Areas of Interest
Broadly, I seek to improve our understanding of the complex and interconnected microbial communities of the built environment by leveraging techniques from microbiology and bioinformatics. My two primary foci are viral-bacterial interactions in drinking water and fungal community ecology in homes. In addition to using more traditional microbiological methods, I am particularly interested in applying next generation sequencing, machine learning, and network modeling to these areas.

Research Projects
My postdoc work is part of the Blue Sky initiative and focuses on characterizing and understanding the interactions between bacteria and virus in drinking water using tools from microbiology and bioinformatics, including metagenomics and network modeling.

For my PhD dissertation, I focused on improving our understanding of fungi in the built environment with two specific aims:
1. using metatranscriptomics to determine whether water activity modulates fungal toxicity
2. characterizing the differences in fungal ecology between homes with and without mold damage in order to build a machine learning tool capable of correctly classifying which homes have mold damage
