In 2014, John joined the Association of Zoos and Aquariums (AZA) Population Management Center (PMC) in a newly created position that helps the center provide additional services to population management programs around the country.

John’s previous research experience focused on avian ecology and questions concerning habitat selection behaviors of grasshopper sparrows. His work was used to improve conservation management of declining grassland bird species in Central Illinois. He later went on to work on various avian research projects in Panama; Australia; and, most recently, back in Illinois with the Illinois Natural History Survey, where he studied haemoparasites in avian populations.

John started his career with animals as a bird keeper at the Jacksonville Zoo in Florida. He developed a passion for animals and zoo work through his keeper days and has returned to the zoo field. His unique experience as an animal keeper, teacher, and field researcher make him well suited to working with the PMC to manage and conserve zoo species for the AZA.
