From Humble Beginnings to Personalized Digital Avatars
Exploring the evolution of a field that has revolutionized modern medicine through five decades of scientific publishing
What can the evolution of a scientific journal tell us about the dramatic transformations in a field that has revolutionized modern medicine? When Medical and Biological Engineering and Computing (MBEC) published its first issue in 1963, biomedical engineering was a niche interdisciplinary field. Researchers were pioneering early medical devices and struggling to establish their place between traditional engineering and medicine.
Today, as we reflect on fifty years of publishing in this field, we find a discipline that has not only matured but has fundamentally transformed how we approach healthcare, from personalized digital avatars of human physiology to 3D-printed tissues and AI-powered brain interfaces.
This journey through five decades of scientific publishing reveals more than just changing research trends—it uncovers a compelling story of how a scientific community evolved, raised its standards, and positioned itself to tackle some of medicine's most persistent challenges.
The pages of MBEC, one of the oldest journals in the field, serve as a time capsule documenting this remarkable transformation 1 . As we examine key publications, pivotal experiments, and emerging tools that define modern biomedical engineering, we discover a field that continues to push the boundaries of what's possible in medicine.
Biomedical engineering needed a dedicated voice in the scientific community, and in 1963, that voice emerged as Medical, Electronic and Biological Engineering—the publication that would later become MBEC. The journal began as a quarterly publication with modest ambitions, providing a platform for researchers working at the intersection of engineering and medicine 1 .

The transformation of biomedical engineering publishing over fifty years reflects a field coming of age. This maturation becomes evident when examining several key metrics: the rising standards for acceptance, the increasing specialization of research, and the growing collaboration across disciplines and geographies.
As MBEC's rejection rate doubled over a six-year period, the journal maintained consistent quality assessment criteria. Reviewers scored manuscripts numerically between 1 and 100, with papers scoring over 75 usually achieving acceptance, while those between 65 and 75 depended heavily on the quality of revision 1 .
Analysis of highly-cited papers from 1975 onward shows that in the early decades, 30-50% of top papers focused on the heart and circulation. Over time, studies evolved to include emerging fields like image processing, tissue engineering, and patient-specific modeling 1 .
| Metric | 1986 | 2016 | Change | Significance |
|---|---|---|---|---|
| Authors per paper | 3.1 | 5.8 | +87% | Increased specialization and collaboration |
| Institutions per paper | 1.4 | 2.5 | +79% | Growing interdisciplinary approach |
| Countries per paper | 1.1 | 1.5 | +36% | Internationalization of research |
| Reference list | 21.7 | 42.2 | +94% | Deeper integration of existing knowledge |
| Printed pages | 15.5 | 12.3 | -21% | More concise reporting despite complexity |
In 1986, female first authors were virtually absent from publications in prominent biomedical engineering journals, but by 2016, women accounted for 28.6% of first authors and 20.4% of corresponding authors . This progress, while incomplete, reflects broader changes in the composition of the biomedical engineering community and its leadership.
As biomedical engineering matured, its ambitions grew accordingly. Recently, a consortium of 50 experts from 34 elite institutions worldwide identified five grand challenges that represent the frontier of the field 2 5 . These collaborative priorities highlight how biomedical engineering has evolved from creating basic medical devices to tackling some of medicine's most complex problems.
Developing accurate digital models of individual patients' physiology that incorporate multimodal measurements, comorbidities, medications, and potential risks to enable hyper-personalized care 2 .
Advancing stem cell engineering, manufacturing, and gene editing to create tissues and organs on demand for permanent or temporary implants 5 .
Leveraging artificial intelligence to analyze brain states through everyday situations, develop brain prosthetics, and create AI models of brain anatomy and physiology 2 .
Strategically harnessing the immune system to redesign human cells as therapeutic technologies, building on successes in cancer immunotherapy 5 .
"What we've accomplished here will serve as a roadmap for groundbreaking research to transform the landscape of medicine in the coming decade" — Dr. Michael Miller, professor and director of the Department of Biomedical Engineering at Johns Hopkins University 2 .
To understand how biomedical engineering is rising to these grand challenges, we can examine a specific research approach that embodies the field's current direction: the development of personalized physiology avatars. This methodology represents the cutting edge of biomedical engineering, combining computational modeling, patient-specific data, and clinical application.
Researchers first gather comprehensive data from individual patients using wearable sensors, medical imaging, genomic sequencing, and clinical assessments 2 .
Using this data, researchers create a computational framework—a "digital twin"—that can simulate physiological processes 1 .
The validated avatar is used to simulate different treatment approaches, predict disease risk, and optimize therapeutic strategies 5 .
| Application | Current Approach | Digital Avatar Approach | Potential Improvement |
|---|---|---|---|
| Treatment planning | Population-based guidelines | Patient-specific simulation | Reduced adverse effects, improved outcomes |
| Drug development | Extensive clinical trials | Preliminary in silico testing | Faster development, reduced costs |
| Risk prediction | Statistical models based on limited factors | Comprehensive modeling incorporating multiple data streams | Earlier intervention, improved prevention |
| Surgical planning | Standardized approaches based on anatomy | Procedure rehearsal on patient-specific model | Reduced complications, shorter operations |
| Chronic disease management | Reactive adjustments based on periodic assessments | Continuous monitoring and predictive modeling | Fewer hospitalizations, better quality of life |
"Innovations in the form of multi-scale sensors and devices, creation of humanoid avatars and the development of exceptionally realistic predictive models driven by AI can radically change our lifestyles and response to pathologies" — Dr. Shankar Subramaniam, lead author of the grand challenges task force 5 .
The experiments driving biomedical engineering forward rely on an increasingly sophisticated toolkit. Here are some of the essential materials and technologies that enable cutting-edge research in the field:
Microengineered systems that replicate human organ-level physiology outside the body, allowing researchers to study tissue behavior and disease progression 9 .
Genome-editing tools that allow researchers to rewrite DNA by cutting only a single strand to add, remove, or replace base pairs 9 .
Devices that gather continuous, real-time physiological data from patients, providing the massive datasets needed to develop digital avatars 2 .
Micron-sized particles filled with gas that can be loaded with drugs and release their payload when disrupted by targeted ultrasound 9 .
Systems that use robotic exoskeletons and treadmills to help patients recover basic motor functions after strokes or brain injuries 9 .
Advanced manufacturing systems that create living tissues by depositing cells in precise patterns layer by layer 9 .
The fifty-year journey of biomedical engineering publishing reveals a field that has dramatically transformed itself—from its early focus on basic instrumentation to its current ambition to solve medicine's most persistent challenges. This evolution is reflected not only in the pages of journals like MBEC but in the very way biomedical engineers approach problems, collaborate across disciplines, and define success.
What began as a niche interdisciplinary effort has grown into a field capable of engineering tissues, reprogramming immune systems, and creating digital twins of human physiology.
The increasing rigor evident in publishing metrics—the higher rejection rates, the growing collaboration, the more sophisticated research questions—tells a story of a discipline maturing into its potential.
As we look to the future, the grand challenges facing biomedical engineering are significant, but the field is better positioned than ever to address them. The development of personalized digital avatars represents just one example of how biomedical engineering continues to push boundaries. These advances promise not just incremental improvements but fundamental transformations in how we understand, maintain, and restore human health.
The reflection on fifty years of publishing ultimately reveals a simple truth: biomedical engineering has moved from the periphery to the center of modern medicine, and its journey is far from over. With an evolving toolkit and expanding ambitions, the field continues to redefine what's possible at the intersection of engineering and life sciences.
