John Horgan is a Professor in the Global Studies Institute and Department of Psychology at Georgia State University. He has a PhD in applied psychology and his research focuses on understanding psychological qualities of the pathways into, through, and out of terrorism.
Professor Horgan is one of the world’s leading experts on terrorist psychology and his current research examines the psychology of religious converts and their involvement in violent extremism, and the processes by which children become involved in terrorist organizations. His work is widely published, with books including The Psychology of Terrorism, Divided We Stand: The Strategy and Psychology of Ireland’s Dissident Terrorists; Walking Away from Terrorism, Leaving Terrorism Behind, and Terrorism Studies: A Reader. He is Editor of the journal Dynamics of Asymmetric Conflict and serves on the Editorial Boards of several further journals, including Legal and Criminological Psychology, Terrorism and Political Violence, Studies in Conflict and Terrorism and Journal of Strategic Security.
Dr. Ning Fang joined Georgia State University in August of 2008 as an Assistant Professor. He received his B.S. from Xiamen University, China in 1998 and his Ph.D. from the University of British Columbia, Canada in 2006 under Prof. David D.Y. Chen and was a Postdoctoral Associate at Iowa State University and Ames Laboratory, U.S. Department of Energy with Prof. Edward S. Yeung from 2006 to 2008.
Dr. Fang has developed a new optical imaging technique, Single Particle Orientation and Rotational Tracking (SPORT), to image rotational motions in live cells and ultimately target cancer cells.
Dr. Fang’s invention is a differential interference contrast (DIC) microscopy-based imaging tool, which tracks plasmonic nanoparticles of various shapes and sizes. The SPORT is a modified commercial microscope with five-dimensional single- particle tracking capabilities.
The SPORT enables scientists to acquire fundamental knowledge about the detailed rotational dynamics of cellular processes, such as adhesion, endocytosis and transport of functionalized nanoparticles relevant to drug delivery and viral entry. Dr. Fang received the prestigious Innovation Award from the Federation of Analytical Chemistry and Spectroscopy Societies for this invention.
The SPORT helps answer this question, providing insight into nanoparticle-protein and cell interactions specifically related to cell migration.
The next step for Fang and his research team is to develop computer stimulations to understand the effects of nanoparticle shapes, sizes and surface modifiers.
His work in is funded by the National Institutes of Health and the National Science Foundation.
I am an anthropological archaeologist, so I am trained to ask big questions about human societies through the material record people left behind – people’s trash is a treasure trove for archaeologists! My ongoing research examines how people are affected by major changes to the social and political organizations they live in. Many archaeologists have asked this question in the context of colonization or imperial expansion – how, for instance, was your life affected if your community was conquered by the Roman Empire. That’s important of course but I’m interested in the flip side of that – how does the collapse of a political organization, especially a political state, affect its members? If you’re a regular person, living your daily life, and the state you live under breaks down, does that have an impact on you and if it does how do you and your community respond?
Our research focuses on the development and application of optical imaging techniques in chemical and biological research. We currently have three projects funded by NIH and NSF to seek answers to the following fundamental questions: (1) How do molecular motors (e.g., dynamin and kinesin) carry out the essential cellular functions, such as endocytosis and intracellular transport? (2) What are the underlying mechanisms of the profound effects of nanoparticles on cytotoxicity, human health, and environments? (3) How do we quantitatively study the catalytic efficiency of nanocatalysts at the single molecule and single catalyst level?”
I grew up in the United Kingdom as it was joining the EU, and I think this really inspired my interest in how big changes in political organization (in that case becoming part of a bigger political system) affected people’s lives. While I haven’t personally lived through a political collapse, we do know that this is something that happens recurrently in human societies – there are numerous examples in the distant past (e.g. the Roman Empire) but also more recently (e.g. Somalia). Collapse will continue to happen and continue to impact people’s lives. Therefore, it’s a process that we need to understand, in part so we can anticipate how future collapses will play out.
Our work makes an impact in both basic science and biomedical applications. We provide new fundamental knowledge about the detailed rotational dynamics of cellular membrane processes, such as adhesion, transport, and endocytosis of functionalized nanoparticles, as may be relevant to drug delivery and viral entry. We make the first accurate measurement of the nanoconfinement effects on catalysis and provide guidance to improve the efficiency of nanocatalysts. We study nanoparticles of different sizes and shapes and explore their biomedical application in inhibiting cancer metastasis.
I regularly teach ‘Introduction to Anthropology’ (ANTH 1102). Anthropology is very rarely offered in high school so for most students this is the first exposure they’ve had to Anthropology. Many have never even heard of it before they take the class. So, we start with the fundamentals – that Anthropology is the study of humans. The scope of that class is huge! We examine human origins or where we come from, we consider how the way we organize our communities has changed through time and why that has led to the world we live in today, we look at major milestones in our past (like when our ancestors first started to create art or adorn their bodies with jewelry), and we talk about challenging issues – such as race, gender, class – that impact peoples’ experience of the world on a daily basis.
I teach a course on chromatography. Challenging theories are discussed in the beginning of the semester. The “aha!” moment arrives when we connect the theories to practical separation techniques. All of a sudden, everything seems to be so much easier.
My favorite object in my office is a 3D-printed part for a home-built microscope (patent pending). 3D printing is used frequently in our instrument development.
My students and postdocs have given me many great moments at GSU. My favorite one is probably the moment I realized Fei Zhao (Ph.D. student) had finally beaten all odds to build a new microscope that I had been waiting for 4 years. The design was so challenging that a former postdoc and two former students (all great scientists) could not accomplish.
