Environmental Science MS opportunity 
Stable isotope atmospheric chemistry
Texas A&M University – Corpus Christi

An Environmental Science MS opportunity is available with the Felix 
Research Group in the Department of Physical and Environmental Sciences 
at Texas A&M University – Corpus Christi.  The position will be funded 
through research and teaching assistantships and has a tentative start 
date of January 2017. The group’s research focuses on using stable 
isotope techniques to investigate the sources, transport, and fate of 
reactive nitrogen and volatile organic compounds in the environment.  
The group’s research across various earth systems provides a unique 
research experience that balances fieldwork with sample processing, 
sample analysis and development of novel stable isotope analysis 
techniques. 

The potential MS student’s research will be part of an existing study 
using stable isotope techniques to investigate ammonia (NH3) emission 
sources in a South Texas coastal urban air shed, Corpus Christi, TX, 
U.S.A.  NH4+ has been documented in the Corpus Christi air shed as a 
significant contributor to PM2.5 and although the area is currently 
within the 3-year PM2.5 attainment rule, there is a reported increasing 
PM2.5 trend in this region.  PM2.5 attainment strategies for urban areas 
will rely on knowledge of NH3 sources and NH3 atmospheric chemistry and 
data provided by this study will provide urban stakeholders with 
potential avenues of NH3 emission mitigation.  

Potential students should be highly self-motivated and have a strong 
background in chemistry with extensive laboratory experience.  The 
project relies heavily on stable isotope techniques so experience with 
these techniques is desired but not necessary.  MS students would 
matriculate through the Environmental Science MS program

  Interested candidates should contact Dr. J. David Felix 
([email protected]) and provide a short statement of interest and 
CV.  More information about the Felix Research Group and potential 
research can be found here felixlab.tamucc.edu.  Information about the
