I have lived the majority of my life in the deserts of the western United States. Perhaps living in these unique environments unconsciously fueled my interest in how plants respond to stressful growing conditions. I am particularly interested in plant responses to water stress. Drought and salinity are the major abiotic stresses that result in decreases in crop yield, especially in water limited areas of the world. As potable water becomes less available for agriculture and landscapes we will have to rely on alternative irrigation sources, such as brackish water and grey water. My research covers plant responses (particularly ornamentals) to alternative water sources. My lab is also working on Arabidopsis lyrata, which is a small plant found in many areas in the eastern United States. My work with A. lyrata involves comparing stress response of plants from populations that are found in many extreme environments and trying to determine what adaptations they have developed to the wide variety of abiotic stresses they encounter. In addition, I am interested in the standardization and purity of herbal supplements. As part of this research I have tested supplements that are available over the counter in addition to creating mixed supplements with herbs to determine the detection limits of secondary compound tests.
