Ben Holtzman

Research Professor

Lamont researcher Ben Holtzman offers his expertise on all things melt and microstructure related. His research resides at the intersection of rock physics, seismology, and geodynamics.  

Heather Savage

Research Professor

Lamont researcher Heather Savage combines rock friction experiments and field studies to investigate multiple aspects of earthquake and fault mechanics. Her current topics of interest include fault strength during earthquakes and earthquake triggering/induced seismicity.  
Christine McCarthy

Research Professor

Lamont researcher Christine McCarthy studies how material behavior (flow, fracture, friction) at various spacial and temporal scales influence microstructure, and vice versa. She is currently measuring effects of tidal forcing on both glacier flow rates and frictional heating of icy satellites.  
 

Sarah Lambart

Postdoctoral Fellow

Lamont Postdoc Sarah Lambart splits her time between rock mechanics and geochemistry to study reaction-driven cracking and permeability changes during carbonation of peridotite.  
 

Hannah Rabinowitz

Graduate Student

Third year graduate student Hannah Rabinowitz studies coseismic shear heating as a way of understanding the energy release of earthquakes and she studies the frictional behavior of sediments as a control on seismic character of subduction zones. She is currently developing an alkenone proxy for fault heating to understand the seismic history of the Japan Trench as recorded in an ocean drill core recovered after the 2011 M9.1 Tohoku-oki earthquake.  
 

Ted Koczynski

Research Engineer

Longtime lab technician, Ted Koczynski keeps everything running smoothly in the rock mechanics lab and is spearheading the rehabilitation of old machinery and the electronic and hydraulic design of the new ice rig.  
 

Michael Nielson

Undergraduate

Undergraduate (2015) Michael Nielson is conducting his senior thesis on the microstructural evolution of polycrystalline ice samples exposed to thermal stresses.  

Research Alumni

NSF-EAR Postdoc fellow Nicholas van der Elst used observational seismology and laboratory friction experiments to learn about earthquakes and fault mechanics.

Columbia undergrad (2013) and research assistant Caitlin Dieck conducted a research project on induced seismicity in the regions around wastewater injection locations.

Columbia undergrad (2013) and research assistant Rachel Sheppard examined shear heating on faults by extracting organic molecules from sedimentary fault rock and analyzing it in a mass spectrometer.

German University of Bochum Postdoc Mandy Duda visited the lab to run cyclic loading experiments under confining pressure using the triaxial apparatus.
