Klimley A. Peter Klimley, Ph.D.
Director, Biotelemetry Laboratory
Department of Wildlife, Fish, & Conservation Biology

Title: Conservation of Sharks: Humans beware of sharks? ...no sharks beware of humans!
Chapman University, Bush Conference Center, Beckman Hall 404
Noon to 1 p.m.

Synopsis: Dr. A. Peter Klimley has studied sharks for over four decades, topics ranging from the complex social habits and keen navigational abilities of hammerhead sharks to the feeding tactics and communication behavior of white sharks.  

Much of his recent focus has been on delineating the migratory pathways of sharks in order to help in specifying the extent of the boundaries of marine reserves at the Revilligigedos Islands off Mexico, Malpelo Island off Colombia, Cocos Island off Costa Rica, and the Galapagos Islands off of Ecuador.

He has appeared in close to three dozen film documentaries about the biology of sharks, and he is featured as "Dr. Hammerhead" on the Nova website. He has striven throughout his career to make the public aware of the fascinating behavior of this group of animals, and has been a strong advocate of shark ecotourism, which has become immensely popular recently among SCUBA divers.  He has to the contrary downplayed the risk of shark attack, explaining that it occurs less frequently than being struck by lightening.

Title: Looking inside quantum wave function collapse: what measurement can tell us about the arrow of time.

Chapman University, Bush Conference Center, Beckman Hall 404
Noon to 1 p.m.

Synopsis: This talk will describe recent experiments that reconcile the closed evolution of isolated quantum particles with the process of measurement, which reveal how quantum particles evolve from superpositions of states to definite states under measurement.
These experiments harness state of the art techniques to fabricate quantum circuits from superconducting metals and then to measure the quantum states of these circuits with extraordinary precision. By initializing the circuit in a superposition of two different energy states and then subsequently using weak measurements to slowly accumulate information about the state of the circuit, we are able to observe quantum trajectories of the state that continuously connect the initial superposition state to the final definite outcome.
These trajectories give us new ways to examine fundamental questions such the arrow of time and the origins of thermodynamics, as well as shed new light on everyday processes such as how lightbulbs emit light.

According to quantum mechanics, particles do not have definite properties such as position and momentum, but are instead described by a complex valued wavefunction. The wave nature of quantum particles means that these particles can exist in superpositions of seemingly disparate states, for example a quantum particle could be in two places at once, or heading in two different directions, or occupy a superposition of two different energy levels.
The evolution of this wavefunction obeys the Schrödinger equation which was formulated in 1925. Since it’s formulation, the Schrödinger equation has been applied to understand the properties of atoms and molecules and the basis for chemistry and materials. Yet, the Schrödinger equation only applies to isolated quantum systems.
If one is to measure the properties of a quantum particle with suitable precision, a definite answer may result even if the particle is in a superposition of states. Thus the act of measurement collapses the wavefunction from an initial superposition to a definite state. This collapse process cannot be described by the Schrödinger equation and reconciling the evolution of measured, “open” quantum systems with the theory has been a topic of intense debate and research since the origins of quantum theory.

Jeff Wilson, Director of Business Value Strategy & Development at Textile Exchange

Title: Pushing Sustainability Forward:  Business Collaborations and the State of the Art

Chapman University, Bush Conference Center, Beckman Hall 404
Noon to 1 p.m.

Dr. Michael S. Brown has worked in sustainability and environmental management for over 30 years leading efforts to establish cutting-edge programs and practices in industry and government. Clients in his consulting practice have included firms in apparel and footwear, personal care products, household products, and specialty chemical products along with public sector and nonprofit organizations.

Previously, he established and led Patagonia’s internal environmental sustainability program and developed innovative nonregulatory governmental programs that provided technical assistance on pollution prevention for large and small businesses.
Mike received his M.R.P. and Ph.D. degrees from the Department of City and Regional Planning, specializing in environmental health policy, at Cornell University.

He has written and spoken extensively on state-of-the-art sustainability practices and is co-author of the book, Workers at Risk and numerous journal articles. Dr. Brown serves as an Assistant Editor for the Journal of Industrial Ecology.

Jeff Wilson is the Director of Business Value Strategy & Development, responsible for ensuring meaningful business value is delivered to membership and their respective industry sectors. His role includes strategy development and implementation, membership value development and delivery, Supply Network platform development, the Learning Center, industry collaboration, and operations.

Jeff’s career has been in sales and marketing and general business management in the for-profit sector with numerous market leading companies including Delta Air Lines and Quiksilver/Roxy/DC Shoes. Jeff led the establishment of the global sustainability organization at Quiksilver and has been an active participant in industry collaboration with the Outdoor Industry Association Sustainability Working Group, the Sustainable Apparel Coalition, Cradle to Cradle, and the Organic Fiber Council.

Jeff has a Master’s in Business Administration in Marketing and Strategic Planning from the University of Southern California and a Bachelor’s degree in Environmental Studies from the University of California Santa Barbara.
