Ph.D., University of Southern California, 1981
School of Communication, SDSU

Dr. Spitzberg is an expert in communication assessment and interpersonal communication. He will conduct qualitative surveillance and identification of social issues that could provide logical topics of relevance to meme diffusion and social influence.

Brian H. Spitzberg (Ph.D., University of Southern California, 1981) is Senate Distinguished Professor in the School of Communication at San Diego State University. His areas of research include interpersonal communication competence, communication assessment, communication theory, conflict, jealousy, infidelity, intimate violence, sexual coercion, and stalking. He teaches in the areas of communication theory, risk and crisis communication, interpersonal communication, and the dark side of communication. He is author or co-author of 3 scholarly books, co-editor of 3 scholarly books, and author or coauthor of over 100 scholarly articles and chapters, including the award-winning book written with William Cupach on The Dark Side of Relationship Pursuit: From Attraction to Obsession and Stalking. He also an active member of the Association of Threat Assessment Professionals.


Co-PI:   Dr. Jean Mark Gawron (Linguistics, SDSU)

Ph.D., University of California at Berkely
Department of Computational Linguistics, SDSU

Dr. Gawron has over 25 years experiences in computational linguistics and machine translation research. He will be in charge of language analysis for social media messages and be responsible for creating ontologies, information extraction systems, and text classifiers trained on computational linguistic methods. One linguistics master student will work with Gawron.

Dr. Jean Mark Gawron is a computational linguist with 30 years of experience in the field. His areas of research have been logic, logical semantics, parsing, and lexical semantics. In this project he is using dependency parsed data to create distribution vectors for all words and experimenting with Lin’s sim measure (Lin 1998), cosine, and Latent semantic indexing (Deerwester 1990) as measures of similarly between words, which in turn will help build thesauri and ontologies. He is also experimenting with using a cluster of factors involving _citation_analysis_ as a component of the web page classification model. Citation analysis is the study of patterns of reference by authors to other authors and texts. As a field it predates the web (Garfield 55 Pinski and Narin 1976).


Co-PI:   Dr. Jay Lee (Geography, Kent State)

Phone: 330-672-3222
Ph.D., University of Western Ontario
Department of Geography, Kent State University

Lee has extensive experiences in developing and calibrating simulation software for geographic phenomena, including urban growth simulator and urban crime simulator. He will lead the development of agent-based models to simulate how memes flow over different network configurations and associated spatiotemporal processes.

Jay Lee is Professor of Geography at Kent State University in Ohio. His research interests include geographic information sciences, geospatial analysis, and Geosimulations. PhD in Geography from The University of Western Ontario (London, Ontario, Canada). Jay has taught a suite of courses in GIScience since 1989. His research interest stems from a broader effort to apply methods and tools in operations research to GIS. In recent years, Jay has received funding for research projects in the areas of simulating urban growth (US EPA), air/nonpoint source pollutions (US EPS) as induced by urban growth, and changes in crime rates as induced by urban growth (NIJ). His recent works include developing quantitative methods for modeling spatio-temporal diffusion processes.


Co-PI:   Dr. Ruoming Jin (Computer Science, Kent State)

Phone: 330-672-9063
Ph.D., Ohio State University
Computer Science Department, Kent State University

Dr. Jin is an expert in Big Data and Social Network Analysis. He will lead the efforts in developing predictive models and influence maximization algorithms to understand and predict the spreads (speed, scale, range) of meme in the social network with spatial, temporal, and topic constraints. One Ph.D. student in computer science will work with Jin.


Senior Personnel:   Dr. Xinyue Ye (Geography, Kent State)

Phone: 330-672-4304
Ph.D., University of California Santa Barbara and SDSU
Department of Geography, Kent State University

Dr. Ye is an expert in spatiotemporal analysis. He will conduct space-time analysis and modeling on the dynamics of information landscape and the meme diffusion across networks, as well as the driving forces underlying memes network flow.



Senior Personnel:   Dr. Xuan Shi (Geoinformatics, U of Arkansas)

Phone: 479-575-7906
Ph.D., University of West Virginia
Department of Geosciences, University of Arkansas

Dr. Xuan Shi is a GISscientist with expertise in geocomputation, spatial data mining and analytics, and parallel and distributed computing using GPU and MIC clusters. He will work on the optimization of computation programs in this project for data mining, social media analytics, and visualization with a very large scale of heterogeneous datasets.


Senior Personnel:   Dr. Heather Corliss (Public Health, SDSU)

Phone: 619-594-3470
Ph.D., University of California Los Angeles
Division of Health Promotion and Behavioral Science, SDSU

Dr. Heather Corliss is an expert in behavioral and social epidemiology. She has extensive training in quantitative and qualitative research methods for studying behavioral health. Dr. Corliss will develop and implement behavioral theory analysis methods and predictive models for studying social media messages and identify the applicability of behavioral theories for understanding meme diffusion.

Dr. Corliss is an Associate Professor in the Graduate School of Public Health at San Diego State University. She received her MPH in community health sciences and her Ph.D. in epidemiology from UCLA, completed a postdoctoral fellowship in health disparities research at Boston Children’s Hospital, and was an Assistant Professor of Pediatrics at Harvard Medical School before coming to SDSU in Fall 2013. Her primary area of research, funded by NIH, is focused on understanding health disparities based on sexual orientation and gender identity and the effects of social stigma on health behaviors and chronic health.
