If I could redo my PhD

Intelligence isn't a fixed label the universe stamped on your forehead at birth and laminated—it's a muscle, and research is just one more thing you get less bad at by doing it badly, in public, for an embarrassingly long time. Heads up: your taste will sprint out ahead of your skill and then turn around to judge you. You'll be able to diagnose, in forensic detail, exactly why your own work is mediocre long before your hands can do anything about it. That gap isn't a sign you don't belong. It's the engine. (It's also extremely annoying.) Keep going until your hands catch up to your eye.

Don't burn so much fuel on what other people think of you. Whatever verdict they're forming is on a rough draft anyway—they're reviewing an early cut while you've already rewritten the whole thing. And I say this with enormous love: nobody is thinking about you nearly as much as you'd hope or fear. Everyone is the harried lead of their own feature-length production, frantically learning their own lines, convinced the spotlight is on them. The audience you're agonizing over is, at this exact moment, mostly squinting at its phone wondering if that last text came across weird.

Make peace with where you are right now—it's a stage, not a verdict, even when the verdict feels like it's been read aloud and notarized. Progress is slower and lumpier than literally anyone admits in their tidy little success story, and today's version of you is just a rough draft of tomorrow's, typos and all. So do your best in the moment and let the rest unfold instead of trying to storyboard your entire life in advance like a maniac. You're not behind. You're in progress.

First, the reassuring part: most advisors are decent people who want you to do well, and a good one is among the best things about a PhD. This list is mostly for telling a merely overcommitted mentor from a genuinely poor fit — and for spotting the rare exception before you've signed on for years. So: scout the academic elite — the top-tier professors who bring prestige, momentum, and ideas that make you sit up straighter. The catch nobody prints on the brochure is that the most dazzling are often dazzling precisely because they've said yes to everything, which can leave the time for you looking like a calendar invite that keeps getting moved. Prestige is wonderful. Prestige that answers your emails is better.

Take a peek at where their work actually lands. Top-tier journals, or a quiet graveyard of proceedings nobody cites? A strong track record tells you two encouraging things: they can clear the bar you're hoping to clear, and they know the game's unwritten rules well enough to teach them. You want your ambition pointed at someone whose ceiling sits comfortably above your floor.

Do they co-author with their students? A great sign — but don't stop at the byline. A shared name can mean a true partnership, or, occasionally, that a supervisor added themselves to work that was mostly the student's; co-authorship norms are loose, and a name is easy to add. So read a few recent papers and look for where the student actually led — a method they built, a section that's clearly theirs, a real idea of their own. When you can see students driving the work, it's a lovely signal about how this person shares credit. When you can't, it's just one more thing to weigh.

Have they pulled in real research money — the competitive kind, where strangers read the idea itself and decided to wager real budget on it — or is the CV mostly smaller awards and commissioned work? Both are completely legitimate; they just signal different bets: peers on the question, or a funder on the activity. And funding, like authorship, usually has more hands behind it than the headline names — worth remembering that any CV is a story someone curates, not a neutral ledger. Read it as one, generously.

And yes — conduct a respectful, scholarly Google stalk of their collaborators. (Everyone does this; we just don't admit it at parties.) Who someone chooses to work with tells you which rooms they're invited into, and an advisor in good rooms can, eventually, hold a door open for you. You're not just picking a person — you're marrying into an academic family, in-laws and all.

And notice whether anyone works with them twice. One co-authorship means two people were once in a room together; a repeat co-authorship means the first time was good enough to do again. The warmest reference a collaborator ever gives is the second paper — people come back for the good ones. A short list of long partnerships says one thing; a long roster of one-and-done names says another. Neither is damning on its own, but the pattern is quietly informative, and it's the one you can actually see.

Career stage matters more than the title lets on. A senior advisor brings gravity, stability, and a contacts list three decades deep — and, sometimes, a schedule so fragmented you'll come to know them mainly through their out-of-office replies. A junior advisor is often hungrier and more hands-on — and also running their own white-knuckle sprint toward tenure, which makes their attention a renewable but genuinely scarce resource. Either can be wonderful. The real question is never just how impressive someone is — it's whether they have the bandwidth and the genuine desire to mentor someone who isn't them.

If you want to work on real problems, resist the urge to spend an entire career inside one disciplinary silo. The good stuff tends to live in the gaps between fields—the unclaimed territory where the methodology police haven't set up checkpoints yet. Most of the best ideas arrive sideways: you're staring at one problem and a completely different one falls out of your pocket.

Start with good sources, and define "good" generously. Serious investigative journalism counts—reporters often map a problem years before the literature catches up. And don't sleep on the grey literature: think tanks, policy institutes, advocacy shops. Some of it is special pleading dressed as research, sure, but buried in there are datasets, field reports, and questions that will never reach a journal—because nobody gets tenure for them, not because they aren't worth asking.

Train yourself to think across fields, because the borders are far more porous than the departmental org chart pretends. A tool built for one problem is often quietly perfect for an unrelated one:

• Health-insurance math—pricing rare, expensive events—is also flood-risk math; a hospital stay and a flooded basement are the same actuarial animal.

• The industrial-organization toolkit, built to dissect markets and market power, untangles an agricultural supply chain without breaking stride.

• Sociology keeps handing you the variable that actually matters, even when it's cheerfully agnostic about what caused it.

• A jump in environmental sensing—satellites, cheap sensors—quietly rewrites how some field with nothing to do with the environment collects its data.

And go to the talk in the other department—yes, the one you have no business attending. You won't follow every slide, and that's fine; that's half the point. You'll leave with a new way of seeing your own problem, or at minimum a better question than the one you walked in with. A better question is never a wasted afternoon.

Actually engage with the thing, even when the thing has the narrative momentum of drying paint. Sit with the argument instead of skimming past it, and watch which ideas make the room lean forward and which quietly die the moment someone pushes back. That second category is its own kind of data: a concept that can't survive one hard question is telling you something.

Whoever you are, take up the space. Ask the question—even the one you're sure is too basic, especially that one, because half the room is quietly wondering the same thing and only the bravest person says it out loud. Visibility isn't vanity; the people who get remembered are simply the ones who were in the conversation. You don't need to be the smartest voice in the room. You need to be a voice in it.

Don't panic when half of it sails over your head in real time. Experts skip steps—not to lose you, but because the thing they're skipping has been obvious to them for fifteen years and they've forgotten it was ever hard. The gap between "I didn't follow that" and "I'm not smart enough for this" is mostly just the steps they left out. Fill them in afterward; that's where the real learning lives anyway.

And breathe. Everyone in that room felt exactly this lost at some point, including the person at the front pretending they didn't. The work is long and lumpy and occasionally absurd, and the people who make it through aren't the ones who never struggled—they're the ones who kept their sense of humor about the struggling. Don't leave yours at the door.

And while you're there: scout. Every seminar is a low-stakes audition reel for future mentors, collaborators, and the speaker you'll email next week saying "I really enjoyed your talk." Expanding your circle isn't a cynical side quest—it's half of what the room is for. Sit near someone interesting. Say hello after. That's the whole technique.
