I am an atmospheric scientist, expert in new particle formation from field observations and chamber measurements. I received my Masters degree in atmospheric chemistry in Beirut, Lebanon in 2014 and my PhD in atmospheric physics in Helsinki, Finland in 2019. I later moved to Switzerland for a postdoc position at EPFL, Sion, Switzerland in 2021. I am currently working as a scientist in the Environmental Molecular Science group within LAC at PSI. 

Scientifically, my focus has been on how humans influence aerosol particles, which in turn result in poor air quality and climate change. I have analyzed and published big data collected (+25 years) from multiple places around the world, including but not limited to, forests (Hyytiälä, Finland), remote locations (Central Arctic Ocean, Marambio in Antarctica and Mt. Everest in Nepal), Megacities (Beijing, China and New Delhi, India), as well as rural and urban locations in Lebanon, Hungary, Spain, Italy, Cyprus, Saudi Arabia, Jordan and so on. At the same time, I have been a visiting researcher at the European nuclear research center (CERN) in Geneva, where I designed and performed experiments simulating our atmosphere in a gigantic chamber to understand the role of anthropogenic influence on cloud formation in multiple environments. Via performing the abovementioned research, I collaborated with scientists and researchers from around the world from multiple large consortia in the atmospheric aerosol field. Right after my PhD, I joined the Aerosol and Haze laboratory in Beijing, China where I helped establish the research center and measurement station while supervising local master’s and PhD students in Beijing. 

In 2020, I joined the Environment Academy in Beirut, Lebanon as a volunteering scientific mentor. The Environment Academy is an NGO, founded by the Nature Conservation Center in Beirut, emerged to empower communities in Lebanon most affected by environmental breakdown. My role has been to bring my scientific knowledge into play with the local communities in villages to improve their air quality via forestation.
