MDI Biological Laboratory

MDI Biological Laboratory will continue to relentlessly pursue answers to many of our most pressing and complex biological problems. And, as we have done for over 100 years, we will continue to provide a place for leading scientists to carve out time for reflection, collaborate with colleagues, make new connections, vet ideas or learn new techniques.

About MDI Biological Laboratory

MDI Biological Laboratory is a non-profit, international hub for the study of aging, regeneration and environmental health. Our state-of-the-art facilities support 10 research groups whose faculty and students are pushing the frontiers of biomedical science.

We work to improve human health by illuminating the biology of development, aging and regeneration, and by identifying risks posed by environmental toxins.

We are committed to making transformative discoveries that will benefit medicine and society. We are equally committed to mentoring and hands-on training for young people who will be in the vanguard of a revolution in human health.

A Formula That Works

MDI Biological Laboratory was established in 1898 with the belief that removing obstacles to biomedical research leads to faster, bolder discoveries and solutions.

Our research faculty works with diverse models for human health, from salamanders to lab-grown tissue, to define mechanisms of biological damage, repair and regeneration.

We lead a network of 17 Maine institutions training the next generation of science leaders, and we are engaging our community with Science Cafe lectures, conferences and hands-on science to explore human and environmental health.
