Saad Khan is the INVISTA Professor & Director of Graduate Program in the Department of Chemical & Biomolecular Engineering at North Carolina State University. Research in the Khan Research Group focuses on soft-solids: gels, colloids and associative networks. Of particular interest is the relationship between material microstructure, chemistry, and macroscopic properties. The use of rheology with other techniques provides a powerful and unique combination to understand and describe the macroscopic behavior of structured systems in terms of their underlying chemistry and/or microstructure. This has resulted in focusing in many different areas over the years, including enzymatic modification of water-soluble polymer and gels, photo crosslinked polymers, self-assembled nanoparticulate silica and nanodiamond gels, associative polymer interactions with surfactants and cyclodextrins leading to applications in coatings, drug delivery, energy storage device and hydraulic fracturing, to name a few. More recently the group has made forays to other areas such as crop protection for enhanced food security as well as examining multifunctional systems composed of nanofibrous structures and aerogels. The group has had over 50 PhD (including current) students resulting in over 200 publications (h index 54 ws) and over 16 patents. Khan received his bachelor’s degree from Princeton University and his PhD from MIT, both in chemical engineering.
