Her training includes a residency in Anatomic Pathology, fellowship in Neuropathology, National Library of Medicine Fellowship in Medical Informatics, and a Master's degree in Information Science. Her research interests include: development and evaluation of intelligent medical training systems, computational methods for medical knowledge representation and decision support, information extraction from medical free-text, and empirical studies of the development of visual diagnostic expertise.

Olga Medvedeva, MS, MS grew up in Russia, where she got a Master's degree in astrophysics at Moscow State University and received a second MS degree in radiophysics from the Russian Academy of Science. She came to the United States in 1995 and developed software for the Pittsburgh Advance Cognitive Tutor (PACT) and Carnegie Learning groups at Carnegie Mellon University before joining the SlideTutor team at the University of Pittsburgh in 2001. As lead architect for the project, Olga is responsible for many of the artificial intelligence aspects of the SlideTutor system. Most recently, she as devoted her time to building and evaluating SlideTutor’s student modeling system.

Elizabeth Legowski, BS graduated from Carnegie Mellon University in 2000, where she double majored in Psychology and Statistics. She was previously employed at Carnegie Learning where she helped evaluate the effectiveness of their Cognitive Tutor programs. She joined the SlideTutor project in March 2003 and is involved in multiple projects. Liz provides expertise in study design and analysis, developing user training programs, and HCI evaluation.

Eugene Tseytlin, MS has a BS in Computer Science from Penn State University (2000) and an MS in Computer Science from University of Pittsburgh (2003). Before joining the SlideTutor group, he worked at the Learning Research and Development Center developing medical format conversion software and graphical user interfaces in neuroimaging. He joined the SlideTutor team in October 2003 and since then has developed SlideTutor’s authoring and testing systems. He is the developer of the natural language capabilities of SlideTutor. Most recently, he designed and developed our new virtual slide viewer.

Gilan Saadawi, MD, PhD, MS is an Assistant Professor of Informatics, University of Pittsburgh School of Nursing. Her training includes an MD, Masters and PhD in Clinical pathology from Ain Shams University in Egypt, as well as a Masters degree in Medical Informatics from the University of Pittsburgh School of Medicine, where she was an NLM fellow. Her research interests in the SlideTutor group include HCI abstraction, evaluation of natural language tutoring, and metacognition.

Melissa Castine, BA is the Knowledge Engineer for the SlideTutor project. She graduated from the University of Pittsburgh in 2004 with a double major in Linguistics and Communication Science and Disorders. Before joining the team, she did research with the Communication Science and Disorders Department studying the effect right hemisphere stroke had on language and language processing. She is the author of the SlideTutor domain ontology, and also directs case acquisition and expert image annotation.

Velma L. Payne, MS, MBA has a BS in Computer Science from Oral Roberts University (1984), an MS in Computer Information Systems from Robert Morris University (1996) and an MBA from Robert Morris University (1997). Velma has been a computer programmer for 25 years in the financial and government industries. She is currently pursuing her PhD in Biomedical Informatics in the School of Medicine at the University of Pittsburgh. Her research interests are in determining the cognitive processes clinicians utilize as they make medical decisions. Her current research focuses on measuring cognitive biases and determining the relationship of these biases to a variety of task stimuli. Her long-term research interests include use of technology to reduce medical errors and enhance patient safety. Velma began working with the SlideTutor team in 2006.

Lucy Cafeo is the Administrative Assistant for the SlideTutor project since October 2006. She is responsible for administrative tasks for the group such as assisting with scheduling, grant applications, manuscript submissions, and financial reporting.
