Faculty Profile


The Izard’s laboratory leverages a multi-disciplinary approach to obtain a greater understanding of our microbiome function to empower everyone to nurture a supportive microbiome.
The research topics are centered on the human microbiome along the digestive tract. While we are not losing focus of health and disease, we take in account element of wellness as we face the day-to-day challenges.
The work in the laboratory includes:

  1.  Understanding the effect of diet on the digestive microbiome in altered (ostomates) and unaltered digestive tract,
  2. Studying the dissemination of members of the microbiome,
  3. Improving methodologies related to microbiome studies.
