Friday Demos for Dr. Beverly Harrison visit
by Seongkook Heo 04 Sep '18

04 Sep '18

Hi all, Dr. Beverly Harrison will be visiting this Friday (Sep 7). She is a principal researcher at Microsoft and has worked at many top research labs like Xerox PARC, Intel Research, Yahoo Research, and more. She has done really great work both in research and products (including Amazon Echo) and it'd be a great opportunity for us to meet. (check her website: http://www.beverlyharrison.org/) I know that everyone's busy with CHI projects, but again, it'll be a great chance for you to discuss your research with her, so please sign up for a demo. Demo slots are available between 2 pm and 4 pm. Send me an email if you'd like to do a demo. Best, Seongkook
