Hogenesch Lab

Circadian Biology • Systems Biology • Circadian Medicine

The Hogenesch Lab studies biological timing across molecular mechanisms, genome-scale transcription, and medicine. The work links core clock architecture to tissue-scale rhythmic programs and to translational questions about when physiology, disease processes, and therapies are most sensitive to time of day.

Research Themes

Five directions of research

Molecular Circadian Clock

Mechanistic work on BMAL1, NPAS2, transcriptional feedback architecture, and clock-controlled gene regulation in mammalian systems.

Circadian Biology

Rhythmic physiology across organs, tissues, and cell systems, including the architecture and outputs of biological clocks.

Systems Biology

Genome-scale transcriptional programs, the mammalian circadian transcriptome, and atlas-level studies of time across tissues.

Computational Methods and Resources

Algorithms and public tools including JTK_CYCLE, PSEA, MetaCycle, CYCLOPS, CYCLOPS2, CircaDB, and Gene Atlas.

Circadian Medicine and Rare Disease

Human transcriptomics, chronotherapy, and published work linking circadian phenotypes to Human Genetics and rare disease, including Smith-Kingsmore syndrome.

Featured Resource

CircaDB

CircaDB is a public database of mammalian circadian gene expression profiles developed by the Hogenesch Lab in collaboration with Andrew Su. The resource allows researchers to explore rhythmic gene expression across tissues and datasets and has become a widely used tool in the circadian biology community.

Published CircaDB query interface.
CircaDB provides direct access to circadian expression data by gene, dataset, tissue, phase, and significance threshold.
