He cofounded the USF spinoff company Modelithics, whose customers include major U.S. defense contractors Harris Corp., Northrop Grumman and Raytheon.Sarkar, chair of the department of computer science & engineering in the USF College of Engineering, developed a new imaging device that can be used to collect data about the physical characteristics of human skin critical in diagnosing diseases such as melanoma. He also pioneered the area of gait biometrics, which analyzes the unique characteristics of the ways in which individuals walk.Lawrence is a professor in the department of oncologic sciences at USF and a senior member of Moffitt Cancer Center's drug discovery department, where he has made important contributions in designing and synthesizing organic molecules to act as anticancer agents.And Morejon, chief technology officer at enVerid Systems, is an inventor and manufacturer of LED lighting and guided missile technologies. He is a USF alumnus with a degree in engineering and member of the board of directors for the USF Research Foundation.The NAI was founded at USF in 2010 to recognize and encourage inventors with patents issued from the U.S. Patent and Trademark Office, enhance the visibility of academic technology and innovation, encourage the disclosure of intellectual property, educate and mentor innovative students, and translate the inventions of its members to benefit society.USF now has 18 faculty members who are NAI fellows.
