A nonlinear manifold-based reduced order model
A new perspective on model reduction for nonlinear multi-scale analysis of heterogeneous materials. In this work, we seek meaningful low-dimensional structures hidden in high-dimensional multi-scale data.
Rates of bond breaking between myosin and actin at different nucleotide states are systematically extracted for the first time
Recently, unusually high detachment rates of a myosin from actin were reported with a force spectroscopy technique. Here, we show that these high rates may be due to the coupling between bond breaking and state transition. Based on a kinetic model for single myosin, rates of bond breaking between myosin and actin at different nucleotide states are systematically extracted for the first time. Our results clearly indicate that myosins may adopt much higher transition rates than bond breaking rates at different nucleotide states at relatively low forces.

Molecular dynamics modeling of NiTi superelasticity in presence of nanoprecipitates
The presence of nano-sized coherent precipitates is well known to have crucial impact on the mechanical behaviors of a broad class of shape memory alloys. The local stress gradient at the matrix-precipitate interface is predicted as induced by inter-lattice atomic disregistry. Due to the presence of the local disturbance fields, the preference for activating different martensitic variants, given the uni-directionality thereof, is influenced substantially.

PhD studentship on Validation of crystal plasticity models in 3D policrystals at Portsmouth University (UK)
Fatigue life prediction in the aerospace components relies on fracture mechanics for relatively long cracks (>1mm). Nevertheless, most of the fatigue life is spent while the crack is relatively short (<1mm). However life of short cracks is far from well understood leading engineers to apply over conservative safety factors which involves environmental and economic losses. The material microstructure is responsible for the large life uncertainty in short cracks.
