Differential Equations, Numerical Analysis

Dr. Treinen received his Ph.D. from Wichita State University in 2004.  He has been working on fluid mechanics and fluid dynamics problems, primarily studying the equilibrium state of fluids.  The methods applied to these problems are somewhat diverse: techniques from partial and ordinary differential equations including free boundary regularity, numerical analysis, geometric measure theory, and the calculus of variations.
