Long Term Interests

Since the optical properties of liquid crystals are very interesting, besides the current project I am working on, I have other research topics I am interested in, such as liquid crystal lenses in mobile phone camera, liquid crystal spectacle for astigmatism, liquid crystal application in 3D display.

Current Research Projects

Currently I am working on a project for Intel on highly power efficient active matrix displays. The need for low power LC effects for these types of devices will help them to expand into new markets such as book readers.

Interest in short term projects for a company

I would like to do an internship or work on a short term project. Since my career goal is to work in industry and maybe someday I can start my own business, internship or working experience in industry will be invaluable for my future career. Also, internship or working experience in industry can provide me with the very first hand information about the industry needs and new application, which in term enlightens my innovation, and benefits my current research. Considering the progress of my current project, I think the short research project or modeling should be good for me.

Long Term Interests

Generally, optically and electrically related applicable devices, with liquid crystals materials or not.

Current Research Projects

1. Food spoilage detector with double layer alignment film, which prefer different orientation of liquid crystal molecules. By introducing carboxylic acid group in the alignment film, certain amount of amine could react with them, and be detected by observing the director change in the cell.
2. Optical storage materials. Literature study about the materials potential for phase storage has been conducted, and the experimental study of certain glassy material and smectic materials is ongoing, by using the external field and temperature control.

Interest in short term projects for a company

I am interested in device construction and characterization, as well as related modeling.

Long Term Interests

In a long term, I am interested in the liquid crystal devices and applications, both in numerical modeling and experimental setup and demonstration, such as new liquid crystal display technology, liquid crystal beam steering device, liquid crystal lens or any liquid crystal related devices. Other research fields, such as optical communication, nano-technology, biology, etc, that are related or integrated with liquid crystal technology, will also be my research interests.

Current Research Projects

Currently, I am focused on liquid crystal beam steering device and liquid crystal lens devices. Starting from numerical modeling, we propose and develop a tunable liquid crystal polarization grating for beam steering with variable angles. The devices have been set up and characterized experimentally. High diffraction efficiencies (>95%) of the multi-angle beam steering that we propose in the modeling have been implemented and demonstrated. Also we develop a new liquid crystal lens device which can be electronically controlled totally and have variable focal lengths.

Interest in short term projects for a company

Based on my experience, I would like to attend such research projects as liquid crystal based devices and applications. Because I have a lot of experiences both in liquid crystal experiments and numerical simulations, it will be great that the project will have needs both in modeling and device construction. In addition, teamwork is also very important for me. If the projects require me to concentrate on either some specific modeling or device construction, it will be my pleasure to work together with other colleagues.
