Resume/CV

In under two years, we built from scratch (including materials development) and deployed a wireless mesh network of sensors using printed carbon nanotubes to detect methane leaks. The deployment was to the CSU METEC center in Ft. Collins, CO.

PSI-Developed Product Field Deployment

Using the RMLDTM (developed by PSI) to take tomographic scans of simulated methane leaks in an experimental coal mine outside of Pittsburgh, PA.

Deploying the RMLDTM to a coal mine and taking data. Image featured on PSI's website.

Sensors Built & Deployed for my PhD

In-lab soil respiration measurement

In the field measuring soil respiration

First all weather deployment (Beltsville, MD)

Preparing for Hurricane Sandy

MIRTHE instrument after a Nor'Easter

The two CO2 sensors survive a Nor'easter

Real-Time Calibration Technique Developed for my PhD
