Dear Jeff
I've been on the road and in meetings literally since leaving your house [sic] yesterday

Best regards,

dear jeff:
thanks for the kind words. i enjoyed meeting you; i had not known you were connected to john brockman, but i should have guessed!
as luck would have it, i am slated to be in NYC this coming thursday for a dinner and could meet before that, any time between 2 and 5, if that happened to work for you. otherwise, i could surely come back again within the coming weeks.
my lab has a number of foci at present: 1) the evolutionary biology and genetics of social networks and social interaction; 2) the experimental exploration, using online tools, of network structure and function in humans (how does network structure affect phenomena like cooperation, innovation, health, etc.); and 3) randomized controlled trials in the developing world of network 'targeting algorithms' aimed at enhancing spillover effects, so as to facilitate population-level behavior change by identifying and targeting influential people.
let me share three papers with you (one unpublished) that flesh out some of our work (specifically [1] and [2] above):

There's no ICE accountability without ending qualified immunity.
They're murdering people. There won't be justice for the lives they've stolen, but there must be accountability.
My bill with @markey.senate.gov would ensure families can sue the agents murdering their loved ones.

Some news: Harvard is the 8th institution to receive a gift for theoretical physics from the Leinweber Foundation. We're excited to have a new, stable source of support for PhD students and postdocs, at a time when young researchers have been especially anxious about careers in science in the US.

Interesting to see Jeffrey Wigand's name in the discourse. To me, he was the 9th grade science teacher who took a class full of kids excited about science and did his best to make us hate it. Gave us challenging assignments with no explanation and refused to even point us to a book. 1/

Love when we order delivery from a restaurant, our food never arrives, the restaurant tells us we have to ask the delivery service for a refund, and the delivery service tells us we have to ask the restaurant for a refund, so we accept the loss and cobble together a quick meal ourselves like chumps.

Just because an urbanist influencer has posted a 6 months old piece (that was anyway inaccurate) about it does not mean it is happening!

Kind of charmed by all the people on here who think Harvard would fire a famous, senior professor for being a terrible person who is wrong all the time, or even for serial misconduct. That’s not the Harvard I know, unfortunately.

Apropos of nothing: Last year, one day I found my path through Harvard Yard blocked by a slow-moving group of a dozen or so students and two econ profs, one of whom was Larry Summers. He was holding forth about how other people's inflation expectations were wrong. 1/

The American people aren't interested in boring process stories like "was the world's most notorious sex trafficker providing underage girls to the President?", they wanted to know more about whether Claudine Gay followed best citation practices for her dissertation.
The emails that you’re seeing now are news in themselves, but that’s because of how they’re coming out—a congressional committee released them—& the context in which they’re being viewed. A guy emailing a reporter talking about old girlfriends or saying someone is “dirty” is not a whole news story.
