DR. QUN ZHANG'S ACADEMIC WEBPAGE

ACADEMIC BIOSKETCH
Qun Zhang earned a PhD in chemical physics from the University of Science and Technology of China (USTC) in 1999. After a seven-year stint as a postdoctoral fellow & research associate with Prof. Moshe Shapiro at the Weizmann Institute of Science (2000–2003) and the University of British Columbia (2003–2007), he joined USTC working initially on gas-phase molecular spectroscopy & reaction dynamics [with 30 papers (as a PI) published in peer-reviewed journals]. Since 2011, he has been devoted to establishing a USTC Ultrafast Laser Laboratory (UULL) from scratch and then focusing his research on condensed-phase ultrafast spectroscopy & dynamics. In this topical field, he has authored 86 papers (as a PI) in peer-reviewed journals [including 50 in the Nature-Index Journals: Adv. Mater. (8), Angew. Chem. Int. Ed. (9), Appl. Phys. Lett. (1), Chem. Commun. (2), Chem. Sci. (1), Inorg. Chem. (1), J. Am. Chem. Soc. (10), J. Phys. Chem. Lett. (14), Nano Lett. (1), Nat. Commun. (1), Phys. Rev. Lett. (1), Sci. Adv. (1)]. As of January 2024, the total citation of his journal publications is 11000+ with an H-Index of 43. Currently, he holds a position of chair professor at USTC and is an adjunct PI in Hefei National Research Center for Physical Sciences at the Microscale & Hefei National Laboratory (HFNL). He has been admitted as a Fellow of International Association of Advanced Materials (FIAAM, 2022) in recognition for his contribution to "Analytical Methods and Spectroscopy".

TEACHING ACTIVITIES

• Chemical Dynamics I (Module #1 of the modulized course "Chemical Dynamics"; CHEM5003P for postgrads; Spring semester)
  Questions about the rates of processes and about how reactions take place are the purview of chemical kinetics and molecular reaction dynamics. Because this subfield of physical chemistry is the one most concerned with the "how, why, and when" of chemical reaction, it is a central intellectual cornerstone to the discipline of chemistry. And yet it is of enormous practical importance as well. In this 2-credit course, we begin with examining the motions of gas-phase molecules in Chapter 1 ("Kinetic Theory of Gases"), and then examine in Chapter 2 "The Rates of Chemical Reactions". In Chapter 3 ("Theories of Chemical Reactions") we look at reaction rates from a more microscopic point of view, drawing on quantum mechanics, statistical mechanics, and thermodynamics to help with understanding the magnitude of chemical rates and how they vary with both macroscopic and microscopic parameters. This course is suitable for the third-year undergraduate level or above, as well as for the first-year grads. Throughout this course we would like to place emphasis on fundamental concepts rather than just deliver as much material as possible; nevertheless, rigorous mathematical treatment cannot be and should not be avoided if we are to give precision to the basic principles.

• Chemical Dynamics IV (Module #4 of the modulized course "Chemical Dynamics"; CHEM6011P for postgrads; Spring semester)
  The integration of ultrafast spectroscopy with chemistry and materials science has greatly propelled their development, as the key information gleaned from the mechanistic studies with the assistance of ultrafast spectroscopy enables a deeper understanding of the structure–function interplay and various interactions involved in the complex, condensed-phase, chemical and material systems. Armed with these critical, mechanistic insights, one can step further to steer the chemical systems to desired directions (e.g., by means of coherent control) or to optimize the design of material systems for achieving better performances. In this 2-credit course, we begin with briefing the history of time-resolved spectroscopy in Chapter 1, and then introduce in Chapter 2 the basics and principles of femtosecond laser techniques. In Chapter 3 we deliver the key concepts of ultrafast transient spectroscopy, addressing several important time-domain features encoded in the spectra as well as some photophysical/photochemical processes. A variety of techniques and methods used in ultrafast transient spectroscopy are described in Chapter 4. Armed with the fundamental materials of the first four chapters, we move forward to the exciting area of ultrafast spectroscopy and dynamics in condensed phases, with a focus on exploring the underlying mechanisms in the complex, chemical and material systems (Chapter 5). This course is suitable for the third-year undergraduate level or above, as well as for the first-year grads. Throughout this course emphasis is placed on fundamental concepts/principles as well as realistic practices at the forefront of the research field.
