Charles W. Lipp is a Principal Consultant at Lake Innovation LLC with expertise in the areas of spray science and technology, reactive process mixing, and process scale-up. His diverse technical interests include cavitation and multiphase flows with application to chemical and plastics manufacturing processes. Until recently, he was a Technical Leader in the Engineering and Process Sciences: Fluid Mechanics and Mixing group of the Dow Chemical Company. His 35 year career at Dow included work on numerous process applications of spray and atomization technology and design of process injector systems. He led projects developing and scaling-up of manufacturing process technology which resulted in over 15 US patents. Chuck edited the Sprays article in the Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition and authored several peer-reviewed journal articles. He is an active member of AIChE and ILASS (Institute for Liquid Atomization and Spray Systems) Americas. He serves ILASS Americas organization as a member of the board of directors and edits the ILASS Americas newsletter. His BS degree in chemical engineering from Iowa State University was the foundation for his expertise development.

He also does volunteer work with Engineering Ministries International (eMI www.emiusa.org) on humanitarian projects. This work provides an opportunity for applying skills to help children and families around the world step out of poverty and into a world of hope. Working volunteer projects with eMI requires creative application of skills to match the local cultural and physical environment.  This work involved travel to Uganda, Bangladesh and Haiti.
