Research Interests

Our nervous system is continually changing during development, aging and in chronic diseases such as neurodegeneration. Understanding the spatiotemporal dynamics of these changes is at the heart of Neuroscience research. Key questions that drive my research include: 1) How do development, aging and disease progressively alter brain physiology? 2) How do they tune or alter the information processing capacity of the nervous system at molecular, cellular and network levels of organization? 3) How do transcriptional and translational algorithms transform in response to stressors such as disease and aging? We address these multifaceted questions through an iterative combination of theory and experiments. This way, we seek to help identify early biomarkers and therapeutic strategies for devastating diseases, drive adaptive technology development, guide bioinspired computational algorithms and enrich the theoretical framework of Neuroscience.
