Senior design projects in this lab

The Web Camera Mouse with Smart Base utilizes part of a user's face to move a mouse on a computer screen. If the user moves out of the range of the web camera, the smart base rotates a predetermined angle to put the user's face back into range. The Phase II design takes the  mouse to the next level, allowing the user to click the mouse. Additionally, it tracks the user's face and tilts or pans the monitor to follow the user in real time rather than in predetermined angles. This product is intended for handicapped individuals and those looking to free their hands in order to increase their productivity.

Research projects in the lab
  • Molecular dynamics simulation of high electric pulse effects on bilayer
    membranes.
    Electroporation or electropermeation has been intensely studied and applied in the areas of molecular biology, biotechnology and medicine during the last two decades. This technique is to use very intense electrical pulses to introduce pores on biological cellular membranes. These pores can allow large-sized molecules to go inside of the membrane, such as drugs and DNA. Applications include clinical electroporation therapy (ETP) for treating various tumors and cancers and gene therapy for gene delivery. The figure shows how a water channel forms on a DPPC membrane when nanosecond high-intensity electrical pulses are applied.
  • Molecular dynamics study of conformational transitions of
    poly(N-isopropylacrylamide) hydrogels and graphite oxide (GO).

    Poly(N-isopropylacrylamide) (PNIPAM) as one of the thermosensitive polymers, has a coil-to-globule transition as the temperature is raised through the lower critical solution temperature (LCST). The transition has important applications in drug delivery, medical diagnostics, tissue engineering, electrophoresis and separation. Due to the special physical and chemical properties of graphene oxide (GO), the GO film has attracted attention in next-generation electronic devices such as nonvolatile and thin film transistors. In this project, we are going to make a PNIPAM-GO thin film and study the possible new properties through molecular dynamics simulation.
