ELIZA CLARK
Postdoctoral Researcher
Eliza is an NSF Postdoctoral Fellow in Biology, at Clemson University and the University of Colorado-Boulder. She received her PhD in Ecology from Colorado State University. She is interested in how organisms respond to global change through range shifts and rapid evolution. She has worked on study systems ranging from an insect biological control agent to agricultural sunflowers and a short-lived alpine plant. After work, you can find Eliza baking sweet treats, tending a tiny herb garden, and hiking to the top of tall places to get the view.

MARJORI DA SILVA
Graduate Student
Marjori is an incoming Brazilian Ph.D. student. She received her B.S. in Biological Sciences from the Federal University of Pernambuco (Brazil). She recently earned her M.S. in Biology from East Tennessee State University (ETSU), where her research focused on the impacts of heterospecific pollen in co-flowering communities in California serpentine seeps. At Clemson, she is interested in investigating reproductive community ecology, floral color ecology and evolution, and the effects of climate change on plant reproduction. In her free time, she enjoys hiking, spending time with friends, and eating ice cream.

MERCEDES SÁNCHEZ-CABRERA
Postdoctoral Researcher
Merce is a postdoc who joined the Koski Lab in 2025. She got her PhD at the University of Seville in Spain, where she studied the ecological and molecular causes of a shared flower color polymorphism in two Mediterranean species. She is interested in flower color evolution, plant-pollinator interactions, and flavonoid biosynthetic pathway genes. Merce’s postdoctoral work focuses on understanding the role of the background on flower color evolution by pollinator-mediated selection. In her free time, she enjoys pottery, hiking and a beer with friends!

SIERRA WILLIAMS
Graduate Student
Sierra is a master’s student in the Department of Biological Sciences. She graduated with her bachelor’s degree from Miami University in Ohio. In the past, she assisted with moth surveys, tick surveys, and forest and plant surveys. At Clemson, she is interested in pollinator-mediated floral evolution. Outside of work she enjoys hiking, knitting, and crocheting.

SOLIDAGO (SOL) ADAMS
Graduate Student
Sol is a PhD student in the Department of Biological Sciences. They hail from Maine where they recieved a BA in mathematics from the University of Southern Maine. In the past, they have done research on the physiological responses to hydroelectric power production in floodplain shrubs in the Grand Canyon, and the total dominating sets of (mathematical) trees. At Clemson, they are interested in investigating plant population genetics, flower color evolution, and self-incompatibility.

ZOË MITCHELL
Graduate Student
Zoë is an incoming Ph.D. student in the biological sciences department. She graduated from the University of Georgia in 2025 with her B.S in Biology. During her undergrad, she researched the effects of population density and isolation on the reproductive success of Helianthus porteri, a granite outcrop plant. At Clemson, she is interested in studying how climate change is directly impacting plant reproduction through a plant's ability to thermoregulate throughout its life. During her free time, Zoë likes to spend time with friends and explore new outdoor activities.
