Samuel H. Moseley Maniac Lecture

January 24

Dr. Samuel H. Moseley, Senior Astrophysicist at GSFC, presented a Maniac lecture entitled, "HIRMES - Probing the Inner Secrets of Protoplanetary Systems - and that's not all!" Over the last three years, Harvey and team have been developing the HIRMES (High Resolution Mid-Infrared Spectrometer) instrument to probe the inner secrets of protoplanetary disk, where the solids materials, on a very short time scale, are separated from the gas to allow the coalescence of planets. In this lecture, he talked about how they have designed this cool (cold?) instrument that enables the exploration of the formation of planetary systems such as our own solar system. Harvey described the science program, instrument design, and provided a status report on HIRMES. They plan to be ready for the first commissioning flights in spring of 2019, so it is not too early to explore the possibilities that HIRMES will enable. And more importantly, Harvey talked about his own journey and shared some wisdom gathered over the years, especially with colleagues who are just starting out.


Dr. Samuel H. Mosely is a senior astrophysicist at NASA's Goddard Space Flight Center. Moseley’s accomplishments include the inventions of superconducting imaging arrays for astronomy, ranging from sub-millimeter bolometers to energy sensitive X-ray microcalorimeters, and even dark matter detectors, as well as microshutter arrays for the James Webb Space Telescope near-infrared spectrometer, which promise to enable detailed study of the first galaxies to form in the universe after the big bang. Before the Webb, Moseley worked extensively on COBE as a member of its Science Working Group. The satellite made groundbreaking measurements of the Cosmic Microwave Background Radiation, which show the universe soon after the big bang. Astrophysicists John Mather and George Smoot won the 2006 Nobel Prize in physics for this work. He has also worked on the many programs that have either flown or are expected to fly: the Kuiper Airborne Observatory, the Stratospheric Observatory for Infrared Astronomy (SOFIA), NASA’s Spitzer Space Telescope and Japan’s Suzaku (ASTRO-E2) mission. Moseley received his bachelor’s degree from Connecticut College, his master’s degree and doctorate from University of Chicago. He is a member of the American Physical Society and the American Astronomical Society.

Elizabeth M. Middleton Maniac Lecture

March 28

Dr. Elizabeth M. Middleton, a senior terrestrial ecosystem and carbon cycle scientist at GSFC, presented a Maniac lecture entitled, "Four Satellites and a Cornfield." In this lecture, Betsy talks about her unconventional path as a woman scientist while balancing family and care-giver responsibilities. She recently claimed her 40 year NASA Certificate and Pin. During those four decades she has been fortunate to be directly involved in four satellite missions. These were Landsat (ERRSAC), EO-1 (Mission Scientist), an ESA mission (FLEX) now in formulation phase A, and a successful NASA mission concept development team (HyspIRI). In addition, she has been involved in basic research on plant physiology and reflectance characteristics. Various in situ studies include hyperspectral and BRDF properties of plant canopies, UV-B effects on soybean, and nitrogen and drought effects on photosynthesis and fluorescence in cornfields. She was also a PI and Co-PI in the FIFE and BOREAS multi-year field campaigns.


Dr. Elizabeth M. Middleton is a senior terrestrial ecosystem and carbon cycle scientist at NASA Goddard Space Flight Center, focusing on the photobiology and remote sensing of vegetation, with expertise in field and laboratory measurements of plant physiological and spectral optical properties, project management, and satellite remote sensing of ecosystems. She leads a research team that studies vegetation spectral bioindicators of plant stress and photosynthetic function, including plant fluorescence. Over the last four decades with NASA, she has been directly involved in four satellite missions including Landsat (ERRSAC), Earth Observing One (EO-1, Mission Scientist for 9 years), formulation of an ESA mission (FLEX - the FLuorescence EXplorer, as the NASA representative for 10 years), and a successful NASA mission concept development team (HyspIRI - Hyperspectral Infrared Imager, 10 years as the GSFC leader), which was recently selected for development towards formulation by NASA. She was a Co-I in the tall grass prairie campaign as part of the FIFE (First ISLSCP) Field Experiment in Kansas (mid 1980s), a PI in the boreal forest studies in Saskatchewan during the BOREAS (Boreal Ecosystem Study) campaign (mid 1990s), the data system manager for the GSFC team for the Large Scale Ecosystem Study in Amazonia (LBA) in Brazil (late 1990s), and the research leader for the Fluorescence Laboratory, jointly conducted with USDA/Beltsville, MD. The fluorescence research has included a two-decade summer research campaign largely conducted at the local USDA research cornfield. In addition, she was a member of the NASA/GSFC Carbon Cycle Science Working Group (2000–2007) and the NASA representative to the U.S. Federal Geographic Data Committee's Vegetation Subcommittee for many years. Dr. Middleton won the 2012 Nordberg Award and has won other numerous NASA career achievement awards. She received the B.S. degree in Zoology, the M.S. degree in Ecology, and the Ph.D. degree in Botany (plant physiology) from the University of Maryland, College Park, in 1967, 1976, and 1993, respectively. She joined NASA in 1978.

Gavin A. Schmidt Maniac Lecture

April 18

Dr. Gavin A. Schmidt, Director of the NASA Goddard Institute for Space Studies in New York, presented a Maniac lecture entitled, “Contingencies, Communications, and Climate.” When he was much younger, Gavin assumed that progress in a career (or indeed, life), was a smooth, incremental climb to success. Looking back, he sees instead the chasms, the asteroids, and a series of seemingly trivial decisions that ended up having the biggest consequences. Nonetheless, there are things that he picked up along the way that have molded the kind of science he does, and the approach he takes to being a (semi-accidental) public scientist in the contested subject of climate change.


