  Speaker: Liangbing Hu, Department of Materials Science and Engineering, Stanford University
  
  Talk Title: Nanostructured Energy Devices: Manipulating Electrons, Photons and Ions
  
  Abstract: Lowering the cost and improving the performance of devices are essential for making renewable energy feasible for everyday applications. In this talk, I will focus on discussing how abundant materials such as paper, silicon and copper can be engineered to create one dimensional nanomaterial networks (Nano-Nets) which allow us to manipulate fundamental particles in these energy devices to ultimately obtain remarkable performance. Conductive Nano-Nets using carbon nanotubes, silver nanowires and copper nanofibers for transparent electrodes in solar cells, silicon Nano-Nets for high performance Li-ion battery anodes, and conductive paper and textiles for ultracapacitors and microbial fuel cells will be discussed in detail.
  
  Biography: Liangbing Hu received his B.S. in applied physics from the University of Science and Technology of China (USTC) in 2002. He did his Ph.D. in experimental physics under Prof. George Gruner at UCLA, focusing on carbon nanotube based nanoelectronics. He studied extensively the charge transport in carbon nanotube thin films with randomly distributed energy barriers and its dependence on geometry (nanotube length, density et al.) and energy (frequency, temperature and field). He also explored the device applications of such random networks in field effect transistors, sensors and optoelectronic devices. In 2006, he joined Unidym as a co-founding scientist. At Unidym, Liangbing’s role was the development of roll-to-roll printed carbon nanotube transparent electrodes and device integrations into touch screens, LCDs, flexible OLEDs and solar cells. Currently, Liangbing is a postdoctoral research fellow at Stanford University in Prof. Yi Cui’s lab where he is working on various energy devices based on nanomaterials and nanostructures including Li-ion batteries, ultracapacitors and microbial fuel cells. He has ~ 50 journal publications in nanomaterials, nanoelectronics, printed electronics and energy devices.

  Speaker: Chris Welty, Research staff member, IBM Watson Research Center
  
  Talk Title: Inside the mind of Watson
  
  Abstract: Watson is a computer system capable of answering rich natural language questions and estimating its confidence in those answers at a level of the best humans at the task. On Feb 14-16, in an historic event, Watson triumphed over the best Jeopardy! players of all time. In this talk Chris Welty will discuss how Watson works and dive into some of its answers (right and wrong).
  
  
  
  Biography: Biography: Chris Welty is a Research Scientist at the IBM T.J. Watson Research Center in New York. Previously, he taught Computer Science at Vassar College, taught at and received his Ph.D. from Rensselaer Polytechnice Institute, and accumulated over 14 years of teaching experience before moving to industrial research. Chris' principal area of research is Knowledge Representation, specifically ontologies and the semantic web, and he spends most of his time applying this technology to Natural Language Question Answering as a member of the DeepQA/Watson team and, in the past, Software Engineering. Dr. Welty is a co-chair of the W3C Rules Interchange Format Working Group (RIF), serves on the steering committee of the Formal Ontology in Information Systems Conferences, is president of KR.ORG, on the editorial boards of AI Magazine, The Journal of Applied Ontology, and The Journal of Web Semantics, and was an editor in the W3C Web Ontology Working Group. While on sabbatical in 2000, he co-developed the OntoClean methodology with Nicola Guarino. Chris Welty's work on ontologies and ontology methodology has appeared in CACM, and numerous other publications. see:
