     Dr. McDonald is a Scientist and Program Manager of the Chemistry and Inhalation Exposure Program. The program links aerosol technology with specialized exposure systems to provide inhalation exposures to laboratory animals. The Chemistry Core serves a vital role in characterization of dose formulations, aerosols, and concentrations or fate of chemicals in vivo. Research areas span pharmaceutical, environmental/occupational, and infectious diseases. The pharmaceutical research is primarily focused on preclinical evaluation of formulation, pharmacokinetics, efficacy and safety). The efficacy studies include development and utilization of animal models of COPD, inflammation, fibrosis, mucous, and cancer. Pharmaceutical development also lends into on-going research in the discovery and evaluation of new therapeutics against chemical threats (blister/nerve agents), infectious threats (Biosafety Level-3) and radiological threats.

     The environmental/occupational research focuses primarily in development of inhalation exposure atmospheres that mimic real world exposure conditions. These atmospheres are characterized at a high level of detail to enable research on the relationships between chemical/physical composition and biological response or fate in the body. Occupational hazards, including nanoparticles resulting from the nanotechnology industry, are evaluated for their biological compatibility and fate in vivo.
