Planck Institute in Germany, studying the energetics and behavior of highly nomadic species. He also studied how sharks navigate by developing a magnetic tag, which can manipulate the ambient magnetic field around a shark. In 2012 Taylor began a second post-doctoral appointment with Hopkins Marine Station of Stanford University. At Stanford Taylor worked on a continuing assessment of white sharks as well as their behavior and movements. Taylor started at OSU in 2019 and currently runs the BFL at OSU’s Hatfield Marine Science Center.
If Taylor had spare time it would be a miracle, because when he’s not out chasing sharks he’s chasing his two very energetic kids.

Alexandra McInturf, PhD (she/her)
Bio:
Alex McInturf is a Research Associate in the Big Fish Lab. Raised in Cincinnati, Ohio, Alex’s interest in sharks began when she was very young. She credits her initial fear of sharks and unfamiliarity with the ocean for prompting her exploration to better understand this environment. While in Ohio, she volunteered at the local Newport Aquarium (KY) and read every book she could find on sharks, skates, and rays. She then attended Williams College for her undergraduate education, where she enrolled in the Williams-Mystic Coastal and Ocean Studies program to learn a more interdisciplinary approach to studying the sea. Following graduation, she was an intern with Oceans Research (South Africa) and the Bimini Shark Lab (Bahamas), where she studied white sharks, tiger sharks, hammerhead sharks, and sandtiger sharks. She obtained her PhD in Animal Behavior from the University of California, Davis, for which she examined physiology, behavior, and distribution of basking sharks, sevengill sharks, and salmon. In addition to research, Alex is an avid science communicator, soccer player, trail runner, reader, baker, and dog mom.
Fun facts:
Alex has an English degree from Williams College.
Research interests:
Alex is interested in the movement and behavior of sharks and their relatives, and how these are influenced by biotic (living) and abiotic (non-living) factors in the environment. She uses a combination of methods, including stomach content analysis, biologging, and spatial modeling, to explore these topics in a wide variety of threatened or data deficient species. Her current work in the Big Fish Lab spans a wide range of topics, but includes research on the diet and habitat use of salmon sharks, the movement of Pacific spiny dogfish, distribution of Chinook salmon, and the social lives of basking sharks in Ireland.

Graduate Students
Jessica Schulte (she/her)
Bio
Jess graduated with honors from the University of Florida in 2013 with a degree in Environmental Science focusing on climate change and other global anthropogenic impacts. She interned in the Florida Museum of Natural History’s shark lab, working in the International Shark Attack Files, as well as the US Geological Survey’s Benthic Ecology Lab, processing deep sea coral samples for stable isotope analysis. This work led to full-time opportunities in USGS’s Invasive Fish lab where she worked across a variety of research including ecophysiology, foraging ecology, and genetics of non-native species in Florida. She then served for 2.5 years in the Peace Corps where she collaborated with communities on coastal resource management and conservation in the Philippines. After returning to the States, she worked at the State Department in Washington DC, handling international climate change programs and diplomacy before starting graduate school in Fisheries Science at Oregon State University.
Jess was awarded the 2021 Oregon Sea Grant Robert E. Malouf Marine Studies Scholarship, the 2021 Marine Studies Initiative Advancement Award, the 2021 and 2023 Mamie L. Markham Endowment Award, the 2022 McNeil Award, the 2023 Next Swell award, and the 2024 Women Diver's Hall of Fame Graduate Conservation Award. She also received Honorable Mentions for the National Science Foundation's Graduate Research Fellowship award in 2022 and 2024.
Research
Jess’s research aims to understand fisheries as part of a larger cultural picture in the Pacific Northwest and contribute to critical outreach and engagement with the broader public. She is broadly interested in the movement and foraging ecology of top predators. Combined with a variety of anthropogenic stressors, fisheries in this region have experienced significant drops in stock, followed by ecosystem effects and repercussions on local economies. Despite their often significant roles in local ecosystems though, large sharks have been conspicuously absent from modeling and management efforts in the region. Using bio-logging, genetics, stable isotopes, and stomach content analysis, Jess’s research provides critical insights into the trophic ecology of an abundant apex predator in these marine ecosystems, the Broadnose Sevengill Shark (Notorynchus cepedianus). Her project is helping determine how predators maintain productive marine ecosystems in the Pacific Northwest from a quantitative and cultural lens while informing management of critical fisheries through top-down interactions.
Fun Fact
Jess loves photography, diving, yoga, hiking, and all forms of dogspotting. She is also an adventurous eater...just ask her sometime!

Undergraduate Students
Deven Guerrero (they/them)
Bio
Originally from Central California, Deven moved to Oregon to join the Big Fish Lab after starting off as Research Experience for Undergraduates (REU) intern. Growing up in a coastal state and visiting every science museum in driving distance, Deven developed a deep passion for science and the ocean.

Natalie Donato (she/her)
Bio
Natalie is a fourth-year Honors undergraduate student studying marine biology at Oregon State University. She grew up in Folsom, California and loves it here in Oregon but misses the sunshine back home. She has had a lifelong passion for marine science, which led her to take an URSA (Undergraduate Research, Scholarship, and the Arts) position with Big Fish Lab during her first year at OSU. That experience has sparked her interest in the sensory systems of elasmobranchs and how they interpret and respond to changes in their environment, leading to her Honors Thesis work on shark electroreceptor pore distributions. Natalie also has a dual career as an artist and dedicates time working with the lab to create hyper-realistic artwork of the species studied in the lab as well as figures, diagrams, and more for science communication. When she’s not in class, the art studio, or the lab, Natalie likes to draw outside, practice martial arts, do wildlife photography, ski, and scuba dive.
Research
The first project Natalie joined investigated how big skates and longnose skates responded to geomagnetic fields (Earth’s magnetic field) and electromagnetic fields to better understand how electromagnetic fields from cables in offshore renewable energy installations may affect their behaviors and movements. Inspired by topics from her first experience, Natalie is currently working on her Honors College Thesis developing a non-destructive method to map shark electroreceptor pores with 3D photogrammetry (photograph-based 3D modeling). After refining the method, she will collect photographs and generate 3D models of a variety of elasmobranch species to map their electroreceptor pores, since each species of shark has a unique distribution of electroreceptor pores influenced by aspects such as habitat, foraging strategies and evolutionary lineage. Comparing the electroreceptor pore distributions to those various aspects of the shark species can help explain why variations exist and can help better understand how sharks use electroreception and how human impacts may affect the capabilities of this unique sensory system.
Fun fact
Natalie has a second degree black belt in taekwondo.
