• December 15, 2016: Dr. Li An traveled to Fanjingshan National Nature Reserve (FNNR) between December 4 and 9. He met FNNR leaders and friends Director Zhang, Deputy Direcors Lei and Yang, Secretary Yang, and other people; both FNNR leaders and Dr. An show strong interest in continuing our partnership in research, education, and outreach in the future. Accompanied by Lei Shi, Haibo Li, and/or Qifang Li, Dr. An visited villages close to the former golf course project, Pianyan Resevoir, and Liziyuan Resevoir, and interviewed local villagers. The left photo was taken at Jinchang ELementary School and the right one at the previous golf course site.

• August 30, 2016: Warmest welcome to two new master's students Evan Casey and Judy Mak! Judy received her degree in Earth System Science from UC Irvine, and Evan his degree in Geography from San Diego State University. Welcome to join the SDSU Geography Department and the CHES group!

• August 19, 2016: Master's student Curtis Battle successfully defended his thesis ¡°Sex specific habitat models for Bengal tigers in Chitwan National Park, Nepal" on Aug 19th. His research showed that the probability of occurrence of male tigers was positively affected by prey abundance and water resources while occurrence of female tigers were affected by more variables, including human settlement and vegetation. The results highlight the importance of considering sex in habitat models and have significant contributions to conservation and management of Bengal tigers. Congratulations Curtis!

• May 12, 2016: Dr. Li An organized a successful symposium and presented at The International Society for Ecological Modeling Global Conference 2016 (8-12 May 2016, Baltimore, Maryland). He also served as a member of the conference's Scientific Steering Committee and gave a talk titled ¡°Modeling human decision-making and their interactions with the Guizhou Golden Monkey habitat use". Read more about this event.

• April 29, 2016: PhD candidate Shuang Yang was recently awarded the Caldwell, Flores, and Winters Award in GIS Emphasizing Human Geography Applications for the 2016-17 academic year. Shuang creatively employed GIS technologies to solve human livelihood problems at Fanjingshan National Nature Reserve (China), which hugely supported Dr. An's NSF project "Impacts of Ecosystem Service Payments in Coupled Natural and Human Systems". He also creatively developed a set of google earth protocols to map human environmental use patterns in areas without Internet access, which made a big advance in understanding local FNNR people's resource use patterns. Congratulations Shuang!

• April 29, 2016: Master's student Jeanne Patton was recently awarded the McFarland Geography Scholarship for the 2016-17 academic year. According to Rose Pasenelli, Director of SDSU Office of Financial Aid and Scholarships, this scholarship is annually given to eligible students who meet all scholarship requirements, such as units enrolled, major, and GPA. Congratulations Jeanne!

• April 13, 2016: Invited by the Department of Mathematics & Statistics, Dr. Li An gave a statistics seminar based on his NSF, NASA, and NIH funded projects.

This "leadership" project aims to organize a workshop under the goal of transforming the science, technology, and application of agent-based models (ABMs, or agent-based modeling¡ªABM) in the context of social, human-environment, and life sciences. If funded, over forty two exceptional agent-based modelers and/or ¡°users¡± (ranging from junior scholars such PhD students and postdoctoral fellows up to members of the National Academy of Sciences) of these models will come together and hash out strategic plans and actions to advance the science of agent-based modeling.
