Human Technology Interaction Lab
Research falls at the intersection of physiological computing and Human-Computer Interaction (HCI). Current research activities aim to expand knowledge regarding ways to design, implement and evaluate novel physiological computing systems that enhance usability and user experience (UX). This work involves designing adaptive closed-loop systems that interpret users’ affective states using neurophysiological signals such as Electroencephalography (EEG). Ongoing research is also exploring ways to abstract low-level signal processing procedures to address barriers of entry to areas of physiological computing. This work also involves investigating ways to introduce novice programmers to physiological computing concepts. A usability lab equipped with an observation room and experiment area is used to evaluate human interactions with these novel systems.

Data Mining Lab
The world is experiencing a remarkable growth in the amount of data coming from various sources. These data are generated by physical sensors, such as traffic camera streams and seismometer signals, and by humans, such as social media posts, news articles, scientific publications, and blogs. The Data Mining Lab’s research interests are driven by a motivation to mine these data for addressing real-world, socially meaningful problems. Current areas of interest include disaster management, transportation and mobile health.

Spatial Data Science Lab
Spatial data science is a field that lies at the intersection of data science and geospatial information science, and studies how to identify patterns or make predictions from massive spatial data. With the advancement of GPS and remote sensing technology, and the popularity of mobile devices, large amounts of geospatial data are being collected at an increasing speed. Analyzing such data assets is already transforming the society in environment management, disaster response, and transportation. The lab’s mission is to investigate effective and efficient data science techniques, particularly focusing on spatial or spatiotemporal data, in the context of societally significant applications. The team currently investigates spatial prediction models, spatial pattern analysis on networks, and spatial big data computation with interdisciplinary applications in hydrology, transportation, and public safety.

Software Engineering Research Group
Key areas of interest include empirical software engineering, model-driven engineering, and human factors. Research in empirical software engineering seeks to use empirical methods to gather quantitative and qualitative data to characterize, understand, and evaluate the software engineering process. Ongoing projects focus on improving the development of open-source software and understanding how to properly apply software engineering practices to the development of research software. Research in model-driven engineering seeks to reduce the gap between the problem domain and the solution domain by modeling all aspects of the software system with concepts from the problem domain, instead of source code. Ongoing projects focus on applying software engineering techniques such as transformation, simulation, analysis, and evolution to software and systems models. Research in human factors seeks to understand and eliminate barriers faced by the people in the software engineering process. Ongoing projects focus on understanding human error in requirements and studying the effects of social debt on software development.

Computer Science Education
Research in Computer Science Education focuses on pedagogical techniques for computer science that are applicable to students and teachers from the K-12 grades through higher education. A core area of K-12 focus is the investigation of professional development models for training in-service and pre-service teachers as future computer science educators. Other topics of interest in the K-12 space include the design of block languages for introducing programming, tool support for children with accessibility needs, and curriculum development that addresses broadening participation in computing for underrepresented students. At the university level, research includes topics related to pedagogical techniques for software testing and training Computer Science Education researchers on proper empirical methods.

Distributed Autonomy Laboratory
Research focuses on using teams of robots to accomplish high-level tasks. Appropriate shared representations and communications paradigms are tested in simulation and in a lab environment. Collaborations exist between software engineering, behavioral science and networking. Research includes the study of appropriate multi-robot experimental frameworks through evaluation of measurement tools, software architectures and development and simulation environments. A specialized testing facility is instrumented with ground truth localization and image systems for data collection.
