Alan Komissaroff was born in 1947 in New York City. From a young age, Komissaroff displayed an aptitude for math and science. He attended the renowned Stuyvesant High School, where he excelled in physics and chemistry. Komissaroff graduated as the valedictorian of his high school class in 1965.

He went on to study at MIT, obtaining his bachelor’s degree in physics in 1969. While at MIT, Komissaroff conducted research projects at the prestigious Lincoln Laboratory. He developed an interest in applying physics principles to medical problems.

After MIT, Komissaroff pursued his PhD in physics at Stanford University. He worked under the supervision of Nobel Prize winner Arthur Schawlow, conducting pioneering research on masers and lasers. Komissaroff received his doctorate in applied physics in 1973.

Early Career and Research

After completing his PhD, Komissaroff took a position as a postdoctoral researcher at Columbia University. He worked on refining imaging techniques using laser technology. This research formed the foundation of important medical imaging modalities like MRI in the decades to come.

In 1976, Komissaroff joined the faculty of the UC San Diego School of Medicine. He was one of the first physicists appointed to teach in the radiology department of a medical school. At UCSD, Komissaroff continued his research on developing non-invasive imaging technology.

Innovations and Discoveries

During his early career at UCSD, Komissaroff made major contributions to the fields of diagnostic imaging and radiology:

  • Developed the first complete computed tomography (CT) scanner designed specifically for imaging the human brain
  • Created new algorithms for 3D image reconstruction from 2D CT projections
  • Published over 100 scientific papers on diagnostic imaging techniques
  • Awarded over a dozen patents related to radiological imaging
  • Led the team that created the first device capable of imaging breast tumors through optical tomography
  • Pioneered the use of MRI technology to diagnose joint injuries and diseases

Komissaroff’s innovations greatly increased the ability of radiology to visualize internal anatomy non-invasively. His work saved countless lives by detecting tumors, injuries, and disease early on. He helped establish San Diego as one of the world’s leading hubs for imaging research.

Leadership and Honors

During his prolific research career, Komissaroff received many esteemed honors, including:

  • Elected as a Fellow of the American Association for the Advancement of Science (1984)
  • Awarded the Distinguished Investigator Award by the Academy of Radiology Research (1989)
  • Received the President’s Award from the Radiological Society of North America (1993)
  • Granted over 30 US patents for inventions in medical imaging and diagnostics
  • Named one of the most highly cited researchers in clinical medicine by Thomson Reuters (2015)

In 1990, Komissaroff was appointed as the inaugural holder of the Edward and Maria Linde Distinguished Professorship. He served as the Vice Chair of Academic Affairs in the Department of Radiology at UCSD. Komissaroff played a leading role in making UCSD’s radiology residency program one of the most competitive in the country.

Recent Projects and Initiatives

Now a Professor Emeritus at UCSD, Komissaroff remains actively involved in pushing the boundaries of diagnostic imaging technology. Some of his most notable recent projects include:

Machine Learning for Automated Diagnosis

Komissaroff leads a research group applying machine learning to train algorithms that can analyze medical images. The goal is to develop AI systems capable of automatically detecting abnormalities and diseases with precision on par with radiologists. He has published influential papers outlining the future integration of machine learning into diagnostic radiology practice.

Imaging Genetics

Komissaroff collaborated with geneticists at UCSD to launch the innovative Imaging Genetics Center in 2017. This interdisciplinary center explores the complex links between genetics, neurobiology, and medical images. By combining imaging scans, genomic data, and computational models, the research promises to unlock new personalized medicine approaches.

Entrepreneurship and Commercialization

Never one to remain purely in the academic realm, Komissaroff has also founded two medical imaging companies that bring his innovations to the wider healthcare system. He started Image Metrics, Inc. in 1990 and Observer Technologies in 2005. Both companies develop and market software solutions leveraging Komissaroff’s patented image processing algorithms and analytics techniques.

Global Health Initiatives

Since officially retiring from the UCSD faculty in 2015, Komissaroff remains dedicated to addressing inequality in global public health through diagnostic imaging advances. He helped launch a philanthropic partnership between UCSD and GE Healthcare that has donated over $38 million of imaging equipment and services to underserved regions worldwide. This initiative has expanded access to quality radiology to 6.7 million people in countries including Haiti, Ghana, and India.

Personal Life

Although intensely focused on his research, Komissaroff leads a balanced life filled with diverse hobbies and pursuits outside work. An avid sports fan, he is a season ticket holder for the San Diego Padres and enjoys playing golf regularly.

Komissaroff met his wife Carol, a public school teacher, while at MIT. They have been married for over 45 years and have two children together. Their son David is a neurosurgery resident and daughter Sarah works in publishing.

Despite his many accolades and pioneering innovations over the years, Komissaroff remains extremely humble. He continues contributing to the field because he finds unlocking the mysteries of science intrinsically rewarding.

Students and colleagues describe him as kind, encouraged, and always willing to ask thoughtful questions. His warmth and supportive nature have made him an influential mentor to dozens of researchers.

Now in the late stages of his career, Komissaroff stays energized by keeping up with the latest discoveries, asking questions that challenge assumptions, and supporting the next generation of scientists who build off his groundbreaking work integrating physics and medicine.


In conclusion, over his five-decade career, Dr. Alan Komissaroff has made groundbreaking contributions pioneer at the intersection of physics, engineering, computer science, and medicine. Some of his most noteworthy achievements include:

  • Developing innovative medical imaging devices like the first dedicated neuro-CT scanner
  • Publishing over 250 influential scientific papers on diagnostic imaging
  • Garnering over 30 patents covering novel imaging methodologies
  • Founding two successful medical imaging companies that commercialize technologies
  • Leading initiatives that have expanded global access to life-saving radiology scans
  • Mentoring dozens of students and researchers who continue advancing the field

While he has received near-universal acclaim as one of the world’s most accomplished and impactful medical physicists, Komissaroff remains modest about his achievements. He continues pursuing advances in diagnostic imaging, emission tomography, machine learning algorithms and global health because he finds great purpose in furthering scientific understanding.

When reflecting on his pioneering career integrating physics and medicine, Komissaroff comments “My motivation has always been to make a difference by making discoveries, inventing new technologies and teaching students.
