I recently left @DbrxMosaicAI to join @flourishailabs.

Why did I decide to make the jump?

I believe that some of the most interesting problems in science might now be within reach. With all the wild advances in AI, there’s no better time to pursue the big questions.

Flourish is doing just that. We are a mix of AI researchers, engineers, and neuroscientists tackling one of the most ambitious problems in the field: human-level intelligence and learning with human-level efficiency.

I have immense respect for the founders @TRReardon , Robert Williams, @jovo, @_vishar and for the team - many of whom built CTRL-labs from the ground up.

I really loved my time at @databricks and MosaicML before that. The caliber of the people and the research is sky high, and I am incredibly proud of the work we did over the past 5 years. In particular I’d like to thank my mentors @jefrankle , @mcarbin and @bemikelive, as well as the cracked @DbrxMosaicAI team.

If you’re interested in working at the intersection of AI research and human intelligence, don’t hesitate to reach out.
