Welcome to the Department of Industrial and Systems Enginering (ISE) at Lehigh University!

Industrial and systems engineering is a fantastic branch of engineering which deals with the optimization of complex processes, systems, networks, investments or organizations.  We develop, improve, and implement integrated systems and our goals may involve cost or profit, material, productivity, energy, time or other key resources.

Our field is naturally multidisciplinary and we learn and master the fundamental principles of various disciplines such as modern manufacturing and automation, computing and information systems, algorithms and simulation, data science, decision and game theories, statistics and queuing theory, mathematical optimization, and operations research and management sciences (from supply chain, facility layout, and transportation to healthcare and finance). Our field is however also interdisciplinary in the sense that ISE is indeed a new synthesis! We are in a unique position to excel in a world where resources are scarce, competition is ubiquitous, and risk is a permanent concern.

Lehigh’s ISE Department has a worldwide reputation and a long tradition in industrial engineering. A department that has been constantly adapting to the high tech & data revolution of our current days. A department that has a small student-to-faculty ratio, and provides an inspiring environment to study and discover.

Our BS and MS programs are among the very best in the country. Here we form professionals with a solid knowledge and understanding of the industry needs, but who are simultaneously problem solvers and critical thinkers. A great number of our alumni have become leaders in their fields of operation.

We do cutting-edge research in Mathematical Optimization, Data Science and Machine Learning, Energy and Service Systems, and High Performance Computing. Our PhD program is vibrant and highly selective and has been providing financial support for incoming students and offering great job opportunities to those who have completed it, both in academia and in the industry.

I invite you to visit us on campus or browse our webpage where you can find information about our degrees, faculty, dedicated programs and centers, computing resources, and laboratories.
