Biography

Dr. Einstein has nearly 15 years experience participating in multiple interdisciplinary research teams focused on the development of continuum and multiscale models of organ systems.

A recent focus area is the understanding and prediction of alveolar scale ventilator induced lung injury (VILI). This project combines the co-location of mass spectrometry imaging signals of inflammation biomarkers with imaging-based kinematic and multi scale modeling data. The underlying assumption is that extreme alveolar scale stresses produce well-characterized and well-understood inflammatory pathways. The research thrusts of this project are two fold. First, our work aims to measure and compute local ventilation from CT data from control and VILI subjects and correlate it with MSI data from the same subjects such that differences in the spectra between the two groups can be used to reveal spatial patterns of inflammation.

Second, we are developing a multiscale computational model of the entire rodent respiratory, integrated with a novel and focused imaging study of regional parenchymal strain and alveolar dynamics. Specifically, we will develop imaging-based multiscale computational models that connect airway mechanics with coupled, time-dependent parenchymal and alveolar scale mechanics. Parenchymal scale mechanics will be based on a novel implicit framework for lung parenchyma and will telescope to the alveolar scale, represented by stochastic populations of structural alveoli, articulated in terms of spatially arranged collagen, elastin and alveolar surfactant.

For the last 10 years, Dr. Einstein has lead the Computational Core of PNNL's Virtual Lung project, focusing on the development the open-source technologies that are the foundation for PNNLs organ-to-cell multi scale program. In addition, he provides bioengineering expertise and leadership to assure that simulations are faithful to the underlying biophysics, that models are accurate and well documented, that their predictions accord with experimental data, and that modeling efforts are responsive to the scope of each project. Recent contributions include: development of a novel, thermodynamically based framework for the nonlinear, implicit multi scale mechanics of tissues; the development with of a novel and efficient partitioned approach to multi scale coupling based on true mechanical, chemical and electrical equilibrium; the development of adaptive computational mesh dynamics algorithms for Lagrangian fluid-structure interaction in the heart; and numerous computational geometry and image processing algorithms.
