Previous Experience

Before he joined the Physics Department in 2011, Dr. Zhang held a postdoctoral Research Associate position at the Goddard Earth Sci. &. Tech. Center of UMBC from 2008 to 2011 and worked onsite at the Climate and Radiation Branch (Code 613.2) of the NASA Goddard Space Flight Center.

Professional Interests

My primary research interest is in cloud and aerosol remote sensing, which aims to quantify global cloud and aerosol optical and microphysical properties using remote sensing technologies, and thereby establish observational-based correlations between the properties of clouds and environmental factors, such as aerosol, water vapor and precipitation. My research is motivated by the fact that the current understanding of clouds, especially with regard to how clouds are connected to the environment and how clouds change with global warming, is highly limited, which has become the major obstacle hampering climate change predictions.

My research started with light scattering and radiative transfer, two of the most fundamental areas in remote sensing. My major contribution in these areas is the development of innovative methods and efficient numerical models for simulating the scattering properties of nonspherical ice cloud particles with complex shapes. Ice particle scattering properties computed using my models are now widely used in ice cloud remote sensing and climate modeling for representing how ice clouds interact with solar and thermal infrared radiation. My current research at UMBC is aimed at characterizing the vertical structure of clouds in different meteorological conditions, using a combination of cloud resolving models and remote sensing technologies. Results from this project will provide a vertical profile of cloud droplet size as a function of cloud type, in order to better represent cloud vertical structure in climate models and to help improve the predication of climate change. In addition to cloud remote sensing, I am also interested in the climatic effects of clouds, aerosols and water vapor.
