Delton Chen

Delton Chen an Australian civil engineer whose career is focused on the development of models of groundwater flow, surface water interactions, mining projects, and environmental impacts. Delton has used his skills to analyze and model the feasibility of a 4.2-km-deep ‘hot rock' geothermal power plant that was proposed for outback Australia, near the town of Innamincka.


Delton's current passion is the development of an award-winning international policy, called ‘Global 4C Risk Mitigation’, which aims to strongly mitigate climate change. In 2013, Delton co-founded www.global4c.org with the Center for Regenerative Community Solutions (USA) and EconoVision (Netherlands). Global 4C is a monetary policy for climate finance and global risk management, and is based on a new market hypothesis that combines classic economics with the physics of currency systems. Global 4C offers a roadmap for managing the economy with a parallel currency that can price systemic risks, protect ecosystems, and create opportunities for social cohesion.

Delton earned his Ph.D. from The University of Queensland for researching the geo-hydrology of Heron Island - a coral cay in the Great Barrier Reef. He also received his Bachelor's of Engineering degree in Civil and Structural Engineering from The University of Queensland.

Troy Hottle

Troy is an ORISE Postdoctoral Fellow at the U.S. Environmental Protection Agency, focusing on energy modeling and the use of life cycle assessment. He graduated with a PhD from the Ira A. Fulton Schools of Engineering at Arizona State University. His dissertation looked at optimizing the end of life treatment of biopolymer wastes from an environmental and economic perspective. Using life cycle assessment, material flow analysis, and dynamic modeling, Troy quantified the environmental end of life profile for biopolymers and added to the fundamental understanding of compostable biopolymers in real disposal systems. Additionally, he evaluated the possibility of enhancing degradation rates of biopolymers in industrial composting systems.

Prior to his PhD, Troy worked as the project manager and technical expert at Steel City Biofuels which quickly became a part of Penn State through Extension Services. As a Program Associate for Penn State he wrote grants focused on the development and implementation of biofuel infrastructure in the region. Troy next took a job at GTECH Strategies where he served as the Reclamation Projects Manager. While at GTECH he led several projects of note including researching the possible application of man-made soils using residual industrial products, neighborhood-based environmental assessments for vacant land, and developing standard procedures for the evaluation of potential project sites for the organization. Additionally, Troy is Permaculture Design Certified and was a Penn State Master Gardener. While in Pittsburgh he lectured at Phipps Conservatory on composting and garden design.

Troy moved to Tempe, Arizona in 2012 to pursue his PhD in Sustainable Engineering. Troy received his bachelor's degree from Hiram College, and through his studies there he had the opportunity to study in more than 10 different countries.
