Data Mining & Analytics; IT Economics; Internet Infrastructure & Operating Systems Network science is an emerging discipline focusing on the analysis and design of complex systems that can be modeled as networks. During the last decade or so network science has attracted physicists, mathematicians, biologists, neuroscientists, engineers, and of course computer scientists. I believe that this area has the potential to create major scientific breakthroughs, especially because it is highly interdisciplinary. We have applied network science methods to investigate the "hourglass effect" in developmental biology. The developmental hourglass' describes a pattern of increasing morphological divergence towards earlier and later embryonic development, separated by a period of significant conservation across distant species (the "phylotypic stage''). Recent studies have found evidence in support of the hourglass effect at the genomic level. For instance, the phylotypic stage expresses the oldest and most conserved transcriptomes. However, the regulatory mechanism that causes the hourglass pattern remains an open question. We have used an evolutionary model of regulatory gene interactions during development to identify the conditions under which the hourglass effect can emerge in a general setting. The model focuses on the hierarchical gene regulatory network that controls the developmental process, and on the evolution of a population under random perturbations in the structure of that network. The model predicts, under fairly general assumptions, the emergence of an hourglass pattern in the structure of a temporal representation of the underlying gene regulatory network. The evolutionary age of the corresponding genes also follows an hourglass pattern, with the oldest genes concentrated at the hourglass waist. The key behind the hourglass effect is that developmental regulators should have an increasingly specific function as development progresses. Analysis of developmental gene expression profiles from Drosophila melanogaster and Arabidopsis thaliana provide consistent results with our theoretical predictions. We are currently working on the inference and analysis of functional and brain networks. More information about this project will be posted soon.

Mustaque Ahamad, Ph.D., is the Associate Director of Education & Outreach for the Institute for Information Security & Privacy (IISP) and professor in the College of Computing at Georiga Tech. Within the IISP, he seeks to proactively address challenges associated with workforce development in cybersecurity. With oversight of formal degree programs and continuing education for working professionals, he is an advocate for greater cybersecurity education and training in order to meet the collective needs of industry and government. Ahamad's research interests are in the areas of converged communications security and security of healthcare systems. As smart-phone-like devices enable ubiquitous access to web and voice channels, the convergence of telephony with the Internet gives rise to new cross-channel threats that can combine online and voice attacks. For example, voice phishing with caller-ID spoofing has been reported for stealing online banking credentials. His data-driven research approach for exploring cross-channel threats has resulted in a better understanding of these threats and more effective ways to combat them. In the healthcare security area, he has worked on monitoring for detection of abuse and fraud. Ahamad co-founded Pindrop Security, which commercialized his group's research in the telephony security area, and he continues to serve as its chief scientist. He also serves as co-chair of the Messaging Malware Mobile Anti-Abuse Working Group (M3AAWG) special interest group on voice and telephony abuse. He also served as an external advisor for the Federal Trade Commission for telephony abuse. For nearly 20 years, he has been a leading figure in information security as an associate of the IISP's predecessor -- the Georgia Tech Information Security Center -- since 1998 and including serving as its director from 2004 to 2012. He earned his Master's and Doctoral degrees in Computer Science from the State University of New York, Stony Brook, and a B.E.
