**Academic Interests: **fluid dynamics, industrial mathematics, liquid crystals, filtration, biological fluid dynamics

### About Me

I work on a variety of physically-motivated problems, mainly fluid-dynamical in nature, and many of which arise in industrial applications. More details of specific projects may be found under the "Research" tab. I co-organize the annual MPI (Mathematical Problems in Industry) workshop, which facilitates collaborations between industrialists and academic applied mathematicians. I am currently Associate Dean for Research and Graduate Education within the College of Science and Liberal Arts at NJIT.

### Education

I work on a variety of physically-motivated problems, mainly fluid dynamical in nature, and many of which arise in industrial applications. I use mathematical modeling coupled with asymptotic analysis to derive tractable, predictive models of real systems.

### Current Research
