Biography

I am a broadly trained physical geographer and quantitative ecologist. My research aims to understand how the function and structure of the terrestrial ecosystem respond to global environmental changes at regional to global scales. I take a data-model synthesis approach that integrates satellite and airborne remote sensing, monitoring networks, and forest inventory with Bayesian hierarchical models to answer my research questions. Currently, I am working as a postdoc with Dr. Jim Clark and Dr. Jennifer Swenson. To date, my postdoc project has

  • Provided the first reproduction-related evidence on tree physiological senescence
  • Quantified seed production in tree species across all vegetated continents and provided a previously unmeasured dimension of tree fitness
  • Revealed the soil fertility effects on tree reproduction and pointed to the urgent need to improve forest demographic models with a realistic soil effect
  • Evaluated the reorganization of forest communities from adult tree to fecundity to seedling recruitment

Additionally, I am analyzing how combined lidar and hyperspectral imagery affect tree fecundity at NEON sites through mastif. I am also quantifying response of ground beetles to habitat characteristics using gjam/gjamTime.

For my doctoral research, I worked with Drs. Conghe Song, Jim Clark, Erika Wise, Diego Riveros-Iregui, and Allen Hurlbert to understand how vegetation phenology responds to climate change, extreme weather events, and urbanization.
