Hi,

I am Dr. Nsikanabasi Silas Umo, an atmospheric chemist and Assistant Professor in the Department of Chemistry and Biochemistry at the University of North Carolina Wilmington. I am passionate about understanding how tiny particles in the air—like dust, volcanic ash, and soot—influence clouds, water security, air quality, weather, and their impacts in the atmosphere. 

My research focuses on aerosol–cloud interactions, ice-nucleating particles, and atmospheric chemistry of aerosol particles. At Umo AeroCloud Laboratory, I study the role of aerosols in cloud formation, air quality, energy, water security, and climate change. My studies on volcanic ash, combustion aerosols, sulfur oxidation products, and soil dusts have significantly advanced both laboratory science and global climate modelling. My work combines laboratory experiments, field studies, and modelling to uncover how these particles affect precipitation, air pollution, and global climate systems.

Beyond research, I also engage in teaching and training students, developing novel aerosol instrumentation and technologies, and collaborations. I enjoy hiking, badminton, and volunteering in my community.
