Dr. Judy Che-Castaldo is an ecologist working to apply theories and tools from population biology to address conservation issues. Her broad research interests have led to a varied background that includes researching both animals and plants, from field experiments to analysis of large datasets. Judy was a postdoctoral fellow at SESYNC, where her research focused on improving recovery planning for species listed under the Endangered Species Act. Prior to her time at SESYNC, Judy conducted a wide range of biological research, from animal behavior (studying mate-choice and fitness) to phytoremediation and the ecology of non-native species. Judy is currently a Research Scientist at Lincoln Park Zoo, where she combines her previous experience in population modeling and large-scale comparative analysis and applies them to species conservation and management. Her research projects include looking for patterns in vulnerability across zoo populations and analyzing data on breeding and transfer recommendations to improve the management of zoo-based and wild populations. She is also developing the COMPADRE and COMADRE Matrix Model Database, a global repository for plant and animal demographic data.
