Nikolaos Biris
Senior Director, Structural and Functional Biology @ Astria Therapeutics, Inc.
About
As Senior Director of Structural and Functional Biology at Astria Therapeutics, I contribute to advancing therapeutic programs by leveraging expertise in structural biology, protein engineering, and antibody engineering. My role is focused on leading cross-functional teams, managing external partnerships, and establishing scientific strategies that align discovery efforts with translational and portfolio objectives. With over 15 years of experience in protein sciences, I specialize in structural biology techniques such as NMR and X-ray, biophysical methodologies like ITC and MST, and assay development. I am committed to delivering compliance-ready, high-quality data to de-risk assets and accelerate their progression to the clinic, while fostering a culture of high standards, reproducibility, and continuous learning.

My efforts focused on investigating protein-protein interactions related to signaling such as the mitochondrial cell death pathway. I explored protein interactions of the BAX protein to decode the mechanism of BAX translocation to the outer mitochondrial membrane (OMM). I also worked on the structure and targeting of proteins related to mitochondrial fusion and fission. For that purpose, I utilized advanced NMR techniques and experimentally driven computational methods coupled with biochemical and cell-based approaches. Moreover, I was involved in several drug discovery and development projects using my expertise in computer-aided screening, fragment-based screening, hit-to-lead design and optimization. For several protein targets, we have identified potent, selective, small molecule inhibitors and activators of signaling pathways with drug-like properties that are validated in animal disease models.
