Dr. Nazim Nathoo

Advisor


Dr. Nazim S. Nathoo is an Independent Consultant retiring in 2009 as Senior Principal Consultant from the Westhollow Research Center at Shell Global Solutions (US) Inc., where he:

  • Defined/participated in/oversaw the development of the software and field implementation of the Turbomachinery Thermodynamic Performance Evaluation technology – still in use as a standard approach in Shell US.
  • Oversaw the development of the suite of Turbomachinery Rotordynamic Analysis simulation programs.
  • Developed and patented innovative fabrication techniques for Shell’s ventures in supporting composites and diaper manufacture.
  • Introduced sophisticated high-fidelity Dynamic Simulation technology to understand/resolve transient behavior of mechanical and process (lube/seal oil, vent gas recovery, and utility – steam, air, hydrogen, etc.) systems.
  • Introduced and developed Reliability Modeling technology for complex integrated networks and individual operating assets. Both these technologies represent significant growth areas that have been recognized as high value-added ones to Shell businesses and as Top Notch Technologies.

Dr. Nathoo was a faculty member at the University of Houston, Department of Mechanical Engineering and an Instructor at the University of Texas at Austin, Department of Mechanical Engineering.

Dr. Nathoo received his Ph.D. (Mechanical Engineering) from The University of Texas at Austin, Austin, Texas and his B.S./M.S. (Mechanical & Aerospace Engineering) from the Illinois Institute of Technology, Chicago, Illinois.
