ECS 124: Fundamental Algorithms in Bioinformatics

ECS 124: Fundamental Algorithms in Bioinformatics (UC Davis). Instructor: Professor Dan Gusfield. This course covers fundamental algorithms for efficient analysis of biological sequences and for building evolutionary trees. This is an undergraduate course taught by UC Davis computer science professor Dan Gusfield focusing on the ideas and concepts behind the most central algorithms in biological sequence analysis. Dynamic Programming, Alignment, Hidden Markov Models, Statistical Analysis are emphasized.

The videos were mostly made in 2002 and edited and somewhat extended in 2014. Despite their age, and despite the fact that "software, databases, websites, and data" in bioinformatics change rapidly, the topics included are still of current importance.
