The path

Six steps to becoming a principal investigator

There is no single way in, but the route tends to follow the same arc. These steps take you from the foundations through real experience to a position that stays durable as AI reshapes the work.

Step 1
Build the educational foundation

Usually a graduate or professional degree (master's, PhD, or equivalent licensure).

Step 2
Develop the core skills

Principal Investigators draw most on Biology, English Language, Medicine and Dentistry, and Chemistry. Build these deliberately through coursework, projects, and real work.

Step 3
Gain hands-on experience

Experience is what turns study into an offer. Build proof through internships, junior roles, or real projects that show you can do the principal investigators work, not just describe it.

Step 4
Earn the credentials that matter

Credentials signal readiness. Earn the certifications or licences your target employers actually screen for, which for principal investigators can range from a degree to specific professional certificates.

Step 5
Get in through an adjacent role

Many principal investigators arrive from related roles such as Geneticists, Biochemists and Biophysicists, Physicians, Pathologists. These are realistic entry points if a direct path is not open yet.

Step 6
Position for durability, not just entry

Principal Investigators sit at 26/100 on the AI exposure scale (low exposure). As you enter, aim for the judgment, accountability, and specialist layer of the role, which is what holds value as AI absorbs the routine work.

"The report showed me exactly where my weak spots were and what to work on next. Much more useful than generic career advice."

Thomas Reeves
Commercial Director · Sydney, Australia

"I had read about AI for two years and felt informed but stuck. This gave me the first clear next step I had had in months. I took the assessment on a Sunday and had a plan by Monday."

Emma Walsh
VP of Product · San Francisco, USA

"I expected another personality test. What I got felt more like a proper review of my role. The read on how exposed I am was uncomfortably accurate, and the plan laid out the steps in the same order my team had already been arguing about for months."
