If chemical cartography is a new term to you, you’re likely not alone. In this episode Paolo talks with Dr. Laura-Isobel McCall about what chemical cartography is and how it’s helping us start to better understand an organism’s complex and location-dependent response to external stimuli such as simple chemicals as well a pathogens. The conversation touches Dr. McCall’s fundamental LC-MS metabolomic work, its use and application through chemical cartography to understanding Chagas disease, and to the ethical concerns of using highly personal metabolomic fingerprinting data.
