In 2015, Das reviewed the research on measuring the speed of earthquake propagation since her 1977 paper, including a consideration of the theoretical modeling, methods for analyzing seismic waveforms, field examples in which these methods have been applied, laboratory experiments, and examples of

Das's research is on earthquake source mechanics. Her graduate research centered on the propagation of cracks and she developed a numerical model of earthquakes that enabled the prediction of aftershocks after an earthquake. While at Lamont
Doherty Earth Observatory, Das worked on the relevance of
