Education:

2011 Ph.D. Forestry and Natural Resources, Purdue University, West Lafayette, IN.
2006 M.S. Biotechnology, Johns Hopkins University, Baltimore, MD
2002 Certification, Animal Care Specialist, Professional Career Development Institute, Norcross, GA

Research Interests:

Research is centered upon environmentally-induced parameters that differentiate tropical hardwood populations and drive tropical hardwood genetic improvement. Program involves in silica, in vitro, ex vitro and molecular-based data acquisition in addition to field experimentation. Current research projects use NextGeneration technologies to uncover sequencing data related to climate and altitude adaptation.

Current Research Model: Acacia koa (koa).

Acacia koa A. Gray (koa) is a tree species endemic to the all islands within the Hawaiian archipelago but only exists in populations of sufficient size to be called forests on Hawai’i, Kauai, Maui and Oahu. Free-range cattle grazing and over-harvesting combined with invasive grasses have severely crippled koa forests to a point where populations are continuing to decline despite several small-scale restoration efforts. Koa populations also vary along elevational transects therefore attempts will needed to determine which genetic components allow specific trees to survive conditions intolerable to other members of the species.
