Hello! I am an enthusiastic researcher at an intersection between computer science, and electrical engineering, applied mathematics, theoretical physics and neurophysiology. Beyond my scientific career, I enjoy running, climbing, music, photography, studying linguistics and new languages, English literature, history and archaeology. Learn More

Research Interests

Through my passion, teaching, and working as a researcher at different universities internationally, my experience has covered a wide range of topics in computer science, electrical engineering and applied mathematics. My main research interests span a wide range of topics in high-performancve computing (HPC), programming languages and compilers, distributed systems, computer networks, embedded systems, applied mathematics, machine learning and neuroscience.
Recently, I am developing new mathematical models, computational tools and simulation environments for analysing the human nervous system (neurons, and glial cells such as astrocytes and microglia). Our final goal aims at providing a unified computational framework for studying neurodegenerative diseases like dementia, particularly Alzheimer, within this ecosystem for neuroscience and biological communities by exploiting the power of cutting-edge supercomputers. We are also colloborating with experimental biologist in order to get deeper, more than realistic insight into human brain in our models.
In the field of computer science, I have always wanted to (a) create innovative tools to help people become more productive when doing computer programming, and (b) optimise performance of computer systems and computer programs through novel parallelisation techniques and implementing unified software infrastructures.

I have been providing numerous services to the academic communities as follows:

●  Research Assiatant, Department of Electrical Engineering, Shahed University, Tehran, Iran. I have worked in Integrated Circuits and Systems Lab (ICSL) of Dr. M. B. Ghaznavi-Ghoushchi.

●  Research Assiatant, Department of Computer Engineering, Sharif University of Technology, Tehran, Iran. I have worked in VLSI Lab of Dr. Shaahin Hessabi. I founded Parallel & Distributed Systems Lab (PDSL) in 2014 in collaboration with Dr. Shaahin Hessabi.

2001 - 2010

Social Networks
Administrator and Web Developer

For virtually 10 years, I was developing national online social network services which hosted millions of users. In 2001, I started to develop one of the first blogging services in my home country called IranBlog.com. In 2006, I developed the first Twitter-like service in my country that had Facebook-style social network capabilities named Peyghamak.com. These projects were developed based on distributed computing concepts where the service could scale up on demand. For this reason, I developed a course to teach students with web design and development in university. I was with World Wide Web (W3) since its beginning days.

2002 - Current

Commercial Software Projects
Software Architect and Web Developer

I have implemented a large number of software projects.


I have written a textbook in distributed systems, which is currently under final publication with Taylor & Francis, Florida, USA. This book spans over my obtained experience to build different distributed middleware components particularly in Grid and Cloud Computing. It teaches the reader how to construct a complex distributed software infrastructure from the ground-up.
Furthermore, I have a new plan to write two different book titles in Modeling & Simulation. More information will be posted here in the future as soon as they are available in this regard. The list of my books comes as follows:
