Packard Fellow and Johns Hopkins University scientist Dr. Jasmina Wiemann is working to understand how living organisms respond to planetary change by developing innovative ways to read molecular “memories” preserved in ancient organisms—helping fill some of the blank pages in the history of life.

12/12 What's clear: we handicap ourselves by studying organisms in environments dramatically simpler than where they evolved. What other fundamental discoveries await scientists willing to bring ecology into the lab?
