She is currently a Visiting Scholar at NYU and an adjunct professor at Columbia University where she teaches environmental politics in Israel. Shahar is the Director of the Faculty Engagement Program at the JCRC of NY and is working with faculty members all across NYC.

Shahar research work is focused on environmental peacemaking in the Middle East. She has investigated past and present efforts to develop and implement environmental enterprises along Israeli-Arab borders.  Shahar received her degrees from Tel Aviv University.

Shahar's interest in the Environmental Peacemaking field is not mere academic and she has been part of the environmental movement and the peace camp in Israel for many years. In 2007 she had co-founded and coordinated the “Van Leer Jerusalem Forum on Environment and Regional Sustainability", which focused on creating and enhancing cooperation between Israeli, Jordanian and Palestinian environmental experts (scientists, non-governmental and governmental actors), building capacity and deepening the knowledge on shared environmental problems and opportunities.

Shahar worked with many NGOs in Israel and played a part in various environmental initiatives both in local and in regional scale.
