2025 update because I'm not seeking to hire anyone or sponsor any new students right now. Possible exceptions for people who are *really* allied with my funded work (e.g., on mpox vax, vax misinfo) and/or have access to external funding (e.g., fellowship, home nation). Lab is at capacity for now.

Prospective students: Here's what you need to know if you think you might want to work with me (a thread):

1. I'm not looking to recruit new students at the moment. (There could be some exceptions, especially for research-oriented Master's students in my school or interdisciplinary studies.)

Can you help me understand what you mean when you say the risk stems from a lack of information about alternatives? Whose lack, immigrants or policy-makers? What alternatives are people unaware of or uninformed about?

This one individual's situation notwithstanding, we need to do better by CUETS and similar program newcomers. bsky.app/profile/grey...

Uncertain immigration status puts people in vulnerable positions, with young women at particular risk of being taken advantage of. If staying depends on no arrest record an abusive partner has a lot of power. If spousal status might save your life, ppl may marry sooner than would be advisable.

I know immigration is a hot topic right now & there are loud anti-immigrant voices making it feel unpopular to receive more ppl. But that's beside the point here: giving reasonable security & safety to people who fled war & are already living & working here doesn't change life for Canadians at all.

Renewing the temporary program last year was better than sending people back to a war zone, but it’s inhumane to keep people worrying about that happening when the next temporary permit expires.

Devon Greyson @greyson.bsky.social · 1d

Canada needs to do the right thing & start taking/processing PR applications for CUETS newcomers, probably prioritizing young adults whose lives are indefinitely on hold here and families with children for whom Canada has become home.

Devon Greyson @greyson.bsky.social · 1d

I particularly feel for the young people, who have no pathway to permanency b/c they aren’t established in a “skilled worker” field but also can’t access domestic PSE tuition in Canada. We need to offer a PR path for those who fled war & have been contributing to Canadian communities for 3+ yrs.

Devon Greyson @greyson.bsky.social · 1d

Canada did a good thing w CUETS, giving Ukrainians an expedited pathway to come here when Russia invaded. But it was a temporary program for what turned out to be a not-so-brief war. Now thousands are living in indefinite limbo with no pathway to permanent residency. www.cbc.ca/news/canada/...

FYI for non-Canadians, the Canadian government has just invested in a special, likely one-time, program of prestigious federally funded positions to recruit outstanding scientists to Canada this year.

If you are an info scientist/MLIS+PhD *outside Canada* with a GREAT publication record seeking a qualitative/mixed method postdoc in public health misinformation/pandemic preparedness, I would consider nominating an application to the Canada Impact+ Training Awards. Reach out ASAP; EOI due 1/16.

10 days into 2026 the U.S. has:

• Attacked Syria
• Invaded Venezuela - president arrested
• Deployed ICE - U.S. citizens detained and killed
• Threatens to take Greenland
• Overhauled the childhood vaccine schedule - undermining decades of evidence

This is not normal.
Everyone should be alarmed.

NIH is losing so may good people. First they were fired or RIFd or pressured to retire early.

Now they are leaving because “no longer lend our credibility to an organization that has lost its integrity.”

Proud to know these brave scientists!

The NIH has lost its scientific integrity. So we left

“We can no longer lend our credibility to an organization that has lost its integrity,” write four scientists and administrators who recently resigned from the NIH.

I am honestly shocked at the number of reputable organizations, including even the *Government of Canada*, that continue to support the deepfake porn and CSAM site.

Obviously, this can not replace a trained specialist. I'm hoping someone, though, can take (or has already taken) a stab at quantifying how in/accurate major LLMs are with DNA interpretation, much as has started to be done on other topic areas.

Devon Greyson @greyson.bsky.social · 8d

And, while I'm not a geneticist or LLM expert, I assume these embedded assumptions are also easily lost by a content machine that strings together likely sequences of words.

Yeah. I recognize this is a huge red flag for unmet needs of patients (I observed this in a rare genetic disease community, so patients on the margins for whom personalized info/interpretation may actually be needed) and also YIKES is the LLM actually better than nothing? I honestly don’t know.
