given your phd I'd suggest you focus on research/data science roles over and above web development.
Python is also a really good choice in language; flexible, easy to learn and have lots of science/data libraries to have fun with.
If I where you, I'd check out websites such as Coursera, Edx and be on the look out for anything that seems to merge your interests.
For example:
- https://www.coursera.org/specializations/bioinformatics
- https://www.edx.org/course/computational-neuroscience-neuronal-dynamics-of-cognition-0
- https://www.coursera.org/learn/modeling-simulation-natural-processes
For what it is worth, I think you may struggle to get a coding job without at least something on the CV that suggests you can (a) do it and (b) are willing. One or two online courses should probably help you figure out a path.
