The Graduate Institute of Astronomy at National Central University (IANCU) is seeking qualified candidates for two post-doctoral researchers to work in two different projects. IANCU owns and operates the Lulin Observatory in central Taiwan. IANCU is actively participating in the "intermediate Palomar Transit Factory" (iPTF) project and the "Global Relay of Observatories Watching Transients Happen" (GROWTH) project. IANCU is also expected to join the "Zwicky Transient Facility" (ZTF) in near future. One post-doc position is responsible to robotize the small telescopes at Lulin Observatory in order to meet the observational requirement for GROWTH. The candidate for this position will also need to participate in the research involving asteroids, variable stars and transients using the data from iPTF (and ZTF), GROWTH and LOT. The second position will be focused on the research of variable stars in stellar clusters and local group galaxies. This position requires frequent visits to observatories in Taiwan and around the world for imaging and spectroscopic observations, as well as develop data reduction pipelines. Skills on spectroscopic reductions and extracting radial velocities is strongly preferred. Applicants must have a degree in PhD (or expected to receive PhD before 30 October 2015) during application. The applicants should also have experience and background in observation with optical telescopes and programming (c or python). A good oral communication in Mandarin Chinese is preferred, but not required. Initial duration of the positions is two years, and extendable to third year depending on the performance of the candidates and availability of funding. Please sent a CV, a list of publication and a research plan, together with three reference letters, by email to Chow-Choong Ngeow (firstname.lastname@example.org) before 01 December, 2015, or until the positions are filled. Please indicate which position the candidate is applied for. Starting date is negotiable and can be as earliest as possible. Availability of both (or either one) positions will depends on the outcome of funding.
