Joan T. Muellerleile is a Independent Consultant. Colleagues describe her as "I worked with Joan on several projects while she was in Battelle's Advanced Materials group. She's one heck of a Chem E, extremely knowledgeable of composite materials and the constituents used in those composites. Her reseach methods are thorough and well-thought through. Joan gave valuable advice to a number of composite pressure vessel manufacturers, in terms of the manufacturing methods, quality control, and product testing. I enjoy working with Joan, and I hope to have the opportunity again in the near future." and "Dr. Muellerleile is an exceptional scientist and researcher. She managed numerous technical research efforts for me in support of our Clients. When I needed assistance in Materials Science she was always my first choice. Dr. Muellerleile can be relied upon for her deep technical understanding and intellectual honesty. Until she has satisfied herself that a proposed solution, to a difficult technical problem, is absolutely correct she will not provide her endorsement. During her research she was pressured to provide her approval before she was convinced that we had found the correct solution. Dr. Muellerleile withheld her approval until she was convinced that we had in fact found the right answer. She is a gifted scientist and an incredible asset to any research and developmental team. Dr. Muellerleile has a broad understanding of materials science and provides the critical thinking required for a successful endeavor."
