"While Jonathan was my employee, he showed a strong work ethic, an excellent attention to detail, and outstanding research capabilities. He was one of those employees you could not only depend on to be able to do a complicated task, but also depend on to actually do it in a timely manner. In the short time I was working with Jonathan I had the pleasure of giving him multiple performance awards for taking on extra work, training coworkers to handle new tasks, and providing programming support throughout the work unit." —Craig O'Brien, Branch Chief, US Consumer Product Safety Commission (CPSC)
"I worked with Jonathan for a little over two years at the Consumer Product Safety Commission, where he designed computer programs and performed internet research. Jonathan brings to each task an incredible work ethic, creativity, and great technical proficiency. He always performed at a level well above what was expected. For example, he learned SAS (the only programming language at his disposal) on his own so that he could address our branch's complex reporting requirements. Time after time, Jonathan identified ways that workflows and research methods could be improved to increase efficiency and/or accuracy and then developed the necessary computer programs or reference documents to implement the enhanced procedures. I always felt that I could trust Jonathan to find solutions to challenging problems and I am confident that you can too." —Cathy Irish, retired Branch Chief, CPSC
"Jonathan Warren is simply the best researcher you could get for your needs. He is already highly skilled in a full spectrum of relevant technologies, statistical techniques and research methodologies. He is careful in his approach to any problem, and painstakingly thorough in its execution. He is intelligent and learns any new subject quickly. You will not find a more knowledgeable, flexible and capable researcher anywhere on the market." —John C Paolillo, Associate Professor of Informatics and Information Science, Indiana University
