## Contributions
Daniel Cohen-Or completed his Ph.D. at the State University of New York at Stony Brook in 1991 under the supervision of Arie E. Kaufman. He has supervised doctoral students who became prominent researchers, notably Olga Sorkine-Hornung and Yaron Lipman. Cohen-Or's work in computer graphics, geometry processing, and visual computing was formally recognized by the Association for Computing Machinery when he was named an ACM Fellow in the 2021 cohort (announcement dated 2022-01-19) "for contributions to computer graphics, geometry processing, and visual computing." His professional and bibliographic presence is documented across multiple scholarly systems: DBLP (dblp_author_id: c/DCohenOr), MathSciNet/MR (mr_author_id: 641523), IEEE Xplore (ieee_xplore_author_id: 38273141800), Google Scholar (google_scholar_author_id: fAxws1sAAAAJ), and library identifiers including ISNI (0000000051448463) and VIAF (41655826). These records indicate an extensive publication and research profile in the domains cited by the ACM fellowship, and they provide access points for his papers and citations.

## FAQs

## Why They Matter
Daniel Cohen-Or's significance is documented through formal recognition and academic lineage. The Association for Computing Machinery named him an ACM Fellow (2021 cohort, announced 2022) specifically "for contributions to computer graphics, geometry processing, and visual computing," which is a selective honor that highlights sustained and influential research in those areas. His role as a doctoral advisor to researchers such as Olga Sorkine-Hornung and Yaron Lipman ties him to subsequent advances in geometry processing and graphics; those students have themselves become recognized contributors, indicating Cohen-Or's influence through mentorship. His presence across major bibliographic and scholarly databases (DBLP, MathSciNet, IEEE Xplore, Google Scholar, ISNI, VIAF) demonstrates a documented body of work that other researchers can trace and build upon. Without his contributions and mentorship—as represented in the ACM citation and supervisory record—some lines of research in geometry processing and visual computing would have a different lineage and potentially less continuity.
