[Aspuru-Guzik group list] Wednesday of this week

by Edward Farhi

Dear Qanta We are going to meet tomorrow, that is, Wednesday at 3:00 in 6-310. We will meet again on Monday February 2 at 3:00 to organize for the term. The assumption is that we will continue to have the group meetings on Mondays at 3:00 so please let me know if there is a problem with that time. Note that on Monday Vidal is speaking at noon.

[Aspuru-Guzik group list] [iic-colloquium] IIC Colloquium Wed- Feb. 4 - Tamara Munzner- Visualization and Biology: Fertile Ground for Collaboration

by Pavlos Protopapas

Dear friends, The IIC Colloquium spring series begins next Wednesday. See http://iic.harvard.edu/events/upcoming for more details. If you would like to subscribe to our listserv for announcements of IIC colloquia and workshops, or if you would like to be removed from the list, please contact Helene Tingle Uysal, helene_tingle(a)harvard.edu. We hope you'll join us. Pavlos Protopapas Senior Scientist, IIC ******* Tamara Munzner, University of British Columbia IIC Colloquium - Visualization and Biology: Fertile Ground for Collaboration Date: Wednesday, February 4, 2009 Time: 4:00 p.m., refreshments at 3:30 p.m. Location: 60 Oxford Street, Room 330 Abstract This colloquium will focus on how visualization researchers and domain scientists can meet their goals through collaboration. Munzner will present two projects motivated by problems from biology, showing how visualization can dramatically speed up the workflow of scientific analysis. Cerebral, a system created in collaboration with immunologists, allows exploration of microarray data from multiple experiments in the context of biomolecular interaction networks. The Tree Juxtaposer system, created in collaboration with evolutionary biologists, supports visual comparison between large phylogenetic trees. _______________________________________________ iic-colloquium mailing list iic-colloquium(a)calists.harvard.edu http://calists.harvard.edu/mailman/listinfo/iic-colloquium

[Aspuru-Guzik group list] REMINDER: Excitonics Seminar - January 29

by rtavilla＠rle.mit.edu

TODAY Center for Excitonics Seminar Series Announcement The Center for Excitonics will be starting its seminar series in 2009 ( http://www.rle.mit.edu/excitonics). The Center is sponsoring a series of energy-related lectures from scholars and colleagues in the private sector who are working in the field. The first lecture is scheduled in January. We invite you to join us and to forward this information on to others who might be interested in attending this and other seminars. Title: Exploring Electron Transfer in Organic Semiconductors Presenter: Prof. Troy Van Voorhis Organization: Department of Chemistry, MIT Date: January 29, 2009 Time: 3:00 - 4:00pm Place: 36-428 Refreshments: Yes URL: http://www.rle.mit.edu/excitonics/vanvoorhis-012809.html Abstract Electron transfer reactions are the centerpiece of artificial photosynthetic complexes, organic LEDs and essentially all of redox chemistry. In particular, electron transfer rates govern the efficiency of exciton formation and dissociation in organic semiconductors. This talk will highlight ongoing work being carried out in our group aimed at accurately simulating the reaction dynamics in these systems. Specifically, we will focus on the electronic structure problem inherent in describing electron transfer: How do we make connections between a phenomenological picture like Marcus theory and more rigorous electronic structure techniques? How can we model the disorder inherent in organic solids? Bio Professor Van Voorhis graduated from University of California, Berkeley in 2001 with a PhD in Chemistry. After two years as a posdoctoral fellow at Harvard, he started as an Assistant Professor of Chemistry at MIT. He became an Associate Professor in 2008. Professor Van Voorhis' research focuses on the use of theory and modeling to understand the dynamics of electron motion in complex environments. His primary interests include the fundamental theory of electronic excited states, the description of electron transfer and the simulation of reactions that involve more than one electronic state. These processes are at the heart of several technological applications, including organic LEDs, artificial photosynthesis and molecular electronics. Professor Van Voorhis held the Paul M. Cook Career Development Chair in Chemistry, is a Sloan Fellow, a David and Lucille Packard Fellow and the recipient of a CAREER award from the National Science Foundation.

by Anna B. Shin

Dear Group, Just a reminder that Man Hong will be visiting this Friday. He will present his research at group meeting at 2pm in the Div Rm (the room is occupied until 2pm). We will finalize the Spring term group meeting time after our 4 undergrads finalize their class schedules which will be late next week. As of now, it looks like Thursdays at 2:30pm will work. *Graduate students*: please remember that Study Card Day is Wed 4 Feb. After that, the Registrar will charge a late fee. I can sign on behalf of Alan for his Chem 386 research course. If you have specific questions about classes, please see Carol and/or Alan. Thanks, Anna -- Anna B.
