Brian Hu, Ph.D., is a staff R&D engineer on Kitware’s Computer Vision (CV) Team located in Arlington, Virginia. He provides research direction and guidance in the areas of explainable AI (XAI), human-machine teaming, image retrieval, and object detection. In support of the CV Team, Brian is actively involved in developing new models and algorithms, running experiments, and writing papers.
On the Defense Advanced Research Projects Agency (DARPA) XAI program, Brian developed novel saliency algorithms for image retrieval and anomaly detection and applied them to the medical imaging domain. He was also involved in the United States Special Operations Command (SOCOM) XQHM project where he helped design user studies to improve Kitware’s interactive query refinement platforms. For the Air Force Research Laboratory (AFRL) DIYAI effort, Brian is working on improving small object detection by incorporating spatial context and motion cues.
Prior to joining Kitware, Brian was a research scientist at the Allen Institute for Brain Science where he worked on data analysis and computational modeling of neural and behavioral data, biologically-plausible neural networks, and short-term memory mechanisms. His work in the neuroscience domain has been featured in several journals and at conferences such as the IEEE Conference on Information Sciences and Systems (CISS).
Brian received his Ph.D. in biomedical engineering from Johns Hopkins University. He received his bachelor’s degree in biomedical engineering from the University of Pittsburgh.
