Main Focus:

As a modeler of both terrestrial biosphere model (QUINCY) and 3-D chemical transport model (GEOS-Chem), my studies aimed to better understand the interactions among atmospheric chemistry, biosphere and climate. Particularly, I am focusing on the following three perspectives:

1. How global nitrogen cycles influences terrestrial carbon sinks, atmospheric compounds and climate?

I'm interested in the budgets of all N-related gases (e.g. NH3, NOx, N2O), including emissions from anthropogenic activities, soil and biomass burning; atmospheric transport and chemical reactions; as well as how they influence terrestrial carbon sinks and climate. As one of the members in the NMIP2 project (led by Prof. Hanqin Tian in Boston College), I'm now working on exploring the net climate effects of anthropogenic reactive nitrogen. 

2. How air pollution influence terrestrial carbon sinks?

Air pollutants could perturbate terrestrial carbon sinks through N deposition, aerosol radiative diffusion and ozone (O3) damaging.  I'm now working to develop an emission-driven method to better quantify the total impacts of air pollutants on terrestrial carbon sinks. 

3.How extreme climate events influencing air quality through atmosphere-biosphere interaction?

Followed by my Ph.D. work, vegetation could influence O3 concentrations through changing BVOCs emissions and dry deposition. These two processes could dramatically response to extreme climate events, such as heat wave and drought, by coupling to biosphere disturbances. My work aim to better understand such interactions and try to quantify impacts on regional air quality. 

At the same time, I'm also involved in a model development project, ESM2025, to couple C-N-P fully-coupled terrestrial biosphere model (QUINCY) into next generation earth system model ICON (QUINCY-ICON-Land), to better understand how N dynamic feedback to the whole earth system.
