More or less the first research I did regarding suspensions was my Ph.D. thesis, submitted to the mathematics department of MIT in July 2003. It is a big file though, due to the number of pictures.

Sedimentation in a stratifed ambient


My first paper was written in collaboration with John Bush and Bev Thurber and is concerned with particle clouds. My contribution was to model the flow of a particle cloud and simulate numerically its progression. This paper was published in the Journal of Fluid Mechanics in August 2003, vol 489, pp 29-54.

Particle clouds in homogeneous and stratified environments


My next paper was written in collaboration with Tom Peacock and John Bush and is concerned with the Boycott effect in a stratified ambient. It was published in the Journal of Fluid Mechanics in April 2005, vol 529, pp 33-49.

The Stratified Boycott Effect


My next paper was written in collaboration with Tom Peacock and John Bush is concerned with the Boycott effect in Magma Chambers. It was be published in the Geophysical Research Letters in March 2004, Vol. 31, No. 5, L05611

The Boycott Effect in Magma Chambers


My research is also concerned with the fundamentals of settling particles in a stratified ambient, the time evolution of the concentration of particles and the instabilities that may result from settling in a stratified ambient. This paper has been published in Physics of Fluids in July 2005, 17 (7): Art. No. 073302.

Hindered settling in a stratified ambient


I then wrote an article written in collaboration with Vincent Piche, Eckart Meiburg and using an idea from Moshe Strauss on numerical simulations of gravity currents. This paper is published in Computers & Fluids, June 2006, 35 (5), pp 492-500.

Evaluation of a simplified approach for simulating gravity currents over slopes of varying angles


This lead to an article written in collaboration with Moshe Strauss, Eckart Meiburg, Ben Kneller and Mike Glinsky on numerical simulations of resuspensing gravity currents. This paper was published in the Journal of Geophysical Research, December 2005, 110 (C12), C12022.

High resolution simulations of resuspending gravity currents: conditions for self-sustainment


I then wrote an article in collaboration with Tom Peacock and Remi Cousin, on instabilities generated in a stratified tank with a moving side-wall. It was published in the Journal of Fluid Mechanics, August 2008, 609, 305-317.

Stability of a stratified fluid with a vertically moving sidewall


I am currently working with undergraduates Sydney Montroy and William Douandju to assess the potential of settling particles to behave as heat carriers. In a separate project, I am collaborating with Dr. Mike Sprague to simulate as directly as possible the process by which a particulate deposit may be suspended by a vigorous flow above it.
