Antoinette Maniatty

Clare Boothe Luce Associate Professor
Department of Mechanical, Aerospace, and Nuclear Engineering

Education:

B.S., Mechanical Engineering, Rensselaer Polytechnic Institute, 1987
M.S., Mechanical Engineering, University of Minnesota, 1988
M.S., Mechanical Engineering, Cornell University, 1990
Ph.D., Mechanical Engineering, Cornell University, 1991

Career Highlights:

After spending one year as a visiting lecturer at the University of Natal in Durban, South Africa, Maniatty joined the faculty at Rensselaer in 1992. She is currently the Clare Boothe Luce Associate Professor – one of just four women scientists and engineers nationwide to be awarded a fellowship by the Luce Foundation in 1992. In 1993, she received a National Science Foundation Young Investigator Award. Maniatty was an invited participant in the National Academy of Engineering's First Annual Symposium on the Frontiers in Engineering in 1995. A year later, she was invited to serve as a researcher at the Technische Hochschule Darmstadt, Institut fuer Mechanik in Germany. In 2000, Maniatty was chosen for membership in the Defense Science Study Group (DSSG), which introduces outstanding young scientists and engineers to challenges facing national security. The following year, Maniatty served as the first Loewy Visiting Professor in the Materials Science and Engineering Department at Lehigh University. She is a member of the American Academy of Mechanics, the American Society of Mechanical Engineers, Tau Beta Pi, and Pi Tau Sigma.

Research Areas:

Maniatty's general area of research is in the broad field of computational solid mechanics. Specific problems being currently investigated include modeling crystalline materials and inverse/optimization problems. In the area of modeling crystalline materials, work is being done to use micromechanics as a basis for modeling large strain metal forming problems. Work is also being done to model stresses and defect formation in thin metal films on semiconductor wafers. Maniatty's other area of research involves inverse and optimization problems. This work investigates problems with either unknown boundary conditions or unknown parameters. Applications include optimization of forming processes, determining elastic stiffness in human tissue from ultrasonic measurements of displacements, and determining unknown boundary conditions in contact problems for modeling and predicting wear.
