David Arnosti is a Professor in the Department of Biochemistry and Molecular Biology. His research uses Drosophila models to study gene regulation in the context of development.

Prior to joining MSU, Dr. Arnosti received his Ph.D. from the University of California, Berkeley. He completed his postdoctoral training at the University of Zurich and the University of California San Diego. Dr. Arnosti is the Director of MSU’s Graduate Program in Biochemistry and Molecular Biology.


The Arnosti laboratory leverages the powerful genetics and molecular biology of Drosophila to test the importance of cis- and trans-acting regulators of transcription in a developmental setting. The lab’s fundamental research is critical for understanding the central regulatory mechanisms in biology, including in cancer, development, disease, and evolution. Current projects focus on mechanisms of regulation by retinoblastoma tumor suppressor proteins.
