Xiaochu Ma is a Technology Specialist, Patent Agent, in the Boston office of Fish & Richardson. Her practice focuses on U.S. and foreign patent drafting and prosecution in the areas of life sciences, including microbiology, virology, biochemistry, molecular biology, and biophysics. Specifically, Xiaochu has experience in technical areas such as antibody development and therapeutics, vaccine development, gene editing technologies, RNA interference, biomaterials, stem cell technologies, anti-cancer therapeutics, and drug development.
Xiaochu conducted her Ph.D. research at Yale University. Her research focused on the mechanism of HIV-1 infection. Using a single molecule Fluorescence Resonance Energy Transfer (smFRET) technique, her work revealed a critical intermediate step during the virus’ entry into host cells and identified several conformational epitopes for AIDS vaccine design. While at graduate school, Xiaochu was also a technology transfer intern at the Office of Cooperative Research of Yale University, where she gained experience in pre-drafting patentability analysis and marketing and commercialization of innovations.
