Current Graduate Research:

I'm interested in developing core reinforcement learning (RL) methodologies for safety-critical applications in the real world, such as connected automated vehicles, smart cities, urban air mobility, and urban search-and-rescue missions.

Some topics on which I am working with Professor Huy Tran at Tran Research Goup are:

  1. Developed safe and verifiable AI and deep reinforcement learning framework using formal methods
  2. Designed a neural network from scratch, which infers robot behaviors in human-readable forms
  3. Applying the framework for motion planning of robots and autonomous vehicles (Sim2Real)

Previous Udergraduate Research:

I was widely interested in aerodynamics and collaborative unmanned vehicles in the context of integrated intelligent transportation where all the aerial, ground, and marine automated vehicles require optimizations of the design in terms of fluid dynamics and controls on the interactions of vehicles. This interest led me to work in two laboratories: one is computational fluid dynamics lab, and the other is connected automated vehicles and highway lab.

Some topics on which I have worked with Professor Jennifer Franck in the CFD lab are:

  1. Dynamic Mesh Morphing: developed and implemented a dynamic mesh generation library for harbor seal whiskers for a CFD solver (OpenFOAM).
  2. Flow Control: evaluated the parametric influences of harbor seal whiskers on hydrodynamics and frequency response.
  3. Comformal Mapping: developed a mesh-generation library using Schwartz-Christoffel conformal mapping for 2D geometries on MATLAB® .

Another set of topics I have worked with Professor Bin Ran in the CAVH lab are:

  1. Mixed Traffic: built simulation models to evaluate how platooned automated vehicles can improve the network capacity on highways between Madison, WI and Chicago O'Hare Airport.
  2. Car-following Model: investigated the way to dynamically assign costs for individual vehicles to join and leave platoons.
  3. Weather Condition: simulated how the network capacity of highway can change under the snow.
