August W. Bosse, Ph.D.

Brief Biography

I graduated with a B.S. in Physics, With Highest Honors, in June 2001 from the University of California, Davis. I then started my graduate work in physics, studying quantum cosmology with James Hartle at the University of California, Santa Barbara. After about one year as a quantum cosmologist, I shifted my research focus to theoretical polymer physics and equilibrium statistical mechanics. The bulk of my graduate research focused on theory and simulation of equilibrium polymer systems under the guidance of Glenn H. Fredrickson and Carlos J. García-Cervera. I graduated with a Ph.D. in Physics in December 2006. I started work at NIST in November 2006 as a Penn State Guest Researcher, and in the summer of 2007 I won an NRC/NIST Postdoctoral Research Associateship. I joined the NIST permanent staff in October 2008.

Research Interests

Polymer and soft matter theory, modeling, and simulation; statistical mechanics; computational science; block copolymers, equilibrium nanostructued materials; template-directed self assembly; field-based modeling; field-theoretic techniques; self-consistent field theory; continuum Monte Carlo methods; biomathematical modeling and systems biology; biophysics.

Research Overview: Field-Theoretic Polymer Simulations

The Polymers Division has an established effort in field-theoretic modeling and simulation of polymeric systems. Field-theoretic models can be applied to a wide range of equilibrium and nonequilibrium problems covering spatial and temporal scales spanning multiple orders of magnitude.

I am actively developing novel Ginzburg-Landau field theories, self-consistent field theories (SCFTs), and stochastic field theories. I routinely apply field-theoretic modeling frameworks to a wide range of polymer metrology problems; for example, detailed simulations using polymer field theories are an integral part of the Dimensional Metrology for Nanomanfacturing project.

Analytic solutions of field-theoretic polymer models are often elusive, due in large part to the mathematical sophistication of such models; accordingly, I have developed and/or implemented a wide array of numerical and computational tools for field-theoretic simulation of polymer systems, including accurate, stable, and extensible mean-field and stochastic techniques.
