The research interests of my lab are:

  1. To integrate proximal and remote sensing and process-based models to improve the fundamental understanding of water, carbon, nutrient, and energy cycles under climate change and human disturbance
  2. To combine soil sensing technologies, big data analytics, and machine learning to monitor, model, and map water, carbon, nutrient, and energy fluxes across scales for sustainable natural resources management

Figure 1 Dr. Huang is installing in situ soil moisture sensors in an irrigated sandy field, in Hancock, WI. The soil moisture measurements collected by the sensors will be used to evaluate models established using satellite data to map soil moisture dynamics at the field scale (Figure 3).
Figure 2 Dr. Huang is collect ground-based measurements of soil electrical conductivity using a non-invasive electromagnetic induction sensor (DUALEM21s) in Hancock, WI. The measurements collected by the sensor will be used to generate maps of soil physical and hydraulic properties at multiple depths (0-3 m) at the field scale.
Figure 3 NASA SMAP satellite and a map of surface soil moisture (SSM) generated using in situ soil moisture sensors and SMAP data at the field scale in Wisconsin. The fine-resolution (100-m) map of soil moisture empowers growers to automatically apply irrigation water at the right time, right rate, and right place to save water, electricity, and labor, maximize the crop yield and reduce nutrient loss and environmental contamination.


Currently, I work on several projects to use proximal and remote sensing, process-based models, machine learning, and big data analytics for soil moisture and water and nutrient fluxes modeling, mapping, and management in Wisconsin, across the US, and globally.
