I’m a steady, hands-on engineer who likes turning careful simulations into simple rules others can use. My main interest is non-Newtonian flow in small devices and in the human body. I work mainly with COMSOL and CFD, and I verify results against known solutions before moving to more complex models.

I enjoy projects that connect fundamentals to practical outcomes—microfluidic separation, hemodynamics, and flows in porous media. I value good lab culture and clear reporting as much as final results.

Interests

I stay active—volleyball and football are my main sports (I’ve played at a semi-professional level), and I enjoy swimming and cycling whenever I can. Off the court, I like chess and other board games for the focus and strategy. I also spend a good part of my free time with films and series—I love discovering strong stories and craft. I read literature, especially Dostoyevsky, and I listen to music to unwind.
