Helani Perera

About

I am a dedicated Environmental Engineer with an MSc in Environmental Engineering from New Mexico State University and a First-Class BSc (Hons) in Civil Engineering from the Sri Lanka Institute of Information Technology. My research has focused on sustainable water treatment technologies, particularly the mitigation of membrane scaling in reverse osmosis systems through electromagnetic field (EMF) pretreatment.

With experience as a Graduate Research Assistant and contributions to peer-reviewed journals and international conferences, I bring deep expertise in water resources, membrane science, and environmental systems analysis. I also have hands-on experience with tools like ArcGIS, QGIS, HEC-HMS, and AutoCAD.

I am passionate about applying scientific principles to address real-world environmental challenges. Whether in academia, consulting, or the water industry, I aim to contribute to innovative, sustainable, and data-driven solutions that will shape the future.
