Early Career Committee


Co-Chair I

Jenniffer Pedraza
SEI York, UK

Jenniffer recently joined SEI York from the Ministry of Environment and Sustainable Development in Colombia, where she was engaged in work on formulating and implementing the Air Quality and Short-Lived Climate Pollutants national strategies. This involved working with the Climate and Clean Air Coalition.
She has a PhD in Chemical Engineering from the Universidad Nacional de Colombia, and her specialism was carbon capture, storage, and utilization in industry. She has further research experience in energy transition and decarbonization, emissions control, life cycle analysis and carbon footprinting.
At SEI York, she is developing a regional SLCP emissions inventory for the Latin American and Caribbean (LAC) region and health impact assessments as part of the FOCI project. She is also working to support National Planning Actions to reduce SLCP emissions in LAC including methane mitigation roadmaps.
Jenniffer is a member of the Latin America Early Career Earth System Scientist Network which supports the work of Earth system scientists in the region. Read more about LAECESS in this 2022 issue of Nature: Climate and Atmospheric Science.

Co-Chair II

Behrooz Roozitalab
US NSF National Center for Atmospheric Research

Behrooz is a post-doctoral fellow at the US NSF National Center for Atmospheric Research. His research primarily focuses on investigating the sources and global distribution of short-lived halocarbons. Behrooz has completed his BS and Master’s studies in Iran and earned his PhD from the University of Iowa. Behrooz is the co-chair of the 2024 IGAC short course and is excited to meet his peers in Kuala Lumpur. 


Hasan Nawaz
University of Wollongong, Australia

Hasan Nawaz is a PhD student in the Centre for Atmospheric Chemistry, School of Earth, Atmospheric, and Life Sciences, University of Wollongong, Australia. He is interested in studying variability and trends in atmospheric aerosols and greenhouse gases using remote sensing applications.
His primary work during his PhD is on remote sensing of methane and its major sources in Australia.

Priyanka Srivastava
National Institute of Environmental Studies (NIES), Japan

Priyanka Srivastava is a post-doctoral researcher (since Feb 2023) at the National Institute of Environmental Studies (NIES), Japan. Her research interest involves characterizing air quality mainly concerning carbon-based aerosols and trace gases (CO, CO2 and CH4).
The prime focus of her current research is developing a high-resolution urban emissions inventory for GHGs and SLCFs utilising geostationary satellites and in situ observations including cargo-ship.
Prior to this, she did her Bachelor’s and Master’s in Physics. She received her PhD (Feb 2021) studying Carbonaceous Aerosols over the Central Himalayas under the ISRO-ARFI project from Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, India. Her thesis specialized in source apportionment studies of online and offline measurements of aerosols and radiative transfer and regional chemistry modeling designed for the complex terrain of the Himalayan region.

Nor Diana Abdul Halim
Sarawak Development Institute (SDI), Malaysia

Diana Halim is from Sarawak, a cultural city in the Borneo Island of Malaysia. She received a Bachelor’s Degree of Science in Microbiology from Universiti Kebangsaan Malaysia. Diana then went on to earn a Master’s of Environmental Management (majoring in Atmospheric Science) and a Ph.D in Environment and Development (a study of long-term urban air pollution from land use changes effects in the mega-urban region) from Universiti Kebangsaan Malaysia in Bangi, Selangor, Malaysia. She has completed her two-year Postdoctoral Programme at the Institute of Climate Change and Faculty of Science and Technology, Universiti Kebangsaan Malaysia. Currently, Diana is a Senior Research Officer at Sarawak Development Institute, Kuching, Sarawak, Malaysia. Her research focuses on analyzing the impact of urban forms effects from development on air quality by using GIS and studying the atmosphere-land interaction, particularly on regional air pollutants and greenhouse gas emissions from land use activities, towards reducing the climate change impacts and achieving sustainable development.

Nurzawani Md Sofwan
Universiti Teknologi MARA, Sarawak, Malaysia

Nurzawani Md Sofwan is from Johor, Peninsular Malaysia. She earned a Bachelor’s Degree in Environmental Technology and a Master’s Degree in Environmental Science. Her doctoral degree, a PhD in Environmental Science, was obtained from Universiti Kebangsaan Malaysia (UKM). Her doctoral research centers on two main areas: the development of a traffic emission inventory and air pollution epidemiology. Through her work, she seeks to contribute to a better understanding of how traffic-related emissions impact air quality and, subsequently, influence public health. Presently, she serves as a Senior Lecturer in Environmental Health, at the Faculty of Health Sciences at Universiti Teknologi MARA (UiTM) Sarawak. Her current research extends to understanding the presence and impact of microplastics in water sources, as well as investigating the environmental and health implications of black carbon pollution.

Sachin Kumar Mishra
Indian Institute of Science Education and Research Mohali

I am Sachin Kumar Mishra. I am a Ph.D. student in the Department of Earth and Environmental Sciences at the Indian Institute of Science Education and Research Mohali. I have completed a Master’s in Chemistry from Sri Sathya Sai Institute of Higher Learning, Prasanthinilayam, Andhra Pradesh. My research focuses on the Emission and Chemistry of volatile organic compounds (VOCs). I utilize various analytical techniques, such as PTR-TOF-MS and PTR-QMS, for accurate measurements of VOCs. Areas of particular interest include investigating the sources and sinks of reactive volatile organic compounds, delving into multiphase chemistry, and exploring the complexities of ozone chemistry.

Sylvain Gnamien
University Felix Houphouet-Boigny (Abidjan, Cote d’Ivoire)

He works on air quality, on the development of inventories of greenhouse gas emissions and other air pollutants and on the evaluation of policies to mitigate air pollutant emissions. He holds a Ph.D. in physics from the University Félix Houphouet-Boigny in Côte d’Ivoire.
To date, he has conducted studies on the monitoring of the chemical composition of the atmosphere, on the analysis of the oxidative potential of atmospheric aerosols, on the development of regional and city-scale emission inventories, on fine-scale modeling of air quality, which has resulted in several research articles in scientific journals, providing valuable insights into air quality and emission sources in West Africa. Her work highlights the importance of addressing the significant public health consequences of air pollution in the African context. As part of his research, he has participated in international conferences and events, strengthening his knowledge and network in the fields of air quality assessment and improvement in West Africa.
Sylvain Gnamien is a researcher at the Laboratory of Materials, Environmental and Solar Energy Sciences (LASMES) of the University Felix Houphouet-Boigny, Abidjan (Côte d’Ivoire) and collaborates on projects with researchers from various laboratories around the world, such as the Laboratoire d’Aerologie de Toulouse (France).
