Kendra Autumn, Ph.D.
SRI FellowKendra Autumn, Ph.D.
SRI FellowKendra completed her BA in Biology at Willamette University and her PhD in Biology at the University of Utah. She is broadly interested in the evolution of symbioses, particularly in fungi. Her graduate work focused on using phylogenetics and genomics to investigate the evolution of parasitism of fungi by other fungi (mycoparasitism) in the agriculturally and industrially important order Hypocreales. She is currently working to characterize undiscovered diversity in the mycoparasitic genus Hypomyces and exploring poorly understood associations between Hypomyces molds and their mushroom hosts. Her mentorship style welcomes students to ask questions and make mistakes as they gain experience and confidence in a laboratory setting. She is invested in public science communication and prioritizes student involvement in outreach projects.
kendra.autumn@utah.eduMikhael Semaan, Ph.D.
SRI FellowMikhael Semaan, Ph.D.
SRI FellowMikhael received twin BSes in Electrical Engineering and Physics from California State University, Long Beach, before continuing to the University of California, Davis for his Physics PhD. While at Davis, he taught active learning-based courses geared towards bioscience majors and cultivated a passion for scientific communication between disciplines. His research centers on how pattern and structure emerge in “complex systems:” how do we discover nature's patterns? How do we recognize a forest's structure as intricate, but a coin flip's as simple? Tackling these questions involves a combination of techniques from physics, mathematics, and computer science—applied in such seemingly unrelated areas as finance and cardiology! As an SRI Fellow, Mikhael is most excited to equip students not just with these tools but with the skills to build new ones, so that they might carry them across disciplinary boundaries throughout their chosen careers.
m.t.semaan@utah.edu Rodolfo Probst, Ph.D.
SRI FellowRodolfo Probst, Ph.D.
SRI FellowRodolfo received his B.Sc. in Biology at the State University of São Paulo and an M.Sc. in Systematics, Taxonomy, and Biodiversity at the University of São Paulo, both in Brazil. He recently obtained his Ph.D. at the University of Utah (Ecology, Evolutionary and Organismal Biology), where he investigated the evolution of ant-plant mutualistic interactions while working in the lab of Jack Longino. His research uses genomic tools, taxonomy, and natural history to understand ant-plant symbioses. He is led by his interest in insect evolution and his passion for tropical fieldwork, teaching the public about bugs and conservation, and exploring the outdoors. When not at the lab or collecting ants, he likes going road biking and hiking around Utah, cooking, and writing poetry.

austin.m.green@utah.eduKasey Cole, Ph.D.
SRI FellowKasey Cole, Ph.D.
SRI FellowKasey recently received a Ph.D. in Anthropology, with an emphasis in zooarchaeology (the study of animal bones from archaeological sites) and paleoecology, at the University of Utah. As a Postdoctoral Fellow with the Science Research Initiative, she is studying the fossil animal remains recovered from Utah’s high-elevation cave deposits to establish what animal communities looked like prior to anthropogenic climate change. Using this data, her work compares these past records with recent zoological survey data to evaluate whether ongoing climate change has contributed to range shifts or local extinctions, as has been predicted for the region’s montane mammals. Her research is interdisciplinary, incorporating theory and methods from Anthropology, Ecology, Geology, and Climate and Environmental Sciences. As a mentor, she strives to build a collaborative research environment aimed at equipping students with transferable skills and experience with science communication.
kasey.cole@utah.eduAndrea Halling, Ph.D.
SRI FellowAndrea Halling, Ph.D.
SRI FellowAndrea completed dual B.Sc. degrees in Physics and Biology with an education emphasis from Utah State University. She taught high school physics for two years before pursuing a Ph.D. in Geobiology from the University of Colorado, Boulder. Her research focused on the origin and evolution of multicellular life, using experimental evolution to better understand the interaction between single cells and their physical environment 700 million years ago, and how the cold viscous oceans during that time might have selected for simple life to become more complex. As an SRI Fellow, she continues to study the interplay between life and the physical environment by using the Great Salt Lake to understand how planktonic life adapts to the changing ecosystem today. She is passionate about science education and outreach, and in her free time loves to climb mountains, ski, and cuddle her cat Penelope.
