Jennifer DeWinterJennifer DeWinter

Atmospheric Scientist, Sonoma Technology Incorporated

Since joining STI in 2008, Jennifer has applied her technical expertise to conduct analyses on a diverse array of projects for federal, state, local, and international agencies. Her work encompasses fire science, remote sensing, large-scale transport modeling, near-road data analysis of black carbon, and chemical mass balance modeling using PM2.5 speciation data sets. She is eager to explore air pollution issues from many perspectives and employs a systems thinking approach to ensure responsible and sound scientific results. Jennifer uses a variety of analytical tools including GIS for geospatial analysis and cartography, statistical packages, and imagery tools for evaluating remote sensing data products. She also develops custom software programs and tools for innovative analysis and visualization, as well as software for major programs such as the U.S. EPA’s AirNow program and the BlueSky Framework. Jennifer also creates custom graphics to visually display air quality data and results, as she did recently for the EPA’s annual air quality status and trends reports, effectively portraying scientific, national-scale data sets so that they can be understood by the general public.

Adrian Dybwad

Founder, PurpleAir

PurpleAir was born in the fall of 2015 out of Adrian’s curiosity surrounding air quality in his Salt Lake Valley community. Today, PurpleAir’s global network has grown to thousands of sensors measuring real-time air quality made accessible to the public via their interactive map.

After discovering his passion for technology at a very young age, Adrian spent many years honing his skills in complex electronic repairs, surface mount assembly and prototyping. This expertise, combined with two decades of experience in computer programming, network engineering and software development, enabled him to create PurpleAir.

Angela EatonAngela Eaton

Director, Safecast

Angela Eaton leads Safecast’s air quality and radiation monitoring efforts in the U.S. and supports communities looking to engage in environmental monitoring throughout the Americas. Angela is currently working with the Los Angeles Public Library on their efforts to build citizen science communities at branches and seeks new ways to encourage environmental monitoring as a means to satisfy the curious and empower communities. To this she brings previous experience in sustainable systems design in urban water infrastructure and has consulted non-profits, utilities, and cities in conservation and greenhouse gas reduction. Angela has served as a SXSW Eco Advisory Board member and has participated as a Civil Society Working Group reviewer during the United Nations Habitat III process in which the current sustainable development goals were established.

Yisi LiuYisi Liu

PhD Student, University of Washington

Yisi Liu is currently a PhD student in Department of Environmental and Occupational Health Sciences in University of Washington. She gained her Bachelor of Medicine in Wuhan University, China. Yisi has general interest in health effects of air pollution. Her recent research mainly focuses on traffic-related air pollution. Since traffic is one of the major sources of air pollution in urban areas, Yisi’s studies exploit mixture of methods to understand: air pollution concentrations in different microenvironment, personal air pollution intake during traveling, determinants of transportation modes choices, short-term cardiorespiratory health effects of traffic-related air pollution, and potential strategies to control traffic-related air pollution exposure for intra-city travelers.

Peter PedersenPeter Pedersen

University of Cambridge

Peter has two masters, one in Physics (2017) and another in Sensor Technologies (2018), and is currently undertaking a PhD in Astrophysics. Through his degrees he has gained expertise in remote sensing, embedded systems, and machine learning. In his second masters, he co-founded an initiative called open-seneca, which works towards creating a global, mobile, air pollution sensor network. He has had success implementing pilot studies with the Argentine government and the UN, where this initiative has won several awards, including the University of Cambridge’s Vice-Chancellor's Research Impact and Engagement Award in 2019.
