About this STEMCasts® episode:
The advent of the -omics age, coupled with the development of robust bioinformatics tools, has granted scientists a window into the molecular and cellular processes which are the root causes of human disease. Simultaneously, large patient datasets have been made publicly available via massive online repositories and are invaluable resources for bioinformatics students.
This STEMCasts® episode will teach students the fundamental skills necessary and inspire a
passion for future explorations in bioinformatics. Due to the extensive nature of the material, the webinar will be 2 hours. We will also host a special Q&A session with renowned expert Dr. Sudeshna Das, Assistant Professor of Neurology at Harvard Medical School.
Meet Your Instructor:
