Engineer for the Modular Observation Solutions for Earth Systems (MOSES) project working on instrumentation for accessing rapid permafrost thaw.

Fairbanks, Ak

For the Geophysical Institute Permafrost Laboratory, I am responsible for maintenance of existing and deployment of new environmental monitoring stations that measure soil temperature and moisture, air temperature, and snow depth. I have upgraded many of the permafrost observation sites with Iridium satellite transceivers, cellular modems, and radios to enable remote communications and data collection. I also implemented a system for real-time visualization of permafrost data. I have designed and constructed vertical array thermistor probes and other thermistor based temperature sensors for monitoring soil and borehole temperatures. I am responsible for data quality control and management of all our automated observation sites.

● Troubleshooting, routine maintenance, and processing samples on the three continuous flow isotope ratio mass spectrometers (two Thermo Finnigan Delta +XP's and a Micromass IsoPrime) and a dual inlet isotope ratio mass spectrometer (Micromass Optima) and their associated peripherals (two Elemental Analyzers, a Thermo Finnigan Gasbench II, a Thermo Finnigan PreCon, and a Thermo Finnigan High Temperature Conversion Elemental Analyzer). ● Off-line sample preparation including cryogenic water extraction and zinc reduction for δ2H analysis.● Responsible for: day-to-day lab operations including ordering supplies and equipment; supervising and training student workers and other lab visitors; data management and normalization relative to international standards; and quality control / quality assurance.

Laramie, Wy

● Responsible for: day-to-day lab operations including ordering supplies and equipment; and overseeing student workers.● Worked with HYDRUS 1D to simulate water flow under differing watering regimes, soil types, and plant cover. ● Helped construct a database with ecophysiological data for a four desert data synthesis.● Built the lab web-site using Adobe GoLive.

Tucson, Arizona Area

● Setup and maintained up to 7 eddy covariance systems to measure land atmosphere fluxes of CO2 and H2O. In addition basic meteorological parameters (air temperature and humidity, wind speed and direction, precipitation, soil moisture and temperature, etc...) were measured at all sites. ● Built, installed, and maintained sap flow sensors (heat balance and heat ratio methods) to measure transpiration and hydraulic redistribution in trees and shrubs.● Designed and constructed automated soil respiration chambers for the measurement of CO2 efflux from the soil. ● Developed a model using Matlab and ArcGIS to estimate evapotranspiration for San Pedro riparian corridor using satellite and ground-based data. ● Outstanding and superior annual performance awards in all years of employment.

Tucson, Arizona Area

● Worked as part of a multi-agency collaboration of ecologists and hydrologists to investigate the water balance of a riparian ecosystem in Southeastern Arizona. As a part of this group I: ○ Utilized the Heat Ratio method of sap flow to measure whole tree transpiration in mesquite trees at three different sites.○ Made allometric measurements to create scaling relationships between tree diameter, xylem area, and leaf area. ○ Employed the Heat Balance method of sap flow to measure canopy level transpiration in mesquite trees in a riparian floodplain.● Designed, constructed, and assisted with the implementation of an automated vapor collection system used to partition water vapor fluxes using stable isotopes of Hydrogen and Oxygen.● Assisted with day to day lab operations which included: ordering materials and supplies; repairing equipment for lab and field use; and updating, repairing, and backing up computers as needed. ● Audited two plant physiological ecology classes, Functional Ecology of Aridland Plants and Plant-water interactions across multiple scales.
