Electronics Engineering, at thesis defense

I'm in the last stretch of my PhD in Electronics Engineering at Islamic Azad University, South Tehran Branch, getting ready to defend my thesis. I've been teaching since 2017, first at Imam Reza International University in Mashhad and, since 2025, at Islamic Azad University's North Tehran and Pardis branches as well. Most of my classes are microprocessors, digital systems and logic circuits, along with C/C++ programming and, for biomedical engineering students, rehabilitation principles and devices.

Outside the classroom, I build and look after network and VoIP infrastructure at Torfeh Ertebat Mordad in Tehran: MikroTik and Cisco networks, office phone systems, and the Linux and Docker servers behind them.

My way into electronics went through biomedical engineering and mechatronics, and it shows in what I like to build: things where hardware, software and people meet. The project I'm proudest of is an eye-tracking system that lets someone with a spinal cord injury turn on a light or call for help just by looking at a panel.

When I'm away from the desk, I'm usually outdoors photographing nature.
