I have given several talks for the general public, and even more for scientific audiences. Here are slides from some of these talks. (this page is very old, will update in 2008)

Title	Audience	Length	Description
Biology/Bioethics/BioPhilosophy/Bio*
Philosophy meets Biology	General public	50 minutes	New biological problems that strain current philosophical assumptions.
Evolutionary Computation
Introduction to evolutionary computation	computer science students	50 minutes	Using simulated evolution to solve problems computationally (GA, GP, etc.)
Using evolution to build computing software and hardware	Biologists, computer scientists, or general public	15, 30 or 50 minutes	Evolutionary computation (EC) techniques, including genetic algorithms (GA) and genetic programming (GP), for building computer programs and computing circuits
EC hardness	EC researchers	50 minutes	thoughts on how to measure problem hardness in EC.
Robustness of evolved circuits	EC researchers	15 minutes	Evolved sorting networks are fail less catastrophically than hand-designed ones when subjected to point circuit failures.
Using GAs for building stock market portfolios	computer scientists	50 minutes	Solving multi-objective functions (e.g. risk, return) with subtractive constraints (e.g. long and short positions), stock market portfolio example
*Other CS Stuff*
What machines can never learn	general public	50 minutes	inductive inferencing: computational limits to what machines can learn
Pseudo randomness	computer science students	50 minutes	Different techniques for generating pseudorandom number sequences, measuring their quality
DNA computing	general public	50 minutes	Computing with DNA
Quantum computing	general public	50 minutes	how to use quantum mechanics to speed up computations
*Other Stuff*
Doing proofs	computer science students	50 minutes	Strategies for doing mathematical proofs
