Andrew Farnsworth Visiting Scientist, Cornell Lab of Ornithology

Andrew Farnsworth is a Visiting Scientist in the Center for Avian Population Studies at the Cornell Lab of Ornithology. Andrew began birding at age 5 and quickly developed his long-standing fascinations with bird migration. His current research applies technology, including weather surveillance radar, audio and video recording and monitoring tools, citizen science datasets, and machine learning techniques, to study bird movements and their relationships to physical, biological, and anthropogenic environments. Andrew also speaks frequently to the media to promote understanding of this research and to educate more broadly on ways to support science and conservation of migratory birds. He received his BS in Natural Resources from Cornell, MS in Zoology from Clemson University, and PhD in Ecology and Evolutionary Biology from Cornell University. He has been involved with the BirdCast project since 1999, when as a graduate student in the Clemson University Radar Ornithology Lab under Dr. Sidney A. Gauthreaux he developed predictive models and analyzed forecasts and observations on the original website.

Adriaan Dokter Research Associate, Center for Avian Population Studies, Cornell Lab of Ornithology

Adriaan Dokter is a Research Associate at the Cornell lab of Ornithology. With a background in physics, his research bridges the disciplines of ecology, computer science, physics, and meteorology, addressing questions about the effects of global change on the distribution and seasonal migration of birds from continental-scale movements of species to fine-scale behavior of individuals flying through the atmosphere. Adriaan uses weather radar networks as well as individual tags to address questions in migration ecology, including when and where birds migrate, when and where birds die within the annual cycle, and how shifting patterns in mortality and recruitment of young birds cause bird abundances to change. He also develops software tools for biologists using weather radar as a tool in their research, including the R-package bioRad for biological analysis of weather radar data. After receiving a Ph.D. at the Institute of Atomic and Molecular Physics in Amsterdam, he studied animal movement during postdoctoral appointments at the Cornell Lab of Ornithology, the Netherlands Institute of Ecology, the University of Amsterdam, and the Netherlands Meteorological Institute.

Benjamin studied biology and statistics as an undergraduate at Cornell University and has been BirdCasting since 2012.

Julia Wang BirdCast Project Leader

Julia Wang is a project leader whose primary focus is on developing and coordinating Lights Out campaigns with conservation partners and local stakeholders to facilitate widespread public and governmental adoption of conservation practices. These campaigns integrate BirdCast research to better target which nights migratory birds are most at risk from the harmful effects of artificial night lighting, as well as to quantify intervention effect. Julia completed her B.A. in Government at Cornell University, and is particularly interested in the application of research to solving real world problems, and in behavioral change on both the individual and systemic level.

Dan Sheldon Assistant Professor, Department of Computer Science, University of Massachusetts, Amherst

Dan Sheldon’s primary research develops algorithms to understand and support decisions about the environment using large data sets. He and his colleagues and students are the primary machine learning research leads for BirdCast. He seeks to answer foundational questions and also to build applications that transform large-scale data resources into scientific knowledge and policy. Some examples of his work include spatial optimization to conserve endangered species, continent-scale modeling of bird migration, and biological interpretation of weather radar data across the US. Methodologically, Dan’s primary interests are machine learning, probabilistic inference, and network modeling. His work has contributed broadly applicable new approaches for reasoning about aggregate data in probabilistic graphical models, and for optimization of diffusion processes in networks.

Raphaël Nussbaumer Postdoctoral Fellow, Cornell Lab of Ornithology

Raphaël is a Postdoc fellow at the Cornell Lab of Ornithology. He is fascinated by the sheer number of birds migrating and their ability to navigate space and maintain perfect timing. He works on modelling and quantifying nocturnal bird migration using weather radar data. Drawing on geostatistical methods, he studies spatio-temporal patterns of bird migration, and, inspired by his background in Hydrology, explores ways to model mass bird migration as a fluid flow, quantifying nightly take-off and landing fluxes of take-off.

Carley Eschliman, BirdCast Alumna Editorial Assistant

Carley Eschliman was an editorial assistant at the Cornell Lab for the summer of 2018. She pursued majors in Atmospheric Science and Communication in the Cornell College of Agriculture and Life Science. Carley has been interested in weather since she first caught a glimpse of a tornado in her early childhood. She hopes that her studies at Cornell will equip her with skills to better bridge the communication gap between climate scientists and the general public. Through her work at the Cornell Lab, she wishes to encourage a closer partnership between birders and meteorologists, showing each group that there is a lot still left to learn about what is going on in the troposphere.
