Division of Health Cyberinfrastructure

The Division of Health Cyberinfrastructure (CI), an SDSC Center of Excellence, has developed an extensive portfolio of managed information technology (IT) and data services in healthcare for the UC system, academia, and state and federal agencies. Launched under the brand Sherlock, the four major services include: Analytics, Case Management, Cloud, and Data Lab. The Health CI Division and its services provide a solid and secure foundation and exceptional results for a vast array of healthcare projects in which it serves as the lead or co-collaborator. For more information concerning the Health CI Division’s services and/or projects, please visit



Sherlock Analytics is founded on providing knowledge based on factual data.  This foundation yields better decisions, as users of Sherlock Analytics can base their course of action on knowledge gained from the factual data derived from an intricate analysis as opposed to relying solely on experience or instinct.  The Sherlock Analytics Team supports users through its extensive experience building algorithms, case management software, and reports that encompass users’ needs and requirements. Sherlock Analytics harmonizes data and minimizes the challenges associated with users’ review and analysis.  The Sherlock Analytics Team also recognizes that good business intelligence tools are necessary to accommodate all users of varying degrees of technical savviness; therefore, it creates capabilities, platforms, and tools that allow any user to benefit from their utility. 

Case Management

Sherlock’s Case Management solution integrates best-of-breed, proven commercial off-the-shelf (COTS) technologies and develops these technologies as needed to meet organizational needs. Our approach is to employ COTS Customer Relationship Management (CRM) software and tailor it to provide the user interfaces, data interfaces, and workflows needed to meet unique project requirements.  Accordingly, the Sherlock Case Management team delivers transactional, analytical, and engagement features to support complex, multi-constituent workflows and data interaction. It standardizes and automates information across multiple data sources effectively, efficiently and responsively. The solution supports full-event historical reconstruction, capturing all actions and decisions from case inception to closure, and quantifying the results. Using the Sherlock Case Management framework, users benefit from increased productivity, better collaboration, easier access to information relevant to their case, more timely information delivery, and simplified reporting.

Compliant & Secure Cloud

The Sherlock Cloud infrastructure was established as means to provide secure data storage and computing to academic, state and government partners. Sherlock Cloud is both HIPAA and FISMA compliant and was developed in accordance with hundreds of NIST controls governing system access, information control, and management processes. Sherlock Cloud addresses federal Cloud First requirements and is undergoing FedRAMP Infrastructure as a Service (IaaS) Cloud Service Provider (CSP) certification, a requirement for many new and existing federal contracts and grants.  Sherlock Cloud offers a flexible and scalable compute and storage platform for a variety of research and data projects requiring a secure, access-controlled environment.

Sherlock Cloud’s resources are physically located within the SDSC’s Data Center, and, where needed for redundancy, in a secure data center in Northern California. SDSC’s Data Center is staffed around the clock and protected with controlled access systems, backup power, advanced fire suppression systems, and other safety measures. Sherlock Cloud systems interconnect with a 10Gb/s (gigabits per second) network fabric within the SDSC Data Center, and wide-area networking utilizes more than 100Gb/s of high-bandwidth connections to the Internet and research networks such as Internet2, National Lambda Rail (NLR), and the Corporation for Education Network Initiatives in California (CENIC).

Data Lab

The Sherlock Data Lab helps transform digital data into meaningful information using a hybrid approach to data warehousing that includes both a top-down and bottom-up design. The framework provides data integration capabilities, allowing data to be captured, rationalized, homogenized, and managed using best practices and standards. This includes dynamic mappings, transformations, and master data management techniques utilizing established governance methodologies, with specific focus on data quality and metadata management.  The framework leverages mature and industry leading ETL and integration products. It is aligned with the customer level of data maturity to provide consistent and trusted data for operational data analysis, while enriching with reference data for industry related codes, prices and geographic tagging.
