Research Interests

I have the good fortune to be both a pharmacologist and a practicing dermatologist.  In addition to serving as Professor and Chair of the Department of Pharmacology & Toxicology, I am Professor of Dermatology and also hold a part-time 5/8th Staff Physician at the Dayton VA.  I see dermatology patients in both the WSU Department of Dermatology as well as at the Dayton VA Medical Center.

There are two major research interests of my laboratory.  First is the pharmacology of the lipid mediator Platelet-activating Factor (PAF).  We have demonstrated that PAF and related oxidized glycerophosphocholines (Ox-GPCs) are produced in response to numerous pro-oxidative environmental stimuli from UV radiation to chemotherapy and cigarette smoke exposure.  PAF-receptor agonists exert acute pro-inflammatory and delayed immunosuppressive effects.  Our models range from cultured cells to mice to humans.  These studies are supported by NIH R01 HL062996, and VA Merit 510BX000853.

The second research area is to define the role of dermal fibroblast senescence in abnormal UVB responses associated with geriatric skin.  In a long term collaborative study with Dr. Dan Spandau at Indiana University, we have defined that geriatric skin responds to UVB differently than young skin, due to differences in IGF-1 levels produced by dermal fibroblasts.  Moreover, we have found that wounding the skin via dermabrasion or fractionated laser resurfacing can result in increased dermal IGF-1 levels and normalization of the abnormal pro-carincinogenic UV response associated with geriatric skin.  We see this as a potential preventative treatment for non-melanoma skin cancer.  Moreover, we have ongoing collaborations with Dr. Young Kim (Purdue University Engineering) using non-invasive mesocopic imaging to quantify photodamage in human subjects.  These studies are supported by NIH R01 AG048946, and VA Merit 1101CX000809.

In addition to these research interests, I have clinical expertise in inflammatory skin diseases, in particular atopic dermatitis and psoriasis.  I direct the Wright State Pharmacology Translational Unit (PTU) which conducts translational research studies and pharmacetical-funded clinical trials.  Please see the PTU website
