Evangeline Ballerini Ballerini Lab

Evangeline Ballerini is an Assistant Professor in Biological Sciences at California State University, Sacramento. Evangeline’s research examines the evolutionary genetics and developmental biology of traits influencing ecological interactions between plants and pollinators with a focus on the genus Aquilegia. Evangeline earned a BA from the Integrative Biology department at the University of California, Berkeley and a PhD from the Organismic and Evolutionary Biology department at Harvard University and conducted postdoctoral research at the University of Georgia and the University of California, Santa Barbara.

Abstract: The genus Aquilegia, commonly known as columbine, represents a classic example of adaptive radiation following the evolution of a key innovation - floral nectar spurs. Nectar spurs, tubular outgrowths of floral tissue that produce and store nectar, are hypothesized to promote speciation through pollinator specialization. Variation in spur morphology, along with other floral features such as color and orientation, allows flowers to adapt to different animal pollinators, contributing to reproductive isolation. I will present work focused on understanding the genetic basis of trait evolution in the genus Aquilegia at multiple evolutionary timescales. To shed light on how nectar spurs evolved in the Aquilegia ancestral lineage, I will highlight studies in which I used a combination of genomic and transcriptomic analyses to identify a key gene regulating nectar spur development. Focusing on more recent evolutionary history, I will discuss work in which I use similar techniques to explore the genetic basis of several floral traits distinguishing closely related Aquilegia species adapted to different animal pollinators and examine the population genetic processes influencing the evolution of these traits important for ecological speciation in the genus.

 Erin Heath

Erin Heath is the Director of Federal Relations at the American Association for the Advancement of Science, the world’s largest general scientific society and publisher of the journal Science. The Office of Government Relations provides timely, objective information on science and technology issues to lawmakers, and it assists scientists in understanding and getting involved in the policy process.

Erin leads the federal policy team at AAAS and is heavily involved in efforts to empower scientists and engineers to engage with policymakers, the media and the public. She co-chairs the Coalition for National Science Funding, the Engaging Scientists and Engineers in Policy Coalition, and the steering committee of the Golden Goose Award. She played a key role in the launch of the Center for Scientific Evidence in Public Issues (EPI Center) at AAAS and serves on its internal advisory committee. She is also the inaugural chair of the Governing Board of the Journal of Science Policy and Governance.

Before joining AAAS, Erin worked for the American Institute of Biological Sciences, where she led the organization’s media training and outreach efforts and cut her teeth on science policy. Erin holds a Master of Science with Merit in Public Policy and Administration from the London School of Economics and Political Science. While in London, she served as a research assistant in Parliament. Prior to graduate school, she spent years as a journalist in Washington, most notably as a science policy reporter and columnist for the National Journal. She earned a B.A. in Journalism from the University of Maryland.

In 2017, Erin was awarded the AAAS Champion Award, given to an individual who has "championed" the mission of AAAS with a positive attitude and has inspired and motivated others to embrace and fulfill the AAAS vision.

Dr. Michael Long

Michael Long is the Thomas and Susanne Murphy Professor of Neuroscience at the NYU School of Medicine. He completed his graduate studies with Barry Connors at Brown University where he investigated the role of electrical synapses in the mammalian brain. During his postdoctoral work with Michale Fee at MIT, Long began to study the songbird model system to uncover the cellular and network properties that give rise to learned vocal sequences. Since beginning his laboratory in 2010, Long has focused his attention on the neural circuits underlying skilled movements, often in the service of vocal interactions. To accomplish this, the Long lab has taken a comparative approach, examining relevant mechanisms in the songbird, a newly characterized neotropical rodent, and humans. In addition to federal funding, the Long lab has also received support from NYSCF, the Rita Allen Foundation, the Klingenstein Foundation, and the Herschel-Weill Foundation.

Abstract:  Vocal communication is central to our everyday lives, facilitating social exchange. Despite significant recent discoveries, the neural mechanisms underlying coordinated vocal exchanges remain poorly understood. We examine the brain processes involved in interactive vocal behaviors, focusing on forebrain circuitry in the songbird and the rodent, and we relate these to emerging human studies that employ a range of methods to manipulate and monitor cortical areas relevant for speech.
