Welcome to my Web site !
I am the founding Director of the School of Engineering and Computer Science. My background is in robotics. My research interests are: (1) Haptic interfaces for virtual reality, (2) Fuzzy logic controllers, and (3) Technology-assisted delivery of laboratory courses in distance education.
Haptic interfaces are devices that provide force and tactile feedback to the user as he interacts with objects in a computer-generated virtual world. Our research effort is focused on development of portable haptic devices and actuators. With the help of such devices and by wearing a head-mounted display and position sensors, we can step inside a computer-generated virtual world to interact with virtual objects. For example, we can "hold" two digital parts (CAD models) in our hands and try to assemble them while feeling the interaction forces through the haptic interface. Such a system would allow evaluation of designs thoroughly before a physical prototype is manufactured leading to reduced time to market and cost. Other uses for haptics have been realized in areas of training, such as medical students practicing virtual surgery, soldiers performing a simulated military operation, in minimal invasive robotic surgery, teleoperated robots, prosthetics and robotic neuro-rehabilitation.

Fuzzy logic controllers model the human decision making process with a collection of rules. Although the theory has been rapidly developing we don't have a formal procedure that can be followed in designing a fuzzy controller yet. Our research involved developing a method that treated the design of the rule base as a multivariate optimization problem. For further information, please click the research link below.
Technology-assisted delivery of laboratory courses at a distance over the Internet is a challenge many universities face as they develop their distance education programs. Today the Internet is widely used in courses with no laboratory component for distributing course syllabi, notes, assignments and solutions, etc. Our research effort focused on development of technologies and curriculum for remote laboratories over the Internet.
