Brief Bio:

I am Assistant Professor of Mechanical Engineering at Bogazici University as well as Visiting Researcher at Caltech . I received the BSc in Civil and Mechanical Engineering (double major, top 2%) from Sharif University of Technology in 2009 and the MSc and PhD in Mechanical Engineering from California Institute of Technology , in 2010 and 2015, respectively. Previously I was Assistant Professor at American University of Beirut (’19-’22) and Lecturer at Bahçeşehir University (’16-’19) and prior to that I was Postdoctoral Associate at UCLA Materials Science department (’15-’16). My research has been in developing multi-physics/chemistry methods and materials for energy storage, conversion, transport and sustainability. Current projects include analysis and design of state-of-the-art sustainable rechargeable batteries and prediction of heterogeneous cracking behavior for membranes/clads exposed to extreme states. Here is my Google Scholar page.
