I am a Geohydrologist Associate Professor with experience in a wider range of groundwater research and consulting projects. I have consistently published in theoretical and field practical work on a variety of hydrogeology/geohydrology fields with main purpose of improving groundwater site characterization techniques in aquifer pumping tests, assessment of hydrogeochemical processes and their influence on groundwater quality. Professor Modreck Gomo is serving as an Editorial Boarder Member for Sustainable Water Resources Management (SWAM) and Discover Water journals.
