Research Affiliates

SPHERE combined research in air and water quality, public health, energy, building behavior, social sciences, and sensors and data science to benefit the home environment. This was our group as of 2019. Many of these folks are still working together on mid-size projects.

Ander Wilson

Assistant Professor, Statistics
Colorado State University

Ander develops statistical methods and data science tools to better understand how environmental factors affect human health. His methods are designed to tease out the health effect of environmental exposures (primarily air pollution), including multipollutant mixtures and time-varying exposures.

Ashlynn Stillwell

Associate Professor, Civil & Environmental Engineering – web page
University of Illinois at Urbana-Champaign

Ashlynn studies residential water and energy consumption, and is working to create sustainable systems by understanding end uses.

Chuck Henry

Professor of Chemistry – web page
Colorado State University

Chuck develops low-cost methods for the analysis of environmental pollutants. His current laboratory development includes paper-based analytical devices and classical microfluidic devices with a variety of detection motifs, for the analysis of heavy metals and particulate matter in aerosol and water samples.

Dan Giammar

Walter E. Browne Professor of Environmental Engineering – web page
Washington University in St. Louis

Dan’s research focuses on chemical reactions that affect the fate and transport of heavy metals, radionuclides, and other inorganic constituents in natural and engineered aquatic systems. He is interested in chemical aspects of water treatment and water quality, especially reactions at solid-water interfaces and the water quality of distribution systems. 

Delphine Farmer

Associate Professor, Chemistry – web page
Colorado State University

Delphine’s group studies how human activity perturbs atmospheric chemistry, and thus air quality, forest ecology and climate change. Her group uses mass spectrometry measurements in both laboratory and field settings to study complex chemistry in both the gas and aerosol phases, across environments ranging from forests to cities to the inside of a house.

Fangqiong Ling

Assistant Professor, Energy, Environmental and Chemical Engineering
Washington University in St. Louis

Fangqiong leads a computational and experimental lab to study bacterial colonization and transmission at the boundary of built and natural environments. She explores microbiomes as environmental sensors and public health sentinels. 

Jason Quinn

Associate Professor, Mechanical Engineering
Colorado State University

Jason works on sustainability assessment, environmental impact through life cycle assessment, and economic viability through techno-economic assessment. He is interested in integrating data to validate models that can then be leveraged for sustainability assessment and used to identify targeted investments. Economics can be quantified at micro (homeowner) and macro (societal) levels.

John Volckens

Professor, Mechanical Engineering – web page
Colorado State University

John’s research connects engineering, exposure science, and public health through instrument development, exposure data science, and panel studies with human volunteers. Recent work has focused on citizen-science applications to promote environmental and public health and energy transitions in the developing world.

Paul Francisco

Director, Indoor Climate Research and Training – web page
University of Illinois at Urbana-Champaign
Researcher, Energy Institute; Colorado State University

Paul’s research focus is the interplay between energy efficiency and indoor air quality, considering the house as a system, primarily in low-income housing. He has chaired ASHRAE’s Residential Ventilation Standard (62.2),  Environmental Health, and Residential Buildings Committees.  He directs a weatherization training center, where he teaches Healthy Homes principles to practitioners.

Rich Sowers

Professor, Industrial, Enterprise & Systems Engineering and Mathematics
University of Illinois at Urbana-Champaign

Rich is interested in data and control of smart environments and in developing meaningful models of how external signals can affect the internal health of a home. Analytics, artificial intelligence, and user adoption come into play in ensuring that smart environments have impact.

Ryan Scott

Assistant Professor, Political Science
Colorado State University

Ryan’s interest is managing risks associated with oil and gas development, energy development, and air quality. His research focuses on local and state policy making. He is especially interested in participatory processes and measuring outcomes and outputs resulting from involving citizens and nongovernmental actors in public policy decision making and implementation.

Steve Simske

Professor, Systems Engineering
Colorado State University

Steve is the author of the book, Meta-Analytics, as well as 200 US patents. Until 2018, he was a Hewlett-Packard Fellow and a Research Director in HP Labs, leading HP’s R&D in algorithms, multi-media, labels, brand protection, security and secure printing, imaging, 3D printing, analytics and life sciences

Sheryl Magzamen

Associate Professor, Environmental and Radiological Health
Colorado State University

Sheryl’s primary research focus is understanding the relative contribution of social factors and environmental exposures on childhood chronic disease. She has worked extensively in elementary school settings on asthma, lead exposure, social culture and indoor environmental quality.

Tami Bond

Walter Scott, Jr. Presidential Chair in Energy, Environment and Health
Colorado State University

Tami’s scientific background is in combustion, air quality, and climate effects of air pollution. Her research has delved into systems as small as a particle’s skin and as large as a national transportation system; ultimately, her interest is in how human decisions affect local and global environments, and how those environments in turn affect their residents. 

Will Yeoh

Assistant Professor, Computer Science and Engineering – web page
Washington University in St. Louis

Will researches artificial intelligence with an emphasis on developing optimization algorithms for agent-based systems. His primary expertise is in distributed constraint optimization, and his goal is to develop and deploy algorithms in multi-agent systems including smart grid and smart home applications as well as cloud and edge computing applications.
