Balancing the gut microbiome can transform the entire terrain of the body by regulating the immune system, controlling inflammation, influencing metabolism, and affecting brain function via the gut-brain axis, all of which are crucial in the prevention and potential reversal of chronic illnesses. 

Martha Carlin is a pioneering citizen scientist and systems researcher who has spent the past decade unraveling the hidden connections between the microbiome, chronic disease, and environmental toxins. After her husband was diagnosed with Parkinson’s disease, Martha left a successful corporate career to investigate the deeper causes of neurodegeneration and metabolic dysfunction—starting in the gut.

Martha Carlin photo Martha Carlin, is a “Citizen Scientist”, systems thinker, wife of Parkinson’s warrior, John Carlin, and founder of The BioCollective , a microbiome company expanding the reach of science and BiotiQuest, the first of it’s kind probiotic line. Since John’s diagnosis in 2002, Martha began learning the science of agriculture, nutrition, environment, infectious disease, Parkinson’s pathology and much more. In 2014, when the first research was published showing a connection between the gut bacteria and the two phenotypes of Parkinson’s, Martha quit her former career as a business turnaround expert and founded The BioCollective to accelerate the discovery of the impact of gut health on all human disease. Martha was a speaker at the White House 2016 Microbiome Initiative launch, challenging the scientific community to “think in a broader context”. Her systems thinking background and experience has led to collaborations across the scientific spectrum from neuroscience to engineering to infectious disease. She is a respected out of the box problem solver in the microbiome field and brings a unique perspective to helping others understand the connections from the soil to the food to our guts and our brains.
