Yao and his team in the
Manufacturing Research Laboratory (MRL)
are interested in multidisciplinary research in manufacturing and
design, nontraditional manufacturing, laser materials processing, laser
assisted material removal, shaping, and surface modification, laser
applications in industry and art restoration, robotics in industry and
health care industry.
Laser Manufacturing Group
research projects include
Forming and Laser Correction: Laser forming (LF) of sheet metal components and tube requires no
hard tooling and external forces and therefore suited for die-less rapid prototyping and low-volume, high-variety production of
sheet metal and tube components.
Modification of NiTi Shape Memory Alloys and Biodegradable Polymers:
By controlling the thermal evolution resulting from laser irradiation,
for both melt-mediated and solid phase processes, spatial control over
traditional properties such as mechanical, electrical and thermal, in
addition to so-called non-traditional material responses such as
biodegradability and shape memory responses may be realized.
laser processing of dielectrics and semiconductors: Femtosecond laser processing of
transparent non-crystalline solids employs non-linear absorption to
induce structural changes within the target material interior without
affecting its surface. The same laser source is used for sub-micron
size texturing and simultaneous crystallization of amorphous silicon which has potential
application in thin-film based solar cell.
Advanced Robotic Health Care Group
Current research projects include
Robotic Preparation of cDNA from Single Cells:
Develop an instrument that
will couple the power of multidimensional microscopy with that
of DNA array technology (A joint research project with St.
Luke's-Roosevelt Hospital Center).
