IGAC has a strong focus on engaging the next generation of atmospheric scientists through its early career program.  These scientists join an international network early in their career that creates relationships that facilitate atmospheric chemistry research at an international level for years to come.

IGAC cultivates the next generation of scientists by:


Hiroshi Tanimoto is the Head of Global Atmospheric Chemistry Section at National Institute for Environmental Studies (NIES) in Tsukuba, Japan. He received his PhD in Chemistry from The University of Tokyo in 2001 and was a visiting scholar at Harvard University during 2007–2008. Dr. Tanimoto has been working in the field of atmospheric composition in Asia and Oceania regions.



Mark Lawrence is a scientific director of the cluster “Sustainable Interactions With the Atmosphere” (SIWA) at the Institute for Advanced Sustainability Studies (IASS, www.iass-potsdam.de) in Potsdam, Germany.



ICSHMO 2025 promises to be an extraordinary gathering of scientists, researchers, and professionals from around the globe, offering a platform for the exchange of innovative ideas, cutting-edge research, and groundbreaking developments. This conference is particularly pertinent today as the world faces numerous environmental challenges, including the impacts of climate change. According to the 2024 Global Risk Report, extreme weather events are identified as the most significant risks the world will confront over the next decade.


Kathryn is a principal research scientist at Australia’s national science agency, the
CSIRO. She gained a PhD in atmospheric chemical modelling from Lancaster
University in the UK, specialising in the gas to particle partitioning of organic
hydrocarbons. She has experience developing chemical models of all scales – box
models, regional and global models. She did a postdoc modelling radical formation
chemistry at the University of York, before implementing a stratospheric sulfur
scheme to the UK chemistry and aerosol (UKCA) model at Leeds University. She



Dr. Rami Alfarra is the Air Quality Lead and acting director of the Environment Center at Qatar Environment and Energy Research Institute (QEERI) at Hamad bin Khalifa University (HBKU) in Doha, Qatar. He has over two decades of international experience in atmospheric aerosols and their impact on air quality, climate change, and human health. Dr. Alfarra leads applied research close to the interface between science and policymaking focusing on air quality assessment, sources, and atmospheric processes of air pollution and their human health impacts in urbanised arid regions. 



Please mark your calendars for HEI's next Annual Conference Sunday, May 4 - Tuesday, May 6, 2025 at the Austin Marriott Downtown in Austin, Texas. The conference is always a great opportunity to hear about cutting edge research related to environmental exposure assessment and environmental health and for connecting with friends, peers, and colleagues. The 3-day event will include updates on HEI-funded research, scientific sessions, keynote speakers, poster presentations, and much more.


21th GEIA Conference -- Emissions Science for a Transitioning World

9-11 July 2025      Abidjan, Ivory Coast        Félix Houphouet Boigny University


n June 2025, the ACAM community will gather in Bali, Indonesia for its 6th biennial workshop and training school. Since the first ACAM workshop in 2013 in Kathmandu, ACAM events have been held at locations across the Asian monsoon region, including Thailand, China, Malaysia, and Bangladesh. Over this period, ACAM has promoted close coordination across satellite observations, field campaigns, and modeling to better understand and characterize the interactions between atmospheric composition and the Asian monsoon.
