Stephen Sassman Analytical Chemist |
My primary research
interest is the development of analytical methodology for analysis of
environmental samples using liquid or gas chromatography coupled with mass
spectrometry. I am investigating the occurrence and fate of endocrine
disrupting compounds originating from confined animal feeding operations.
Another project under investigation deals the presence and degradation of
halogenated organic pollutants in environmental samples. I am also
responsible for teaching graduate students how to use the analytical
instrumentation and performing regular maintenance on the instruments.
Currently, I am in charge of maintaining several gas and liquid
chromatographs, a liquid chromatograph tandem mass spectrometer, a gas
chromatograph tandem mass spectrometer, an atomic absorption spectrometer,
and an inductively coupled plasma mass spectrometer. I obtained a Master of
Science degree in chemistry from Texas State University in 1999, and came to
Purdue in 2000 to work as a laboratory manager for Dr. Linda Lee. I operate
a <a href=”http://www.analyticalchem.com”>website dedicated to analytical
chemistry</a> which runs on a linux server in my spare bedroom. More
information about me including my resume is available at my <a href=”http://stephen.homeip.net”>personal
website</a>. |

Claire Simond
Visiting Scientist |
I obtained a master’s degree in ‘Environmental Sciences and Engineering’ from the Swiss Federal Institute of Technology in Lausanne, Switzerland, in August 2008. Since September 2008, I have been working as a visiting scientist in Dr. Lee’s lab. During my stay, I am analyzing nutrients and hormones from ditch water. As an Environmental Engineer, it is important to understand how samples are analyzed to be able to give a correct interpretation of the results. At Purdue, I am also working for Dr.Chaubey in Agricultural and Biological Engineering in a domain related to ditch water as it is about constructed wetlands treating field runoff water for nutrients removal. The chance I have to work at Purdue prepares me for a future Ph.D back in Switzerland. |

Xianliang Qiao,
Visiting Scholar |
My research interest is the environment behavior and ecological effects of emerging organic pollutants like hormones and antibiotics, which are mainly discharged from the confined animal feeding industry and municipal wastewater treatment plants. During my visit at Purdue University, I will focus my attention on the sorption of typical hormones and antibiotics by diverse natural sources of dissolved organic matter (DOC) using dialysis techniques. This data will be helpful in assessment the effect of DOC on the mobility of hormones and antibiotics in the environment. |
