Dissolved organic matter (DOM) is the soluble fraction of natural organic matter (NOM) that plays a significant role in numerous biogeochemical interactions in surface water and groundwater environments. A major portion of Dr. Dee’s research involves investigating DOM source (terrestrial and aquatic sources), seasonal and climate controls (seasons and drought), hydrology (snow-melt and stream-groundwater interactions), and complexation reactions with metals and particulates (colloids and sediment).
