Dr. Christopher M Gray
About
Since 2019, I have had the pleasure of being the COO and co-owner of Twin Arbor Labs, an analytical and microbial testing laboratory for multiple industries including supplements, cosmetics, beverages and food. I previously founded Platon Science and Technologies with the goal of advancing vapor analytical techniques. This was done with start-up funding from an N-STEP government grant following a NRC postdoctoral research associateship at the National Institute of Standards and Technology (NIST) in Boulder, CO. I received my Ph.D. from the Ecology and Evolutionary Biology department at the University of Colorado under the direction of Noah Fierer at the Cooperative Institute for Research in Environmental Sciences. Studies included microbiology, soil ecology, and statistical analyses of large data sets. My dissertation research was on the microbial production and consumption of volatile organic compounds in soil and decomposing plant litter.
Education
My dissertation focused on the microbial production and consumption of volatile organic compounds (VOCs) in soil and litter environments. VOCs are reactive lightweight carbon compounds that have implications within atmospheric chemistry, biogeochemistry and soil ecology. In the atmosphere, the breakdown of VOCs leads to tropospheric ozone (smog), increased lifetime of greenhouse gas species, and altered precipitation dynamics through the formation of secondary organic aerosols. Within soils, several have been shown to act as communication pathways between microorganisms and plants as well as inhibiting and stimulating microbial and plant growth.
To study the complex suite of processes associated with VOC dynamics, I have maintained and operated mass spectrometers (PTR-MS and GC-MS) in conjunction with lab and field based experiments. Additional work utilized amplicon sequencing (on the Illumina platform) of soils exposed to varying concentrations of a particular VOC of interest (isoprene) to identify the bacterial and fungal communities involved in the consumption of isoprene within soils. With roughly 50K DNA sequences per sample equating to extremely large data sets, advanced techniques were needed to process and analyze the high-throughput sequence data to quantify shifts in bacterial and fungal communities.

Professional Experience
My professional life began working as an analyst and project manager for Hewlett Packard. To this day I still enjoy working with complex systems and coming up with innovative solutions to difficult problems. Although my time at HP was enjoyable and there was ample opportunity for advancement, I instead decided to further my education before finalizing my career path. I believe that life is one of the most complex systems and climate change is an undeniable threat. This lead me to concentrate my education on further understanding those areas. Postdoctoral work at the National Institute of Science and Technology broadened my experience through exceptional mentor-ship from Dr. Thomas J. Bruno. With the founding of Platon Science and Technology, I was excited to once again be in the workforce and contributing to the success of research and business. My experience with Twin Arbor Labs has expanded what I know in many areas of business.

Publications
Gray, C. M., Helmig, D., & Fierer, N. (2015)
Soil microbes were capable of consuming 68% of the gaseous isoprene provided to soils (2–200 ppbv) in a flow-through experiment.
Increases in isoprene levels were associated with significant shifts in the composition of both soil bacterial and fungal communities.
A wide range of taxa were associated with isoprene consumption and many were closely related to known hydrocarbon degraders.
Gray, C. M., Monson, R. K., & Fierer, N. (2014)
Emission rates from the soil were highest for methanol and monoterpenes.
Uptake rates into the soil were highest for isoprene and formaldehyde.
Tree root presence and temperature correlated with volatile organic compound flux rates.
Gray, C. M., & Fierer, N. (2012)
Volatile organic compounds were a significant fraction of the carbon emitted from several of the decomposing litter types examined.
Nitrogen additions decreased net volatile organic compound emissions from litter to near zero.
The decrease in carbon lost as volatile organic compound emissions after nitrogen additions accounted for the well-studied increase in respiration for certain litter types.
Gray, C. M., Monson, R. K., & Fierer, N. (2010)
Volatile organic compound emissions from decomposing litter are primarily from microbial sources.
Methanol was the dominant compound emitted from all litter types studied.
The quantities and specific compounds emitted varied in a predictable manner with litter type.
