David J. Anderson

David J. Anderson is the Seymour Benzer Professor of Biology at the California Institute of Technology (Caltech), serving as Director and Leadership Chair of the Tianqiao and Chrissy Chen Institute for Neuroscience. He is also a long-standing Investigator of the Howard Hughes Medical Institute (HHMI), appointed in 1989.

His academic credentials include an A.B. in Biochemical Sciences from Harvard University (1978, summa cum laude) and a Ph.D. in Cell Biology from Rockefeller University (1983), where he trained with Nobel Laureate Günter Blobel. Postdoctoral training followed at Columbia University with Nobel Laureate Richard Axel.

Anderson's research centers on the neurobiological basis of emotional behaviors, particularly fear, anxiety, and aggression. His lab employs mice, Drosophila, and the jellyfish Clytia hemisphaerica to dissect neural circuits using optogenetics, chemogenetics, single-cell RNA sequencing, and advanced behavioral analysis. Key discoveries include identifying aggression-controlling neurons in the hypothalamus and fear-processing microcircuits in the amygdala.

Recent publications reveal a strong emphasis on decoding aggression circuits through computational modeling of neural dynamics, whole-brain imaging, and cross-species comparisons. His work integrates molecular, cellular, and systems approaches to understand how internal emotional states emerge from neural activity and influence behavior.

Major scientific awards include:

• 2018 Edward M. Scolnick Prize in Neuroscience
• 2017 New York Academy of Medicine Salmon Award
• 2016 Perl-UNC Neuroscience Prize
• 2007 National Academy of Sciences election
• Multiple named professorships and fellowships

As an HHMI Investigator since 1989 and Allen Distinguished Investigator (2010), Anderson has secured substantial research funding. He serves on the Scientific Advisory Board of the Allen Institute for Brain Science and has mentored numerous trainees. His lab develops cutting-edge tools like the Mouse Action Recognition System (MARS) for behavioral analysis.

The David Anderson Lab operates as a multidisciplinary hub integrating genetics, neurophysiology, and computational methods. Current collaborations with engineering groups focus on machine vision for behavior quantification, while expanding the Clytia model to investigate primitive internal states in brainless organisms.
