Chairs:
Ning Dai & Yukako Komaki

Application Deadline

Applications for this meeting must be submitted by July 1, 2017. Please apply early, as some meetings become oversubscribed (full) before this deadline. If the meeting is oversubscribed, it will be stated here. Note: Applications for oversubscribed meetings will only be considered by the Conference Chair if more seats become available due to cancellations.

GRS Speaker Abstract Deadline: Although applications will be accepted until the date noted above, any applicants who wish to be considered for an oral presentation should submit their application by April 29, 2017. Please refer to the application instructions in the Meeting Description section below for more details (if available).

Meeting Description

Overview

The Gordon Research Seminar on Drinking Water Disinfection By-Products is a unique forum for graduate students, post-docs, and other early-career scientists to present new data, exchange cutting-edge ideas, and form an active research community in a casual setting.

The 2017 GRS technical session will focus on bringing together multidisciplinary research to address the balance of microbial and chemical safety of water. The topics will include, but are not limited to, mechanistic exploration of disinfection mechanisms and byproduct formation pathways, new analytical capabilities, high throughput toxicity evaluation, and assessment of public health outcomes. Such an holistic approach is critical for meeting the emerging challenges in wastewater recycling, desalination, and treatment of other alternative water sources. The 2017 GRS will also feature a mentoring session with panelists from the industry, academia, and utilities from the U.S. and abroad.

Application Instructions

The meeting will feature approximately 10 talks and 2 poster sessions. All attendees are expected to actively participate in the GRS either by giving an oral presentation or presenting a poster. Therefore, all applications must include an abstract.

The Chairs will select speakers from abstracts submitted by April 29, 2017. Those applicants who are not chosen for talks and those who apply after the deadline to be considered for an oral presentation will be expected to present a poster. In order to participate, you must submit an application by the date indicated in the Application Deadline section above.

Related Meeting

This GRS will be held in conjunction with the "Drinking Water Disinfection By-Products" Gordon Research Conference (GRC). Those interested in attending both meetings must submit an application for the GRC in addition to an application for the GRS. Refer to the associated GRC program page for more information.
