Would ideally be a 2 yr commitment. I’ll update this thread with an official link to submit an application (coming soon), but in the meantime please feel free to email me with a CV and cover letter!

The tech would focus on protein-ligand binding, getting experience with biophysical methods such as SPR, ITC, fluorescence spectroscopy, NMR, X-ray crystallography, etc. Would also get experience with computational protein-design tools (though the role is primarily focused on experiments).

I’m looking to hire a research technician for my lab at Harvard & DFCI, who would primarily work in the wet lab expressing and characterizing designed proteins, starting this summer. A great role for a recent college grad looking for an immersive research experience before grad school.

As someone trained in physics, this project really helped me learn the nuances of denoising diffusion models. The β€œtime” variable acts as an alchemical transformationβ€”e.g. RFDiffusion transforms between protein structure and an ideal gas.

Crystallographic Ensembles Reveal the Structural Basis of Binding Entropy in SARS-CoV2 Macrodomain Structure-based drug design has traditionally focused on optimizing static, enthalpic interactions between ligands and proteins or on displacing binding site solvent molecules to entropically favor bi...

New preprint! Entropy drives molecular recognition, yet most structure-based drug design ignores it because it is difficult to measure. X-ray crystallography captures ensembles, not single structures. Can we extract thermodynamically meaningful entropy from them?
