Join Us in Celebrating 100 Years of Science!

From pioneering research to groundbreaking solutions, UMCES has long been at the forefront of understanding and addressing the needs of our natural world. Today, our mission to safeguard the environment and drive innovation has never been more urgent. Join us as we embark on the next 100 years of advancing science, empowering communities, and building a brighter, more sustainable world for generations to come!

1925 - A Legacy Begins

The world’s smallest creatures are often the loudest harbingers of things to come. In Maryland, one man’s focus on the fate of tiny oyster larvae in the Chesapeake Bay one hundred years ago spawned a modern global research enterprise that today addresses the most pressing environmental challenges of our time. 

Working from a donated building in Solomons, Maryland in 1925, Chesapeake Biological Laboratory founder Reginald Truitt could not have imagined his legacy would include preeminent environmental researchers embedded in labs across Maryland, leveraging the state’s commitment to its natural resources into making the Chesapeake Bay watershed the model for successful ecological restoration efforts around the world.

Expertise for a Changing World

From concerns about oyster population depletion at its founding and the disappearance of sea grasses in the 1970s, to the application of environmental DNA research and unprecedented use of data science technologies today, UMCES scientists represent a depth and breadth of experience unique to its singular environmental  focus

Deeply committed to the discovery and application of sound scientific solutions to society’s most complex socio-environmental needs, UMCES’ scope of research expertise is unparalleled.

UMCES is also proud of its legacy in educating the next generation of environmental leaders. UMCES’ graduate students thrive in an innovation-rich, hands-on collaborative university and care deeply about the world around them. Passionate stewards of the environment, they go on to become leaders in government, industry, and education.

Service for a Brighter Future

UMCES is rooted in a century of service to the citizens of Maryland and beyond. Environmental science, guided by curiosity and a deep respect for the wonder of the natural world, will produce solutions, and the University of Maryland Center for Environmental Science will continue to lead the way.

UMCES gauges its century of prolific success not only by the number of scientific papers published and PhDs granted, but by the measure of hope its work can bring to a concerned public who see eroding shorelines or flooded roads, whose livelihoods depends on robust natural resources, or who miss seeing nesting turtles on a quickly eroding beach.

A Visionary Founder

Who was Reginald Truitt, founder of what would become UMCES? “IN THE SUMMER OF 1919, a brand new graduate student carried a borrowed microscope to a creek north of Solomons Island, Maryland, a knob of land near the meeting point of the Patuxent River and the Chesapeake Bay. In a cramped fisherman’s shack, he set up a makeshift laboratory, installed his microscope, and began studying oyster biology.”
