Summary

Lauren Zamora, an associate research scientist at University of Maryland and NASA Goddard, presents a career retrospective at her alma mater, Rosenstiel School. She traces her journey from PhD work on Saharan dust and atmospheric nutrient deposition to her current focus on Arctic aerosol-cloud interactions. She discusses key papers, including Duce et al. (2008) on nitrogen deposition, and her own work on organic nitrogen and nitrous oxide modeling. She highlights the importance of fieldwork, workshops, and international collaboration. She then describes her transition to NASA, where she studies Arctic clouds and their interactions with aerosols. She covers challenges in observing the Arctic, the rapid warming of the region, and emerging topics like polar mixed-phase cloud thinning as a climate intervention. She concludes with career advice for students, emphasizing mentorship, resilience, and the value of diverse experiences.
