Rabbi Jason Rubenstein

Jason Rubenstein comes to Slifka Center from a background as diverse as Yale’s Jewish community: a childhood at Temple Micah in Washington DC, formative years studying at Yeshivat Ma’ale Gilboa in northern Israel, and rabbinic ordination at the Jewish Theological Seminary. For the past eight years Jason has taught on the faculty of the Hadar Institute, where he’s created classrooms, conversations, and communities that bring Torah to life by drawing on the fullness of students’ lives.

From his own formative undergraduate years at Harvard Hillel, Jason personally knows the value of Slifka Center’s work. Creating a community of meaning where students forge identities as Jewish leaders and relationships with one another that will continue to grow and deepen even after graduation not only enriches the lives of individual alumni – it has the potential to reshape and enliven the American Jewish landscape through those alumni’s talents and contributions.

In addition to rabbinic ordination, Jason holds an AB in Social Studies from Harvard College and a Masters in Talmud from JTS. He is also the recipient of numerous awards including the Wexner Graduate Fellowship and the Covenant Foundation’s 2015 Pomegranate Prize for Emerging Educators.

Jason and his wife, Arielle, are grateful to be raising their two sons in beautiful East Rock, as members of the gracious and brilliant Yale Jewish community.

Rabbi Alex Ozar

Rabbi Alex Ozar and Lauren Steinberg are thrilled to be the JLIC couple at Yale beginning in Summer 2018! Together with their son Noam, they’re excited to learn and cultivate a positive, flourishing spiritual community together with students and the broader Slifka Center family.

Rabbi Alex Ozar grew up in St. Louis, MO. A fourth generation Missourian on both sides, he left home to spend two blissful years studying in Israel at Yeshivat Kerem B’Yavneh and then returned stateside to attend Yeshiva University, where he received his BA, MA and Semikha. A proud Bulldog himself, Alex is now pursuing his PhD at Yale in Philosophy and Religion, with a focus on prophetic witness and the how-to’s of pursuing justice in an often-indifferent world. He is especially excited that I-95 will no longer feature in his daily commute. Alex has worked for First Things magazine, as a Tikvah Fellow, and as a gemara teacher at Bi-Cultural Day School in Stamford, CT. In his spare time, he enjoys rocking out with the acclaimed band Three Rabbis and a Cik, exploring the outdoors, and solving the cosmos’ problems with friends and family.

Lauren Steinberg grew up in New City, NY and received her BA and MA in political science from Columbia University. After graduation, she worked as an assistant regional director for the Anti-Defamation League’s New York Regional Office, coordinating intergroup and interfaith affairs, and then as terrorism analyst at the ADL’s national Center on Extremism. Lauren traveled around the country briefing law enforcement and government officials on domestic recruitment and radicalization and was recognized for her expertise on the subject. For the past year, Lauren has directed the Jewish Community Relations Council in Stamford, Connecticut. She is excited to dive into this next chapter of her coalition and community building work, for the opportunity to learn Torah on the job, and just to be a part of the wonderful Yale and Slifka communities! In her spare time, she reads the news and as many books as possible from the library’s non-fiction new releases section and tries to get outside as much as possible.
