My focus in the project is to solve a functional synthesis problem, which involves synthesizing a genetic circuit from a library of well-characterized modules that implements a desired specification given in signal temporal logic (STL).

Additionally, I have been involved in the development of STL#, an extension to STL that includes syntax and semantics for composition of temporal logic formulae.  Using STL#, a designer can computationally compose STL formulae together hierarchically.\u00a0 Currently, I am looking into different methods for exploring the design space of a genetic circuit given a library of modules.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In general, my interests lie in applying formal verification methods to systems in a variety of disciplines.
