Biography

I am a broadly trained ecologist interested in understanding how the function and structure of the forest ecosystem respond to global change at regional to global scales. I will be joining the Department of Ecosystem Science and Management at Penn State University in Oct 2022. I am looking for a postdoc and graduate students, please contact me if you are interested.

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
  • Uncovered the climate-habitat interactions that govern abundance change of ground beetles to climate warming.

The other ongoing projects include:

  • Quantifying the effects of adaptive benefits, climate, and soil on tree masting at a global scale.
  • Deriving canopy nutrients based on combined LiDAR and hyperspectral remote sensing and quantifying their impacts on tree fecundity at NEON sites through mastif.
  • Modeling the response of ground beetles to remotely sensed habitat.

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.
