Joachim Grenestedt is professor of mechanical engineering and director of Lehigh's Composites Lab. His expertise is in designing, manufacturing and operating advanced vehicles. Present research focuses on:

• High-speed boats, slamming testing, new structural concepts (steel-composite hybrids), and new vehicle concepts for drastically improved ride (Suspension boats)
• Unmanned aircraft for high altitude dynamic soaring,
• Unmanned boats for characterizing waves, as well as for harbor patrol and riverine operations
• Unmanned aircraft that can be launched from a cannon

Since joining Lehigh's faculty in 2000 he has used composites in the development of innovative designs, from ship hulls to skis to record-breaking streamliners.
