Daly-Engel, Toby

Assistant Professor, Ocean Engineering and Marine Sciences

The Florida Tech Shark Conservation Lab studies the molecular ecology and evolution of sharks and other highly-migratory marine animals with the goal of helping to create effective management policies. Dr. Daly-Engel's work focuses broadly on the evolution of reproductive strategies, and how reproductive investment can impact stock structure, migration, and habitat use. 

Personal Overview

Dr. Daly-Engel’s research combines genomics with marine ecology to study the evolution of mating strategies in animals that invest heavily in reproduction, especially sharks and rays. She is interested in how reproductive behaviors, particularly from a female fitness perspective, interact with the environment to influence species, populations, and genomes. Her PhD work at the University of Hawaii explored the ecological and genetic effects of female promiscuity in sharks, a subject she expanded on using an insect model as a postdoctoral fellow at the University of Arizona. As an Assistant Professor at the University of West Florida, Dr. Daly-Engel worked with collaborators from academia and the National Marine Fisheries Service to monitor marine biodiversity and study the evolution of reproductive strategies in both shallow-coastal and deep-water sharks. She joined the faculty at FIT in Fall 2017. Her teaching experience includes an NSF GK-12 Fellowship, an NIH Postdoctoral Fellowship in Research and Teaching, and several years developing research-based undergraduate coursework at the UWF, where she was honored with the Student Government Association’s Distinguished Teaching Award in 2016. Dr. Daly-Engel has authored over 20 peer-reviewed publications, and made a number of media appearances based on her work, most recently on Discovery Channel’s Shark Week 2018 30th Anniversary special “Great White Shark Babies”.
