Dr. Kirsten Fossum graduated from Colorado College, Colorado Springs, CO, USA, in 2014 with a B.A in Environmental Physics. She received a Ph.D. in Atmospheric Physics in 2018/19 for work on Marine aerosol effects on cloud condensation nuclei and ice nuclei from the National University of Ireland, Galway, later renamed University of Galway.

Her present work, on projects within the Centre for Climate and Air Pollution Studies (C-CAPS), is focused on aerosol physico-chemistry, formation, sources, climate and health impacts. She has led many first-author scientific papers, co-authored many more, authored multiple progress reports for funders and project final reports, been involved or led several field-projects, and given presentations at over 10 international conferences, several national symposiums, and multiple outreach and communications talks to the public and private sectors.

Her research focusses on applied atmospheric physics, namely investigating aerosol-cloud dynamics, aerosol physico-chemical properties, impacts of aerosol on climate and air quality. Her specialty is the application of advanced scientific instrumentation for measuring aerosol physical and chemical properties, including the use of aerosol mass spectrometry techniques. Kirsten's work is driven by a commitment to serve the public-interest and protect our natural resources for future generations.

She is a member of the International Committee on Nucleation and Atmospheric Aerosols, The Aerosol Society, and the international Surface Ocean Lower Atmosphere (SOLAS) Project.
