===== Academic Background =====
I received my PhD degree in Mechanical and Aerospace Engineering from Rutgers University in 2012. My PhD studies and dissertation were directed at the complex dynamics and behavior of soft biological cells such as erythrocytes red blood cells), capsules and vesicles in the flow. Healthy erythrocyte membranes possess unique viscoelastic properties that make them extremely deformable.

I studied the intricate dynamics of microsocpic deformable cells in shear flow using the continuum-based Immersed-boundary Front-tracking method. The behavior of single red cells in dilute suspensions may explain the overall behavior and rheology of blood as a dense suspension of high erythrocyte concentration. Altogether, the flow of healthy and disease erythrocytes in blood especially in small vessels has been under extensive investigation due to its physiologic and biophysical significance.

===== Research Interests and Activities =====
I joined Division of Applied Mathematics and the CRUNCH Group at Brown University in 2013 as a post-doctoral research associate. My research interests at Brown is broad and focused on the multiscale, multiphysics nature of biological processes. I am mainly studying blood coagulation and thrombus biochemomechanics in the vasculature especially in aneurysms and aortic dissections.

In computational biophysics, we often use modeling and simulations techniques in one of the spatial and temporal scales: (1) Microscale with techniques such as Molecular Dynamics, (2) Macroscale with techniques such as Continuum Theory and Finite Element Methods, and (3) intermediate Mesoscales with techniques such as Dissipative Particle Dynamics (DPD). These methods at each scale have their advantages and limitations, and multiscale modeling employing techniques across two or more spatial and temporal levels is desirable, indeed, necessary for understanding many phenomena that are intrinsically multiscale.

Blood coagulation is a multiscale process; the mesoscale modeling addresses the associated formation of thrombus, i.e., platelet activation and aggregation, including interactions with red blood cells plus the accumulation of fibrin polymers. Furthermore, the continuum-level modeling of unsteady blood flow interactions with the thrombosed region has to be taken into consideration.
