Bella Karr Gerlich, PhDBella Karr Gerlich, PhD

Title: Professor and Dean
Employer: University of Alaska Fairbanks
Degree: PhD (Library and Information Science)
Graduation year: 2006

Bella Karr Gerlich is Professor and Dean of Libraries at the University of Alaska Fairbanks, a Land, Sea and Space Grant Institution. Gerlich has a BFA from Virginia Commonwealth University, a Master of Public Management from Carnegie Mellon University, and a PhD Library and Information Science from the University of Pittsburgh in 2006, where she taught management courses for the MLIS program. She draws experience from prior appointments as University Librarian at Dominican University, Associate University Librarian at Georgia College & State University, and Head, Arts & Special Collections at Carnegie Mellon University. Gerlich oversees all aspects of the Libraries’ academic and administrative programs and services, is an advisor to the UAF rural campuses, and fosters state, national, and international partnerships for the Libraries.

Gerlich is active in the profession, serving in committee and leadership positions at the local, state, and national levels. Gerlich is an engaged researcher; her interests include assessment, organizational behavior, and valuation of services; she has authored / co-authored a number of peer-reviewed publications, is a frequent guest lecturer, presents at professional venues both in the U.S. and abroad and enjoys mentoring students.

As both administrator and researcher, Gerlich has worked to identify, quantify, and acknowledge the hidden work done by library staff through the development of a qualitative data-gathering methodology that can be normalized across institutions. Inspired by her dissertation research at SIS (Work in Motion / Assessment at Rest: An Attitudinal Study of Academic Reference Librarians), Gerlich created the READ Scale (Reference Effort Assessment Data – http://readscale.org), a 1 – 6 scale for recording the effort, knowledge, skill, and teaching that occur during reference transactions. More than 100 libraries worldwide have self-identified their use of the tool, which has been incorporated as a free option in both Springshare (LibAnalytics) and Compendium LLC (Desk Tracker) data analysis products. The Scale will be included in the upcoming book ‘Implementing and Inclusive Staffing Model for 21st Century Reference Services: A Practical Guide’ by Julia Nims, and an article co-authored with G. Lynn Berard “Testing the Viability of the READ Scale: Qualitative Statistics for Academic Reference Services” was selected for inclusion in the Reference Research Review for 2010, an annual bibliography that focuses on annotating items of importance to the practice of reference. The READ Scale was featured on the Medical Library Association website and has been the subject of numerous presentations by professionals in the field. In addition to ongoing promotion of the READ Scale, Gerlich’s current research agenda includes collaboration with other libraries to test her LEAD Scale (Library Effort Assessment Data) that evolves the 1 – 6 scale tool beyond reference transactions to record qualitative data across all library work functions.

Maria Harrington, PhDMaria Harrington, PhD

Title: Founder and CEO
Employer: Virtual Field Trips, LLC
Degree: MSIS, PhD (Information Science)
Graduation Year: 1990, 2008

Maria Harrington (MSIS ’90, PhD ’08) was featured in the spring 2015 issue of Shady Ave Magazine for her dissertation research. Dr. Harrington’s dissertation, defended and published in 2008, “Simulated Ecological Environments for Education (SEEE): A Tripartite Model Framework of HCI Design Parameters for Situational Learning in Virtual Environments,” investigated the empirical inter-relationships between humans, computers, and the environment.

Harrington states, “The contribution of my dissertation provided a new approach to the question of learning in virtual reality, not from the long-standing educational pedagogy or philosophical paradigm of “immersion” or “presence,” nor the new “gamification” approach of serious games. Instead, I focused on the design factors in the system, isolated those factors, measured their impact, and reported the results. I adopted a human-computer environment interaction and a human information processing view, rather than “educational systems to meet the opportunities and challenges of the 21st century” perspective, and showed that the historical focus on the “educational outcomes and standards” left relevant human-computer interaction and system design factors understudied. This approach brings the focus of students’ needs, teachers’ abilities, knowledge stores, context/environment, and the factors of the computer system, such as visual fidelity and navigational freedom, back into the analysis, opening a new direction for an empirical study of the child learning in context, real and virtual.” Read more about her research.

Her new research direction is in the investigation of designing, building, and deploying environments where creative engagement is not just possible, but becomes more likely, especially for the child. As also a CMU-trained artist, she knows this is possible as she creates her own new media art. Read more about The Virtual Trillium Trail.

Saman Taghavi Zargar, PhDSaman Taghavi Zargar, PhD

Title: Software Engineer (III)
Employer: Cisco Systems
Degree: PhD (Telecommunications)
Graduation year: 2014
Saman Taghavi Zargar, PhD has been a Software Engineer (III) at Cisco Systems since August 2014. Saman is part of the Security Business Group (SBG) where he is involved in proposing secure architectures for various Cisco products and for the next generation of Internet infrastructure, a topic that has always been of interest to him. Sam chose the iSchool for his doctoral studies “because of its unique Telecommunications and Networking program and the faculty’s research interests on network security.”
Sam’s advice for current students is to complete an internship because it can teach you “where to better utilize your skill-set and how to find the satisfaction that everyone seeks in his/her job.” For students who find themselves on the job market, Sam recommends “networking with recruiters and hiring managers through LinkedIn and at academic conferences.” Additionally, recent graduates should leverage their internship experiences to obtain competitive offers and to negotiate the terms of an offer, something that many fresh grads leaving academia for industry find challenging.
Sam defended his dissertation, “Towards Coordinated, Network-wide Traffic Monitoring for Early Detection of DDoS Flooding Attacks” in June 2014. While a student at the iSchool, Sam received a Cisco Research Award for his proposal “DiCoTraM: Towards a Distributed Collaborative Traffic Monitoring System” in the amount of $54,000 (August 2012-2013) and the Fritz Froehlich Award for outstanding contributions to the graduate program in Telecommunications (April 2011). Additionally, his paper “A Survey of Defense Mechanisms against Distributed Denial of Service (DDoS) Flooding Attacks” (Impact Factor: 4.818) was listed among the Top Ten most popular articles published in IEEE Communications Society periodicals for eight months since it first appeared online (July-December 2013, January, February, April 2014). More of Sam’s research can be found on Google Scholar.
