{c}
<Jeff Erickson> is a <computer scientist> whose work concerns <computational geometry>, <computational topology>, <graph algorithms> and <data structures>. His research also examines how students learn to design <algorithms>.<Jeff Erickson's Illinois research homepage>[Research description]{ref}
His open textbook <Algorithms by Jeff Erickson> develops algorithm design through explicit examples, proofs and analysis. Its treatments of <dynamic programming> and <depth-first search> show complementary organizing ideas: reuse results of smaller subproblems, or explore the structure of a <graph>. The explanations connect the procedure with the invariant or recurrence that justifies it.<Algorithms by Jeff Erickson>[Chapters on dynamic programming and depth-first search]{ref}
