My Teaching Philosophy

"I cannot teach anybody anything. I can only make them think." - Socrates  (c.470  BCE)

"You cannot teach a man anything. You can only help him find it within himself." - Galileo  (1564 - 1641 CE)

I see myself as a coach and a mentor focused on inspiring students to learn, pursue excellence, and capitalize on their innate strengths.

Four tenets of my teaching philosophy are:

  1. Help students understand the value proposition of learning the subject matter covered in a course
  2. Help students develop skills to devise innovative solutions to complex problems with consideration of global and societal contexts
  3. Make sure that students have a comprehensive understanding of the fundamental principles and that they develop competencies to apply the principles to solve seemingly intractable problems 
  4. Ensure that students learn to exercise highest levels of professional ethics and personal integrity in every aspect of engineering problem solving and interpersonal interactions

Simulation Driven Design

Simulation Driven Design is a promising approach to generate quality affordable aircraft configurations—a must for enhancing U.S. competitiveness in an increasingly globalized marketplace.  This approach is aimed at producing virtual prototypes which can faithfully represent the functional and operational characteristics of a real aircraft to be built.  The traditional design practices are inherently inefficient and expensive as they rely on extensive scale model testing to generate data for configuration design, and on developing physical prototypes to verify functional and operational characteristic. SDD derives its efficiencies and cost-effectiveness by combining the ever increasing power of computers with increasing sophistication of modeling and simulation methodologies based on high-fidelity physics-based computational methods. However, several challenges need to be overcome to realize the promise of SDD. For example, our inability to cost-effectively assess the credibility of computational solutions is a serious impediment. Developing physics-based models that are wellsuited for rapid-turnaround conceptual design studies in a multidisciplinary design, analysis and optimization environment is another.  Devising effective strategies to tackle such challenges is the primary focus of this research thrust. My Note that my emphasis has been on aerodynamic simulations using computational fluid dynamics (CFD). Some of the recent paper are listed below:
