During my chemistry degree, I was completely oblivious to digital marketing. I knew what it was, but I didn’t know anything about it or how to get started in it.

It wasn’t until I started my first job as a scientist, that I accidentally started learning about digital marketing through some side projects on spent time on during my weekends and evenings.

Although many years have passed between now and when I started, I wish I started earlier.

But if you are new to digital marketing, or you want to get better, there are plenty of great resources online that can help you get started.

Although all of these resources are general – and not life science related – if you are considering learning about digital marketing in combination with life sciences, healthcare or medical, please get in touch with me as I would love to hear from you!

This list was initially compiled in January 2022 and was last checked in March 2024, but if something has disappeared or is no longer available, please contact me and let me know!

Alternatively, if you have a resource that you would like to recommend I add, then please reach out to me!
