Leslie Blaha is a Senior Cognitive Scientist in PNNL’s National Security Directorate. Leslie imagines a future where Smart Adaptive Interfaces will transform the way we use cognitive models to support and enhance human decision making, not just to study cognitive behaviors in laboratories.  

Dr. Shari Matzner joined PNNL as a graduate intern in 2007 and is now a senior research engineer at PNNL’s Marine Sciences Laboratory.  Prior to joining the lab, she worked as an engineer in the space program at NASA’s Johnson Space Center, developing applications to support the astronauts aboard the space shuttle and developing space station simulators for training ground controllers. 

Karen is a Scientist in the Data Sciences & Analytics Division at PNNL. She joined PNNL in February 2016 from Noblis, Inc., a not-for-profit science and engineering government consultancy where she worked as a biodefense subject matter expert and program manager.

Dr. Dustin Arendt, Ph.D., is a senior visualization scientist in the Visual Analytics group at PNNL, joining the Laboratory in October 2014.

Dustin’s research interests covers the intersection of machine learning, networks, and visual analytics, with a particular focus on novel and intuitive ways to communicate dynamism in complex changing systems. He is pioneering novel and scalable techniques for using storylines to visualize dynamic structure in networks and other forms of data.

Dr. George Chin, Ph.D., is a Chief Scientist in the Visual Analytics Group at PNNL. George has brought in and led a wide array of research and development projects in the areas of graph analytics, visual analytics, and machine learning for DOE and DoD clients. His most recent research work is focused on streaming dynamic graph analytics, where he is developing scalable methods for identifying cyberattack patterns in real-time computer network traffic, constructing probabilistic graphical models for tracking potential network attack vectors based on software vulnerabilities, and utilizing innovative temporal and geospatial graph metrics to identify leaders (or rabbits) and followers (or wolves) in co-location networks.

Nick Cramer received his Computer Science degree from Central Washington University in 2001. Nick joined the Department of Energy's Pacific Northwest National Laboratory as a visual analytics researcher in 2001. His primary training and interest are in visual analytics, including extensive experience in information visualization, text analytics, and software engineering.

Lyndsey Franklin joined PNNL as a software developer in October 2007. She works in User Experience and Design as part of the Visual Analytics group.

Lindsey's current focus is on understanding the Sensemaking process as a part of streaming data environments.

Dr. Nathan Hodas, Ph.D. is a Senior Research Scientist in the Data Science and Analytics group at PNNL.

Nathan's research interests include behavioral modeling, social media analytics, machine learning, and physical modeling. He has significant experience connecting complex and messy real-world data with analytical models of physical, biological, and human systems.

William Smith has more than ten years of experience as a software industry professional with success directing a range of initiatives while participating in the planning, analysis, and implementation of software frameworks. 

Dr. Abhinav Vishnu, Ph.D. is a senior research scientist at PNNL.
