Justin E. Culbertson, Ph.D.

Associate| Phoenix

Justin Culbertson is an associate at our Phoenix office. He practices intellectual property law, with emphasis on patent portfolio growth, strategy, and management in the chemistry, pharmaceutical, and biotechnology fields.

While in law school at the University of Illinois, Justin worked as an organic chemistry professor at Parkland College and participated in a mortgage foreclosure clinic helping families retain their homes in foreclosure.

Prior to law school, Justin earned his Ph.D. in Chemistry from the University of California, Davis. His interdisciplinary graduate research involved the design and mechanistic evaluation of small molecule inhibitors of the chorismate-utilizing enzymes. Justin's studies helped him gain a deep understanding of small molecule synthesis, purification techniques, protein engineering and design, x-ray crystallography, and molecular biology.

Between graduate school and completion of his undergraduate studies, Justin spent a summer working at GlaxoSmithKline synthesizing vaccine adjuvants.
