Hello everyone, I am looking for my next role in the computational chemistry/biophysics space 🛫 I have 12 years of research experience in protein simulations/SBDD, looking for national lab/industry scientist positions anywhere in the world. Any connections/leads welcomed - thanks in advance! 🙏🏻

Paper was rejected today! Scanning through the reviews, there were some factual/scientific errors that need to be corrected before it can be published 😱 Happy that peer review caught this, would much rather publish a better paper later than rush one out with errors

The war on science in the US is already having an effect on private sector research like AlphaFold. Bears repeating but the private sector builds on top of things created by academic research for the public good. This hurts everyone.

Some crystal structures show evidence of multiple stable conformations, such as loops or side chains with two distinct regions of density. These can be correctly modeled by MD, but not modern protein ensemble prediction tools like AlphaFlow or DiG (BioEmu not tested) www.biorxiv.org/content/10.1...
Examples of alternate conformations with environmental explanations.
(A) a protein in two states (open and closed) mediated by allosteric effects; (B) a population of two discrete rotamer states of a sidechain; (C) bound and unbound states due to ligand interaction; (D) different oxidation states of a cysteine pair. Furthermore, some regions in many protein structures exhibit such a degree of flexibility, that no accurate modelling is possible (dashed lines, E). The backbone conformation cannot be determined with crystallographic methods in such cases.Failure of ensemble prediction algorithms in altloc segments.
Although structure and ensemble prediction techniques based on amino acid sequences are capable of accurately reconstructing the overall backbone structure (left column), they consistently fail to produce viable samples corresponding to one of the two altloc conformations (as shown in the magnified regions in the second through fourth columns).

Everything is chaos, but I wanted to share some awesome recent science from the lab that hints at where the future of biomolecular simulation is headed: Foundation simulation models that can be fine-tuned to experimental free energy data to produce systematically more accurate predictions.
Figure 1 from arXiv preprint https://doi.org/10.1101/2025.01.06.631610

Fig. 1 Espaloma is an end-to-end differentiable molecular mechanics parameter assignment scheme for arbitrary organic molecules. Espaloma (extensible surrogate potential optimized by message-passing) is a modular approach for directly computing molecular mechanics force field parameters FFF from a chemical graph G such as a small molecule or biopolymer via a process that is fully differentiable in the model parameters FNN. In Stage 1, a graph neural network is used to generate continuous latent atom embeddings describing local chemical environments from the chemical graph. In Stage 2, these atom embeddings are transformed into feature vectors that preserve appropriate symmetries for atom, bond, angle, and proper/improper torsion inference via Janossy pooling.54 In Stage 3, molecular mechanics parameters are directly predicted from these feature vectors using feed-forward neural networks. This parameter assignment process is performed once per molecular species, allowing the potential energy to be rapidly computed using standard molecular mechanics or molecular dynamics frameworks thereafter. The collection of parameters FNN describing the espaloma model can be considered as the equivalent complete specification of a traditional molecular mechanics force field such as GAFF38,39/AM1-BCC55,56 in that it encodes the equivalent of traditional typing rules, parameter assignment tables, and even partial charge models.

CDR3 loop conformation, specifically whether the C-terminus is kinked or not, is a major determinants of whether a nanobody-antigen complex is correctly predicted using SOTA protein structure prediction software doi.org/10.1021/acs....
Nanobodies with extended CDR3 conformations are correctly predicted the majority of the time, whereas kinked CDR3 conformations are rarely correctly predicted

Let’s stop treating "leaving academia" as negative. Scientists train for academia, industry, or what suits them. Industry isn’t an alternative; it’s a choice. In fields like engineering, most PhDs go to industry, and no one calls it "leaving academia." We should train scientists for diverse paths.
