Welcome to the extraordinary universe of Omics sciences (组学) — where genes, proteins, cells, molecules, biological systems and artificial intelligence come together to reveal the fascinating complexity of life.
From understanding why diseases happen to discovering better medicines, improving food systems and protecting our planet, Omics is changing how we understand and interact with the living world.
Omics refers to a family of scientific disciplines that study the complete sets of biological components within a living organism, cell, tissue or biological environment.
Instead of investigating only one gene, one protein or one chemical at a time, Omics approaches examine large collections of biological information together.
Think of it as moving from studying individual musical notes to understanding an entire orchestra — its instruments, relationships, rhythms and interactions.
The word Omics is commonly associated with the comprehensive study of biological entities, such as the genome (all or substantially all genetic material), proteome (proteins), transcriptome (RNA transcripts) and metabolome (small molecules).
When these different layers are studied together, we enter the exciting world of Multi-Omics.
Explore the different branches of Omics sciences. Each reveals another dimension of life. Select any subject to discover what it studies and why it matters.
Studying the complete genetic material of an organism — its DNA, genes, variations and organization.
Genomics helps researchers understand inherited characteristics, genetic diseases, evolutionary relationships and potential disease risks. Applications include genome sequencing, cancer research, rare-disease investigation, pathogen surveillance and precision medicine.
Investigating the complete collection of proteins produced by a cell, tissue or organism.
Proteins perform much of the work inside living systems. Proteomics examines protein abundance, structure, modifications and interactions. It supports biomarker discovery, drug-target identification, disease research and the study of biological functions.
Studying RNA molecules and understanding which genes are active under different conditions.
RNA provides an important view of how cells use genetic instructions. RNA sequencing and related methods help identify gene-expression patterns, cell responses, disease mechanisms and differences between healthy and diseased tissues.
Measuring the small molecules involved in metabolism and the biochemical activities of life.
Metabolites offer clues about what is happening inside cells and tissues. Applications include metabolic disease research, nutritional studies, biomarker discovery, drug-response assessment and understanding how organisms respond to their environments.
Studying chemical and structural modifications that influence how genes are switched on or off without changing the underlying DNA sequence.
Epigenomic research investigates DNA methylation, histone modifications and chromatin organization. It helps explain how development, ageing, environmental exposures and disease can influence gene activity.
Studying the diversity, abundance and functions of fats and other lipid molecules.
Lipids form cell membranes, store energy and participate in biological signalling. Lipidomics supports research into cardiovascular disease, metabolic health, inflammation, brain function and pharmaceutical development.

Using Omics approaches to investigate the biological effects of chemicals, toxins and environmental exposures.
Toxicomics combines molecular measurements with toxicological studies to identify biological changes associated with potentially harmful exposures. Applications include drug safety, chemical risk assessment, environmental health and early toxicity biomarker discovery.
Studying the observable characteristics and traits of organisms at a large scale.
Phenomics connects observable characteristics with genetics, environment and biological function. It uses imaging, sensors, laboratory measurements and computational analysis to investigate health, disease, plant traits and organismal development.
Investigating metals and metalloids in biological systems, including their distribution, interactions and functions.
Metallomics examines essential elements such as iron, zinc and copper, as well as potentially toxic metals. It contributes to research into nutrition, neurological disorders, cellular processes, environmental exposure and disease.
Extracting large amounts of quantitative information from medical images using computational methods and AI.
Radiomics converts medical images such as CT, MRI and PET scans into measurable features. Combined with clinical and molecular information, it may support tumour characterization, disease assessment, treatment-response prediction and precision imaging. Clinical adoption requires rigorous validation.
Studying the immune system through large-scale analysis of its genes, cells, proteins and responses.
Immunomics investigates immune diversity, antibody repertoires, immune-cell populations and immune responses. It has applications in vaccine development, cancer immunotherapy, autoimmune disease and infectious disease research.
Exploring the microorganisms and their collective biological functions within a particular environment.
Microbiomics studies microbial communities and their relationships with their hosts and environments. It overlaps with metagenomics, metatranscriptomics and microbial metabolomics.
Mapping connections and communication networks within nervous systems and the brain.
Connectomics investigates neural connections at different scales, from individual neurons to large brain networks. It supports research into cognition, brain development and neurological conditions.
Discovering not just what is happening in cells, but precisely where it happens within tissues.
Spatial transcriptomics and spatial multi-omics preserve information about the location of biological activity in tissues. They reveal cellular neighbourhoods, tissue organization, disease microenvironments and interactions between cells.
Other developing and specialized areas include exposomics (environmental exposures), viromics (viral communities), virometabolomics, degradomics (protein degradation), secretomics (secreted molecules), glycoproteomics and single-cell multi-omics.
The boundaries between disciplines are not rigid. Many modern discoveries happen precisely where different Omics fields overlap.
Every Omics discipline contributes another piece of the biological puzzle. Integration helps us move from isolated observations towards a more comprehensive understanding of living systems.
This is a simplified conceptual pathway, not a one-way biological sequence. Biological regulation, environmental influences and feedback mechanisms connect these layers in complex ways.
Investigate one major class of biological information in depth.
Combine several Omics layers to understand relationships and interactions.
