I asked a Harvard postdoc a bunch of questions. These are the key takeaways:
:blobcoffee: The fundamentals still matters: math, statistics, coding & logic.
:blobcoffee: We need critical thinking & abstract reasoning.
:blobcoffee: Combining two disciplines leads to exciting projects and connections we couldn’t even imagine before.
:blobcoffee: A stay abroud is often an experience that changes more than our CV - they leave a mark in our mindset.
:blobcoffee: Two days in a postdoc's life rarely look exactly the same: Writing papers, training AI models, giving talks at conferences or running project meetings.
:blobcoffee: Success in research is more like a marathon with long phases without immediate feedback or visible success
