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 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 use 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 
TAMU-CC isotope core facility can be found here http://icl.tamucc.edu/.
