Susanna L. Harris is a PhD candidate at UNC-Chapel Hill studying “plant probiotics”. She studies how beneficial bacteria stick to plant roots and whether this community of microbes helps or hurts the plants’ growth. She hopes this research may help develop safe microbes to replace harsh chemicals for increasing crop production. Susanna shares her science online through The SciCommunity on Instagram.
In March 2018, Susanna founded The PhDepression LLC to open discussion of mental illness in Higher Education through curation of stories and resources. She speaks openly about her own depression and mental illness, including in a widely-viewed speech.
