Ultrafast Dynamics
Research Field
Dr. Chung-Hsin obtained his Ph.D. from the Department of Molecular and Laser Physics, Radboud University Nijmegen, The Netherlands. Later, he moved to FOM Institute AMOLF (Amsterdam, The Netherlands) and Max-Born-Institute (Berlin, Germany) to conduct postdoctoral research. Afterward, he returned to Taiwan to conduct another postdoctoral research at the Institute of Atomic and Molecular Sciences, Academia Sinica, Taiwan. In 2020, he began his independent research career as an Assistant Professor of the International PhD Program for Science at National Sun Yat-sen University. He also holds a joint appointment in the Department of Chemistry at National Sun Yat-sen University.
We study photodissociation and photocatalytic synthesis mechanisms by various ultrafast spectroscopic techniques, including pump-probe transient absorption and photoion/photoelectron imaging. The acquired transient intermediates, excited-state lifetimes, and product energy distributions help understand the underlying photophysics and photochemistry.
1. TRACKING COMPLEX PHOTOINDUCED DYNAMICS FROM ATMOSPHERIC MOLECULES AND AEROSOLS BY TIME-RESOLVED SPECTROSCOPY.
2. EXPLORING THE INTERMEDIATES AND REACTION MECHANISM OF PHOTO-CATALYTIC SYNTHESIS using transient absorption spectroscopy.
3. LIGHT-INDUCED PARTICLE FORMATION and advanced microscopy.

Senior undergraduate (strong lab background), M.S. student, or early-stage Ph.D. student in Chemistry, Physics, Materials Science, or related fields.
Skill sets or Qualities
1. Basic optics/spectroscopy concepts.
2. Quantitative data handling and analysis.
3. Careful, methodical experimental habits; strong documentation discipline.
4. Ability to communicate clearly and work in a collaborative, international lab setting.

Job Description
1. Assist with experiment setup and measurements in the nanosecond–microsecond regime and/or complementary detection workflows (photoion/photoelectron signals depending on project).
2. Perform spectral assignment support: build reference libraries, compare datasets across conditions (wavelength, fluence, environment), and identify product/intermediate signatures.
3. Develop analysis pipelines for time traces and distributions (e.g., kinetic modeling, rate extraction, comparative mechanistic tests).
4. Summarize findings in concise figures and short reports suitable for group discussion and potential publication support.
Preferred Intern Educational Level
M.S. student or Ph.D. student (preferred), or exceptionally strong senior undergraduate with prior spectroscopy/physical chemistry research experience.
Skill sets or Qualities
1. Physical chemistry fundamentals (kinetics, spectroscopy; basic potential energy surface intuition).
2. Data-analysis capability.
3. High attention to detail, patience with instrumentation, and strong safety compliance.
4. Curiosity-driven problem solving; willingness to learn new experimental/analysis techniques.
5. Professional communication and reliability.
