Biomolecular Big Data Languish
LABOR-INTENSIVE DATA ANALYSIS PLANS are slow to develop and expensive to
execute.
MANY DATA SOURCES
are not integrated.
BIOINFORMATIC EXPERTISE
NEEDED to navigate complex
biomolecular big data.
LIMITATIONS OF PUBLISHED
RESULTS
Hypothesis-driven analyses don’t
anticipate many future uses.
FAILURE TO INFORM
ONGOING MEDICAL
RESEARCH
Data are not revisited in new contexts.
DIVERSE DATA gene expression

+
DISCONNECTION
Many big data details are not related to medical research concepts, which
discourages efforts to re-use.

What Is Knowledge Synthesis? Services Customized Data Analysis, Discovery Research, and Technology. Underexploited data means missed opportunities. Knowledge Synthesis will increase your return on investment by reducing data to findings that inform your actions. We integrate all types of life sciences data. We build databases, search interfaces, and data analysis tools and pipelines. We also use the technology we build and can work with your research team to get the results you need to make decisions for better medicine. Products in Development: iDataMed and Pathway Data Analytics Big Data for every life sciences investigator. With iDataMed, Knowledge Synthesis meets the challenge to tame Big Data for life sciences researchers. The key is to bring data into the right context to forge new biomedical knowledge. Straightforward text searches bring the right biomolecular findings to the right person at the right time. Pathway Data Analytics conveys pathway analysis details without compromising understandability. By using intuitive data visualization, we provide easier to navigate pathway analysis. Technology Breadth and depth for every study. Our proprietary life sciences data integration platform ensures that each data set is viewed through many facets of biological knowledge, including multiple sources of pathways and networks that link genes, proteins, and chemicals. Add to that breadth our ability to normalize statistically significant findings across multiple studies, and your understanding of cells, model systems, and clinical samples gains depth.
