If you are interested in studying Earth History and/or Geobiology at Harvard, or find a particular aspect of our work interesting, please don’t hesitate to contact us. We are always looking for motivated and interested parties.

Graduate students (through the Department of Earth and Planetary Science), undergraduates, and post-docs are all welcome. We are particularly looking for graduate students in the upcoming application cycle who:

1. seek to interrogate modern microbial metabolisms in an effort to calibrate physiological responses to changing environmental conditions, and

2. are interested in studying Earth history or modern environments with novel isotopic systems

About us,

  1. we no longer consider GRE scores in evaluating an applicant’s capacity to conduct PhD level research.
  2. The average time to complete a PhD in the lab is ~ 5.75 years**
  3. 100% of students starting a PhD in the lab have completed their degrees

As a lab, we encourage individuals from underrepresented groups to reach out. We strive for a fully inclusive and supported work environment and welcome all that are interested in these scientific pursuits. Further, we conduct ourselves following a shared set of expectations to best promote a safe and productive workplace.

Interested students are encouraged to contact Professor Johnston directly.


** We had a crazy flood that shut things down for a while, so we hope this number comes down.
