Science Drivers Over the
Millennia

5. The Human Genome was the Tipping Point
and Led the Way
http://www.ornl.gov/hgmis
• High throughput DNA digital data changed how
we think about biomedicine
• Spawned a new field – bioinformatics /
computational biology/ systems biology /
biomedical data science
• Spawned a multi billion-dollar industry

7. Basic Premise …..
We are at a new tipping point

8. Basic Premise …
“We need to be more aware than
ever of developments that may be
far outside our discipline that fall
under the broad topic of data
science. In short, we need to
become biomedical data
scientists.”
Stated another way, the
leadership role in data/informatics
afforded by the human genome
project no longer applies.

9. Data Science –
In 45+ Years in Academia I Have Never Seen Anything Like It
• It is a response to the digital transformation of
society
• It is touching every discipline (aka vertical)
• We can’t keep the students out of our classes
• Cause – large amounts of digital data
• Effect – interdisciplinarity, openness, translation,
search for responsibility and more
In summary, it is disruptive to current modes of biomedical research

10. A Data Integration Poster Child
Researcher and Assistant Professor of
Medicine Dr. Thomas Hartka, also a
current online Masters in Data Science
student, is combining two disparate
data sets—electronic health records
and DMV crash data—to save lives
after motor vehicle crashes.
“I enrolled in the MSDS program to
expand my research on automotive
safety. I have already used
techniques from classes in my work.
I hope to expand my research to
real-time analytics to improve
emergency room care.”
— Dr. Thomas Hartka, UVA School
of Medicine

11. Data Science
As a Driver Its Just the Beginning….
https://zenodo.org/records/7768414
Data scientist jobs are predicted to experience 36
percent growth between 2021 and 2031, according
to the US Bureau of Labor Statistics.
The global data science platform market size was
valued at USD 64.14 billion in 2021 and is projected
to grow from USD 81.47 billion in 2022 to USD
484.17 billion by 2029, exhibiting a CAGR of 29.0%
during the forecast period.
Data science is the fastest emerging field around the
globe.

12. Given these precedents about data and data
science we should start with a definition/framework

13. Big data and data science are like the Internet…
If I asked you to define them you would all say
something different, yet you use them every day…
http://vadlo.com/cartoons.php?id=357

14. One Definition of Data Science –
The 4+1 Model (aka domains)
• Value – assuring societal
benefit
• Design - Communication
of the value of data
• Systems – the means to
communicate and
convey benefit
• Analytics – models and
methods
• Practice – where
everything happens
[Raf Alvarado & Phil Bourne https://doi.org/10.1142/9789811265679_0004]

15. The Data Science Interplay
• Value + Design = Openness,
responsibility
• Value + Analytics = Human
centered AI, algorithmic bias
• Value + Systems =
sustainability, access,
environmental impact
• Design + Analytics = literate
programming, visualization
• Design + Systems =
dashboards, engineering
design
• Analytics + Systems = ML
engineering
Thinking of data as a science unto itself is novel and controversial
[Raf Alvarado & Phil Bourne https://doi.org/10.1142/9789811265679_0004]

16. With this definition let’s explore the
implications for biomedical research …

17. The 4+1 Model - Systems
• Value – assuring societal
benefit
• Design - Communication
of the value of data
• Systems – the means to
communicate and
convey benefit
• Analytics – models and
methods
• Practice – where
everything happens
[Raf Alvarado & Phil Bourne https://doi.org/10.1142/9789811265679_0004]

18. Systems….
Science, 377 (6603), .
DOI: 10.1126/science.abo5947

19. Systems….
• Need something akin to the electricity grid or banking system
• Need to consider data and methods as first-class data objects
• Examples: European Open Science Cloud (EOSC), the CS3MESH4EOSC Science
Mesh, the China Science and Technology (CST) Cloud, the African Open Science
Platform, the South African National Integrated Cyber Infrastructure System, the
Malaysia Open Science Platform, the Global Open Science Cloud (GOSC) the
Australian Research Data Commons (ARDC) Nectar Research Cloud, the Digital
Research Alliance of Canada (formerly known as the New Digital Research
Infrastructure Organization), and the Arab States Research and Education
Network.
• Problems span funding agencies; solutions do not
• There is a lack of public-private partnership

