Research Expertise and Interests

  • Research in manufacture and metrology of precision and ultra-precision surfaces for optics and other precision applications
  • Research into process-automation and robotics, as applied to iterative rather than deterministic processes; leading towards the ultimate vision of a fully-autonomous manufacturing cell
  • Research into optical instrumentation techniques in general and astronomical instrumentation in particular
