prof. James Smalls.
Frank Wilderson and Jared Sexton, even though I disagree with many of their conclusions... but I just found them a few weeks ago and their shyt is mad thought-provoking.
I wasn't hit to Wilderson III at this time, but I've read Afropessimsim and Red, White and Black and they're fantastic.Sandy Darity at Duke and Darrick Hamilton at The New School are doing some of the most important research on black political economy
Braykeshia Samms and Cherrie Bucknor do good economics stuff as well
As far as critique, check Adolph Reed at UPenn, Michael Dawson at U Chicago, Andra Gillespie at Emory and J Philip Thompson at MIT, and the young nikka R.L Stephens who been setting the internet ablaze with every essay
Also check out Wendi Muse. She's on twitter and does good work on the history of PoC leftist movements
