Research Focus

Four threads that keep pulling on each other — hardware that measures the environment, models that explain it, and buildings that have to survive it.

Sensing / IoT

About

I'm a graduate Research Assistant at SUNY ESF's Baker Lab in Syracuse, NY, working under Prof. Shayan Mirzabeigi, and beginning a Master's program at SUNY ESF in August 2026.

Before moving into environmental research, I spent over a decade in mechanical design, CFD, and project management — designing HVAC systems, running Ansys Fluent simulations, and managing engineering teams in Tehran. That background now shapes how I approach environmental sensing and building science: as systems to be measured, modelled, and improved.

Art & Life

Sacred Geometry, in Marker

Outside of research, I draw detailed geometric compositions in marker on black canvas — including a full reproduction of the Notre-Dame rose window. The same precision that goes into a state-machine algorithm or a CFD mesh shows up here as radial symmetry and pattern. I'm currently developing a Sacred Geometry series exploring Gothic rose windows and Islamic geometric tilework.

On Two Wheels, and on the Pitch

I ride regularly and follow soccer closely — both a counterbalance to long stretches at a workstation and, if I'm honest, another kind of systems thinking: pacing, positioning, reading a changing field in real time.
