Research Interests

I am interested in understanding fundamental fluid dynamics problems and their applications in civil and environmental engineering. To this end, my approach to research involves mainly numerical flow modeling in combination with theoretical and experimental methods, with an emphasis on analysis of fundamental fluid flow processes.

My principal research interests are environmental fluid mechanics, hydraulics, geophysical fluid dynamics, wind engineering and hydrology. My recent research work has focused on aspects such as breaking internal waves, turbulent mixing in stably stratified flows, sediment transport and water quality modeling. I completed my PhD at Stanford University from the Environmental Fluid Mechanics Laboratory in the Department of Civil and Environmental Engineering. My dissertation focused on breaking internal waves using numerical simulations with an emphasis on understanding the energy partitioning and dynamics due to wave breaking.

Teaching Experience

• Instructor for Fluid Turbulence and Modeling (developed and taught by me)- (CIVE604) in the Department of Civil and Environmental Engineering (Spring Semester 2011). This is a new advanced graduate course focuses on turbulent flows. Turbulence is a ubiquitous phenomenon in fluid flows (both natural and engineered) e.g. in rivers, estuaries, oceans and the atmosphere. Over the course of the semester, both the theory of turbulent flows and on how to model such flows will be discussed. This course will expose the student through a lecture and discussion style format to the state of the art in turbulence modeling and discuss cutting edge research findings in the classroom. Successful students will be able to explain the formulation and limitations of turbulence models in the context of the closure problem; Identify, formulate and apply appropriate turbulence models in CFD problems; and have a clear awareness of approximations and limitations of different categories of turbulence models. They will be able to demonstrate a basic understanding of turbulence modeling for hydraulic, environmental and wind engineering flows

• Instructor for Computational Fluid Dynamics for Civil Engineers - (CIVE607 - used to be CIVE581A2) in the Department of Civil and Environmental Engineering at Colorado State University (Spring Semesters 2009, 2010, 2011). This second graduate course (developed and taught by me) focuses on providing an in-depth coverage of computational solutions of hydraulic and wind engineering problems. Course topics include: Introduction to turbulence models and to basic concepts of numerical simulation and computer modeling of turbulent flows in the environment. Application of numerical models in hydraulics, environmental fluid mechanics and wind engineering.

• Instructor for Models and Computational Methods in Civil Engineering (developed and taught by me)- (CIVE580A3) in the Department of Civil and Environmental Engineering (Fall Semester 2010). This is a new first graduate course for civil and environmental engineers on mathematical modeling and computational techniques with an emphasis on fundamentals of numerical methods for the solution of differential equations (both ordinary and partial) encountered in all the different disciplines in civil and environmental engineering. Course topics include: Interpolation, curve fitting, linear systems, numerical differentiation, numerical integration, numerical solution of ordinary differential equations (both initial-value and boundary-value problems) and numerical solution of partial differential equations (parabolic, hyperbolic and elliptic PDEs). Students will learn to write programs using MATLAB, a popular engineering software package. This course is aimed at first year graduate students as well as senior undergraduate students wishing to learn about modeling and numerical solutions of engineering problems. This course will be a prerequisite for a follow-on graduate course in computational fluid dynamics (CIVE607) in civil engineering.

• Instructor for Fluid Mechanics - (CIVE300) in the Department of Civil and Environmental Engineering at Colorado State University (Spring Semesters 2009, 2010, 2011). This is an introductory course in fluid mechanics/hydraulics for Civil Engineers. From water supply to stormwater drainage and flood routing to design of hydraulic structures to pollutant transport, a thorough understanding of civil and environmental engineering systems requires an excellent working knowledge of the fundamentals of fluid mechanics. Course topics include: Fluid properties, hydrostatics, fluid kinematics and governing principles of fluid motion, Reynolda transport theorem and conservation laws, dimensional analysis and similitude, viscous flow in ducts and conduits, flow over immmersed bodies and open channel flow.

• Instructor for Engineering Mechanics - Dynamics at Colorado State University (CIVE261, Spring and Fall semesters 2008): This is a class dedicated to understanding a branch of Applied Mechanics often referred to as Dynamics. Topics covered include particle and rigid-body kinematics and kinetics.

• Teaching Assistant for Rivers, Streams, and Canals at Stanford University (CEE161/CEE264, Fall 2005, course taught by Dr Derek Fong): This is a class dedicated to understanding a branch of Fluid Mechanics often referred to as Open Channel Flows/Hydraulics. The course covers uniform flow, gradually varied flow and unsteady flow. This class was the given the best rating in the faculty of engineering for this particular quarter.

• Teaching Assistant for Modeling Environmental Flows at Stanford University (CEE262C, Spring 2004, course taught by Professor Fringer): Introduction to turbulence models and to basic concepts of numerical simulation and computermodeling of turbulent flows in the environment. Application of models to estuary and lake/reservoir simulations. Use of computer models for estuarine and lake/reservoir dynamics and water quality. The effects of stratification. (this class was also taught via optical fibre link to NTU (Singapore) MS students).

• Worked as a Lecturer in the Department of Civil Engineering at the University of Natal from January 2001 to August 2002. I formally lectured Structural Analysis (second year BS undergraduate course) and Fluid Mechanics (third year BS undergraduate course) to civil engineering students. Received outstanding student evaluations and best lecturer rating in the department.
