Current Research

Dr. Pan is currently a senior research scientist with the Climate, Fire, and Carbon Cycle Sciences group of the Northern Research Station, USDA Forest Service, and Associate Faculty at University of Pennsylvania. She is a member of the U.S. Government's Carbon Cycle Science Steering Group, member of the Global Forest Expert Panel (GFEP) on Biodiversity, Forest Management and REDD+ (the Collaborative Partnership of FAO, IUFRO, UNDP, UNEP, World Bank etc.), member of the Editorial Boards of the ESA journals, Ecosphere and Ecological Applications, as well as Associate Editor of the Journal of Geophysical Research-Biogeosciences. Her research projects primarily include, but are not limited to,

  1. Biological responses of terrestrial ecosystems to multiple environmental stresses with emphasis on understanding complex interactions among biotic and abiotic processes and between ecosystem structural and functional dynamics;
  2. Regional and continental terrestrial carbon dynamics, and the magnitude and causes of carbon sinks/sources on the land, analyzing the relative importance of the factors that regulate terrestrial uptake of C including natural disturbances, LULC, climate variability, increasing CO2 concentration, N deposition, and tropospheric ozone.
  3. The global forest carbon budget and the role of forests in the global carbon cycle, including assessment of forest carbon management strategies for mitigation, and the UN REDD+ Program.
  4. Modeling and forecasting complex effects of land use, climate and air pollution, particularly nitrogen deposition, on the health of forested watersheds and the effects of watershed forests on the micro-scale stream environments and aquatic organisms.

Her research is highly interdisciplinary in nature and has integrated intensive field studies with modeling approaches, combining strengths of both process- and statistical-based methods with hierarchic observations and measurements from forest inventories, eddy flux towers and remote sensing to understanding how ecosystems function across multiple scales. She has been involved in a series of collaborative projects for understanding and quantifying the impacts of climate changes on forest ecosystems and watershed health in Northeastern and the Mid-Atlantic regions, and for North America. She has also worked on the global forest C analyses with colleagues from around the world. She has been a PI and Co-PI of several NASA projects and USFS Climate Change Research Grants.

National Research Highlights

Effects of Disturbance, Climate, and Management on U.S. Forest Carbon (2012)
Forest response to fire, insects, harvesting, etc., is responsible for nearly one-half of the U.S. forest carbon sink, offsetting about 12 percent of U.S. fossil fuel emissions

Global Forests Sequester One-third of Annual Fossil Fuel Emissions, Much More Than Previously Thought (2011)
Forested land plays a much larger role in removing carbon from the atmosphere than was previously thought, according to Forest Service scientists working with an international team of scientists. One of the key findings in the study is that global forests have annually removed 2.4 billion tons of carbon (8.8 billion tons of carbon dioxide) from the atmosphere, about one-third of annual fossil fuel emissions for the period of 1990-2007.
