Ziv Bar-Joseph (Hebrew: זיו בר-יוסף) is an Israeli computational biologist. He is a professor in the Computational Biology Department and the Machine Learning Department at the Carnegie Mellon School of Computer Science. He is also a co-founder and Chief Scientific Officer at GenBio AI.
Education
Bar-Joseph earned a Bachelor of Science degree in computer science in 1997 and a Master of Science degree in computer science in 1999, both from the Hebrew University of Jerusalem. He completed his PhD in computer science at the Massachusetts Institute of Technology in 2003, with the guidance of David K. Gifford and Tommi S. Jaakkola. After earning his PhD, he worked as a postdoctoral researcher at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) and the Whitehead Institute.
Research
Bar-Joseph's research at Carnegie Mellon mainly works on creating computer-based techniques to better understand how complicated biological systems interact and change over time, such as the cell cycle.
At MIT, Bar-Joseph's team created a new method to identify groups of genes in yeast that work together to perform tasks like making energy, building proteins, and responding to stress.
He is also interested in how ideas from computer science and biology can help each other, especially how natural processes can inspire improvements in computer algorithms used for tasks like distributing work across multiple systems.
In 2022, Bar-Joseph served as Vice President and Head of R&D Data and Computational Sciences at Sanofi. In 2025, he joined GenBio AI as a co-founder and Chief Scientific Officer.
Awards and honours
Bar-Joseph received the DIMACS-Celera Genomics Graduate Student Award in Computational Molecular Biology and the NSF CAREER award. In 2012, he was honored with the ISCB Overton Prize for his important and long-lasting contributions to computational biology.
He helped lead the Research in Computational Molecular Biology (RECOMB) conference in 2009 and 2010. In 2013, he became part of the board of the journal Bioinformatics as an Associate Editor.
Personal life
Bar-Joseph is an enthusiastic runner who has completed several marathons in under three hours. He resides in Pittsburgh and Shoham with his wife and three children.
