Who we are

Jen Klug, Professor of Biology

I grew up swimming, sailing and fishing in lakes in my home state of Michigan and have always been interested in what lies beneath the surface. I received my B.S. in Geology at Indiana University and M.S. and Ph.D. in Zoology at the University of Wisconsin. My research focuses on how aquatic ecosystems respond to environmental change. I am also interested in science communication and am working on improving my skills in that area! At Fairfield, I teach Freshwater Ecology, Biology of Food, Ecology of the North Atlantic Coast, and General Biology. If you are a Fairfield undergraduate student interested in joining the lab, come find me in BNW 209 or email me at jklug@fairfield.edu.

Katie Biardi, Undergraduate Research Student

I am a senior Biology and Environmental Studies major, and am currently looking to pursue a graduate degree in Ecology and Evolutionary Biology. Within the lab, I analyze and create the annual reports for CLEO, and I am also writing a QAPP for the CLEO training procedures. I am also interested in comparing citizen science data collected by CLEO volunteers to water quality data collected by the buoy in order to find out how well the buoy can measure algal blooms. I can be reached at katherine.biardi@student.fairfield.edu

Teresa Sauer, Undergraduate Research Student

I am a Junior Biology major with minors in Environmental Studies as well as Peace & Justice Studies. I have always been interested in ecological research because it allows us to understand the complexity of the world around us and the effects which humans can have on it. I am currently developing my honors thesis in the lab by analyzing how various factors affect indicators of water quality in Lake Lillinonah. I am also interested in the development of outreach products which engage with the public and begin scientific conversations in which everyone can participate. I can be reached at teresa.sauer@student.fairfield.edu.

Our Projects

We collaborate with Friends of the Lake, a local non-profit organization, on two water quality monitoring projects.

CLEO at Lillinonah

The Citizen-Led Environmental Observatory (CLEO) is a volunteer water quality monitoring project. CLEO has been running at Lillinonah since 2006 and we hope to expand to other lakes in Connecticut. Learn more about CLEO below (webpage made by Katie!).

High-frequency monitoring with automated sensors (aka the buoy project)

The Friends of the Lake research buoy on Lake Lillinonah is outfitted with sensors that measure water temperature throughout the water column, dissolved oxygen at surface and bottom, pH, conductivity, and algal pigment fluorescence. The lake, its data, and its people are part of the Global Lakes Ecological Observatory Network (GLEON). We use the data collected by the buoy to address questions of both local and global significance. See below for recent projects.


We are proud to be part of NEGLEON! NEGLEON is a group of lake labs in Northeastern North America affiliated with the Global Lakes Ecological Observatory Network (GLEON). NEGLEON members collaborate on projects that engage undergraduate students in team science. For more information, see #NEGLEON on twitter or check out our webpage (made by Teresa!) below.
