Our research is situated at the intersection of fluid dynamics and computation with an emphasis on engineering and healthcare applications. In particular, we focus on developing state-of-the-art computational methods that leverage mathematical models and numerical simulations to improve understanding of biological and physiological flows. Our research is driven by the quests to answer questions from both fundamental fluid dynamics problems and practical applications. Our current research involves computational fluid dynamics (CFD), immersed boundary method, high-performance computing, biological fluid dynamics in nature, and biomedical flow in human respiratory system.  

Bio-Inspired Propulsion
We utilize an integrated experimental and computational approach to study the flow physics underlying complex biological locomotion.

Odor-Guided Navigation
We examine the dual functions of insect wings including aerodynamics and olfaction to understand how insects achieve a balance between the aerodynamic performance and olfactory sensitivity during odor-tracking flight.

Metachronal Swimming
We investigate the hydrodynamics of Ctenophores (the largest animals in the world to locomote via cilia) using direct numerical simulations.

Massive Flow Separation
We analyze the vortex formation and flow separation around wing tip of revolving wings using direct numerical simulations.

Human Nasal Airflow


We investigate the nasal sinus disease through CT-based CFD modeling techniques to quantitatively evaluate nasal pathology for individual patients.

Cardiac Blood Flow
We study the cardiovascular flows through image-based computational modeling to investigate effect of valve dynamics on the vortical flow structures and blood mixing.
