A few words about me

I'm a physicist/quantum computing scientist. My professional path started about a decade ago when I joined Vahid Karimipour's research group and took me all around the world. I also love to travel and ocasionally like to do something crazy/dangerous (in my own scale). Currently, I hold an assistant professor position and wait to see what my path would bring me next.


I did my BSc at Sharif University of Technology. I had the privilage to work closely with Vahid Karimipour, Reza Rahimitabar and Abdollah Langari.


I did my masters degree in Calgary, in Canada. It was my first time traveling to a foreign country on my own and so many adventures. I worked with Christoph Simon on macroscopic quantum effects. I also did a project with Barry Sanders on Quantum Simulations.


I did my PhD under Michele Mosca at the Institute for Quantum Computing at the University of Waterloo. It was one of the most educating periods of my life, scientifically and otherwise. I also got to work closely with experimentalists and even spent sometime doing experiments myself.


After my PhD, I moved across the atlantic ocean to Germany and started my first (sort of) real job as a postdoctoral fellow at the University of Erlangen and Max Planck Institute for the science of light in Erlangen. I worked with Florian Marquardth and started doing research in the field of Optomechanics.


My research is mostly focused on foundations and practical aspects of theory of Quantum Mechanics. Here's a list of things that keep me up at night.

Macroscopic Quantumness

Why can't we see quantum effects in our macrscopic everyday-life? What happens to the quantum phenomena when it gets to large scale systems? We have studied some aspects of this problem and we digging even further. For instance, we conjectured that lack of measurement precision could be one reason for explaining the macroscpic world as we see it. To find out more, click here!

Algorithmic Cooling

This is a technique for cooling a subset of an ensemble by driving it out of equilibrium. We established the cooling limit of all algoritmic cooling techniques and invented a new method that achieves the limit asymptotically and is practically feasible to implement. To find out more, click here!


Optomechanical systems provide a strong tool for testing different aspects of quantum mechanics that used to be challenging to reach. The also offer great practical promisses, from high-precision sensing to frequency transducers and quantum memories. We are working on a proposal for a cool quantum simulator based on Optomechanical arrays. To find out more, click here!
