After 10 years, my position at Weill Cornell has officially come to an end at the begging of the month. I am so grateful for the amazing people who spend time in my lab during the last decade and extremely proud of their work.

I feel extremely grateful to have been part of our amazing parasitology community for the last 25 years and for the many friends, collaborators, and colleagues I met along the way. ♥️

The government shutdown and the administration’s continued antipathy towards higher education and research, especially on infectious disease & global health, have severely limited the chances for funding here.

While Weill Cornell has always been supportive during my time there, this meant that there was no bridge funding available from the university and as an Associate Professor I didn’t yet have tenure at Cornell.

Unfortunately, my grants ran out right while Weill Cornell Medicine had a $100M annual deficit followed by Trump’s subsequent suspension of NIH & NSF payments to Cornell.

None of this would have been possible for the amazing mentorship over the last 25 years from @VernCarruthers, @LlinasLab, @deitschkirk, and many others.

I came to the US as an exchange student when I was 16 and have been here ever since. Finally got my citizenship earlier this year, so at age 47, I got to vote for the first time today. #immigrantstory

As standard screens for new antimalarials yield diminishing new targets & chemotypes, GSK Tres Cantos used media that mimics nutrients in serum & found many new hits. We then id'ed the targets and, amazingly, all 29 new chemotypes block PSAC!🤯 shorturl.at/dCCO8

Great collaboration between @GSK Tres Cantos, @WeillCornell and the Sanders Tri-I Therapeutics Discovery Institute. Co-led by Irene Molina at GSK and @RPMansell in @KafsackLab.

Are the @veupathdb blast servers down? Simple searches that normally take seconds, are still running after 5-10 min.

Malaria parasites have multiple 47S ribosomal RNA genes that differ in length, sequence & expression. Our @WeillCornell ACCESS Summer Student Hermela Samuel & @Riward found that their promoters have very really different responses to RNA Pol I inhibitors 🤯biorxiv.org/cgi/content/shor…

Working on some more community love on this gentle Sunday by writing a tutorial on how I use Primer3Plus.com to generate reliable primers for both detection and cloning. Please RT and share with your students! Enjoy! 💚 binomicalabs.notion.site/PCR…

It appears #NIAID will shutter the genome data base we all use daily. This strikes me as a significant mistake that may well endanger much of our global progress. @BSPparasitology @AS_Para @ASTMH @TrendsParasitol @AmSocParasit @parasitesrule @PiParasitology
