My research program concerns the influences of contaminants on living organisms.  My research background is in dragonflies, fishes, amphibians, and pigs though I am not limited to those taxa.  Some of the approaches I have taken to answer questions have used behavior, physiology, histology, and/or morphometrics.  
   

 

 

 

 

 

 

 

Specifically,

 I aI I am interested in developmental toxicology –how exposure during critical periods can have long lasting effects even after the exposure is over. 

·        Another area I’m interested in is how stress affects an organism’s response to contaminants.

o       For example, it has been well demonstrated that people that live in poor conditions (rough neighborhoods, poor nutrition, and little/no medical care) tend to suffer more from environmental pollution than people living in affluent conditions exposed to the same exact environmental pollution.

­       I’m currently planning a project using a model organism to tease apart the effects of psychosocial stress and physical stress in how individuals respond to contaminants.

·        Locally, I’m concerned with lead contamination and its effects on children.

o       Beaumont lies between Galveston, TX and New Orleans, LA, two places that are currently reporting 15-20% of their children having blood lead levels above EPA action limits.  -that’s 20% of the population that will suffer lowered IQ, social impairments, and poor school performance simply because of where they grew up-

·        C:\Documents and Settings\pjbryer\Desktop\austin_logo.gifCoal-tar based pavement sealants are currently used throughout the country as a method of preserving asphalt parking lots.  Turns out that the coal tar component can contribute high levels of PAHs to the rainwater that washes over the parking lot and into the storm drains.  Since many storm drains empty straight into freshwater streams these coal-tar pavement sealants appear to harming the native invertebrate communities.

Students: I am new to the faculty and don’t yet have the ability to take on students.  Once my lab has been built (late Fall 2009) I welcome interested undergraduates and graduate students.  Projects in this lab could be very beneficial to students looking for research experience for applications to other graduate programs and medical/veterinary schools.
