Associate Computational Scientist- Pharmacological Sciences
About The Position
The Associate Computational Scientist will assist laboratory personnel in computational studies aimed at elucidating the kinetic and thermodynamic mechanisms by which ligands with varying efficacies, including positive allosteric modulators (PAMs) regulate the activation and signaling of G protein-coupled receptors (GPCRs), with particular emphasis on the μ-opioid receptor. The research combines long-timescale molecular dynamics simulations, adaptive sampling, enhanced sampling techniques, and Markov state modeling (MSMs) to characterize transient conformational states and quantify ligand-dependent transition pathways that are inaccessible to experimental structural biology alone. The project integrates computational structural biology with cryo-electron microscopy to determine how allosteric modulators alter receptor activation kinetics, signaling efficacy, and receptor-transducer interactions. These mechanistic insights will guide the rational discovery and optimization of novel PAMs that enhance therapeutic efficacy while minimizing adverse effects, thereby accelerating the development of safer analgesics and other GPCR-targeted therapeutics. The position will also contribute to (a) the development of generative deep learning frameworks for GPCR dynamics that infer collective variables and conformational landscapes from molecular simulations, enabling efficient sampling of receptor activation pathways and predictive modeling of signaling kinetics, and (b) the training and application of large language models using real-world data.
