Sand Photography

“Photographing sand under the microscope is a hobby I started in late 1999 with samples I collected or received from friends. As a veterinary toxicologic pathologist I have access and working knowledge of microscopy equipment and that, together with experience in photomicroscopy, has provided an opportunity to learn about geology and marine biology in examining different sand samples. My interest as a novice in sand has remained keen and I have basically emulated existing and well established professional and active sand related websites to help share the variability and beauty of microscopic features of sand. Creating is also my way of thanking those who have provided sand samples by featuring their contributions.”

Robert Maronpot Toxicologic Pathologist

Robert R. Maronpot, DVM, MS, MPH, DACVP, DABT, was selected by the Awards Committee as the 2008 Society of Toxicologic Pathology Achievement Award recipient. Dr. Maronpot has significantly influenced the field of toxicologic pathology in many different ways, including as a leader, manager, educator, and author. He is internationally recognized and highly respected for his scientific contributions to toxicologic pathology and the advancement of the Society of Toxicologic Pathology (STP). Dr. Maronpot served as president of STP in 2001 and as editor-in-chief of its journal, Toxicologic Pathology, from 2001 to 2004.
Dr. Maronpot received his doctorate of veterinary medicine in 1965 from Michigan State University, an MS in nutritional pathology from Michigan State University in 1966, and an MPH from Harvard University in 1972. He is a diplomate of the American College of Veterinary Pathologists as well as the American Board of Toxicology and has worked more than forty years in experimental pathology, with an emphasis on animal models of carcinogenesis. He serves on several journal editorial boards.
In addition to more than 300 peer-reviewed publications, he has edited a comprehensive text titled Pathology of the Mouse (1999), coedited a book titled Pathology of Genetically Engineered Mice (2000), and has several years of experience in the application of imaging technologies, especially magnetic resonance imaging (MRI), to toxicologic pathology. In 2007, he retired from the National Institute of Environmental Health Sciences (NIEHS) and the National Toxicology Program (NTP), where he was chief of the Laboratory of Experimental Pathology.
As a leader and manager, he started at the NIEHS as part of a very small, fledgling program of experimental pathology in 1981. During his appointment, his vision of increasing the impact of the pathologist in toxicology through a wider use of scientific tools was so successful that, by the end of his tenure, the program had expanded to fifty people, all dedicated to the elucidation of scientific issues in pathology. The pathologists on the current staff at NIEHS joined the program during his tenure and constitute a remarkable group of scientists.
As an educator, Dr. Maronpot also created the training program at NIEHS, where many toxicologic pathologists have been trained through the years. The program maintains two to three trainees, therefore creating a scholarly learning environment. He was the originator of the NTP Symposium held in conjunction with the
