Previous research
positions
Post-doctoral position:
1997-2000, Research Fellow, Centre for Water Research, University of
Western Australia.
Developed, tested and validated numerical model for lakes and estuaries
that combines some of the latest advances in conservative monotonic
transport schemes with a new mixed-layer approach to computing the
vertical mixing.
Graduate research: 1991-1997, Research Asst., Environmental Fluid
Mechanics Laboratory, Stanford University.
Developed a new approach to model the evolution of a free surface in a
curvilinear coordinate system for the full Navier-Stokes equations.
Used this approach with a LES scheme to model the wave-current
interactions of nonlinear waves moving over a turbulent open-channel
flow.
Industry research: 1989-1991, Senior Engineer, M. Rosenblatt & Son,
Naval Architects and Marine Engineers.
Conducted laboratory experiment to analyze the orifice flow resistance
of a two-layer oil/water system. The experiment was designed to
demonstrate the problems of seawater retention in compensated fuel
tanks at high fueling rates. Funded by NAVSEA Code 56Y3, Program
Manager V.A. Coppola.
Recent consulting projects
City of Austin, Department of
Water and Wastewater Management, review of Pedernales River and Lake
Travis modeling in Environmental Assessment of Longhorn Pipeline
project, 2001-2002.
Texas Water Development Board, Analysis of hydraulic modeling for
instream flow requirements, 2002.
Industry experience
Seven years in industry as a
marine engineer in a variety of positions, including ship overhaul,
offshore oil drilling platform operation, and as a consultant on fluids
systems in U.S. Navy ship construction. Projects of particular note
included design of ballast tanks on LHD amphibious vessels for improved
performance, and analysis of problems associated with two-fluid flows
in seawater compensated fuel tanks on DDG 51 class destroyers.
