Question: Lewis Hastings Sarett was a research scientist at one of the largest what, in the world?
Context: Paulo Pinheiro is a Brazilian American computer scientist working in the areas of provenance and semantic web in support of sciences.  Paulo has been a research scientist at the Rensselaer Polytechnic Institute's Tetherless World Constellation since 2013.  Between 2011 and 2013, he was a staff scientist at the U.S. Department of Energy's Pacific Northwest National Laboratory.  Between 2006 and 2012, he was an Associate Professor of Computer Science at the University of Texas at El Paso.  Paulo is from a long line of scientists and engineers: his father is a retired professor of material sciences at the Universidade Federal de Minas Gerais; his paternal grandfather was the founding Mine Superintendent of Vale S.A., the second largest mining company in the world and Israel Pinheiro da Silva, a great-grand-uncle, was the chief engineer responsible for the construction of Brasilia, the capital of Brazil. Steve C. Donnellan is the Chief Research Scientist of the Evolutionary Biology Unit at the South Australian Museum.  He is also an Affiliate Professor at the University of Adelaide.  Donnellan moved from New South Wales to South Australia in 1985 to undertake research recovering the evolutionary history of Australia's lizards.  This work led to the establishment of a comprehensive collection of reptile and frog tissues from Australia and New Guinea.  In 1990 Donnellan joined the South Australian Museum's staff and established the DNA laboratory there.  His research since has focused on the evolution and biogeography of Australasian fauna.  Donnellan has used molecular genetic methods to examine issues in the population genetics, phylogeography and phylogenetic relationships of vertebrates and selected invertebrate groups.  Many of his research projects have been supported by the Australian Research Council (ARC).  His work has been published in numerous scientific journals, including "Biological Conservation", "Evolution", "International Journal of Parasitology", "PLOS One", "Restoration Ecology", "Zoologica Scripta" and "Zootaxa". Robert Allan Phillips MD (July 16, 1906 in Clear Lake, Iowa – September 20, 1976) was a research scientist during World War II who developed battlefield methods to evaluate hemoglobin levels using specific gravity saving many lives.  This method is used in blood donor clinics to determine whether a person is healthy enough to donate blood.  Continuing in the Navy his research turned to cholera where he spearheaded the efforts of Naval Medical Research Unit Two to develop a cure for the disease.  He evaluated the course of the disease and developed the protocol for rehydration used today which has saved millions of lives.  His research lead the Lasker Foundation to award him a prize in 1967.  In his retirement, he collaborated with the University of Washington and the Chinese Government doing research in kidney failure again using hydration as a solution in remote areas of China where dialysis was not available. Lewis Hastings Sarett (December 22, 1917 – November 29, 1999) was an American organic chemist.  While serving as a research scientist at Merck & Co., Inc., synthesized cortisone. Prof. Dr. Qamar-Uz-Zaman Chaudhry is a Pakistani meteorologist and research scientist.  He is the current Vice President of World Meteorological Organisation.  He was retired from the position of Director General of Pakistan Meteorological Department on 13 September 2010.  He is a researcher in the field of Meteorology, Atmospheric Sciences, Hydrology and Seismology.  Chaudhry a well-known scientist in Pakistan who has written articles in the fields of Meteorology, Atmospheric Sciences, Hydrology, Seismology, Plate tectonics and earthquakes.  His more than 50 research papers have been published in national and international scientific journals.  He is currently working as Senior Advisor LEAD Pakistan on Climate Change Program. Joseph Andrew Lapointe, also known as Andy Lapointe, was a Senior Research Scientist at Domtar Inc. Research Centre in Senneville Quebec.  He was involved in the development of mechanical processes and equipment at the research level for over 25 years.  During his time at Domtar he specialized in the development of chipping technology and has a number of patents and patents pending in his field.  He assisted in the development of over 30 sawmills improving the quality of their chips to meet the requirements of specific pulp mills.  Prior to joining Domtar, he was with the Pulp and Paper Research Institute of Canada (Paprican) where he co-invented the Papriformer and was involved in its development.  This wet sheet former has been the subject of numerous papers and is considered one of the major advances in papermaking technology.  The Papriformer received the Governor General's award for Engineering Design in 1975.  Andy has also been responsible for a number of analytical devices (sources coming soon) which are in use in universities, research centres and technical laboratories. Daniel Hillel is an Israeli water and soil scientist.  Hillel's development of micro-irrigation techniques has dramatically improved agricultural output and water efficiency in the Negev desert of Israel, across the Middle East, and in chronically dry regions around the world.  Throughout his career, Hillel has used science to bridge cultural and religious divides and improve livelihoods in over 30 countries, including Pakistan, Sudan, Iran, Egypt, Jordan, and Cyprus.  Most recently, he has been researching ways to adjust agricultural techniques in adaptation to increasing water shortages resulting from climate change.  In 2012, he won the World Food Prize.  He is currently working as a senior research scientist at the NASA Goddard Institute for Space Studies at The Earth Institute at Columbia University in New York. Merck & Co., Inc. (), d.b.a. Merck Sharp & Dohme (MSD) outside the United States and Canada, is an American pharmaceutical company and one of the largest pharmaceutical companies in the world. Kevin R. Henke is an American geochemist and former instructor at the University of Kentucky's department of Geology.  He currently works as a senior research scientist at the University of Kentucky's Center for Applied Energy Research.  He is well known for his criticism of young earth creationism and the scientific arguments they make for a young earth.  In particular, he has been critical of the RATE project's results, which claim to show that zircons contain too much helium to be billions of years old, and has argued that Russell Humphreys, a young-earth creationist who was involved in the project, has made errors in his research.  These flaws include that, according to Henke, "The vast majority of Humphreys et al.'s critical a, b, and Q/Q0 values that are used in these "dating" equations are either missing, poorly defined, improperly measured or inaccurate."  Henke has also accused Humphreys of misidentifying his specimens, fudging his data, and not considering the possibility of helium contamination in this research.  He has also criticized John Woodmorappe for arguing that radiometric dating is unreliable.  On one occasion, Henke called Kent Hovind on the phone regarding Hovind's $250,000 challenge to "prove" evolution.  Hovind told Henke that in order to win the money he would have to recreate the Big Bang in a laboratory.  Henke responded by proposing several alternative "proofs" that pertained to geology (his field of expertise), but Hovind refused, saying that the project must be chosen by him and it must not pertain to the area in which Henke has scientific expertise.  Hovind therefore required Henke to prove that dogs and bananas had a common ancestor, and lowered the award to only $2,000 should he succeed.  Henke accepted the challenge, and later drafted a contract, which was then posted on Talk.origins.  However, one of Henke's requirements was that the judges be unbiased, and Hovind rejected the challenge for this reason, insisting that he should be the only one who can choose the judges. Loren C. Carpenter (born February 7, 1947) is a computer graphics researcher and developer.  He is co-founder and chief scientist of Pixar Animation Studios.  He is the co-inventor of the Reyes rendering algorithm and is one of the authors of the PhotoRealistic RenderMan software which implements Reyes and renders all of Pixar's movies.  Following Disney's acquisition of Pixar, Carpenter became a Senior Research Scientist at Disney Research.  He retired in early 2014.
