My name is Marc Eaddy, and I am a PhD student in the Computer Science Department at Columbia University. I work in the Languages and Compilers Research Group under Alfred Aho. In a previous life, I developed virtual reality games, real-time stock market data applications, and the TV Guide Online Listings.

Research

My goal is to make software easier to develop and maintain by enabling architects, developers, and maintainers to better understand and modularize the concerns (e.g., requirements, features) of a program. When concerns are poorly modularized, programs become more complex, resulting in increased maintenance effort and defects. The inability to effectively modularize a concern is called the crosscutting concern problem—so named because the implementation of the concern is scattered across (crosscuts) the program structure. My research interest is to better understand—and try to solve—the crosscutting concern problem, thereby making programs easier to develop and maintain.

I'm interested in the following questions:

What are the concerns of a program? Where and how are they implemented?
Why does crosscutting occur?
How much is the concern scattered and tangled?
How much crosscutting is in a typical (C, Java, etc.) program?
How does crosscutting affect software quality, program comprehensibility, reliability, etc.?
How can crosscutting concerns be effectively modularized?

Active Projects

ConcernTagger - Concern Analysis for Java Programs

info

ConcernTagger allows you to manually associate requirements, features, bugs, etc. (concerns) with Java code (types, methods, and fields) using drag-n-drop, right click, etc. It computes scattering metrics that measure the number of classes (CDC) and methods (CDO) involved in the implementation, and the distribution of lines across those classes (DOSC) and methods (DOSM).

ConcernTagger is based on the excellent ConcernMapper created by Martin Robillard and Fr?d?ric Weigand-Warr.

Wicca - Static and Dynamic Aspect-Oriented Programming for .NET info | slides | source

Wicca allows you to transform a .NET application using byte-code, source code, or breakpoint weaving at compile-time or runtime. It uses the Microsoft Debugger APIs to update the code of a running program.

Phx.Morph - Aspect-Oriented Programming for .NET doc | slides | source

Phx.Morph is a static weaver that enables Open Classes and Aspect-Oriented Programming for applications written in any .NET language. It uses Phoenix, Microsoft's industrial-strength back-end compiler infrastructure. It is capable of weaving very large programs (1.8 MLOCs) and is the first weaver for .NET to support updating the program's debug information.
