About Me

Layek Abdel-Malek is Professor of Mechanical and Industrial Engineering (formerly Industrial and Manufacturing Engineering) and former Associate Dean of Engineering for Academic Affairs and Administration at New Jersey Institute of Technology. He earned a Ph.D. from New York University (f/k/a the Polytechnic University) in Operations Research and Systems Engineering, and a Master and Bachelor degrees in Mechanical Engineering from Cairo University in Egypt. Also, in 1970, he earned a diploma in Computer Science from the National Institute in Cairo. He has been teaching in the fields of Industrial Engineering and Operations Research in highly ranked universities including Columbia University, Rutgers University and the New Jersey Institute of Technology. Dr. Malek has consulted for conglomerates such as Schering Plough, Siemens, and AT&T, as well as small and medium size firms. He has been a Guest Professor in Germany, Sweden, Italy, and Thailand. He is the recipient of many Federal, state, and private grants in Industrial Engineering and related fields. He is a Fellow of the Institute of Industrial Engineers and serves on the editorial boards of journals in the area of Industrial Engineering and Operations Research. Dr. Malek has published significant number of articles in the top tier journals of his fields, in the areas of robotics, manufacturing, inventory control, solar energy, and supply chain management.

Research Interests

  • Effect of telemanufacturing on the competitiveness of SMES
  • Automated assembly systems
  • Tolerance analysis
  • Robotics

Current Research

One of Dr. Abdel-Malek projects addresses issues of quality manufacturability, while another involves an effort to provide innovative solutions for traditional electromechanical manufactures to improve their productivity. In addition, he is analyzing the effect of telecommuting on traffic patterns. Dr. Abdel-Malek also is examining the state of operations research in practice.
