Life emerges from the organized flow of energy through biological systems. Cellular energy flow is largely driven by mitochondria, which in turn gives us the ability to sense and perceive, integrate information, adapt, and thrive.

Our team combines knowledge from mitochondrial biology, stress neuroendocrinology, geroscience, network science, and mitochondrial medicine to understand principles of mitochondrial communication and signal transduction. ​We develop new laboratory assays and omics-based computational approaches to explain how psychological states influence biological and energetic processes within mitochondria, and in turn how mitochondria influence mental and physiological functions.

Together with our collaborators, we deploy our mitochondrial phenotyping platform to map inter-individual variation and sex differences in mitochondrial health, to understand mitochondrial plasticity over time, and to map their role in the ​maintenance of human health and aging.

​Our goal is to discover bioenergetic mechanisms of brain-body communication and to use this knowledge to build an integrative model of human health that can help transform how we teach and practice medicine.​

Lab Members

  • Martin Picard, PhD

    • Principal Investigator

    Martin is an Associate Professor of Behavioral Medicine (in Psychiatry and Neurology) at Columbia University Irving Medical Center. He trained as a physiologist in neuroimmunology, then in aging mitochondrial biology, psychosocial oncology, and systems biology at McGill University, Canada. As a postdoc fellow he worked with cellular and animal models of mitochondrial disease with Doug Wallace at the Center for Mitochondrial and Epigenetic Medicine (CMEM), and on stress neuroendocrinology with Bruce McEwen. Beyond his passion for mitochondria and transdisciplinary research, outside the lab Martin enjoys electric cars and renewable energy, and spending time in nature with family.

  • Caroline Trumpff, PhD

    Caroline is an Assistant Professor of Medical Psychology in the Department of Psychiatry. Caroline completed her postdoctoral training as a Herbert H. and Ruth S. Reiner Postdoctoral Research Fellow in the Picard Lab. Caroline received her PhD in psychological sciences from the Université Libre de Bruxelles, Belgium. She completed her doctoral research at the Belgian Scientific Institute of Public Health (Sciensano) where she studied the effects of iodine deficiency during pregnancy on children’s neurodevelopment. Caroline's research aims to understand the interplay of psychological stress exposure and mitochondrial biology as a potential biological pathway linking psychosocial stress to physical and mental health trajectories across the lifespan.
