I am a physician trained in allergy and immunology with an expertise in the consequences of bites, stings, infestations, and other contacts from insects and other invertebrates. As a part of the BugGuide team of volunteers that maintains this website, I try to raise awareness of the fascinating world of arthropods that surrounds us, and do my best to bring useful information to those requesting it through this website. If you have found this website useful, please consider supporting it.

I received a BS in entomology (with high honors in microbiology) from the University of Maryland and subsequently moved to New Orleans where I got an MD (specialty in pediatrics, subspecialty in allergy/immunology) and a PhD (parasitology).

I've developed an interest in linking the lesions of witnessed arthropod bites and stings to individual arthropod species. I have written a book chapter on this subject, and one case report stemming from a specimen posted to BugGuide several years ago.
If you have images of skin reactions linked to particular species, I would like to see them. Send images to: Please contact me prior to sending actual specimens by mail. I will generally only provide medical opinions to physicians.

I am currently attempting to "curate" the cockroaches on BugGuide. The following are notes to myself about images that I am working on:
