Relevant Work Experience

1999-2004: Biologist - USDA, Agricultural Research Service, Ft. Pierce, FL

• Field test design layout and incorporation related to developing pest control measures that have reduced environmental impact relevant to weed and pathogenic fungi/bacteria control
• Versed in field scoping and monitoring techniques used in study of problematic weed, insect and pathogenic fungal species
• Designed, planned, and performed vegetation surveys (and associated vegetation mapping) using quadrat method, line transect method, etc., and calculated/analyzed all data related to density, dominance, frequency, and/or importance value for species of interest or concern
• Data collection and analyses related to plant vigor, plant yield (tomatoes and peppers), root system vigor, fungal and bacterial presence/absence in soil and/or on plants
• Data collection and subsequent analyses related to culturing and identification of various fungal pathogens
• Experimental design and implementation of various tests designed to study the effects of experimental biocontrol agents on pre- and post-emergent stages of various problematic weed and fungal species
• Taxonomic identification of exotic and native plant species found throughout the state
• Adept in recognition and treatment of several problematic weed (endemic/native and exotic), insect, fungal, and bacterial species found in Florida (locally and intrastate)

 1993-1999:  California Polytechnic State University, San Luis Obispo

• Designed/conducted research project related to vegetation survey of a 640-acre ranch to assess the flora species composition of the known wildlife corridor and to assess the overall health/vigor and suitability of plant communities for sustaining wildlife populations

• Theoretical and practical training in:  habitat management, environmental impact analysis, plant taxonomy, plant physiology, plant pathology, field botany, ecology and systematic biology, various biological/vegetation mapping techniques for resource areas, edge diversity indexing, point-habitat and zone-of-influence procedures
