Areas of Expertise: Research and development of earthquake and fire resistant structural/construction systems using sustainable technologies. One construction system he has been developing uses straw bales in combination with reinforcing steel and concrete to create a structure that is economical and extremely earthquake-resistant for buildings up to five stories. As the main materials are readily everywhere, and since the construction is relatively low-tech it would be ideal for rebuilding in Iran. The construction type (SMS), so-called because it uses "spars" and "membranes" as the principal structural elements, has been used in the construction of several buildings in the U.S. Black plans to construct a pilot, three-story residential project in India in 2004.
