Opened Practices Users from Claremont

Char focuses on the intersection of education, research, technology, and design in library services.

Char focuses on the intersection of education, research, technology, and design in library services. She was E-Learning Librarian and liaison to the School of Information at UC Berkeley between 2008 and 2011, and recently joined the Claremont Colleges Library as Instruction Services Manager and E-Learning Librarian. Char completed a Master's of Educational Technology at Ohio University in 2008, a MSIS at the University of Texas at Austin's School of Information in 2005, and a B.A. in History at Reed College in Portland, Oregon in 2001.

710 N. College Ave.

Born in Mexico City, Mexico. BS in Mathematics from the Autonomous Metropolitan University. MS in Mathematics and Ph.D in Mathematics from Claremont Graduate University. Postdoctoral fellow at the Computational Molecular Biology and Bioinformatics of the University of Southern California 2003-2006.
Research Associate at the National Institute of Genomic Medicine 2006 to date. Adjunct Faculty at the School of Mathematical Sciences - Claremont Graduate University 2003- present. I taught for 3 years while I was a postdoctoral fellow at USC. Then from Mexico I have been teaching from outside the US as part of the distance learning initiative. Fall 2008 will be my 6th year teaching and the 3rd one online.
