AT first, before embarking to shift from wet bench lab to computational science, you should have a good background in Bioinformatics and programming ( python and R in particular ). There are some wonderful online MOOCs that could be of paramount benefit to you and here are some :
1. https://www.coursera.org/course/bioinformatics
2. https://www.coursera.org/course/bioinformatics2
3. https://www.coursera.org/learn/bioinformatics-methods-1
4. https://www.coursera.org/learn/bioinformatics-methods-2
5. https://www.coursera.org/course/pythonlearn
6. https://www.edx.org/course/cs-all-introduction-computer-science-harveymuddx-cs005x
I hope this helps
