Ramanathan Sugumaran, Founder of GeoTREE

Dr. Ramanathan Sugumaran (Sugu) was the founder and Director of GeoTREE from 2006-2012. Dr. Sugumaran passed away suddenly on January 25, 2017. Sugu leaves a tremendous legacy at UNI. He was a tirelessly positive influence on the students he advised, his employees in the GeoTREE Center, and his peers and colleagues. Sugu's tremendous curiosity and enthusiasm for addressing real world issues using geospatial technologies was an inspiration to many at UNI and throughout the state of Iowa. The invaluable mentor-ship that Sugu provided has been credited by many of his former students and GeoTREE employees as contributing tremendously to their success as they have moved on to careers in academics, private industry, and government service. Sugu was truly a one of a kind person whose sense of humor and infectiously positive attitude will be missed.
