Research
| My research focuses on the frontiers of soft matter physics, granular physics, and the physics of complex systems, utilizing advanced simulation techniques such as Discrete Element Method (DEM), Computational Fluid Dynamics (CFD), and Finite Element Method (FEM) combined with machine learning to explore innovative solutions to fundamental and applied scientific challenges. | |
| 1. | Rheology of Bubble Flow in Microfluidic Channels: I investigate the flow behavior of bubbles in 2D microfluidic geometries, focusing on the influence of geometry, friction, and other key parameters. This research aims to optimize microfluidic systems, with potential applications in healthcare diagnostics and biotechnology. |
| 2. | Granular Segregation and Mixing: My work explores the mechanisms of granular segregation and mixing, addressing critical issues in industrial applications such as pharmaceuticals, food processing, and construction materials. Understanding how geometry, friction, and flow conditions affect segregation can enhance process efficiency and reduce operational costs. |
| 3. | Physics of Soft Bioparticles and Bubbles: I study the dynamics of soft bioparticles and bubbles to gain insights into biological systems. Specifically, this research contributes to understanding blood flow dynamics and cancer progression in microvascular systems, paving the way for advancements in biomedical science.. |
| 4. | Granular Flow in Natural Phenomena: Granular physics also provides a framework for understanding large-scale natural events such as landslides, avalanches, and desert dune dynamics. This research seeks to model these phenomena to predict and mitigate their effects, improving disaster management strategies. |
| 5. | Environmental and Astronomical Pattern Formation Using Machine Learning: Leveraging machine learning algorithms, I study pattern formation in granular flows, enabling the identification of emergent structures and behaviors. I also analyze astronomy big data to uncover patterns in the large-scale structure of the universe, contributing to our understanding of dark matter and the evolution of cosmic structures. |
| 5. | Machine Learning for Environmental Change: My interdisciplinary research applies machine learning to track environmental changes, aiming to identify trends and predict long-term effects of climate change, deforestation, and desertification. |
| By integrating machine learning with traditional physics methodologies, my research not only addresses pressing industrial and environmental challenges but also contributes to the cutting-edge scientific inquiries into the fundamental physics of soft matter and the universe. | |