Gavin Schmidt graduated from Oxford University with a BA (Hons) in mathematics in 1988 and a PhD in applied mathematics from the University College London in 1994. From 1994-1996, Dr. Schmidt worked at McGill University as a postdoc; 1996-1998, NOAA Climate and Global Change fellow at NASA Goddard Institute for Space Studies (GISS) in New York; 1998-2004, Associate Research Scientist at Columbia University. He joined NASA GISS in 2004 and became Director of GISS in 2014.

His main research interest is in climate variability, which can be both internal and externally-driven. He uses and helps develop coupled ocean-atmosphere climate models, including GISS ModelE. One of his specific interests is using "isotopically enabled" models that track oxygen-18 and deuterium tracers in water throughout the climate system, allowing the model to simulate the pattern of isotopes observed in satellite retrievals, ice cores, cave records and ocean sediments.

Dr. Schmidt has often appeared in the media to discuss climate-related stories, current events or give lectures. He has worked with (among others) the American Museum of Natural History, the Smithsonian, the College de France, and the New York Academy of Sciences for education and outreach. Dr. Schmidt helped co-found the RealClimate blog in 2004 and published a book “Climate Change: Picturing the Science” with co-author Joshua Wolfe in 2009. In October 2011, the American Geophysical Union awarded Schmidt the inaugural Climate Communications Prize, for his work on communicating climate-change issues to the public.

Dennis J. Andrucyk Maniac Lecture

May 23

Dennis J. Andrucyk, Deputy Associate Administrator, Science Mission Directorate, NASA Headquarters, presented a Maniac lecture entitled, "Speak Your Mind, but Ride a Fast Horse; From GS-1 to SES. How in the world did that happen?" As kids, many of us think about what we “want to be” when we “grow up”… but that didn’t really happen for Dennis … it would have been impossible to plan his career the way it played out… change was a constant… in the end, and fortunately, he wouldn’t want to change a thing (okay… well… maybe a couple of things). Dennis shared a few career strategies, how he misread a couple of things along the way, applying for jobs (particularly SES), and the “art” of saying yes to new opportunities.


Dennis Andrucyk became the Deputy Associate Administrator for NASA's Science Mission Directorate (SMD) in 2017. From 2015-2017, he served as NASA’s acting chief technologist and as deputy associate administrator for the Space Technology Mission Directorate (STMD). From 2003-2015, Andrucyk held many senior executive positions at NASA’s Goddard Space Flight Center, including Director of the Applied Engineering & Technology Directorate, Chief of the Software Engineering Division, and Chief of the Mission Engineering and Systems Analysis Division.

Robert W. Corell Maniac Lecture

November 13

Dr. Robert W. Corell, Chair, Arctic Climate Impact Assessment & Principal, Global Envi-ronment and Technology Foundation, presented a Maniac lecture entitled, “Science Goes Global.” This Maniac Talk is about “Science Goes Global,” a quest for centuries that began with Pythagoras, the Greek philosopher, alluding to a “Spherical Earth.” Humankind ever since has sought to understand and exploit an understanding of a global Earth. This talk is designed to tell personal stories, examples of extraordinary scientific leadership, actions often unexpected in government programs and unparalleled personal dedication that have occurred over the past 50 years. It is argued that science going global has substantially enhanced scientific understanding and projections of natural and human-caused changes in the Earth’s environment on time scales of hours to years and beyond.


Dr. Robert W. Corell is an Adjunct Professorship at the University of Miami’s Department of Ocean Sciences and holds a professorship at the University of the Arctic. The is a Principal at the Global Environment Technology Foundation where he leads its Center for Energy and Climate Solutions.

He is a Senior Fellow at the the Consortium for Ocean Leadership. He was a Council Member of the Global Energy Assessment (GEA) and lead author of GEA’s Chapter 3 on Environment and Energy. He led the Arctic Climate Impact Assessment (2005) and most recently lead a comprehensive study of governance issues in the circumpolar Arctic. In 2013, chaired and was the lead author of the 2013 UNEP Year Book on “The View from the Top Searching for Responses to a Rapidly Changing Arctic” and more recently, the Co-Chair of the 2016 UNEP’s GEO-6 North American Regional Assessment. He was recognized with the other scientists for the 2007 Nobel Peace Prize for his work with the International Panel on Climate Change (IPCC) assessments. In 2008 he was awarded an Honorary Doctor of Science, University of Alaska, Anchorage and in 2010, he was awarded an Honorary Doctor of Veterinarian Medicine by the Norges Veterinærhøgskole (Norwegian School of Veterinarian Science). In 2017, Case Western Reserve University Case Alumni Association awarded him the Gold Medal Award for lifetime achievements. A circular mountain region forming the head of a glacier in Antarctica was named in 2003 the “Corell Cirque” by the Board on Geographical Names (79°54′00″S, 155°57′00″E).

Dr. Corell is actively engaged in research concerned with the sciences of global change and the interface between science and public policy, particularly research activities that are focused on the science of global and regional climate change. This effort is designed to facilitate understanding of vulnerability and sustainable development. For example, he is a lead author in the 2011, 2016 and 2017 North Pacific Arctic Conference’s Annual book, the last of which is titled: A North Pacific Dialogue on Building Capacity for a Sustainable Arctic in a Changing Global Order. He has published several dozen peer-reviewed articles and book chapters during the past decade, a recent example is 2016 GEO-6 Global Environment Outlook: Regional Assessment for North America, UN Environment Programme and 2017 Chapter 6 Impact analysis and consequences of change. Adaptation Actions for Changing Arctic (AACA), Arctic Council and AMAP and the section author of the book, “2052 - A Global Forecast for the Next Forty Years” by Jorgen Randers, that provides mid-century global climate projections. He is a Science Advisor to the National Geographic “Years of Living Dangerously” TV series.
