[CMSC 32001, Spring 2018] Topics in PL: Direct Manipulation Programming
I enjoy developing and deploying programming language technology — type systems, synthesis algorithms, and other program analysis techniques — for applications in software engineering and human-computer interaction. Currently, the overarching theme of my research is to develop Direct Manipulation Programming Systems.

[Sketch-n-Sketch] Graphical user interfaces are great, but the lack of programmability in a high-level language makes it difficult to develop complex and reusable content. Sketch-n-Sketch is a direct manipulation programming system for interactively creating documents (such as graphic designs, web pages, and spreadsheets) that aims for a seamless combination of programming and direct manipulation. |

[Deuce] Text editors are great, but coding involves tedious, error-prone edits that hinder productivity and creativity. Deuce is a structure-aware code editor that provides direct manipulation interactions for quickly and correctly performing several common programming and refactoring tasks. |

[Hazel with CU Boulder and CMU] Programming environments typically provide little help when, arguably, programmers need it the most: when editing incomplete (syntactically ill-formed or ill-typed) programs. This project develops semantic foundations for programming environments to edit, run, and reason about programs with holes. |

[Dependent JavaScript @ UCSD] Scripting languages include features that frustrate static reasoning, such as extensible objects, dynamically computed keys, loosely coupled recursion, reflection, and dynamic code loading. This project aims to develop type systems to describe idiomatic programs in scripting languages such as JavaScript, Python, and Ruby. |
 |
[Radar @ UCSD] Defining a dataflow analysis for concurrent programs is complicated by the subtleties of thread interleavings and locking protocols. Radar automatically converts a sequential dataflow analysis to a concurrent one by making use of datarace information from the Relay race detector for C programs. |
 |
[Staged Information Flow @ UCSD] The prevalence of dynamically loaded code makes program analysis for JavaScript difficult. We present a staged approach to tracking information flow that splits the analysis burden between compile-time and run-time. |
 |
[Fine @ Microsoft Research] Modern SMT solvers allow refinement type systems to track security and other complex properties, but they become a large part of the compiler's trusted computing base (TCB). Fine incorporates a type-preserving translation to eliminate the solver from the TCB. Fine is a precursor to MSR's F* language. |
