CAUTION: The Sender of this email is not from within Dalhousie. We solicit proposals for contributed talks. We recommend preparing proposals of at most 2 pages, in either plain text or PDF format. However, we will accept longer proposals or submissions to other conferences, under the understanding that PC members are only expected to read the first two pages of such longer submissions. When submitting talk proposals, authors should specify how long a talk the speaker wishes to give. By default, contributed talks will be 30 minutes long, but proposals for shorter or longer talks will also be considered. Speakers may also submit supplementary material (e.g. a full paper, talk slides) if they desire, which PC members are free (but not expected) to read. We are interested in talks on all topics related to the interaction of higher-order programming and computational effects. Talks about work in progress are particularly encouraged. If you have any questions about the relevance of a particular topic, please contact the PC chairs, Filip Sieczkowski (efes@cs.uni.wroc.pl<mailto:efes@cs.uni.wroc.pl>) and Ohad Kammar (ohad.kammar@ed.ac.uk<mailto:ohad.kammar@ed.ac.uk>). ### Invited speaker Paul Blain Levy, University of Birmingham. ### Covid-19 Updates 1) Due to the Covid-19 pandemic, HOPE will take place online **only**. 2) After a hiatus of 1 year, we were hoping to use submission and participation data as surrogate measure for the community of, and the need for, the HOPE workshop. Since the Covid-19 situation may well skew those numbers, please do get in touch with the PC chairs with any input about the future of HOPE. ### Important Dates * Deadline for talk proposals: **May 18th, 2020** (Monday) [EXTENDED] * Notification of acceptance: **June 15th, 2020** (Monday) * Workshop: **August 23rd, 2020** (Sunday) ### Submission Link The submission website is now open: https://hope20.hotcrp.com/ Programme committee: Malgorzata Biernacka University of Wroclaw Raphaëlle Crubillé Paul Downen University of Oregon Francesco Gavazzo University of Bologna Sergey Goncharov FAU Erlangen-Nürnberg Jacques-Henri Jourdan Universersité Paris Saclay Ohad Kammar (co-chair) University of Edinburgh Daan Leijen Microsoft Research Agata Murawska University of Copenhagen Filip Sieczkowski (co-chair) University of Wrocław The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
