Dilhan M. Kalyon is a Turkish-American chemical engineer and Institute Professor of Chemical Engineering and Materials Science at Stevens Institute of Technology in Hoboken, New Jersey. He is the founding director of the Highly Filled Materials Institute (HfMI) at Stevens, established in 1989, which conducts sponsored research on the processing and characterization of complex fluids, polymeric suspensions, and gels for industrial and government partners. His research is focused on the rheology of viscoplastic fluids, highly filled suspensions, energetic materials processing, and biomedical materials.
Kalyon attended Talas American Middle School and graduated from Tarsus American College in 1971. He earned a Bachelor of Engineering in Chemical Engineering from Middle East Technical University (METU) in Ankara, followed by a Master of Engineering (1977) and a Doctor of Philosophy (1980) in Chemical Engineering from McGill University in Montreal, supported by a merit scholarship.
Kalyon joined Stevens Institute of Technology in 1980 and rose through faculty ranks to the title of Institute Professor in 1999, the institution's highest academic distinction. He holds a joint affiliate appointment in the Department of Biomedical Engineering. In 2019 he was appointed Interim Vice Provost for Research, Innovation and Entrepreneurship at Stevens.
Kalyon serves on the editorial board of the Journal of Tissue Science and Engineering.
Kalyon's scholarship centres on the mechanics and processing of viscoplastic fluids, materials that remain rigid below a critical yield stress and flow above it. His group has developed novel rheometers, mathematical models for wall-slipping concentrated suspensions, the Mooney-Kalyon Plot and continuous twin-screw extrusion methods with applications across several domains:
