Humberto Jaramillo is a fifth-year Ph.D. Candidate and a National Science Foundation Graduate Research Fellow in the Elimelech Research Group in the Chemical and Environmental Engineering Department at Yale.  His research focuses on the prevention of scaling of calcium sulfate dihydrate during the treatment of brackish water in reverse osmosis (RO) systems.  

Controlling the precipitation of sparingly soluble salts during brine treatment continues to be a challenge, hence forestalling the utilization of membrane processes for the treatment of high salinity feedwaters. Currently, Humberto is part of the Nanosystems Engineering Research Center for Nanotechnology Enabled Water Treatment (NEWT) where he is pursuing to advance our understanding of gypsum scale formation in RO, and develop membranes with anti-scaling properties.

During his time at Yale, Humberto has also been involved in the development of anti-fouling thin-film composite forward osmosis membranes for treating wastewaters heavily laden with organic matter. Membrane surface modifications included the grafting of a hydrophilic block copolymer and graphene nanosheets to the active layer.  

Humberto’s academic career began in Bergen Community College by earning an Associate in Arts in 2007.  Humberto shifted to the natural sciences, and studied Natural Resources Conservation for one year at the University of Montana.  At that point in time, Humberto decided to major in Civil and Environmental Engineering, and attended Rutgers The State University of New Jersey, where he graduated with honors in May 2013.  During his leisure time, Humberto enjoys music, exercising, and experimenting in the kitchen.
