[12] He is also known for having developed, in his PhD thesis, the extension of DLVO theory that describes the stability of colloidal systems in fluid dynamic conditions based on a new solution (developed using the method of matched asymptotic expansions) to the Smoluchowski convection–diffusion equation.
Also in his PhD thesis, he developed a formula for the shear modulus of colloidal nanomaterials,[14] which has been confirmed experimentally in great detail.
[1][6] In 2021 he led a team that theoretically predicted and computationally discovered well-defined topological defects as mediators of plasticity in amorphous solids.
[18] This discovery has been later successfully confirmed independently by a research group led by Wei-Hua Wang and Walter Kob.
[19] In January 2022 he proposed an approximate solution for the random close packing problem in 2D and 3D,[20] which received multiple comments online.
