Antoinette Maniatty
Associate Chair for Graduate Studies and Associate Professor
Department of Mechanical, Aerospace, and Nuclear Engineering
Rensselaer Polytechnic Institute

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

Career Highlights:
After spending a year as a visiting lecturer at the University of Natal in Durban, South Africa, Maniatty joined the faculty at Rensselaer in 1992. She has earned numerous honors, including being among just four women scientists and engineers nationwide to be awarded a fellowship by the Henry Luce Foundation. She received a National Science Foundation Young Investigator Award in 1993, was an invited participant in the National Academy of Engineering's First Annual Symposium on the Frontiers in Engineering in 1995, and was invited to serve as a researcher at the Technische Hochschule Darmstadt, Institut fuer Mechanik in Germany in 1996. 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.

Maniatty has been involved in conference organization for several professional conventions, both locally and internationally. She served on the Local Organizing Committee of the 4th International Conference on Constitutive Laws for Engineering Materials in 1999 at Rensselaer and as organizer and chair of the Eighth Inverse Problems in Engineering Seminar and Workshop on Selected Topics in Inverse Problem Solving at Rensselaer in 1997. The same year, she served as organizer and chair of an invited session on modeling and design of forming processes at COMPLAS 5: Fifth International Conference on Computational Plasticity in Barcelona, Spain.

Maniatty is a member of the American Academy of Mechanics, the American Society of Mechanical Engineers, the US Association for Computational Mechanics, the American Society of Manufacturing Engineers, Tau Beta Pi, and Pi Tau Sigma.

Research Areas:
Maniatty's research is in the broad field of computational solid mechanics. She investigates inverse problems with either unknown boundary conditions or unknown parameters. Applications include optimizing 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.

Maniatty also models crystalline materials. Studies are underway using micromechanics as a basis for modeling large strain metal forming problems. Her research also includes modeling stresses and defect formations in thin metal films on semiconductor wafers.
