From the show bio:
Bryan E. Laubscher received his Ph.D. in physics in 1994 from the University of New Mexico with a concentration in astrophysics. Bryan has just returned to Los Alamos National Laboratory from a year-long Entrepreneurial Leave to Seattle. There he started a company to develop the strongest materials ever created. These materials are based upon carbon nanotubes – the strongest structures known in nature and the first material identified with sufficient strength-to-weight properties to build a space elevator. At LANL he is a project leader and has worked in various capacities for 16 years. His past projects include LANL’s portion of the Sloan Digital Sky Survey , Magdalena Ridge Observatory and a project developing concepts and technologies for space situational awareness. Over the years Bryan has participated in research in astronomy, lidar, non-linear optics, space mission design, space-borne instrumentation design and construction, spacecraft design, novel electromagnetic detection concepts and technologies, detector/receiver system development, spectrometer development, interferometry and participated in many field experiments. Bryan led space elevator development at LANL until going on entrepreneurial leave in late 2005.
I should note that Bryan is also a founding member of the International Space Elevator Consortium (ISEC) and is on the ISEC Board of Directors as well as being head of the ISEC Technical Pillar Committee.
