Garrett G. Gross, PhD, is a research associate in the Department of Molecular Biology at the University of Southern California (USC). He received a BS in biochemistry and molecular biology from the University of California, Davis in 2003, where he worked for Dr. Alan B. Balch and Dr. Paul J. Hagerman. After completing his undergraduate education, he continued his training in the laboratory of Dr. Ming Guo at the University of California, Los Angeles, where he used pre-clinical models to study Alzheimer's disease and Parkinson's disease. In 2009, he graduated with a PhD in neuroscience and joined the laboratories of Dr. Richard W. Roberts and Dr. Don B. Arnold at USC as a post-doctoral fellow. With their guidance, he applies a directed evolution method pioneered by Dr. Roberts, known as mRNA display, to create novel therapeutics and antibody-like probes (immune system protein tags) expressed inside cells.