20. Analytics ….

21. AlphaGo – Take Home Messages
https://www.alphagomovie.com/
1. Even the programmers were
disquieted by creating
something better than any
human
2. AlphaGo made a move that no
human Go expert nor
programmer anticipated
3. It takes a lot of resources to
defeat the world champion
Go has more moves than there are atoms in the universe

22. Proteins have ~20**300 combinations also more than the
number of atoms in the universe

23. Science Games….

25. AlphaFold2 Makes Significant Leap

26. AlphaFold2
Numerical optimization – differential programming
Overall gradient descent trained to win CASP
Jumper et al.., 2021. Nature, 596 (7873),
pp.583-589
Transformer models using attention
Geometry invariant to
translation/rotation

27. Logistics Behind the Win
● Nothing fundamentally new from an AI perspective
● Data Integration
● Collaboration not competition
● Engineering challenge beyond most labs
● Compute power beyond most labs
● Team size beyond most labs
● Worked with protein structure specialists

28. Downstream Implications
• Cooperation rather than competition
• Public-private partnership
• Translational possibilities are endless
• Made possible by curated open data
• Appreciate engineering

29. Scientific Implications

30. Exploration of Latent Space
Rethink fold space? Rethink classification schemes?

32. The 4+1 Model - Design
• Value – assuring societal
benefit
• Design - Communication
of the value of data
• Systems – the means to
communicate and
convey benefit
• Analytics – models and
methods
• Practice – where
everything happens
[Raf Alvarado & Phil Bourne https://doi.org/10.1142/9789811265679_0004]

34. Beyond data science the academic landscape
is changing….

35. https://doi.org/10.1038/sdata.2016.18
https://www.heliosopen.org/
The One Lever Left in Open
Scholarship is Academia Itself

36. Openness/FAIR
Data Science would not exist if it were not for open
data and methods. It would be wrong for us to take
and not give back

https://datascience.virginia.edu/policies

37. Questions I Leave You With ….
• Are we indeed at a change point?
• Will biomedicine continue to lead data science?
• Do we need new models for doing science?
• Are we placing the right emphasis on our research
products, notably data and methods vs papers

38. Questions?

39. Databases
organize data
around a project.
Data warehouses
organize the data
for an organization
Data commons
organize the data
for a scientific
discipline or field
Data
Warehouse
Data Ecosystems
How we think about our
infrastructure is important

40. Challenges
Fixed level of funding
Opportunities
data commons
Data commons co-locate data
with cloud computing
infrastructure and commonly
used software services, tools &
apps for managing, analyzing and
sharing data to create an
interoperable resource for the
research community.*

41. But wait the picture is more complicated….

42. Data Science versus Data Engineering – How
Much Emphasis Where?

43. Coming back to the question…
So we have a definition of data science and we
have a set of guiding principles, where does this
take us?
Stated another way, what do we want to be
recognized for in 10 years?
https://pebourne.wordpress.com/

44. Research ethics
committees (RECs) review
the ethical acceptability
of research involving
human participants.
Historically, the principal
emphases of RECs have
been to protect
participants from physical
harms and to provide
assurance as to
participants’ interests and
welfare.*
[The Framework] is
guided by, Article 27
of the 1948 Universal
Declaration of Human
Rights. Article 27
guarantees the rights
of every individual in
the world "to share in
scientific
advancement and its
benefits" (including to
freely engage in
responsible scientific
inquiry)…*
Protect human
subject data
The right of human
subjects to benefit
from research.
*GA4GH Framework for Responsible Sharing of Genomic and Health-Related Data, see goo.gl/CTavQR
Data sharing with protections provides the evidence
so patients can benefit from advances in research.
Balance protecting human subject data
with open research that benefits
patients
[Adapted from Bob Grossman]

45. Why Responsible Data Science?
• A defining feature
• A partnership between STEM, social
sciences and the humanities
• Where UVA has strength

48. Daily Challenges
• Deciding what not to do
• Competition for the best team members (faculty and staff)
• Establishing a diverse team
• Lack of a comprehensive enterprise-wide data infrastructure
• Its easier to conform
