BIO: I am Assistant Professor at Bahcesehir University department of Civil, Mechanical and Energy engineering. Prior to joining BAU, I was a postdoctoral scholar for a year at University of California Los Angeles (UCLA) with visitor position at Caltech. I received my PhD and MSc in mechanical engineering from California Institute of Technology (Caltech) in 2015 and 2010 co-advised by Michael Hoffmann (NAE) and William Goddard. (NAS) Before that, I received BSc degrees in Civil and Mechanical engineering (double major with honors) at Sharif University of Technology in 2009. I work on various projects related to physics and chemistry of electrochemical energy storage, conversation and sustainability. I use experimental tools and computational modeling to enhance the performance of energy devices and in particular the rechargeable batteries. My resume is here.

RESEARCH: 

My research interest lies on the variety of subjects related to experimenting and simulation of energy materials. In particular, I engineer electrochemical energy storage devices, with applications in rechargeable batteries, fuel cells and (super) capacitors. Future directions include enhancing the performance of energy storage devices and in particular in by investigating the physics and chemistry of electrochemical energy storage, conversion and sustainability. In particular designing the electrode/ electrolytes to investigate/suppress dendritic 

instigation/growth in rechargeable batteries.
CURRENT PROJECTS:
I. MODELING HIGH TEMPERATURE CORROSION/CRACKING OF ZIRCONIUM: Multi-physics modeling of electro-chemi-mechanical corrosion/cracking in extreme 
environments. (with Prof. Jaime Marian)
II. EXPERIMENTING/MODELING RECHARGEABLE LITHIUM METAL BATTERIES: (with Prof. Michael Hoffmann and Prof. William Goddard)  
Electrodeposition/dissolution is observed in many physical phenomena in various scales. 
The formation of dendritic aggregates occurs in the electrode surface and in particular, for lithium, which is the lightest and the most electropositive metal, and hampers it’s utilization in high energy applications. We engineer the physical and chemical methods to inhibit the instigation and growth of the amorphous aggregates. Furthermre we systematically stabilize the electrode surface passivation by electrolytic investigation.
