Crossroads in Science

The American Phytopathologoical Society

Welcome

to the 2015 APS Annual Meeting

On behalf of The American Phytopathological Society, I’m pleased to welcome you to Pasadena for the 2015 Annual Meeting. The theme of this year’s annual meeting, “Crossroads in Science”, reflects the unique position our discipline holds within the broad field of plant sciences. Our meeting will offer the latest advances, innovations, and discoveries as we explore new ways to connect with the worldwide community of scientists. Our Plenary Sessions will offer a dynamic look into the future of our science, and we will have fun examining generational perspectives among our membership. Our scientific program will include special sessions, workshops, technical sessions, and educational opportunities including field trips and workshops. As always, we encourage you to take full advantage of the many social gatherings and networking events to renew old friendships, establish new relationships, and meet the next generation of plant pathologists. Welcome to the 2015 APS Annual Meeting. We’re glad to see you in Pasadena! Rick Bennett, APS President

We are coming together this week to share the latest science in the plant pathology community and to explore great work in interconnected disciplines. I am excited about the opportunities to learn, share, and network through posters, technical and special sessions, plenary sessions, and plenty of social events. Students, don’t be shy and join in the mix, introduce yourselves to fellow scientists and educators, join a committee, contribute to Idea Cafés, or join the discussion around a Poster Huddle. The meeting app will help us all stay organized and remember all of our “must do” events. Let’s all have a great meeting in the beautiful “City of Roses!” Sally Miller, APS Program Chair and President-Elect

U.S. Food Waste Challenge On June 4, 2013, the U.S. Department of Agriculture (USDA), in collaboration with the U.S. Environmental Protection Agency (EPA) launched the U.S. Food Waste Challenge, calling on others across the food chain—including producer groups, processors, manufacturers, retailers, communities, and other government agencies-to join the effort to reduce, recover, and recycle food waste. APS supports this effort by working with the hotels and convention centers to donate food from APS meetings to food shelves in the local area.

Do not travel alone—stay in groups and travel in well-lit areas. Remove name badges when outside the hotel or Convention Center unless you are participating in a meeting event. • Do not give your room number out to anyone you do not know and avoid giving out your room number in conversations where strangers may hear you talking. • Bolt your hotel room door and only open it when you know who is on the other side. (Note: Hotel personnel wear uniforms and have identification badges. If in doubt, call hotel security to verify an employee’s identity.) • Do not leave your door ajar if you are going down the hall for ice. Someone may enter when you are not looking. • Know where the stairs are located in case of a fire (do not use elevators). Also count the number of doors to the nearest exit in case you cannot see in a smoke-filled hallway. • Valuables, airline tickets, and money should be kept in a hotel safety deposit box or in a room safe, if available.

• Try to leave the hotel as quickly as possible. If you cannot, stay in your room and call the operator or security to let them know you are in your room. • Put your hand on the room door to see if it is hot before opening it. If it is, do not open it quickly. Open it just a crack to see what is on the other side and be prepared to slam it shut quickly if necessary. • If you leave the room, take your room key with you! Shut your room door to keep smoke out. You may have to return if the exit is blocked. Remember the way back to your room as you go to the exit in case you need to return. • If necessary, drop to your knees to avoid smoke. Tie a wet towel around your nose and mouth to act as a smoke filter. Fold it into a triangle and put the corner in your mouth. • Do not take the elevator when you smell smoke or if you know that there is a fire in the building.

PLENARY SESSION I

Doug Parker– Ph.D., Director, California Institute for Water Resources, University of California, Agriculture and Natural Resources, Oakland, California, U.S.A. California is now into its fourth year of record-breaking drought. Water restrictions and a call for mandatory reductions have impacted all users of water in California. These historic conditions have everyone looking for a silver bullet solution to California’s drought. The fact is that in this large and semi-arid state, water is intimately tied to every aspect of life. To understand California’s water situation, one must recognize a fundamental paradox: Enough will never be enough. We are a land-rich but water-limited state, and increased supply leads to more demand, which makes answers to California’s water challenges complex, involving a combination of policy, technology, and conservation.

Crossroads in Science

Michael Rogers – Author, Technology Pioneer, and Futurist The 21st century has brought enormous opportunities to the life sciences: big data, cognitive computing, and increasingly inexpensive tools for genomics. But the challenges have grown also, from the needs and impacts of a still-rising world population to the decrease in public funding for research and development. Add to that a generalized public mistrust of any work that involves “genetic engineering,” and you have a complex environment indeed. What kind of careers lay ahead for young scientists, with the rise of peer-topeer innovations like crowdfunding and open access journals? How do older researchers adapt to disciplines that seem increasingly driven by algorithms? And what is the responsibility of scientists to speak out on global issues that may well threaten life as we know it? Find answers to

Guests’ tickets are available for purchase at the Registration Desk.

Four distinct generations are working together shoulder to shoulder, each with a unique set of attitudes, values, and work styles. It used to be that older workers were bosses and younger ones took orders. Now, roles are all over the map and rules are being rewritten. Businesses and institutions are feeling the pain of generations and they struggle to manage productivity and morale while maintaining high standards and morale. This program will give you the tools to convert this form of diversity from an obstacle to an opportunity.
