Dr. Gearing has substantial experience with a wide variety of technologies, including materials science, mechanics and dynamics of materials, cancer therapy, semiconductor and hard disk design and manufacturing, microprocessor technology, wireless communications, and networking equipment and architecture. He also counsels clients on the implementation of new technologies such as blockchain and distributed ledgers, and the development of innovative products such as virtual currencies and blockchain-based assets.

Before law school, Dr. Gearing earned a Doctorate of Philosophy from the Massachusetts Institute of Technology, where his research focused on the mechanics and dynamics of materials with an emphasis on fracture of polymers, as well as mechanical testing at the micro- and nano-scales. During law school at U.C. Berkeley School of Law, Dr. Gearing was a member of the Berkeley Technology Law Journal and a fellow of the Berkeley Center for Law & Technology.

Ltd. v. ImClone Systems Inc. and Aventis Pharmaceuticals Inc. The Federal Lawyer, 55(2), 51-55 (2008) (Groombridge, N. and Gearing, B.).
