Please introduce yourself here and tell us about your experiences with pollution related to fine particulate matter and your expertise in the area.

Hello everyone! My name is James Burbridge, lead analyst for the Clean Air XPRIZE. Prior to this prize design I worked on the Carbon Removal XPRIZE. My background is in energy journalism, covering the Chinese energy complex, Southeast Asia natural gas, Singapore and Asia-Pacific fuel oil markets, and North American carbon trading.

Having lived in Shanghai, Singapore, and Los Angeles, I am acutely aware of the hazards of air pollution and particulate matter and am eager to dive in and better understand how a prize can help fix this global problem.

Hi there! I’m Jessica Yoon, assistant product manager at XPRIZE for the Clean Air Prize Design. I’ve also been part of XPRIZE’s Future of Longevity Impact Roadmap, which looked into the possibilities of extending healthy human aging and lifespan. I’m excited to expand into another area of study that would allow people to live healthier lives, by breathing cleaner air.

This issue also hits home for me as I have many family members living in East Asia, who are affected by the severe air pollution in their cities on a daily basis. I look forward to everyone’s subject matter expertise and guidance as we delve into this prize design. Thank you!

Hello Clean Air Prize Design community! My name is Terry Mulligan and I am the product manager for the Clean Air XPRIZE. Prior to this prize design I led the Amazonia XPRIZE prize design. My background is in international development, organizational management, and management consulting.

Hi Dan, @DanBowden

Welcome to the community!
Please introduce yourself and tell us about your experience with air pollution.

Hello everyone. Way back in 1994 I successfully completed my PhD in traffic pollution (air pollution). Almost all of the problems associated with today’s air pollution were known about way back then! Despite this, decade after decade political apathy and blunders [e.g. UK’s promotion of diesel] have brought us to this huge health problem that impacts millions of people globally.

Did you know that California set a target along these lines? => By 1998, 10% of new vehicle sales would have to be zero emission [electric] vehicles. That date came and went, but it was probably the right policy [even if the technology wasn’t quite ready].

Now it looks like we might finally deliver the solutions that are required.

The simplest policy for clean air is to ban all combustion processes! Easy to say; harder to do. Even burning a “clean” fuel in air can create pollution, as high temperatures turn some of the air into nitric oxide (NO), which oxidises to NO2 (jointly referred to as NOx). This is a significant pollutant.

Could we really do without combustion? Perhaps the new XPRIZE for abundant clean energy will help to deliver on this [with clean electricity for energy, heat, transport and industrial processes]. It’s worth pointing out that fuel doesn’t have to be burnt - for example hydrogen (fuel) can be used in a fuel cell to produce electricity, with water as the only output emission.

Hi everyone. I’ve got a PhD in traffic pollution (monitoring, prediction and control of air pollution). So I feel happy and obliged to help out :slight_smile:

Hi All,

Dan here. I lead a team in who have a revolutionary form of respiratory protection and empowerment for those at risk ( We’ve even taken respiratory protection to the cat walks of New York. Always keen to collaborate.


Hi Joseph, @josephjjames

Welcome to the community Dan! @djaffe
I went through your blog and was impressed by the amazing work done by you and your team.
Probably you could answer @TerryMulligan question on existing or proposed solutions for tackling particulate pollution’s reduction or removal here.

Welcome @hopkepk! Thank you so much for joining our community. We’re grateful to have your expertise to advise us on a variety of research questions through this platform.

Welcome to our community Dr. Philip, @hopkepk!
We are honored to have you on our community.

Please advise us on:
• Existing or proposed solutions for tackling particulate pollution’s reduction or removal.
• Best articles or research papers you have read in the last 12 months on air pollution related to fine dust particulate matter. Are there any landmark publications we should know about?


To introduce myself, I am providing a brief biographical paragraph on my involvement in clean air. Dr. Philip K. Hopke is the Bayard D. Clarkson Distinguished Professor Emeritus at Clarkson University, and former Director of the Center for Air Resources Engineering and Science (CARES), and former Director of the Institute for a Sustainable Environment (ISE). He also holds an adjunct professorship in the Department of Public Health Sciences at the University of Rochester School of Medicine and Dentistry. Dr. Hopke is a past Chair of EPA’s Clean Air Scientific Advisory Committee (CASAC), and has served on the EPA Science Advisory Board (SAB). Professor Hopke is a Past President of the American Association for Aerosol Research (AAAR), and was a member of the more than a dozen National Research Council committees. He is a member of the NRC’s Board of Environmental Studies and Toxicology. He is a fellow of the International Aerosol Research Assembly, the American Association for the Advancement of Science and the American Association for Aerosol Research. He is an elected member of the International Statistics Institute and was the recipient of the Eastern Analytical Symposium Award in Chemometrics and the Chemometrics in Analytical Chemistry Conference Lifetime Achievement Award. He is also a recipient of the David Sinclair Award of the AAAR and co-recipient of the 2018 Fissan-Pui-TSI Award for International Collaboration presented by the International Aerosol Research Assembly. He served as a Jefferson Science Fellow at the U.S. Department of State during the 2008-09 academic year. Professor Hopke received his B.S. in Chemistry from Trinity College (Hartford) and his M.A. and Ph.D. degrees in chemistry from Princeton University. After a post-doctoral appointment at M.I.T. and four years as an assistant professor at the State University College at Fredonia, NY, Dr. Hopke joined the University of Illinois at Urbana-Champaign, rising to the rank of professor of environmental chemistry, and subsequently came to Clarkson in 1989 as the first Robert A. Plane Professor with a principal appointment in the Department of Chemistry. He moved his principal appointment to the Department of Chemical and Biomolecular Engineering in 2000. In 2002, he became the Clarkson Professor and Director of CARES. On July 1, 2010, he became Director of ISE that houses Clarkson’s undergraduate and graduate environmental science degree programs as well as managing its sustainability initiatives. In May 2016 he moved to emeritus status.

Welcome to the community Chris! @ckellogg
We are trying to analyse effectiveness of various solutions to reduce fine particulate pollution here. Please join the discussion.

I’m Tony Miller, Ph.D., CEO of Entanglement Technologies, a company developing high performance analyzers to address pollution issues. We’ve been helping address chemical pollution primarily (including impacts of wildfires, hurricanes, industrial activity, and accidents). I’m thrilled to see an XPrize heading to the heart of the issue that will have such a dramatic impact on global health and wellness. We spend our days thinking about pollution and solutions and would love to help in any way that we can.

Hi @ET_Tony , welcome to the community. Looking forward to hearing more of your thoughts on how we can tackle urban air pollution.

Hi, I am Ananya Roy, Senior Health Scientist at Environmental Defense Fund. I am an environmental epidemiologist and am currently working on leveraging sensor technologies to measure and map air pollution and its health impacts in cities. We have been working with academic, industry, community partners and government officials to collect detailed air pollution and health data in neighborhoods, providing pollution insights literally block by block. We use these local insights to increase awareness and bring science, health, economics and partnerships to the table in decision making, allowing local data to drive local solutions.
Thrilled to be part of this important conversation.
