Serbian-American physician Dr. Nebojša Nick Knežević, who works in Chicago, has earned international recognition after ranking among the top 0.25% of researchers in anesthesiology worldwide. His achievement highlights the growing contribution of Serbian-born medical professionals to American healthcare and scientific research.
Knežević ranked 147th among 59,383 researchers in anesthesiology in the 2026 Stanford–Elsevier citation database, according to published bibliometric data.
The Serbian-American doctor also appears among the world’s top 2% of scientists in the database, which evaluates research influence using standardized citation indicators.
From Serbia to Chicago’s Medical Community
Knežević studied medicine at the University of Belgrade before continuing his professional development in the United States.
Today, he is affiliated with the University of Illinois College of Medicine in Chicago, where his work focuses on anesthesiology, surgery and pain medicine.
He also serves in a research and education leadership role at Advocate Illinois Masonic Medical Center.
His scientific interests include chronic pain, pain management techniques and improving treatment outcomes for patients with long-term medical conditions.
Over more than two decades, Knežević has contributed to numerous scientific publications and collaborated with researchers in several medical disciplines.
His Scopus-linked ScienceDirect profile lists more than 230 publications and thousands of citations.
These figures reflect the extent to which other researchers have referenced his published work.
For Knežević, however, the purpose of medical research extends beyond academic recognition.
In public comments following the latest ranking, he emphasized the importance of turning scientific discoveries into practical improvements in patient care.
He also acknowledged the contributions of colleagues, mentors and students throughout his career.
What the Stanford–Elsevier Ranking Means
The Stanford–Elsevier database evaluates scientists using information from Scopus, one of the world’s major research citation databases.
Researchers are assessed using several indicators, including citations, the h-index and measures that account for co-authorship.
The database includes both career-long research impact and performance during an individual year.
In the 2026 single-year ranking, Knežević placed 147th in anesthesiology, putting him among approximately the top quarter of one percent of researchers in that field.
His recognition is particularly significant for the Serbian-American community, which has a long history of contributions to medicine, science and higher education in the United States.
Chicago remains one of the most important centers of Serbian-American community life.
Knežević’s professional achievements offer another example of how physicians and researchers with roots in the Balkans contribute to American institutions.
His continued presence in international research rankings also reflects the importance of scientific collaboration and medical education across national borders.
While citation rankings measure research influence rather than clinical performance, they provide an indication of how widely a scientist’s work contributes to further studies.
For Knežević, the latest recognition marks another milestone in a career dedicated to advancing pain medicine and improving patient care.
