Richard Pollack is a public health entomologist at the Harvard School of Public Health in Boston, Massachusetts. His studies have focused for
nearly 20 years on insects and other arthropods that affect human and animal health. His
work in both lab and field seeks to define the ecological, behavioral, and physiological
bases that sustain insect-borne pathogens in nature.
Pollack and his colleagues have devoted a section of their Web site to lice
and their treatment (http://www.hsph.harvard.edu/headlice.html). This site has prompted
many parents, school officials, and health care professionals to reexamine their diagnoses
and reevaluate their management strategies.
