Rate My Professor Ahmed Abdelfattah

The Abdelfattah lab develops molecular tools to visualize and study brain circuits using bioengineering and chemical approaches, integrating electrophysiology, fluorescence imaging, protein engineering, and advanced genetic methods. Research interests include cellular and molecular neurobiology, neuroengineering, and neurotechnology. Key innovations include Voltron, a chemigenetic fluorescent voltage indicator that enables simultaneous imaging of neural activity from dozens of living neurons, now utilized by hundreds of labs worldwide. Representative publications are “Bright and photostable chemigenetic indicators for extended in vivo voltage imaging” (Science, 2019), “Sensitivity optimization of a rhodopsin-based fluorescent voltage indicator” (Neuron, 2023), “A general approach to engineer positive-going eFRET voltage indicators” (Nature Communications, 2020), “The HaloTag as a general scaffold for far-red tunable chemigenetic indicators” (Nature Chemical Biology, 2021), and “Erasable labeling of neuronal activity using a reversible calcium marker” (eLife, 2020). Abdelfattah has earned prestigious honors, including the Searle Scholar Award (2021, $300,000), the NIH Director’s New Innovator Award (2021, $1.5 million over five years), and the Rita Allen Foundation Scholar Award (2022). His contributions advance high-resolution imaging and manipulation of brain activity, supporting investigations into neural circuit function and disorders.
