Gabriel’s New Beginnings

Davera Gabriel, Senior Nurse Informaticist, will begin her new role on the HIMSS Interoperability and Health Information Exchange (HIE) committee for FY 20/21, where she hopes to leverage her “boots on the ground standards and data harmonization implementation experience to support HIMSS’ efforts to bridge the data divide between the healthcare and clinical research enterprises it serves, to maximize benefits of interoperable data envisioned for Learning Health Organizations.” See the HIMSS website for additional information.

Davera has joined Johns Hopkins University as a Senior Research Terminologist at the Institute for Clinical and Translational Research (ICTR).  Working under the direction of Clinical Research Information Officer (CRIO), Dr. Christopher Chute, Davera will have broad responsibility for organizing biomedical ontologies, terminologies, and classifications in computable form on terminology servers to serve the requirements of data science and translational research for the Johns Hopkins CTSA, the NCATS Center for Data to Health (CD2H), NCI Center for Cancer Data Harmonization (CCDH), the NCATS Translator grant program and other ICTR partner initiatives.

“I could not be more pleased with this opportunity to bring a translational research perspective and ‘on-the-ground’ data harmonization experience to national initiatives which seek to leverage the impressive emergence of the HL7 Fast Health Interoperability Resources (FHIR) to realize the benefits of a Learning Health Ecosystem” said Ms. Gabriel.  “The experience and insights I gained from working on clinical trials at-scale at the DCRI is a key and invaluable component of the knowledgebase needed to provide data services that bridge remaining gaps between wet lab science to clinical care to public health research and other health discovery initiatives.  In my new role, I am looking forward to continued work with the Duke Center for Health Informatics and Trial Innovation Network colleagues to advance the great promise that Translational Clinical and Bioinformatics offers to improve human health.”


Stead Recipient of Duke 2019 Distinguished Alumnus Award

In the late 1960’s at Duke University, William Stead, MD was a medical student on a research team headed by W. Ed Hammond, Phd,  a new professor in  the Division of Biomedical Engineering at Duke.  They, with the rest of their team, created one of the first electronic medical records in the U.S., The Medical Record (TMR). Fifty years later, Dr. Hammond still teaches at Duke and Dr. Stead is a Professor of Biomedical Informatics and Medicine, and the Chief Strategy Officer of the Department of Biomedical Informatics at Vanderbilt University. The two are good friends and have shared numerous milestones in Informatics in the past 50 years.  When the most recent Duke University School of Medicine Distinguished Alumnus Award was presented to Dr. Stead in November 2019, Dr. Hammond was by his side.

William (Bill) Stead, AB’70, MD’74 has throughout his career worked to further the adoption of information systems in the field of medicine.  He began working in Informatics before there was such a discipline and has been instrumental in shaping how universities create a new generation of medical informaticists. He is a member of and has chaired numerous informatics committees and boards, has received the American Medical Association (AMIA) Morris Collin lifetime achievement award, was a leader in the creation of AMIA, and the inaugural recipient of a leadership award created in his name.   Here is the link for additional information.

Gabriel appointed to HIMSS Interoperability & HIE Committee for FY 20-21

DCRI Senior Informaticist Davera Gabriel has been selected by HIMSS for a two year appointment to the Interoperability & Health Information Exchange (I&HIE) Committee.  The purpose of the committee is to promote standards-based interoperability and new information technologies for secure and accessible health information exchange that leads to improving care while lowering costs. The committee supports HIMSS’ activities on both national and global levels.

In her role, Davera hopes to leverage her “boots on the ground standards and data harmonization implementation experience to support HIMSS’ efforts to bridge the data divide between the healthcare and clinical research enterprises it serves, to maximize benefits of interoperable data envisioned for Learning Health Organizations.” See the HIMSS website for additional information.

The course, taught by Dr. Ed Hammond, DCHI Director, focuses on data representation that is essential for interoperability and the sharing and intellectual use of data across the health care spectrum. The course investigates the current world of healthcare data representation –controlled terminologies such as SNOMED-CT, LOINC, ICD10, RxNorm, DSM-5, MedDRA, CPT, and MeSH; ontologies as a data representation; existing common data element sets; and attributes to make the data element provide meta knowledge. The course also focuses on data transport standards, including HL7 International standards; Standards Developing Organizations such as IEEE, X12, ASTM, NCPDP, DICOM, IHE, ISO TC 215, CEN TC 251; and standards such as Clinical Decision Support standards, Genomic standards, and SMART app standards.

Healthcare Data Scientist Qualifications, Skills, and Job Focus: A Content Analysis of Job Postings

Melanie A Meyer

Journal of the American Medical Informatics Association, Volume 26, Issue 5, May 2019, Pages 383–391,

Published: 01 March 2019



Growth in big data and its potential impact on the healthcare industry have driven the need for more data scientists. In health care, big data can be used to improve care quality, increase efficiency, lower costs, and drive innovation. Given the importance of data scientists to U.S. healthcare organizations, I examine the qualifications and skills these organizations require for data scientist positions and the specific focus of their work.

Materials and Methods

A content analysis of U.S. healthcare data scientist job postings was conducted using an inductive approach to capture and categorize core information about each posting and a deductive approach to evaluate skills required. Profiles were generated for 4 job focus areas.


There is a spectrum of healthcare data scientist positions that varies based on hiring organization type, job level, and job focus area. The focus of these positions ranged from performance improvement to innovation and product development with some positions more broadly defined to address organizational-specific needs. Based on the job posting sample, the primary skills these organizations required were statistics, R, machine learning, storytelling, and Python.


These results may be useful to organizations as they deepen our understanding of the qualifications and skills required for data scientist positions and may aid organizations in identifying skills and knowledge areas that have been overlooked in position postings.
