Work experience

• January 2021 - July 2022: Laboratory and Field Technician, Eel River Critical Zone Observatory
  • Served as primary manager of field sampling, sample storage and data organization for the Eel River CZO on multiple long-term research projects, including: collection of tree cores/twigs and water samples from the vadose zone and groundwater for δ²H and δ¹⁸O isotopic analysis; collection of samples for carbon stable isotopes, cations, anions, organic acid, pH and alkalinity, total carbon, total nitrogen and inorganic nitrogen
  • Analyzed isotopic data for hydrogen and oxygen stable isotopes with R. Reported progress on sample collection and processing on a weekly basis to the lead PI, and distributed data among a team of 5 other PIs and 4 graduate students regularly.
  • Ordered field and laboratory supplies, contacted suppliers to fix/troubleshoot equipment errors and worked with project members to catalog each sample collected as a part of the Eel River CZO program from 2015-2021
• August 2018 - January 2021: Student Research Assistant, Eel River Critical Zone Observatory
  • Assisted the field technician at for the Eel River CZO.
  • Collected tree cores/twigs for cryogenic extractions.
  • Extracted water from samples using the cryogenic extraction method and prepped water samples for infrared mass spec analysis at the Center for Stable Isotope Biogeochemistry at UC Berkeley.
  • Managed and regularly entered data into project database.
  • Distributed data among 5 PIs and 4 graduate students and presented updates on field work and lab work to project members during monthly meetings and annual retreats.
  • Analyzed isotopic data in R.
