I've been writing about engineering materials for more than 30 years, mostly steel and plastics. I covered the steel industry for the Pittsburgh Post-Gazette in the mid-1970s, and covered plastics technology as chief editor of Plastics World and as a senior editor at McGraw-Hill's Modern Plastics. I'm a member of the Society of Plastics Engineers, and have been responsible for materials and assembly coverage at Design News for the past four years. Drop me a line at firstname.lastname@example.org.
