Following his time working in the field, Thompson worked for six years as an Environmental Specialist for the Watershed Planning Group at City of Portland’s Environmental Services. He managed ecological research and restoration projects in Portland’s watersheds, while also helping to develop watershed-specific and citywide watershed plans. Work also included watershed inventories identifying areas for green infrastructure, natural resource inventories to evaluate ecological health and restoration opportunities, stream investigations to identify salmon habitat projects and validation of GIS-based ecological health models. He participated in numerous citywide policy committees tasked with updating environmental and watershed protection policy. While in Portland, he was a volunteer and board member with the Columbia Slough Watershed Council for eight years. Thompson then moved to Wisconsin and managed small wind and solar development projects in Wisconsin. He managed the project from an initial concept to a fully, commissioned renewable energy system, and was involved in all aspects of the project process from site evaluation and resource assessment to sales and permitting.

    Brian Tippetts, B.S.
    Brian TippettsDirector, Science Waste Division
    Wisconsin


    As the Director of AES’ Solid Waste Division, Tippetts assists landfill owners in developing or improving cost-effective sustainable-land management which results in lower long-term care costs, enhanced neighbor relations, greater use of waste resources, and increased potential for future landfill expansion. Throughout the process, Brian focuses on the use of natural ecological systems/approaches and waste management strategies for the landfill and the surrounding lands. He has had considerable success striking a balance between the environment, and the waste that impacts it, all over the U.S. and the world for the past 30 years. Brian currently serves on the International Board for the Solid Waste Association of North America (SWANA) and also serves on the Editorial Advisory Board of MSW Management.

    Fugui Wang Ph.D.
    Fugui WangRemote Sensing Analyst-Ecological Modeler
    Brodhead, Wisconsin


    Dr. Fugui Wang joined AES in 2012 as a Remote Sensing Analyst and Ecological Modeler. Wang brings extensive technical knowledge and research credentials to the company, especially in regards to mapping natural resources and their responses to natural disasters and forest pests. His work at AES encompasses remote sensing analysis, GIS assessment and modeling impacts on ecosystems using a variety of process-based and hybrid ecosystem models. Wang’s areas of expertise include pre-processing (radiometric and geometric correction) and post-classification of Landsat and MODIS products with various methods (supervised, image segmentation and knowledge classification approaches) as well as manipulating raster and vector data. He is well-versed in ecosystem models including PnET-II/-CN, Century, Biome-BCG, FORECAST and LANDIS-II. His projects have included using Landsat and MODIS imagery to determine hurricane damage and long-term dynamics and recovery to forests; applying Landsat imagery to assess water quality; acquiring and interpreting airborne videos to investigate trees damaged by forest pests; modeling impacts of climate change and management practices on ecosystem C/N states and fluxes; and interpolating forest ecosystem carbon stock and sequestration potential at a watershed scale.

    Steve R. Zimmerman, M.S.
    Steve ZimmermanStaff Ecologist
    West Dundee, Illinois


    Steve has seven years of professional experience in aquatic system biology, hydrology, and restoration including fisheries management, stream assessment, stream and shoreline restoration, watershed planning, wetland delineation, erosion control, hydrology monitoring, water chemistry monitoring, and vegetation monitoring. As a consulting ecologist and project manager, Zimmerman is active in all phases of wetland, stream, or pond management. He is proficient in stream health evaluations and has hands on experience with fish community sampling and habitat analysis/restoration using a variety of sampling techniques such as Karr’s, Simon’s and the EPA’s version of the Index of Biotic Integrity (IBI), Macroinvertebrate Biotic Index (MBI), Qualitative Habitat Evaluation Index (QHEI), and Rosgen’s stream restoration designs. He has also researched and developed lake, stream and watershed studies, including watershed management plans, feasibility studies and stream inventory/restoration studies.
