Gabriel  Kreiman, PhD

Department: Ophthalmology
Research Centers: F.M. Kirby Neurobiology Center
Hospital Title: Assistant in Ophthalmology
Academic Title: Assistant Professor, Harvard Medical School
Research Area: Computations in the brain and the functional architecture of neuronal circuits

Research Overview

The intricacy of the neuronal circuitry makes the brain the most complex and fascinating system ever studied by Science. The Kreiman lab is interested in understanding how biological networks encode, process and transmit information. There are two main lines of research in the lab: (i) how circuits of neurons represent visual information and (ii) how gene expression is orchestrated, with a particular emphasis on gene expression in the nervous system. The lab uses a combination of mathematical, computational and experimental tools.

The Kreiman Lab combines high-resolution neurophysiology of the human brain and computational models to understand the processing of visual information--from perception to cognition.

About Gabriel Kreiman

Gabriel Kreiman received his MSc and PhD degree from the California Institute of Technology (Caltech) and subsequently worked as a research fellow at the Massachusetts Institute of Technology (MIT). The Kreiman lab is interested in the neuronal circuits and algorithms responsible for visual object recognition and memory formation. Visual object recognition is crucial for most everyday tasks including face identification, reading and navigation. The Kreiman lab combines neurophysiology, psychophysics and theoretical/computational modeling to understand the neuronal circuits, algorithms and computations performed by the visual system and to develop biophysically-inspired computational approaches to machine vision and memory formation.
