Reference excerpt

Stephanie Forrest (born circa 1958) is an American computer scientist and director of the Biodesign Center for Biocomputing, Security and Society at the Biodesign Institute at Arizona State University. She was previously Distinguished Professor of Computer Science at the University of New Mexico in Albuquerque. She is best known for her work in adaptive systems, including genetic algorithms, computational immunology, biological modeling, automated software repair, and computer security.

Biography After earning her BA from St. John's College in 1977, Forrest studied Computer and Communication Sciences at the University of Michigan, where she received her MS in 1982, and in 1985 her PhD, with a thesis entitled "A study of parallelism in the classifier system and its application to classification in KL-ONE semantic networks." After graduation Forrest worked for Teknowledge Inc. and at the Center for Nonlinear Studies of the Los Alamos National Laboratory. In 1990 she joined the University of New Mexico, where she was appointed Professor of Computer Science and directs the Computer Immune Systems Group, and the Adaptive Computation Laboratory. From 2006 to 2011 she chaired the Computer Science Department. In the 1990s she was also affiliated with the Santa Fe Institute, where she was Interim Vice President for the 1999–2000 term. In 1991, Forrest was awarded the NSF Presidential Young Investigator Award, and in 2009 she received the IFIP TC2 Manfred Paul Award for Excellence in Software. In 2011, she was awarded the ACM - AAAI Allen Newell Award.

Work Forrest's research interests are in the field of "adaptive systems, including genetic algorithms, computational immunology, biological modeling, automated software repair, and computer security." According to the National Academies her research since the 1990s has included "developing the first practical anomaly intrusion-detection system; designing automated responses to cyberattacks; writing an early influential paper proposing automatic software diversity and introducing instruction-set randomization as a particular implementation; developing noncryptographic privacy-enhancing data representations; agent-based modeling of large-scale computational networks; and recently, work on automated repair of security vulnerabilities. She has conducted many computational modeling projects in biology, where her specialties are immunology and evolutionary diseases, such as Influenza and cancer."

Worked examples

Example 1 — a first encounter with Stephanie Forrest

Start with the simplest possible case. Write down what Stephanie Forrest claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Stephanie Forrest before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Stephanie Forrest ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Stephanie Forrest

In research: Stephanie Forrest appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Stephanie Forrest in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Stephanie Forrest is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950s births, 21st-century American women, American computer security academics, so understanding it makes those chapters shorter.
In everyday life: Look for Stephanie Forrest outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
