  • Ph.D. Student, Cornell University, Department of Natural Resources (in progress). Advised by Dr. Timothy Fahey.
  • M.S., Cornell University, Department of Natural Resources, Ithaca, New York (1995).
  • B.A., Williams College, Williamstown, Massachusetts (1988). Major in biology, dean's list.

    • Professional Positions:
  • Research Support Specialist, Cornell University, Ithaca, NY. 1997 to present.
  • Teaching Assistant, Environmental Conservation, Cornell University. Spring 1998 and 1994.

    • Research Interests and Activities:
    Currently, my research focuses on investigating the effects of anthropogenic disturbance on belowground productivity and nutrient cycling. Together with a multi-disciplinary team of researchers from Cornell and other institutions, I am investigating the effects of soil freezing on belowground processes in the northern hardwood forest at Hubbard Brook Experimental Forest. Specifically, I use minirhizotrons to quantify fine root dynamics in response to artificial freeze treatments.
