 Currently, the lab is pursuing the following projects: [**Modular Deep Learning**](https://lab-design.github.io/projects.html#modular-deep-learning), which investigates the decomposition of deep neural networks into modules to enable reuse, replacement, and independent evolution of those modules, [**Boa**](http://boa.cs.iastate.edu), a domain-specific language and infrastructure for mining software repositories and [**D4**](https://www.nsf.gov/awardsearch/showAward?AWD_ID=1934884&HistoricalAwards=false) (Dependable Data-Driven Discovery), which works on understanding of the risks to the dependability of data-science lifecycles, to formalize the rigorous mathematical basis of the measures of dependability for data-science lifecycles, and to identify mechanisms to create dependable data-science lifecycles.
 
-Our past projects include [**Panini**](http://paninij.org), a language designed to enable safe and efficient concurrent programming by construction and [**Ptolemy**](http://ptolemy.cs.iastate.edu), a language that strives to balance expressiveness and modular reasoning for crosscutting concerns. While active work is not ongoing on these projects, interested students may propose collaborative ideas that we would continue to consider.
