I am currently interested in herpetology with a focus on the phylogeography and impact of fire on the effective population sizes of a lizard with a sky island distribution in Southern California, the effect of wetland habitat restoration on a population of a threatened frog species in a California coastal dune complex, and the disease ecology of a California newt species and a yet to be identified pathogen that causes abnormal skin lesions. 

Tatum Katz is a 5th year PhD candidate. She studies vectors and reservoirs of the amphibian-killing pathogen Bd, specifically by using field data to parameterize and ground-truth a variety of statistical and mathematical models which investigate how these alternative sources affect amphibian population dynamics. She also recently earned her M.A. in statistics here at UCSB, and is excited by all types of statistical analyses, especially machine learning

Amphibian disease ecology

I am broadly interested in disease transmission dynamics, specifically how host community composition alters the prevalence of tick-borne pathogens. Previous research of mine has investigated the host-vector-pathogen interface by examining the effect of larval host blood meal identity on tick nymphal vector competency to Borrelia burgdorferi. 


I am interested in how the genetics of host-pathogen interactions drive disease dynamics in wildlife populations, and how this can be used to inform species conservation and disease management plans. I am currently studying the genetic determinants of host susceptibility and pathogen virulence in the amphibian-chytridiomycosis system across various frog populations in California.
