Justin Ziegler serves as the Biometrics and Quantitative Analysis Manager for Aster Global Environmental Solutions. In this role, Dr. Ziegler is responsible for the quantitative review of client and project data for carbon sequestration validation and verification projects. His responsibilities include meeting the internal and external client objectives in the fields of forest inventory and sampling, growth and yield modeling, and directly in support of offset validation/verification projects. In addition, he focuses on streamlining and developing quantitative tools as part of ongoing continuous improvement efforts. This latter focus assures increasing product and service value for clients. Dr. Ziegler brings a wealth of previous experience to this role and has worked in the areas of forest carbon modeling, fire ecology, and forestry for the last 11 years. In his prior role as a Forest Systems Carbon Modeler, he developed web-based greenhouse gas (GHG) accounting software for forest and agroforest landowners. He also worked to improve existing models describing ecosystem dynamics and greenhouse gas inventories. This work relied heavily on the application of statistical methods to develop allometrics and ecosystem biometrics. Prior to joining Aster Global, Dr. Ziegler has also worked as a forest consultant and in university, public agency, and private settings working as a wildland fire ecologist, planning forester and inventory forester. In these roles, he gained valuable knowledge and experience directly related to his current role with Aster Global. Some of his most significant professional accomplishments include developing protocols for GHG accounting for the United States Environmental Protection Agency, developing software for wildland fire behavior modeling, and the authoring of numerous forest stewardship plans and silvicultural prescriptions. Dr. Ziegler has published 14 peer-reviewed academic papers on predicting wildland fire behavior prediction, ecological restoration, wildland fuels management, and carbon modeling. He has been a featured presenter at numerous professional development conferences throughout the United States on topics including forest management, estimating carbon stocks in windbreak systems, and wildland fire mitagation.
