Research Experience

Graduate Student Researcher | NSF Graduate Research Fellow (2019 -2025)

Climate Carbon and Fire Dynamics Lab University of California, Irvine 

Principal Advisor: Dr. James T. Randerson (2021 - Present)

• Analyzed the influence of fires on successional trajectories after fire and changes in productivity using Landsat land cover and OCO-2 solar-induced fluorescence (SIF) in the Arctic-Boreal Vulnerability Experiment (ABoVE) study domain.

• Combined field measurements from the Anaktuvuk River fire with remote sensing to understand the mechanisms that lead to decadal enhancements of photosynthesis.

• Using SIF and surface reflectance to understand global photosynthesis anomalies and connections to atmospheric CO2

Student Researcher (2018 - 2019)

Ecoclimate Lab, University of Washington 

Advisor: Dr. Abigail Swann

• Analyzed climate simulation output to understand how changes in land surface properties can lead to cloud feedbacks that affect regional climate.
  
  

Undergraduate Student Assistant (2018-2019)

Dept. of Atmospheric Sciences, University of Washington, 

Supervisor: Dr. John M. Wallace

• Analyzed climate data and created figures for the “The Atmospheric General Circulation” textbook.
