Martin HarmerMartin Harmer
Position:  Professor Emeritus
- Ph.D. Cermaics, Leeds University (England), 1980
- B.S. Ceramics, Leeds University (England), 1976
Research Areas:
- Ceramic Processing & Sintering
- Adavanced Electron Microscopy
- Grain Boundaries & Complexions
- Nanomaterials & Nanocomposites

Interests: Dr Martin P. Harmer is Professor Emeritus of Material Science and Engineering, Senior Research Scientist, and Director of the Lehigh Nano/Human Interfaces Presidential Research Initiative at Lehigh University. He studied ceramics at Leeds University in England from 1972 to 1980, where he graduated with a first class honors B.Sc. degree and a Ph.D. in ceramics, and he also received a D.Sc. degree from Leeds in 1995. He conducted his doctoral research on the rapid sintering of pure and doped alpha alumina under the supervision of Professor Sir Richard Brook. During his Ph.D. he spent one year on a graduate fellowship at the University of California at Berkeley, learning advanced techniques in transmission electron microscopy under the guidance of Professor Gareth Thomas. Dr. Harmer joined Lehigh University in 1980. He directed the Lehigh Center for Advanced Materials and Nanotechnology until 2015. From 2015- 17 he was Senior Faculty Advisor for Research Initiatives in the Rossin College of Engineering before taking up his current position of Director of the Lehigh Nano/Human Interfaces Presidential Research Initiative. He also currently Directs a 5-year $25M Cooperative Agreement research project with the Army Research Laboratory on “Lightweight High Entropy Alloy Discovery (LHEAD)”, in collaboration with The Ohio State University and Louisiana State University.

Dr. Harmer has supervised 65 Ph.D. students and 25 post-doctoral researchers and published ~350 papers. His research has focused on understanding the fundamental mechanisms of interfacial transport and microstructure development in inorganic materials. His work has led to fundamental discoveries about the nature of grain boundaries, including the breakthrough experimental discovery that grain boundaries exhibit phase-like behavior (called "grain boundary complexions"), which has provided new insight into long-standing mysteries in material science, such as the origin of abnormal grain growth in ceramics and the cause of grain boundary embrittlement in metal alloys. He has received numerous awards including the first Presidential Young Faculty Award from President Reagan, American Ceramic Society’s (ACerS) Distinguished Life Member Award, ACerS W. David Kingery Lifetime Achievement Award, ACerS Robert B. Sosman Lecture Award, and the Lehigh University Libsch Research Award and the Hillman Faculty Award..

Harmer is a United States Coast Guard Licensed Merchant Marine Officer and the Captain of a 39ft sportfishing vessel called the “Cheeky Monkey III”.
