A simulation-based technology for stochastic modeling, sensitivity analysis and design optimization, aimed at development of next-generation micro-fluidic devices for biomedical applications. - During an epidemic, testing numerous patients puts a heavy burden on the healthcare sector, while infections
continue to rise in the absence of a treatment. In such a scenario, micro-fluidics technology can be used to
develop affordable point-of-care diagnostic tools for detecting infected patients early, and effective drug
discovery platforms for synthesizing therapeutic drugs. The development of such devices is extremely
challenging, needing expertise in multiple disciplines (e.g. physics, chemistry, biology), and understanding the
interplay between variables that influence operating performance requires computational assistance. While
advanced design software may be adopted to simulate the performance of such devices, precise knowledge of
prediction reliability is of paramount importance to ensure their suitability for clinical decision-making.
Therefore, the long term objectives of this project are to commercially introduce a new paradigm of digital
engineering design that focuses on evaluating the fluctuations in performance outputs due to variability in input
parameters and to demonstrate the relevance of such a simulation-based technology through specific
application to development of micro-fluidic biomedical devices. The envisioned proof-of-concept is a modular
computational system with practical commercial applications in the healthcare sector that demonstrates how
scientific computing, numerical simulation & artificial intelligence modeling approaches can lead to an
increased understanding of the performance of a micro-fluidic system subject to operating uncertainty, and
enable robust design optimization. The proposed approach is to employ innovative stochastic spectral methods
& advanced numerical schemes to conduct computationally efficient, high fidelity simulations involving
uncertainty quantification & propagation, model sensitivity analysis, and finite element analysis for the
engineering evaluation of progressively complex micro-fluidic device designs, and to incorporate artificial
intelligence based meta-modeling techniques to perform design space exploration for performance
improvement of such devices. The R&D efforts would establish the technical merits & feasibility of a simulation-
based technology for predictive stochastic analysis & multi-disciplinary engineering evaluation of novel micro-
fluidic devices that addresses the need for efficient & accurate performance assessment of such devices in
practical (often uncertain/variable) operating scenarios. It could subsequently be utilized by biomedical
engineers to foster the rapid development of robust next-generation devices that operate reliably within desired
operating performance specifications, such as diagnostic tools with improved detection sensitivity & specificity,
and drug discovery platforms with enhanced reconstitution of complex cellular interactions. These can play a
crucial role in rapid short-term response to control the spread of infections & to mitigate disease outbreaks,
while also offering improved solutions for enhancing long-term access to primary healthcare & comprehensive
disease treatment, thereby significantly improving public health, particularly in resource constrained settings.
