Ph.D. Program

The doctoral Mechanical and Energy Engineering program at the University of North Texas offers you a groundbreaking opportunity to learn fundamental and applied knowledge compatible with mechanical engineering, renewable energy, energy modeling, manufacturing and fossil fuels.

Our Doctor of Philosophy degree is the first of its kind in Texas. The innovative curriculum allows you to study and conduct research with world-class faculty members. This collaboration can lead to being published in professional journals, a validation of your hard work and strong research.

In addition, you’ll work with faculty members to develop both a broad and in-depth knowledge for solving energy problems. You’ll explore topics such as:

  • Fundamentals of energy
  • Thermal energy and fluids
  • Solid mechanics and controls
  • Renewable and alternative clean energy
  • Energy efficient products and structures
  • Bio-based green and sustainable products
  • Energy efficient intelligent vehicles

Our faculty members have been honored by the American Society of Mechanical Engineers and the American Society of Heating, Refrigerating and Air-Conditioning Engineers, among others. Their research areas include environmental sustainability, materials and manufacturing, and oil and gas.

The University provides several services exclusively to graduate students. The Graduate Student Writing Support office can help you with writing, and the Center for Interdisciplinary Research offers assistance with statistical research.

A Dissertation Boot Camp and other specialized workshops are available through the Toulouse Graduate School®. Many of the workshops are available online for your convenience.
