In October 2019 the university opened a new Data Science Research Center, which has been very active in promoting data science (DS) at the university of Haifa (see https://dsrc.haifa.ac.il/).

The center is promoting two main goals, capitalizing on the unique advantages of the University of Haifa for DS research.

Goal 1: Promoting multidisciplinary research in DS

Researchers from the University of Haifa who are working in the DS area come from 14 different departments, emphasizing either core DS disciplines or application areas. The application areas present real-life challenges not yet addressed by DS that could also be the starting point for development of novel DS methods.

Goal 2: Promoting collaboration of academic researchers with industry and the public sector

The university of Haifa is going through major transformation with the planned opening of the new Namal campus in Haifa (the first campus in Israel to be in the center of a business, entrepreneurship, and entertainment district, and walking distance from a train station), and the opening of the Rakevel from the Lev Hamifratz train station to the Mountain Campus. The DS Center is planned to be part of a new School of Data Science located at the Namal campus.

The center is establishing a new DS Service Unit to broaden the support for researchers and strengthen connections with industry, and is looking to recruit people for the following positions:

2) Chief Data Scientist – long-term (>= 5 years) position

Role:
– Support and advance data science research at the university of Haifa
– Promote activities to engage researchers in collaborative research in data science
– Advise researchers on their data science projects
– Supervise the data science service unit
– Help with planning and overseeing the education plans of the center
– Advise on data science grant programs
