A staff scientist in LLNL’s Energetic Materials Center, Dr. Grapes currently leads process development for the additive manufacturing of energetic materials.  In this role, he has been instrumental to the majority of LLNL’s advancements in multimaterial additive manufacturing of energetics since joining the lab as a postdoc in 2016.  Research interests include the development and integration of new diagnostic tools to collect compositional and structural information about a part during printing, addressing the challenges associated with process scaleup, and code development to enhance the repeatability and usability of LLNL’s additive manufacturing equipment.  In addition, development of new staff and planning for a large-scale AM facility at Site 300 currently occupy a large fraction of his time.

Outside of work, Mike is an avid ultimate frisbee player and enjoys spending weekends playing with his two young sons.
