Neon Temporary Field Technician (Limnology & Forestry)Neon Program Mar 2016 - Jul 2016Boulder, UsPromoted to Lead Technician.NEON’s mission is to enable understanding and forecasting of the impacts of climate change, land use change and invasive species on continental-scale ecology. They accomplish this by providing infrastructure and consistent methodologies to support research at 106 terrestrial and aquatic sites across the USA.♦ Implemented standardized forestry techniques (FIA) to monitor the health and structure of forest density, biomass, and diversity ♦ Collected data on water quality, aquatic plants and algae, aquatic macro and micro invertebrates, algae♦ Analyzed species composition, height, and percent cover of Colorado alpine, subalpine, montane, and grassland plants♦ Followed strict protocols to analyze plant diversity, vegetation structure, plant biomass, and phenology in field and lab -

Research InternThe Bottlenose Dolphin Research Institute Aug 2014 - Nov 2014Studied under head researcher Bruno Diaz Lopez to investigate questions surrounding the influence of human activities and the behavioral flexibility of bottlenose dolphins. Observed behavior, counted individuals, matched photo identified individuals to catalog, and transcribed continuous behavioral data while on-board the research vessel.♦ Collected 20-minute environmental surveys during field work, capturing such data as Douglas Sea Scale, wind speed, marine bird species, number and type of boats in the area, water pH, salinity, conductivity, and GPS position♦ Analyzed fish otoliths within stomach contents of stranded bottlenose dolphins♦ Worked closely with a team of 5 – 8 interns and researches for extended periods in close quarters
