He is one of the main developers of the Image Guided Surgery Application (IGSTK) toolkit, a cross platform, open-source C++ software library that provides basic components needed to prototype image-guided surgery applications. He has been a principal investigator and co-investigator of several research grants and he has lead several commercial projects.

In his leadership role, Dr. Enquobahrie builds and maintains research relationship with external collaborators. He explores funding opportunities, prepares competitive proposals and leads a team of scientists and research and development engineers working on cutting-edge research in the field of medical computing at Kitware. Dr. Enquobahrie received his PhD degree in Electrical and Computer Engineering from Cornell University. He has an MBA from Poole College of Management at North Carolina State University with an emphasis in innovation management, product innovation and technology evaluation and commercialization. Dr. Enquobahrie has authored or co-authored more than 40 publications in image analysis, visualization and image-guided intervention area. Dr. Enquobahrie serves as a program committee member for SPIE Medical Imaging and Computer Assisted Radiology and Surgery (CARS) conferences. He has been serving as a technical reviewer for several medical image analysis and image-guided intervention journals including Medical Imaging Computing and Computer Assisted Intervention (MICCAI), Computer Methods and Programs in Biomedicine, Academic Radiology, Journal of Digital Imaging, IEEE Transactions on Medical Imaging, IEEE International Conference on Robotics and Automation.
