In addition to my appointment in Geographical and Sustainability Sciences, I am a cluster faculty at Iowa Informatics Initiative (UI3) and a coordinating committee member for the Geoinformatics program.
To Prospective Graduate Students:
I am looking for MS/PhD or PhD students starting from Fall 2018. Desirable research interests are (but not limited to):
- Spatial network analysis (e.g., network measures, community detection, spatial interaction modeling, diffusion models)
- Spatial data mining (e.g., clustering, association rule mining, classification, machine learning, and deep learning for object classification)
- Geovisual analytics and human computer interaction (e.g., interactive cartography, flow mapping, coordinated views, utility and usability evaluation)
- Big data analytics for social media and networking applications (e.g., natural language processing, topic modeling, sentiment analysis)
- High performance computing, Hadoop, and big data storage systems (MongoDB)
- Application areas such as human migration and mobility, geographically-embedded social networks (e.g., interpersonal communication, family tree), patient mobility, human communication, transportation, and energy networks; movement and pass networks in sports (e.g., soccer, basketball); analysis of social media data; social sensing and networks for disaster response, recovery and resilience
In addition to research interests, following skills are desired:
- One of the programming languages such as Java, C++, or Python;
- Statistical computing such as R or Matlab
- GIS Software such as ArcGIS or QGIS.
- Database management systems such as Postgresql, PostGIS, and MongoDB
- English Proficiency (TOEFL)
Upon admittance you will be a member of The Geo-Social Lab, which is home to research projects aimed at developing innovative computational and visual tools to better understand and analyze massive and complex geo-social networks.
We offer Master's and PhD degrees both at the Department of Geographical and Sustainability Sciences, and the interdisciplinary program at Geoinformatics. I recommend students with Computer Science background to apply to the program in Geoinformatics. Graduate teaching and research fellowships, and assistantships are available for competitive students. Before applying, please contact me with your brief research interests and CV attached. Visit The GeoSocial Lab website and read my publications below to learn more about my research. Below is a video recording of an invited seminar I gave in the Department of Biostatistics. The seminar was about the application of spatial data mining methods for the analysis of big and longitudinal patient mobility data.
I invite competitive students for a Skype interview. The interview starts with a 6 minute, 40 second, a Pecha Kucha style presentation focused on your background, skills, and research interests.
