Colloquium Series

Once every week while school is in session, EECS invites a distinguished researcher or practitioner in a computer science or electrical and computer engineering-related field to present their ideas and/or work. Talks are generally targeted to electrical engineering and computer science graduate students. This colloquium series is free and open to everyone.

Upcoming Colloquia

Supporting Software Development Work

Monday, October 20, 2014 - 4:00pm to 4:50pm
KEC 1003
Speaker Information
Thomas LaToza
Postdoctoral Research Associate
University of California, Irvine

Software development is a complex and multifaceted endeavor, encompassing diverse activities including programming, design, and collaboration interwoven together. While it is often not difficult to posit opportunities for tools to make development work better, understanding if and how tools lead to improvements in developers' lives and the software that they produce poses deeper questions about the nature of software development work itself and the relationship of this work to the tools that developers use to do it.

Topological Effects in Nanomagnetism: From Perpendicular Recording to Monopoles

Monday, October 20, 2014 - 1:00pm to 2:00pm
WNGR 275
Speaker Information
Hans-Benjamin Braun
School of Physics
University College Dublin, Ireland

Similar to knots in a rope, the magnetization in a material can form particularly robust configurations. Such topologically stable structures include domain walls, vortices and skyrmions which are not just attractive candidates for future data storage applications but are also of fundamental importance to current memory technology. For example, the creation of domain wall pairs of opposite chirality delimits the thermal stability of bits in present high anisotropy perpendicular recording media.

Speaker Biography: 

Hans-Benjamin Braun is currently Associate Professor for Theoretical Physics at University College Dublin (Ireland). After studies in Physics and Mathematics he received his diploma degree from the Unversity of Basel (Switzerland) and in 1991 he earned his PhD in Theoretical Physics at ETH in Zurich. After postdoctoral research at the Physics Department and the Center for Magnetic Recording Research at the University of California at San Diego he was awarded a NSERC International Fellowship to work at Simon Fraser University in Vancouver (Canada). Subsequently he returned to Switzerland to take up a position as Senior Scientist at the Paul Scherrer Institute (PSI). He joined the Faculty of the School of Physics at University College Dublin (UCD) in 2004, where he founded and leads the group in Condensed Matter Theory supported by the Science Foundation of Ireland. Prof. Braun developed the theory for nonuniform thermally activated magnetization reversal in nanowires which now forms the basis for the design of perpendicular magnetic recording media. Well before it was recognized experimentally, he theoretically predicted quasi one-dimensional behavior in magnetic nanowires and he introduced the now widely used notion of domain wall chirality. His work led to the prediction of the spontaneous emergence of spin currents in quantum spin chains, an effect that he and his collaborators subsequently observed via spin polarized neutron scattering. Furthermore he proposed and interpreted a series of experiments on nanolithographic arrays that led to the discovery of emergent monopoles in artificial spin ice together with colleagues from PSI and UCD. In addition to numerous publications in top research journals he also authored popular articles for the French and German versions of Scientific American and he holds two patents.

Towards Modular Computer Language Components

Monday, October 27, 2014 - 4:00pm to 4:50pm
KEC 1003
Speaker Information
Tillman Rendel
Research Associate
University of Tübingen

A modern software project uses many computer languages for source code, configuration files, database queries, scripts, network protocols, user-interface specifications, API descriptions, and so on. Some of these languages are developed by dedicated language designers for a wide audience, but others are defined for use in a single project or for the projects of a single company.

Speaker Biography: 

Tillmann Rendel works on solving software engineering problems through programming language methods. His research interests include domain-specific languages, extensible languages, modular software development in functional and object-oriented settings, and software product lines. Tillmann studied at the Technical University of Darmstadt, Germany, the University of Aarhus, Denmark, and the University of Marburg, Germany. He is now a research associate at the University of Tübingen, Germany.

Characteristics of (1+1)D Optical Waves

Monday, November 3, 2014 - 4:00pm to 4:50pm
KEC 1003
Speaker Information
Kyoung-Youm Kim
Associate Professor
Department of Optical Engineering
Sejong University

In this talk, I will discuss the characteristics of two types of (1+1)D optical waves. The first one is so-called Airy beams which can propagate in free space without any diffraction. In addition, they are accelerated or self-bend during propagation. Using these features, I suggest schemes for particle manipulation and slow/superluminal light transmission. Next, surface waves are considered. They are usually guided through interfaces between different media.
