Work Experience: Research Specialist (2001 to 2012), U.C. Irvine, Irvine, CA; Primary

responsibilities and contributions included:

1) Design, installation and maintenance of 19 solar powered eddy flux towers

in Canada, Brazil, and California – to measure the exchange of CO2 and

water vapor between the atmosphere and different ecosystems.

2) Development of automated GOES satellite data retrieval software.

3) Developed WiFi data retrieval and platform control system using wireless

serial port servers.

4) Design and manufacture of automated instruments which measure CO2

concentrations as a function of depth and time in soils and traps aliquots of

CO2 for 14C analysis.

5) Design and manufacture of automated systems for measuring soil respiration

(using microprocessor controlled multiplexed chambers) and trapping

respired CO2 for analysis of 14C.

6) Supervising work crew constructing the California Rainout experiment

which intercepts and redistributes precipitation along an elevation transect

in southern California.

7) Designed instrumentation and data acquisition system to measure the effects

of treatments in the California Rainout system.

8) Developed a new method to use water content reflectometers to measure

volumetric water content in soil.

9) Designed a photodiode based sensor to measure normalized differential

vegetation indices by analysis of incoming solar radiation and radiation

reflected from the ecosystem surface.

10) Managed field campaigns and experiments, supervised construction

projects, managed electronic data flow and storage.

11) Mentored graduate and undergraduate students.

Guest Researcher (3 months in 2000 and 2001), Woods Hole Research

Center; Santarem, Para Brazil; solving problems measuring soil moisture with time

domain reflectometry, and developing software for waveform analysis.

Chemist (1991 to 2000); U.S. Geological Survey, National Research Program;

Woods Hole, MA; Support staff for Geochemical Carbon Fluxes Project; Primary

responsibilities included:

1) Design and supervision of the gas chromatography laboratory.

2) Developing methods to estimate soil respiration and soil gas

concentrations of CO2 and CH4 using gas chromatographs and infrared

gas analyzers.

3) Conducting field measurements of soil respiration during the growing

season at Harvard Forest, MA; in the winter through snowpacks for

NASA’s BOREAS Project; and at Sleepers River Research Watershed.

4) Designing an automated system for closed chamber measurements of soil

respiration.

5) Running laboratory operations studying the perturbations of closed

chambers on the transport of gases through porous media.

6) Developed and validated a 'quasi' chromatographic field method to

measure CO2 concentrations in gases collected at different depths from

soils using an infrared gas analyzer as a detector and scrubbed air as the

mobile phase.

7) Developed and tested methods and materials to conduct research in

northern Manitoba at the Army's Cold Regions Research and Engineering

Laboratory in Hanover, NH.
