ELLEN-THÉRÈSE LAMM, HISTOLOGY LAB MANAGER

Ellen-Thérèse Lamm, Histology Lab Manager, Museum of the RockiesEllen-Thérèse Lamm hails from the ‘Garden State,’ but has dreamed of the ‘Treasure State’ since the age of six – when she first saw photographs of Glacier National Park.  The gift of a microscope, for her tenth birthday, helped her to discover another passion – cell biology.  Ellen-T’s work at the Museum of the Rockies (MOR) has enabled her to combine both.

At Rutgers-Cook College in NJ, Ellen-T gained extensive experience with large and small animals, under veterinary, farm, and laboratory conditions, and participated in research studying hypertension and the microanatomy of the adrenal gland.  While an undergraduate, Ellen-T enjoyed her first Montana adventure working on the Wolf Ecology Project in Glacier National Park during the summer of 1986.

In 1991 Ellen-T joined Jack Horner at the Museum of the Rockies, as his research was redefining our understanding of dinosaur behavior.  Ellen-T began instructing students in paleohistology techniques, enabling exciting discoveries about dinosaur physiology, growth, and behavior through examining microscopic structure of fossilized bone, ossified tendons, eggshell, and teeth.

To date, our MOR Histology Lab has collaborated with researchers at over 100 institutions around the world. Over 2,500 specimens have been thin-sectioned, and thousands of slides cataloged, creating an extensive reference library of fossil tissue structure.  Requests for the use of MOR’s histology lab and collections are increasing, with a new generation of students and visiting researchers seeking training and access to one of the largest, most comprehensive histology collections in the world.
