Bailey Millis, Kelsey Gorgei, Emily Szydlo, Elizabeth Parkerson, Milad Zameeri, and RoseMina Notch will participate in an immersive, hands-on Summer research program in Geroscience research labs at UConn and UConn Health.
The UConn Undergraduate Education in Aging and Geroscience Research Program is an education and research initiative sponsored by the National Institute on Aging. (NIA) The program integrates coursework, research, and outreach activities.
The $15 million NSF-funded initiative, EvoME Institute, seeks to generate new biological insights and help scientists forecast the future effects of climate change in Arctic ecosystems and beyond. Read the story in UConn Today
The Santiago-Martinez lab uses modern approaches to investigate ancient things.

Cellular life on Earth can be classified into one of three domains: Eukarya (Eukaryota), Bacteria, and Archaea.
Dr. Geo Santiago-Martínez, Principal Investigator at the UConn Microbial Ecophysiology Laboratory.
Though most of us are familiar with species that fall into the Eukaryota and Bacteria domains, those belonging to the Archaea domain are often ignored despite being found all around us. From the Greek word meaning “ancient things,” archaea are found in a variety of harsh environments like boiling-hot geysers and salt lakes, but they can also be found in the soil and the digestive tracts of several animals, including humans. The Archaea domain was established in the late 1970s after scientists began using genetic sequence (rather than physical characteristics) to classify organisms and reveal how closely they are related[1]. The significant difference between the genetic sequences of microbes that physiologically appeared to be very similar to one another led scientists to establish the Archaea domain to separate these species from Bacteria and Eukaryota.
In science, there are often times when art and data are indistinguishable. To showcase the beauty of the Molecular and Cell Biology (MCB) Department's research and the creativity of its members, we are proud to introduce the first Picturing MCB Image Competition! Anyone associated with the MCB Department may submit an unlimited number of entries for consideration.
The All-Biology Colloquium was held with great success on Friday, April 26, 2024. The Colloquium showcased undergraduate research occurring in the three Biology departments at UConn. Award winners were celebrated at a reception prior to the graduation ceremonies on May 5. Congratulations to these exceptional students!

Paxton Tomko ’24is a molecular and cell biology major and her faculty mentor is Assistant Professor of Molecular and Cell Biology/Microbiology Geo Santiago-Martínez. In the fall, she will be starting a master’s in oceanography at UConn Avery Point, working with Professor of Marine Sciences Pieter Visscher. Tomko’s research interests are in geobiology and astrobiology and is interested in stromatolites as biosignatures and the role that methanogens play in microbial mats.
2024 Summer Undergraduate Research Fund (SURF) Awards have been announced. Of the 50 recipients, 13 are Molecular and Cell Biology majors! These students were selected from a strong group of applicants representing diverse areas of academic inquiry.
