Keith Vossel

Keith Vossel’s laboratory studies mechanisms and novel treatments for seizures and associated memory loss in Alzheimer’s disease. Investigations include cell and molecular, neural network, and behavior relationships in mouse models of Alzheimer’s disease and related dementias, and bridges bench discoveries with human clinical trials.

Daniel Aharoni

Dr. Daniel Aharoni has a background in equipment design, test and measurement systems, data analysis, and product development. His work focuses on bridging the gap between specialized tool design and the intricacies of modern neuroscience. By applying design methodologies from engineering and physics, the Aharoni laboratory develops specialized neuroscience research devices to addresses open questions in the field. This group leads the development of the UCLA Miniscope project and builds other tools with an emphasis on i) neural recording techniques for freely behaving animals and ii) open-source dissemination of novel technology. Through innovation and optimization, this work aims to extend the reach of neuroscience and train the next generation of research driven tool developers.
