ore than a quintillion bytes of audio and video information is produced around the world each year. For industry, government, education and medicine—all warehousing tons of raw video, there is always a need to exactly locate, from either archived files or live streaming content, audio information that can be quickly retrieved for reference and analysis. The enormous volume of audio recordings demanded new thinking about how to search audio files efficiently.
Shortly after joining MITRE in 2001, Dr. Qian Hu, a compu- tational linguist, came up with the novel idea of building a speech exploitation system. Within a year, Dr. Hu and her research team had developed a prototype tool. Since 2002, Dr. Hu has shown sustained technical and business leader- ship in creating and executing research, including Audio Hot Spotting (2000-2004), Audio Hot Spotting for Tactical and Intelligence Applications (2005-2006), Multimodal Medical Data Capture Representation (2007-2009) and Live Hot Spot- ting of Voice Over Internet Protocol (2008-2009).
Dr. Hu’s Audio Hot Spotting projects have won an Innova- tion Award, the most cost-competitive and coveted technical award at MITRE. Recently, she was awarded a patent for the Audio Hot Spotting method and system she created nine years ago. Audio Hot Spotting is the process of finding “hot spots” within audio files, such as words of interest, speakers, or key sound effects (e.g. laughter, applause, and mechanical noises). The process uses speech-to-text software to process audio files into text, which can then be quickly computer searched for any word or phrase.
Currently, Dr. Hu is developing new approaches to informa- tion access and language processing in the areas of health care, military multimedia search, and communications to improve air traffic safety for both human-piloted and autono- mous aircraft.
Two years later, she graduated top of a University of Ken- tucky master’s degree program in mathematics with a final 4.0 GPA. To further her academic interests, she joined the Air Force Research Laboratory in Dayton, Ohio.
A
Five years on, she is a recognized leader in the development of sensor exploitation technologies. She has published 11 conference papers, an IEEE journal article, and given six con- ference presentations. Some of her most recent are a tutorial on image registration at the 2008 IEEE- Computer Society Conference on Computer Vision and Pattern Recognition, as well as the Advanced Sensors and Sensing Systems session at the 2009 International Society for Optical Engineers, Defense, Security, and Sensing Conference.
When she is not engaged in her professional duties, she is likely volunteering for a community event. A founding mem- ber of Southwest Ohio’s chapter of the Society of Professional Hispanic Engineers, Ms. Mendoza-Schrock’s work with local and minority-serving institutions to expand image registra- tion and tracking algorithm development, has made signifi- cant advances in urban tracking capabilities, while nurturing next generation scientists and engineers to meet the future workforce needs of the Air Force. Over the past three years, she has mentored 10 students – high school to Ph.D. level as well as three university professors.

Ms. Mendoza-Schrock is the 2009 winner of the Meritorious Service Award presented by both the U.S. Department of De- fense and the National Organization for Mexican-American Rights. The award was given in recognition of her exceptional meritorious service as a research mathematician for the Air Force.
