My first-ever (second-author) publication is now online as a preprint! The “isotopomer project” was as fascinating as it was challenging over the last ~3 years, and it’s great to be able to share the full story. Congratulations to the rest of the team!

Happy Boxing Day to the best team in football… just came across this classic:

@molandergroup You’re still affiliated with Penn Chemistry? How?

[David Polefrone @dpolefrone]

@SuperScienceGrl Interested!

@gutierrez_lab @ChemBiochemUMD @adse_penn Thanks very much :') y'all really are the "real OGs"

[David Polefrone @dpolefrone]

Thrilled to share that I’ve been awarded the NSF Graduate Research Fellowship!

To all my teachers, mentors, coworkers, friends, loved ones along the way, thank you. Your support has made, and continues to make, all the difference.

Do you ever think: What probabilistic ML model is best for my small chem dataset? How does it perform in experiments (ie. Bayes opt)? And how well does it generalise to out-of-distribution molecules?

Check out DIONYSUS (formerly GPmol)! https://t.co/8txqCJe6ov

1/ Excited to share our new paper "Labor advantages drive the greater productivity of faculty at elite universities" in @ScienceAdvances with @hneutr @danlarremore @aaronclauset: https://t.co/nXqEsMipTe

Why do faculty publication rates increase so much with prestige? Let’s go:🧵

@Melt_Dem Despite structural similarity, methamphetamine is much more potent than Adderall (let alone differences in formulation). They’re very much not the same thing; conflating them is irresponsible on several levels

@MingbinYuan Congrats Mingbin, great stuff!

@sksilverman @DirkTrauner Perhaps interestingly, if we were concerned with the ordering of strokes, the same expression/number would work for the possible outcomes when using 6 length-1 strokes

It was great meeting national ADSE board member Professor Steven Lopez today! @StevenLopez_neu @DirkTrauner @KozlowskiMarisa @PennChemistry @ADSE_national

Super excited to share the first project of my PhD published now in @JOC_OL. Many thanks to @b_orzy and the rest of the @KozlowskiMarisa group.

A somewhat autobiographical perspective on programming, data, and organic chemistry, in @ChemistryWorld.

And a hint that soon, I will be starting a new job. 😊

Why do so many experimental chemists distrust computations? And what can we do to fix this? (spoilers: have higher standards, standardize our protocols, and accept the limits of our methods)

Bond by bond Molecular editing of C3-C7 was daunting, to reverse the order looked impossible as we call this Apollo 17 moonshot. In addition to distance and geometry, we used chiral recognition to realize this feat for the first time, @nature
