Dr. Christopher Langdon

I received my PhD in Biological Oceanography from the Graduate School of Oceanography at the University of Rhode Island in 1988.  My dissertation looked at the photo-physiological differences in three species of phytoplankton that explained why they bloomed at different times of the year.  During my time as graduate student I developed and patented an instrument for measuring dissolved oxygen in unstirred algal cultures that I used in my experiments. After, graduating from URI I accepted a post-doc position at Columbia University with Dr. John Marra. With him I worked on a Navy funded project looking at bioluminescence and the propagation of light through the water column.  During my years at Columbia I worked on many projects including measurements of open ocean primary production using the dissolved oxygen sensors I had developed as a grad student, a study of the effect of El Nino on primary production in the Indonesian Seas, hypoxia events along the New Jersey coast, the effect of Gulf Stream meanders on primary production off the US east coast, and a study of the effect of ocean acidification on corals conducted at the Biosphere 2 Center in Oracle, AZ. In 2005 I came to RSMAS at the University of Miami because I wanted to get involved graduate and undergraduate teaching and because RSMAS has long been a Mecca for coral reef research.  During my time at RSMAS I have supervised six PhD students and undertook research looking at the effects of ocean acidification on many aspects of coral biology and physiology including fertilization success, settlement, growth of juvenile and adult corals, heterotrophy, photosynthesis and respiration.  Currently I am supervising two PhD and two MS students.  I teach Introduction to Marine Biology Lab and Research Fundamentals to marine science undergrads and Tropical Marine Ecology and Field Techniques to RSMAS graduate students.

She is a distinguished professor at the University of Colorado Boulder, where she leads the Niwot Ridge Long-term Research Program, the Restoration Innovation Lab, and the Boulder Apple Tree Project. Katie studies the patterns and processes of life – species and how they interact, ecosystems and how they work – and how humans intersect with and affect these species and ecosystems. She is particularly interested in dynamics in systems over time, including feedback, resilience, and threshold effects, and how to manage and restore systems in a rapidly changing world. Katie received her PhD from the University of Michigan and spent a decade in the University of California system before joining the faculty at CU in 2014. She is a fellow of AAAS and the Ecological Society of America.

Dr. Virginia M. Weis

Virginia Weis is a Distinguished Professor of Integrative Biology at Oregon State University.  She obtained her PhD in 1990 in Biology from the University of California at Los Angeles in the area of coral reef biology and coral symbiosis.  She has been at OSU since 1996 where her group studies the cellular and molecular conversations that govern the relationship between corals and their microbial partners.  These symbioses are central to the health of coral reef ecosystems and when the partnerships breakdown due to environmental stress such as global warming, the entire reef ecosystem is threatened.  Her current focus includes efforts to build coral germplasm repositories to preserve coral biodiversity. She has instructed thousands of undergraduate students in introductory biology, invertebrate zoology, and the biology of symbiosis.  She has authored over 100 publications and mentored and trained 19 PhD students, 13 postdoctoral fellows and dozens of undergraduates.
