Primary fields include chemistry, pharmaceuticals and chemical related documentation. In addition, I have translated numerous works on computer hardware and software, electronics, lasers, semiconductors, microdevices, micromachines, robotics, automotive technology, home appliances, environmental technology, microbiology, biotechnology, biochemistry, heavy equipment, power production systems, space technology, aviation, nuclear technology, superconductors, telecommunications, particle accelerators, medical equipment, pharmaceuticals, etc., for various agencies and direct clients, as well as lengthy government documents, pamphlets, papers, manuals, letters, registries, game software content and web pages, technical and general.

Patent translation: approximately 60% of the translations I currently do are patent related. I have experience over a broad range of patent material including most of the fields above. Patent areas include chemistry, pharmaceuticals, medical equipment, electronics (semiconductors, electro-optical materials, lasers, communications equipment, etc.), biotechnology, biochemistry, material science, power, home appliances, biology, microbiology, energy and environmental materials, micromachines, robotics and telecommunications. I have also done a substantial amount of work for law firms on technical documentation related to litigation, including in-house work at firms.

Patent related translation: documentation related to patents, such as prior art documents, office actions, correspondence among attorneys, inventors and other parties involved in the filing, research and litigation processes for patents.

Academic and commercial technical translation: I also translate research and commercial documents in the fields above.
