The Buchan lab studies how cells regulate gene expression at the level of cytoplasmic messenger RNA (mRNA), the templates of protein synthesis. Areas of particular interest include mRNA-protein bodies called stress granules and P-bodies, which regulate mRNA function, cell signaling, and are implicated in the pathology of viral replication, various cancers and neurodegenerative diseases such as ALS.

The Horton lab uses biophysical, biochemical, and molecular biology to study protein-DNA interactions and filament formation by enzymes. Current projects include the investigation of mechanisms of disease caused by the Human Parvovirus B19, and advantages of filament formation by enzymes such as the sequence specific DNA endonuclease SgrAI, and the important metabolic enzyme PFK.

Professor Betül Kaçar is an astrobiologist exploring the origins of life on Earth and finding life on other planets in the Universe. She is an Assistant Professor at the University of Arizona in the Departments of Molecular & Cellular Biology as well as Astronomy and the Lunar & Planetary Laboratories. Prior to Arizona, she was a NASA Astrobiology Postdoctoral Fellow at Harvard University where she developed molecular systems to bring ancient DNA sequences into the laboratory for physical, chemical and biological characterization. Her research is supported by NASA Exobiology and Evolutionary Biology Programs, NASA Astrobiology Program, the John Templeton Foundation, the National Science Foundation, Harvard University Origins Initiative as well as the University of Arizona Foundation. Betul is one of the Principal Investigators of the NASA Astrobiology Institute Reliving the Past node, is an associate member of the NASA Nexus for Exoplanet System Science designed to foster interdisciplinary collaboration in the search for life on exoplanets, and currently holds an Adjunct Professor position at Earth-Life Science Institute in Tokyo, Japan, which is dedicated to understanding the origins of life. She was named a Scialog Fellow of the Heising-Simons Foundation and Kavli Foundation to study the Biosignatures and Life in the Universe in 2020, a NASA Early Career Fellow in 2019, and a Way Cool Scientist by the Science Club for Girls in 2017. Her research has gained national and international attention, and has been featured by CNN, BBC, NOVA Science, Discover Magazine, NPR Science Friday and Scientific American.

The Sutphin Lab studies the molecular basis of aging. Individual age is the primary risk factor for the majority of the top causes of death in the United States and other developed nations. As our population grows older, aging is increasingly a central problem for both individual quality of life and the economics of societal health. Understanding the molecular architecture that drives aging will reveal key intervention points to extend healthy human lifespan, simultaneously delay onset of multiple categories of age-associated disease, and develop targeted treatments for specific pathologies. We use a combination of systems biology, comparative genetics, and molecular physiology to identify new genetic and environmental factors in aging and characterize their molecular role in age-associated disease.
