I am a Professor of Mathematical Sciences at the NJIT, a founding member of the Center for Applied Mathematics and Statistics, and a member of the Particle Technology Center at NJIT. My research focus is on dynamical systems theory and applications. Dynamical systems (nonlinear dynamics) theory is a rich amalgam of techniques from algebra, analysis, chaos theory, differential equations, differential geometry, algebraic and differential topology, fractal geometry, integrability theory, geometry and singularity theory, and has important applications in every branch of science and engineering, which may account for my eclectic interests and the time I have devoted to collaborative research in various fields of engineering and science. In addition to several fundamental theoretical contributions, I have worked on many applied problems in such areas as acoustics, automated assembly, biological populations, computational topology, computer aided geometric design, fluid mechanics, granular flows, plant growth (phyllotaxis), relativistic and quantum physics, rough surface analysis and vortex dynamics. Some of my research has been supported by grants from the National Science Foundation and Office of Naval Research.

In addition to my research, for which I received the Harlan Perlis Research Award from NJIT in 1993, I am devoted to instruction at both the undergraduate and graduate level and have won several teaching awards, including a Mathematical Association of America Award for Distinguished College or University Teaching of Mathematics in 2015. I have developed perhaps a dozen graduate and undergraduate courses and was a principal contributor to the development of the Ph.D. Program in Mathematical Sciences at NJIT.

I am an associate editor of Mechanics Research Communications and serve on the editorial boards of several mathematics and mathematical physics journals and a book series in mathematical physics.

** Manufacturing Automation**

- Analysis and Representation of Swept Volumes: We developed characterizations of swept volumes of general piecewise-smooth objects in terms of trajectories of differential equations that we call the sweep differential equation(SDE) and the sweep-envelope differential equation(SEDE). Both SDE and SEDE based methods have been applied to solve real world problems in NC machining, robot motion planning and virtual design and manufacturing.

- Swept Volume Algorithms and Software: Using SDE and SEDE theory as a framework, we developed fast, efficient and robust algorithms for computing and graphically representing swept volumes. These algorithms are being used to create computer software that can be interfaced with commercial software in order to obtain more useful software for a variety of manufacturing applications.
