Activities and achievements of CHES members

• June 06, 2017: Congratulations to Jie Dai, whose proposal "Mapping and Modeling the Invasion of Mikania Micrantha in the Chitwan Community Forests, Nepal: A Coupled Human and Natural Systems Approach" was selected for the very prestigious NASA Earth and Space Science Fellowship (NESSF) for two years (2017-2019)! According to NASA program officer Dr. J.A. Kaye, this fellowship is very competitive and only the top 18% candidates were selected this year. Good job well done Jie!

• May 22, 2017: Dr. Li An had a successful trip to several Chinese sites for combined research and family purposes between May 4 and May 19, 2017. He visited scholars at Capital Normal University and the Institute of Remote Sensing and Digital Earth of the Chinese Academy of Sciences in Beijing, initializing new collaboration opportunites. He also visited Fanjingshan National Nature Reserve (FNNR) in Guizhou Province and did a couple of experiments regarding the use of unmanned aerial vehicle (UAV)-borne thermal infrared (TIR) sensors in detecting wild animals.

• April 22, 2017: The CHES group had a very successful symposium, which generated lots of excitements. See this site for more detail.

• March 15, 2017: Congratulations to Jie Dai, who successfully completed his oral exam (he passed his written exams in January 2017). All his committee members, Drs. Dar Roberts (UCSB), Phaedon Kyriakidis (UCSB), Doug Stow, and Li An unanimously passed Jie's written exams as well as his oral exam/dissertation proposal titled "Community Forestry in Chitwan Valley, Nepal - Challenges with the Invasion of Mikania micrantha". He has thus moved to PhD candidacy. Nice job well done Jie!

• March 06, 2017: Dr. Li An presented his research entitled "The Invisible Hand in Complex Human-Environment Systems" at the Department of Biology Seminar Series. The seminar consists of three major stories: the story of 1+1 < 2, the story of neighborhood, and the story of time. The well attended seminar was followed by great questions from faculty, staff, visitors, and graduate students and a pizza luncheon with graduate students (Here is the abstract of the presentation).

• February 22, 2017: Dr. Li An presented his research entitled "Payments for Ecosystem Services (PES): 1 + 1 < 2?" at the SDSU Discovery Slam. The discovery slam was held at the Gold Auditorium in the SDSU BioScience Center between 5 pm and 6:30 pm. Co-sponsored by Steve Welter (Vice President and Dean of Graduate and Research Affairs), Stanley Maloy (Dean of College of Sciences), and SDSU Research Foundation, the slam aims to provide "an enjoyable venue for faculty, administrators, and staff to learn about a variety of different research topics ĘC generating broader awareness of research accomplishments across the campus and possibly generating interdisciplinary collaborations" (quote from Stephen Welter). According to the thank-you message from Dr. Maloy, "...You made some great points about your research and research in general. There was a great response from the audience." See more detail here.

• January 31, 2017: After careful search and comparison among candidate hotels, the ABM 17 team has decided that the ABM 17 symposium will be held at San Diego Marriott Mission Valley. More detail about lodging is available here. See this site for more informaiton about the call for participation.

• January 20, 2017: Invited by Drs. Hui Lin, Xun Shi, and Xinyue Ye (Editors), Dr. Li An and docotoral student Jie Dai wrote and submitted a chapater about space-time analysis for a book tentatively entitled "Frontiers of Geographic Information Science" (in Chinese). For more detail see the invitation letter.

• January 03, 2017: As the lead PI of Project ABM 2017: Agent-Based Models in the Social, Human-Environment, and Life Sciences, Dr. Li An has been organizing the symposium with help from his science committee, SDSU Geography staff, and his students. More details can be obtained at the project's news and announcements sections.
