13. Examples of Growing Synergies
Between Clinical and Bio- Informatics
• Applications at the intersection of genetic and
phenotypic data
– e.g., pharmacogenomics
– e.g., identification of patient subgroups
• Shared methodologies with broad applicability
– e.g., natural language and text processing
– e.g., cognitive modeling of human-computer
interaction
– e.g., imaging (organs, biomolecular, 3D)
– e.g., inferring structure from primary data
– e.g., data mining (knowledge extraction) from
large datasets
14. Journal of Biomedical Informatics
• Formerly “Computers and
Biomedical Research”
• Volume 36 in 2003
• Emphasizes
methodologic innovation
rather than applications,
although all innovations
are motivated by applied
biomedical goals

20. Dental Informatics
• Significant opportunities
for research across the
spectrum of biomedical
informatics application
areas (bioinformatics,
imaging, clinical, public
health)
• Challenges exist that can
help to drive innovation
and scientific
contributions in
biomedical informatics and
in other, non-biomedical,
areas of application

22. Challenges For Academic Informatics
• Explaining that there are fundamental
research issues in the field in addition
to applications and tool building
• Finding the right mix between
research/training and service
requirements
• Developing and nurturing the diverse
collegial and scientific relationships
typical of an interdisciplinary field
23. Academic Informatics:
Lessons We Have Learned
• Service activities can stimulate new research and
educational opportunities
• Need to have enough depth in faculty to span a
range of skills and professional orientations
• Need to protect students from projects on critical
paths to meeting service requirements
• Institutional support and commitment are crucial
–Financial stability
–Visibility and credibility with colleagues in other
health science departments and schools
24. Training Future
Biomedical Informatics Professionals
The Problem:
There are too few trained
professionals, knowledgeable about
both biomedicine and the component
sciences in biomedical informatics
The Solution:
Formal training in biomedical
informatics, with the definition of a
core discipline and specialized
elective opportunities
25. Curriculum Development
Perspective of our Department of Biomedical Informatics
• Basic objectives: fundamental areas of biomedicine,
computer science and mathematics that are
prerequisites for further study in Biomedical Informatics
• Core objectives: essential skills required by all
Biomedical Informatics students
• General objectives: ability to conduct research and
participate in the educational activities of the field
• Specialized objectives: application of general methods
and theories in at least one of four different areas:
bioinformatics, imaging informatics, clinical informatics,
and public health informatics
31. Program Characteristics
Steady-state program size: 45-50 students
– Dental informatics postdocs 3 students
Applications per year: ~130 candidates
Admissions per year: 8-10 students
Principal faculty: 30
Participating and consulting faculty: ~20
Trainees generally supported on a training
grant, as graduate research assistants on
sponsored projects, or as teaching assistants
32. Doctoral Research in Informatics
• Although they are inspired by biomedical
application goals, dissertations in biomedical
informatics must:
–offer methodological innovation, not simply
interesting programming artifacts
–generalize to other domains, within or
outside biomedicine
• Inherently interdisciplinary, biomedical
informatics provides bridging expertise and
opportunities for collaboration between
computer scientists and biomedical
researchers and practitioners
33. Career Paths for Biomedical
Informatics Professionals
• Academic biomedical informatics research and
development, and educational support
• Clinical, administrative, and educational
management
• Operational service management
• Health system chief information officer or
medical/nursing director for information
technology
• Digital library development and implementation
• Corporate research and development
• Biotechnology/pharmaceutical companies
34. Trends
• Creation of several new biomedical informatics
departments or independent academic units
• Reasonably strong job market for graduates of
informatics degree programs
• Government investment in training and research is
reasonably strong, especially for applications and
demonstrations
• Increasing acceptance of biomedical informatics as
an emerging subspecialty area by biomedical
professional societies
• Increasing recognition that biomedical problems can
drive the development of basic theory and
capabilities in information technology research
