Janine Zacharia
Lecturer
Current Research and Scholarly InterestsInterested in new forms of foreign correspondence, how stories go viral, the intersection between technology/social media and national security. Middle East/Israel is my main area of reporting expertise.

Jamil Zaki
Professor of Psychology
Current Research and Scholarly InterestsMy research focuses on the cognitive and neural bases of social behavior, and in particular on how people respond to each other's emotions (empathy), why they conform to each other (social influence), and why they choose to help each other (prosociality).

Current Research and Scholarly InterestsMy research group is exploring a variety of topics that range from the basic understanding of chemical reaction dynamics to the nature of the chemical contents of single cells.
Under thermal conditions nature seems to hide the details of how elementary reactions occur through a series of averages over reagent velocity, internal energy, impact parameter, and orientation. To discover the effects of these variables on reactivity, it is necessary to carry out studies of chemical reactions far from equilibrium in which the states of the reactants are more sharply restricted and can be varied in a controlled manner. My research group is attempting to meet this tough experimental challenge through a number of laser techniques that prepare reactants in specific quantum states and probe the quantum state distributions of the resulting products. It is our belief that such state-to-state information gives the deepest insight into the forces that operate in the breaking of old bonds and the making of new ones.
Space does not permit a full description of these projects, and I earnestly invite correspondence. The following examples are representative:
The simplest of all neutral bimolecular reactions is the exchange reaction H H2 -> H2 H. We are studying this system and various isotopic cousins using a tunable UV laser pulse to photodissociate HBr (DBr) and hence create fast H (D) atoms of known translational energy in the presence of H2 and/or D2 and using a laser multiphoton ionization time-of-flight mass spectrometer to detect the nascent molecular products in a quantum-state-specific manner by means of an imaging technique. It is expected that these product state distributions will provide a key test of the adequacy of various advanced theoretical schemes for modeling this reaction.
Analytical efforts involve the use of capillary zone electrophoresis, two-step laser desorption laser multiphoton ionization mass spectrometry, cavity ring-down spectroscopy, and Hadamard transform time-of-flight mass spectrometry. We believe these methods can revolutionize trace analysis, particularly of biomolecules in cells. -

Mayshu Zhan
Ph.D. Student in Modern Thought and Literature, admitted Autumn 2023
Ph.D. Minor, Computer ScienceCurrent Research and Scholarly InterestsMy interdisciplinary research examines digital media through the lens of critical race, gender, and sexuality studies. I am primarily interested in investigating how we can leverage the power of media to reinvent and promote social equality. Specifically, my research focuses on digital games and their prosocial influence on 21st- century China.

Xiangqian Zhang
Affiliate, Archaeology
Visiting Scholar, ArchaeologyBioThe main directions of work and research are as follows:
1、The Sustainable development of cultural heritage sites, the process of protecting and managing cultural heritage in a way that ensures the rational use of resources, the equitable distribution of socio-economic benefits, and the maintenance of cultural authenticity and environmental sustainability. It involves balancing economic, environmental and socio-cultural interests to ensure that cultural heritage is effectively protected and rationally utilised in the long term;
2、Digital restoration and exhibition of artifacts,the restoration and protection of cultural relics using modern digital technology, and presenting the original appearance of cultural relics and related information to the public through virtual display. This includes the use of high-definition scanning, three-dimensional modeling,image processing and other technical means to digitally reconstruct damaged cultural relics, and at the same time, through the Internet, Virtual Reality (VR), Augmented Reality (AR) and other platforms, to allow viewers to appreciate and learn the historical and cultural values of cultural relics without touching the physical objects. -
