Dr. Sarah Placella founded Root Applied Sciences after realizing that farmers struggle to get the information they need to make informed decisions for pest control. She applies the techniques she learned as a scientist and researcher to provide actionable insights to growers, using a device that measures airborne fungal spores.


Sarah worked at startups in biotech and agtech before starting Root Applied Sciences.


She has a PhD in soil microbial ecology from UC Berkeley and a bachelor's degree in Earth and Planetary Sciences from Johns Hopkins University. She has had visiting scholar appointments at Michigan State University's Kellogg Biological Station and at INRA in Montpellier.
