- Utilize a aerosol modeling framework coupling the particle-resolved model PartMC to the Weather Research and Forecasting (WRF) model configured for large-eddy simulations (LES)- Quantify the importance of the particle-resolved treatment and high spatial resolution on estimating CCN activity by comparing CCN estimates against simulation results using the modal MAM3 model and coarser spatial resolutions

Research Triangle Park, Nc

- Designed, developed, and implemented an open-source Python library sensortoolkit for analyzing air sensor data against collocated regulatory-grade measurements. The library’s class-based architecture and method- ology for ingesting sensor data from a variety of formats allow broad utilization across sensor models and pollutants. Statistical analysis modules were included for calculating U.S. EPA’s performance targets and metrics for air quality sensors, and testing reports are generated for summarizing sensor performance- Contributed to the development of U.S. EPA performance targets, metrics, and protocols for PM2.5 and O3 air sensor evaluations, designed technical reporting templates for indicating air sensor evaluation against performance targets and metrics- Developed modular computational tools for assisting U.S. EPA colleagues with ongoing research projects, including large-volume data acquisition via various air monitoring platform APIs and NowCast AQI esti- mation for constraining correction equation model error for use by air sensors displayed on the Fire and Smoke Map developed by AirNow & the U.S. Forest Service- Conducted a sensitivity analysis of PurpleAir sensor data collected during wildfire conditions to deter- mine the impact of low hourly time series data completeness on PM2.5 concentration estimation to inform inclusion of PurpleAir devices on the Fire and Smoke Map- Coordinated and hosted a monthly webinar series showcasing current air sensor research from members of the research community

Davidson, Nc

- Constructed a computational model for magnetar stellar structure with strong magnetic fields by implementing magnetohydrodynamic simulation via the PLUTO Code for astrophysical gas dynamics.- Quantified structural deformation due to magnetic field strength via measurement of stellar ellipticity.- Determined estimates for continuous gravitational wave strain resulting from stellar deformation assuming asymmetric rotation, found simulation results to be in accordance with published wave strain estimates for highly-magnetic pulsar sources.- Defended results of a 71 page research thesis in a half-hour oral presentation and examination.
