About me

I am a PhD researcher belonging to the Icing Research Group at Tampere University under the supervision of Dr.Tech. Heli Koivuluoto. I am working on flame and cold spray coatings to produce durable slippery liquid infused porous surfaces (SLIPS) for anti-icing applications. The work involves optimizing coating parameters, characterizing the coating structure using different methods, icing/ de-icing tests, besides ice adhesion strength tests.
