Abhinendra Singh

  • Postdoctoral Researcher

Abhi obtained his PhD at the University of Twente in The Netherlands, where he was co-advised by Professor Stefan Luding and Dr. Vanessa Magnanimo investigating the flow behavior of the dense granular material. He moved to the Levich Institute in the City College of New York after finishing his PhD, where he developed the constitutive model for dense frictional suspensions as a part of post-doctoral research co-supervised by Professors Jeff Morris and Morton Denn.

Abhi was recently awarded the 2020 Publication Award for his work entitled ‘A constitutive model for simple shear of dense frictional suspensions.’ JOR 62, 457 (2018); https://doi.org/10.1122/1.4999237

Abhi’s research interests include studying the flow and jamming of particulate systems such as dense suspensions (like cornstarch) and dry grains (like glass beads). He uses numerical simulations to seek the understanding of the observed experimental behavior of non-Newtonian features observed in both dense suspensions and dry grains.

Abhi is currently a joint postdoctoral scholar between Professor Heinrich Jaeger at the JFI and Professor Juan de Pablo at the Pritzker School of Molecular Engineering. His research efforts focus on simulating suspension dynamics. He develops numerical schemes for characterizing, visualizing, and understanding the continuum behavior of particulate flows including dry/wet granular flows, dense suspensions, and emulsions.
