I am a highly skilled and motivated biologist with twenty years experience in aquatic ecology. I also have experience working in terrestrial systems. I earned both a B.S and M.S in biology with a concentration in conservation/organismal biology from San Jose State University. My current job duties include; leading field crews in data collection, analyzing the data, creating figures and tables, technical report writing, logistics, personnel training, creation of annual project and task budgets, writing proposals, schedule personnel, perform evaluations for annual personnel reviews, and support representation of clients at technical group meetings and field site visits. My areas of expertise are; fish population monitoring, aquatic habitat assessments and mapping, fish age and growth, mark and recapture, macroinvertebrate sampling, biotelemetry, western salmonid ecology, ecology of native fish, special status amphibians, western pond turtle ecology, and abiotic parameters affecting a species and its habitat. My current duties are in support of FERC relicensing, compliance activities for hydropower and water supply projects and infrastructure projects. In addition, I conduct literature reviews on fisheries, river and water-related issues for the California coast, Central Valley and Sierra Nevada foothills as background for environmental documents. I am a member of the American Fisheries Society, The Wildlife Society, The Conservation Society, and the Cal/Neva Amphibian Populations Task Force. Show less

I assisted in trapping adult Chinook salmon on the Guadalupe River in Santa Clara County for implanting internal radio tags and tracking them daily. The goals of this study were to; document and quantify the timing of adult Chinook spawning run in this system, determine habitat use and activity, quantify survival times, locate spawning habitats and determine daily movement patterns in conjunction with environmental variables. I conducted Chinook salmon redd surveys on a weekly basis throughout the Guadalupe River watershed. I also as part of a team, elctrofished these streams using NMFS protocols to collect scale samples from steelhead and determine spawning success of individual salmon redds. I used scale analysis determine age and growth of over 1,000 fish, which included steelhead trout, Chinook salmon and native cyprinids. I also conducted visual estimation surveys for post-metamorphic California red-legged frogs and California tiger salamanders and used seines and dipnets to sample for larvae. I trapped western pond turtles to save individuals from draining of percolation ponds and construction activities. Show less

I constructed and maintained drift fences and pitfall traps for amphibian capture. I captured northern red-legged frog tadpoles and determined their Gosner metamorph lifestage. I characterized terrestrial habitat for northern red-legged frogs, which included the plant community, canopy and substrate. This study was conducted to ascertain survival rates of metamorphs migrating from breeding ponds. Body size, timing, ground moisture, rainfall, humidity, water and air temperature and distance from breeding pond were variables investigated. Show less
