AbstractMy name is Yumeng Cui, a fifth-year Ph.D. candidate from the University of California, Riverside, and I anticipate my graduation in the Spring/Summer of 2023. My research projects focus on the formation of SOA particles and secondary brown carbon particles from anthropogenic and biogenic VOCs under various conditions, investigation of their chemical and optical properties, and determination of the compounds that contribute to the formation of chromophores in aerosol particles.
My first project (Cui et al., ACS Earth Space Chem., 2021) used chamber experiments to study the SOA formation from an anthropogenic (1-methylnaphthalene) and a biogenic (longifolene) VOC under different NO
x and NH
3 concentrations and relative humidity. My second project studies the SOA and brown carbon formed from single VOC vs. multi-VOCs systems by continuous-flow chamber experiments. Another ongoing collaborating project investigates the SOA formation from dimethyl sulfide in an oxidation flow reactor and the resulting particles’ chemical composition. My final proposing project will use machine learning to study the experimental data collected from my past chamber experiments. The most important data from chamber experiments include the real-time mass spectra of the particles. However, the quantity and complexity of the mass spectrum data make it challenging to manually identify the important chemical ions related to the absorbing compounds in particles. Thus, in my last project, I plan to use machine learning to explore relationships between the SOA mass spectrum data and the simultaneously measured optical data in all the chamber systems I have studied.
After graduation, I would like to continue my track in scientific research-related careers. I am looking forward to the job opportunities related to atmospheric chemistry, air pollution, and climate change.
