Short Biography

Barbara grew up in northern California, where she learned to appreciate the value of water.  She received a B. Mus. in performance at Boston University; in 1986 she moved to Austin, Texas.  Combining her interest in water, mathematics, and the outdoors, she enrolled at the University of Texas and received her Masters and Ph.D. degrees in Geology, with an emphasis on karst hydrology.  Her principal research interests are water quality of karst systems and source and fate of contaminated sediment.
