Harold Ossher, from IBM T.J. Watson Research Center, will be visiting here on
Thursday, Nov. 29. He's done a lot of work in software engineering and
programming languages, including in the currently very active area of
"multidimensional separation of concerns" (which includes aspect-oriented
programming). Here's an abstract from a recent talk he gave:

Multi-Dimensional Separation of Concerns
Harold Ossher
IBM Thomas J. Watson Research Center
Multi-dimensional separation of concerns is a new approach to
constructing, integrating and evolving software. Developers can
decompose and organize code and other artifacts according to multiple,
arbitrary criteria (concerns) simultaneously--even after the software
has been implemented--and synthesize or integrate the pieces into
larger-scale components and systems. This facilitates several common
development and evolution activities, including: adaptation,
customization and instrumentation; addition and mix-and-match of
features; reconciliation and integration of multiple domain models;
reuse and product line management; extraction or replacement of
existing parts of software; and "on-demand remodularization."
In this talk, I will introduce and illustrate the concepts behind
multi-dimensional separation of concerns, discuss how it relates to
aspect-oriented software development, and briefly describe Hyper/J,
our support for Java(tm) developers. I will discuss experience with
Hyper/J, and a number of interesting and challenging research
problems that remain.

He probably won't be giving a talk here, but he'd like to talk to interested
students. There should be a sign-up web page available soon, if not already.
