SUMMARY

Obtaining a second PhD, such as in computer science after already earning one in pure mathematics, is generally considered unnecessary and inefficient. While there are exceptions in fields like medical physics, where individuals may pursue additional qualifications, most professionals opt for post-PhD certificates or master's degrees instead. The primary value of a PhD lies in developing independent research skills, which do not require repetition through a second doctoral program. More efficient alternatives exist for gaining in-depth knowledge in a new field.

PREREQUISITES
  • Understanding of PhD program structures
  • Familiarity with the fields of pure mathematics and computer science
  • Knowledge of alternative qualifications like post-PhD certificates
  • Awareness of professional requirements in specialized fields like medical physics
NEXT STEPS
  • Research the benefits of post-PhD certificates in various fields
  • Explore the role of interdisciplinary skills in career advancement
  • Investigate alternative educational pathways for transitioning between disciplines
  • Learn about the job market demands for PhD holders in computer science
USEFUL FOR

Academics considering additional doctoral studies, professionals in transition between fields, and individuals evaluating the value of advanced degrees in their careers.

Say you have a PhD in pure mathematics but want credentials for computer science for some reason where it might be necessary (is there such a situation?). Is it a waste of time to also get another PhD in computer science?

Generally speaking, yes.

An exception might be for professional cases. In medical physics it's not uncommon for people with PhDs in other branches of physics to go through a medical physics graduate program, but I've never seen anyone go through with a second PhD. Usually they either get a post-PhD certificate or a master's degree - enough so that they can go on to enter the profession.

A PhD is largely about learning the skills to research independently. Once you have those, repeating that training is just an exercise in futility. The other thing you get is an in-depth knowledge of a particular field, but there are more efficient ways to get that if that's all you're lacking.
