Abid Omar

Founder, Pakistan Air Quality Initiative (پاکی)

Abid Omar has a social mission: how can I help improve the environment of Pakistan? He sees the air pollution emergency in Pakistan as a silver lining — an opportunity to drive environmental awareness and change that will clean up Pakistan for good. A key indicator of environmental issues is pollution that affects our daily lives, specifically air pollution. He found but there is no data for this, so he founded the Pakistan Air Quality Initiative as a community-driven initiative to monitor air quality in across major urban areas of Pakistan and to provide awareness for air quality and air pollution issues, and therefore provide impetus for change. His day job is in the technical textiles and filtration industries.

Alan Rossner

Professor and Associate Director of the Institute for a Sustainable Environment, Clarkson University

ALAN ROSSNER, PHD Dr. Rossner is Director of Environmental Health Science and Environmental Science & Policy undergraduate programs at Clarkson University. He is also Associate Director of Clarkson’s Institute for a Sustainable Environment. He received his Masters of Science degree in Environmental Health from the University of Washington, and PhD in Occupational Health from McGill University in Montreal, Quebec, Canada. His teaching and research interests are in human exposure to hazardous chemicals and agents. While at Clarkson, Dr. Rossner has conducted research in the areas of exposure assessment and environmental health science. A continuing challenge in environmental and occupational health is that of accurately estimating an individual’s long-term exposure to the multitude of airborne contaminants found in our work and community environments. These challenges are further magnified by the constant influx of new chemicals and new processes into our living and working environments. Research into improved exposure assessment strategies and air sampling methodologies that better characterize individuals’ exposures are necessary to further our understanding of the health effects related to airborne contaminants. To that end, Dr. Rossner has tried to direct his research in areas that minimize human exposure to contaminants, improve working conditions, improve living conditions and minimize risk of disease. His current research projects encompass three areas: 1) The development of air sampling methodologies, 2) Exposure assessment strategies for occupational and environmental air sampling, and 3) Indoor/outdoor air contaminant monitoring.

Benjamin Barratt

Deputy Director, Environmental Research Group, Imperial College London

Dr Ben Barratt is a Reader in Environmental Exposures & Public Health and Deputy Director of the Environmental Research Group.He is also head of theExposure Science Team [https://www.imperial.ac.uk/school-public-health/environmental-research-group/research/exposure-science/], currently comprising five research associates, two research assistants and up to six PhD students. The overarching aim of his team’s work is to better characterise individual and population-level exposure to environmental stress, how this relates to the health of susceptible population subgroups, and methods of public health improvement. Much of the focus of the team's work is on global air quality, primarily in China and Sub-Saharan Africa. The early part of his career focused on the establishment of co-ordinated air quality monitoring networks, including the London Air Quality Network, which became the largest urban network in Europe. He has since utilised this foundation in measurement techniques and data handling to develop analysis methods to characterise sources, trends and behaviour in urban air pollution. He specialised in the evaluation of technological or policy driven initiatives to improve air quality, including the London Congestion Charging Scheme and Low Emission Zone, the outputs of which have been used as evidence for future national and international schemes. The aim of more recent research is to improve the resolution of environmental exposure assessments for panel, cohort and large-scale population studies. This is linked to the development of tools to allow the public to make informed choices to reduce their own exposure to indoor and outdoor air pollution. His research is often in collaboration with international multidisciplinary teams ranging from toxicology and population health through to behavioural science and policy development.

My name is Pamela Ayala, graduated from the Environmental Chemistry career at the University of Chile, I am 28 years old and I have lived all my childhood in Los Andes, a small city in Chile, together with my family, my parents and my two sisters. minors, who have given me the best values and supported my whole life. I like to do outdoor activities and contact with nature, generating interest in science due to the desire to know why certain phenomena arise in nature, but then it increased when seeing that many women were interested in this area and that they were capable of doing great things for science, which was not only a man's world, and I wanted to be part of it. I believe that by bringing science and knowledge closer to all people we can generate a conscious society and reduce the effects of pollution. Currently, my work is focused on the study of atmospheric pollution by ozone, through low-cost electrochemical sensors, thanks to the help of Airfluz SPA.

Yisi Liu

Postdoctoral Researcher, University of Southern California

Yisi Liu is currently a Postdoctoral researcher at the Department of Population and Public Health Sciences, University of Southern California. She received her PhD degree in environmental and occupational health from University of Washington and her Bachelor of Medicine degree in preventive medicine from Wuhan University. Yisi has general interests in assessing the health impacts of urban environment exposures, with the goal of achieving precision environmental health and facilitating healthy promoting cities. Her recent research leverage wearable and portable sensors to characterize personal exposure to environmental risks considering time-activity and human mobility. Yisi aims to reduce exposure misclassification in environmental epidemiological studies and to understand environmental injustice and health disparities for different sub-populations.

Zhi Ning

Associate Professor, The Hong Kong University of Science and Technology

Dr. Zhi Ning’s research interests cover the innovation and development of environmental monitoring technologies with a focus on low-cost sensor algorithm and its application on air quality research. Dr. Ning has active participation in the low-cost sensor related work initiated by USEPA, WHO and WMO, and has led his team to develop the air sensing technologies for use in the first marathon route sensor network, large scale urban mobile sensor network with wide recognition locally and globally. Besides the technology development, Dr. Ning’s research also aims to understand the physical and chemical process of air pollution in complex urban built environment and their impact on the air quality and public health.
