Grady Koch emphasizes building things from LEGO that can be applied to practical use in science, engineering, or security.  He is the author of LEGO Optics:  Projects in Optical and Laser Science with LEGO, High-Tech LEGO: Projects in Science, Engineering, and Spycraft with Technic and Mindstorms EV3, and Secrets of Eli's LEGO Collection.  He also writes for and runs hightechlego.com, which features various LEGO technology projects. His day job since 1987 has been as a research engineer with NASA Langley Research Center. There he works with technology for remote sensing atmospheric phenomena.  He holds a PhD in Electrical Engineering.  And he holds three patents in the field of wind measurements with lidar.
