Anne Estes | Towson University


Dr. Anne Estes is an integrative biologist interested in the effect of the host diet
and physiology on the genome and evolution of the host’s microbiome. The Estes laboratory
examines the effect of diet and antibiotic perturbation of the dung beetle digestive
system microbiome, an insect essential to human and environmental health. These include:
(a) the interaction between a host’s diet and physiology and the diversity, genome
content, and function of its microbiome and (b) the molecular mechanisms facilitating
the establishment and maintenance of host-bacterial symbioses, especially during disturbance
events such as antibiotic exposure.

Dr. Estes earned her B.S. and MS in Biology at Auburn University. She first began
studying insect-microbial interactions during her doctoral work at the University
of Arizona, Department of Ecology and Evolutionary Biology. After completing her doctoral
work, she was a Visiting Assistant Professor at Towson University where she and her
students began working on the dung beetle microbiome.  Dr. Estes learned next generation
sequencing, microbiome analysis, and bacterial genomics as a post-doctoral fellow
at the Institute for Genome Sciences. Dr. Estes is also passionate about science communication.
To that end, she founded and maintains a microbiome science blog – Mostly Microbes – and does guest writing and webinars on the importance of the human microbiome during
early childhood.
