I am an accomplished, versatile writer with particular expertise in science and technology. With hundreds of feature articles, weekly columns, op-eds, and technical and specialist works published over the past fourteen years, I combine ability and passion for writing to produce stimulating, persuasive and informative copy for any situation.
