Current Research Interests are focused on the health, genetic and behavioral aspects of performance in detection dogs. I followed the health and behavior of the search dogs following the 9/11 response. We established the AKC CAR Detection Dog DNA Bank to study the genetics of complex behavior. We conducted a DOD funded field study of the effect of different hydration strategies on performance, hydration, and inflammation in detection dogs. Opened Sept 11, 2012, the Penn Vet Working Dog Center integrates the science and field experience to breed, select, raise and train dogs to use their noses to detect things (e.g. explosives, drugs, people, and even cancer and infectious diseases). The Penn Vet Working Dog Center is a resource for behavioral, nutrition, development and conditioning studies in dogs being trained for detection work. In addition, the interactions between dogs and humans are being studied.
In addition, clinical research in emergency care of dogs and cats, sepsis and trauma continue to be of interest.

Previous Research Focus
-Regulation of nitric oxide synthesis.
-Intermittent hypoxia as an inflammatory stimulus.
-Acute lung injury
Previous Research Summary:
The effects of intermittent hypoxia on regulation of inflammatory mediators, acute lung injury and nitric oxide synthesis was the main interest of the laboratory, but the laboratory is no longer actively pursuing this direction.
Possible Lab Rotation Projects:
none currently available; however field research at the Working Dog Center is possible.
