Tyson Chiaro

Tyson Chiaro, M.S.

Graduate Student

I study common members of the mycobiota within the mammalian gut, namely Candida spp. and S. cerevisiae. I am interested in how these organisms and their secreted products influence purine metabolism in the host. I am also studying how bacterial and fungal species communicate in the gut and what impact this has on their own physiology, as well as how this changes their ability to be recognized by the host

Additional interests

snowboarding, hiking, camping, and live music.

Garrett Brown

Garrett Brown, B.S.

Graduate Student

I am interested in learning how the virome interacts with bacterial members of the microbiota to influence disease processes.


Carlos Neto

Joao Carlos Gomes Neto, Ph.D.

Postdoctoral Fellow

I am interested in the mechanistic role played by intestinal symbionts in modulating the gut-and-brain axis function, specifically in the context of CNS inflammation elicited by viral infection.

Zac Stephens, Ph.D.

W. Zac Stephens, Ph.D.

Research Assistant Professor

NCBI publications

I study mechanisms by which host-associated microbial communities can be recognized and shaped by host immune cells, and in turn, how microbial communities can shape host intestinal development and disease.

Additional interests

Design and testing of S. cerevisiae fermented oligosaccharide-rich medias (aka beer brewing), hiking, camping and exploring the amazing Mountain West, and Snowboarding.

Rickesha Bell

Rickesha Bell, B.S.

Laboratory Specialist

I manage and maintain the lab’s gnotobiotic facility and assist lab members with their research.

Additional Interests

I enjoy weight lifting, aerial fitness, being outdoors, and spending time with family and friends.

Kyla Ost

Kyla Ost, Ph.D.

Postdoctoral Fellow

My research focuses on host/fungal interactions in the intestinal microbial community. I am exploring both fungal and immune factors that alter this interaction and affect human health.
