I came to this country 15 years ago, and it is unbelievable to me that we haven't managed to improve this system even an iota in these years. It is not just a cruel system, it is also self-defeating. Please read this thread and tag your senators. Alex Padilla Senator Dianne Feinstein

I have been thinking about the best approaches for building predictive models in liquid biopsies for many years now! Orion, which was built by the exai bio team with input from our advisors Olivier Elemento and James Zou is the culmination of that effort. medrxiv.org/content/10.110…

Proud of this work and excited about the immense potential of cell-free RNA.

Big thanks to VanBUG and Faraz Hach for the invitation! I had a fantastic time presenting and engaging in the insightful discussions at VanBUG.

Thank you Iman Hajirasouliha for the invitation! I thoroughly enjoyed the engaging and productive discussion with faculty and students at WCM on the development of computational biology and ML approaches for genomics, along with their applications in cancer research.

Check out our recent work on one of the first multi-modal cell-free RNA foundation models for blood surveillance & liquid biopsy!

Always fun to see the "band" get back together! Cheers to former lab members!

This is an incredible progress story An aggressive type of cancer (Philadelphia chromosome–positive acute lymphoblastic leukemia) used to carry a dismal prognosis, with 50% of patients dying in a year New therapies have transformed it to a cancer that most people are cured of

In light of the US government's move to aggressively revoke Chinese student visas, I thought it worth revisiting former slave Frederick Douglass’s moving response to the Chinese Exclusion Act of 1882:

💡IMO one of the best use of AI Scientist is to reanalyze data to find new insights. Introducing #CellVoyager: AI Compbio Agent that makes new discoveries by autonomously analyzing papers/data, which we then validate🚀 New findings on aging, Covid, scRNAseq etc. Open source!

Hannenhalli & Pevzner's legendary STOC-95 paper on sorting by reversals has won the 30-year Test-of-Time Award at STOC! 30 years!! A rare algorithmic gem from #compbio with lasting impact - I still use it to introduce genome rearrangements in my class. sigact.org/prizes/stoc_to…

I wanted to write something about the travel ban... but I realized I can't say much beyond what I had said before. So, I will just re-post this here: the-scientist.com/opinion--broke…
