Gregor Kiczales is an American Canadian computer scientist. He is currently a professor of computer science at the University of British Columbia in Vancouver, British Columbia, Canada.[1] He is best known for developing the concept of aspect-oriented programming,[2] and the AspectJ extension to the Java programming language, both of which he designed while working at Xerox PARC.[3] He is also one of the co-authors of the specification for the Common Lisp Object System,[4] and is the author of the book The Art of the Metaobject Protocol, along with Jim Des Rivières and Daniel G. Bobrow.[5]
Most of Kiczales' work throughout the years has been focused on allowing software engineers to create programs that look as much as possible like their design, to reduce complexity and make code maintenance easier, ultimately improving software quality.
Kiczales was raised in Winchester, Virginia. He attended Middlesex School, graduating in the class of 1978.[6]
After pursuing undergraduate studies at MIT, Kiczales started his research career in 1980 at the MIT Lab for Computer Science, where he stayed until 1983. In 1984, he joined the Xerox Palo Alto Research Center software research lab as member of research staff, becoming principal scientist in 1996. Throughout his time at PARC, Kiczales developed some of his most important research works, including aspect-oriented programming and AspectJ. He left PARC in 1999 to focus on computer science education.[7]
In 2000, he moved to Canada and joined the Department of Computer Science at the University of British Columbia as a tenured professor.[8] At UBC, Kiczales started the Software Practices Lab[9] and designed a number of courses related to software engineering and programming languages. Most importantly, he designed CPSC 110, the introductory programming course in the UBC curriculum, which students take in their first year of undergraduate studies. The course focuses on systematic program design by means of design recipes.[10]
In 2002, he co-founded Intentional Software with Charles Simonyi, but then left the company in 2003 in order to return to UBC.[11]
In 2012, he won the Senior AITO Dahl-Nygaard Prize for his work on the Common Lisp Object System,[12] and was named an ACM Fellow for his contributions to aspect-oriented programming.[13]
In July 2017, he was appointed executive director of UBC Extended Learning.[14]
In April 2025, he departed from his role as an instructor for the introductory first year undergraduate Computer Science course at UBC which he designed, CPSC 110.[10]

In computer science, a metaobject is an object that manipulates, creates, describes, or implements objects (including itself). The object that the metaobject pertains to is called the base object. Some information that a metaobject might define includes the base object's type, interface, class, methods, attributes, parse tree, etc. Metaobjects are examples of the computer science concept of reflection, where a system has access (usually at run time) to its own internal structure. Reflection enables a system to essentially rewrite itself on the fly, to alter its own implementation as it executes.
The Art of the Metaobject Protocol (AMOP) is a 1991 book by Gregor Kiczales, Jim des Rivieres, and Daniel G. Bobrow (all three working for Xerox PARC) on the subject of metaobject protocol.
Common Lisp (CL) is a dialect of the Lisp programming language, published in American National Standards Institute (ANSI) standard document ANSI INCITS 226-1994 (S2018) (formerly X3.226-1994 (R1999)). The Common Lisp HyperSpec, a hyperlinked HTML version, has been derived from the ANSI Common Lisp standard. The Common Lisp language was developed as a standardized and improved successor of Maclisp. By the early 1980s, several groups were already at work on diverse successors to MacLisp: Lisp Machine Lisp (aka ZetaLisp), Spice Lisp, NIL and S-1 Lisp. Common Lisp sought to unify, standardize, and extend the features of these MacLisp dialects. Common Lisp is not an implementation, but rather a language specification. Several implementations of the Common Lisp standard are available, including free and open-source software and proprietary software products. Common Lisp is a general-purpose, multi-paradigm programming language. It supports a combination of procedural, functional, and object-oriented programming paradigms. As a dynamic programming language, it facilitates evolutionary and incremental software development, with iterative compiling into efficient runtime programs. This incremental development is often done interactively without interrupting the running application. It also supports optional type annotation and casting, which can be added as needed at the later profiling and optimization stages, to permit the compiler to generate more efficient code. For instance, fixnum can hold an unboxed integer in a range supported by the hardware and implementation, permitting more efficient arithmetic than on big integers or arbitrary precision types. Similarly, the compiler can be told on a per-module or per-function basis which type of safety level is wanted, using optimize declarations. Common Lisp includes the Common Lisp Object System (CLOS), an object system that supports multiple dispatch (multimethods) and method combinations. It is often implemented with a metaobject protocol. Common Lisp is extensible through standard features such as Lisp macros (code transformations) and reader macros (input parsers for characters). Common Lisp provides partial backwards compatibility with Maclisp and John McCarthy's original Lisp. This allows older Lisp software to be ported to Common Lisp.

Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
