Bionet Group Researchers
Aurel A. Lazar has been a
professor of Electrical Engineering at Columbia University since
1988. He founded the Bionet Group in 2003. His research interests are in computing with neural circuits (in silico), and on reverse engineering the fruit fly (Drosophila melanogaster) brain (in vivo and in silico).
In silico, his research focus is on Neural Computing Engines and NeuroInformation Processing Machines.
In vivo, his research focus is on Reverse Engineering the Fruit Fly Brain.
In 2011 he initiated Neurokernel, an open source platform for the emulation of the fruit fly brain, and in 2014 NeuroArch, a database for querying and executing fruit fly brain circuits. He is currently leading the Fruit Fly Brain Observatory, a worldwide collaborative effort among experimentalists, theorists and computational neuroscientists with the goal to create an open platform for the emulation and biological validation of fruit fly brain models in health and disease.
