I specialize in stock photography especially digitally-enhanced medical images and digital illustrations of the human body and disease processes. My background in medicine and research allows me to provide my clients with scientifically accurate images backed by professional expertise. I have extensive coverage of digitally enhanced xrays, CT and MRI scans of normal human anatomy and organ systems as well as coverage of important disease processes and pathology. My files include electron microscopy of bacteria and viruses; molecular models of drugs; biochemical compounds, proteins, DNA and toxins; surgery and medical practice in developing countries; and photographs of common disease conditions. Among my nature coverage, I have closeup photos of insects, spiders and invertebrates, edible, medicinal and poisonous plants and mushrooms, snowflakes, killer bees, and agricultural pests, just to name a few.
