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.




William Apondo is an Air Quality Data Analyst for the Cities program. He supports the Emission Inventory team with collecting, processing, and analyzing indicator data for the emission inventory being developed for the cities, including the efficiency of data collection and analysis processes, and routine data QA/QC analysis to establish the scientific robustness of the collected data.



I am a final-year PhD student with the Atmospheric Sciences Research group at the North-West University (NWU) in South Africa. My PhD research uses eddy-covariance techniques to measure the first-ever fluxes of SO2 and NO2 with specific focus on the dry deposition of these acidifying species in a semi-arid African savanna. I have a background in ecology and interest in terrestrial-atmosphere interactions, climate change and biogeochemistry.



Diana Halim is from Sarawak, a cultural state on Borneo Island of Malaysia. She received her Bachelor’s Degree in Science in Microbiology in 2012. Diana then went on to earn a Master’s of Environmental Management (majoring in Atmospheric Science) in 2015 and a Ph.D. in Environment and Development from Universiti Kebangsaan Malaysia (UKM), MALAYSIA in 2021, where her Ph.D.



Key challenges for tropospheric chemistry in the Southern Hemisphere 


Nasim Hossein Hamzeh received her PhD in Meteorology at the Atmospheric Science and Research Center in Iran and her M.Sc degree in Astronomy at the University of Isfahan. Currently, she serves as a Central Asia regional representative in the Young Earth System Scientist (Yess) Community. Past projects have researched the origin of foreign dust in Iran and the identification and source characterization of mineral dust on the north shore of the Persian Gulf.
