Question: What were the two fields of study engaged in by a biochemist who taught at a university in Detroit, Michigan for a year and worked on the Manhattan Project?

Context paragraphs:
Medical jurisprudence: Medical jurisprudence or legal medicine is the branch of science and medicine involving the study and application of scientific and medical knowledge to legal problems, such as inquests, and in the field of law.  As modern medicine is a legal creation, regulated by the state, and medicolegal cases involving death, rape, paternity, etc. require a medical practitioner to produce evidence and appear as an expert witness, these two fields have traditionally been interdependent.

Ecotechnology: Ecotechnology is an applied science that seeks to fulfill human needs while causing minimal ecological disrupution, by harnessing and manipulating natural forces to leverage their beneficial effects.  Ecotechnology integrates two fields of study: the 'ecology of technics' and the 'technics of ecology,' requiring an understanding of the structures and processes of ecosystems and societies.  All sustainable engineering that can reduce damage to ecosystems, adopt ecology as a fundamental basis, and ensure conservation of biodiversity and sustainable development may be considered as forms of ecotechnology.

University of Liechtenstein: The University of Liechtenstein (German: Universität Liechtenstein ) is the largest of four centers for higher education in the Principality of Liechtenstein.  It focuses on two fields of study – architecture and business economics.  The University of Liechtenstein is located in Vaduz, the capital of the principality.  The students and faculty come from 40 countries, and the university has partnerships with 80 other institutions.

J. Budziszewski: J. Budziszewski (born 1952) is professor of government and philosophy at the University of Texas, Austin, where he has taught since 1981.  He specializes in ethics, political philosophy and the interaction of these two fields with religion and theology.

Linda Long: Dr. Linda Long is a biochemist and musician, who has combined these two fields to create what she terms molecular music.

Aeroelasticity: Aero elasticity is the branch of physics and engineering that studies the interactions between the inertial, elastic, and aerodynamic forces that occur when an elastic body is exposed to a fluid flow.  Although historical studies have been focused on aeronautical applications, recent research has found applications in fields such as energy harvesting and understanding snoring.  The study of aeroelasticity may be broadly classified into two fields: static aeroelasticity, which deals with the static or steady response of an elastic body to a fluid flow; and dynamic aeroelasticity, which deals with the body’s dynamic (typically vibrational) response.  Aeroelasticity draws on the study of fluid mechanics, solid mechanics, structural dynamics and dynamical systems.

Nathan O. Kaplan: Nathan Oram Kaplan (June 25, 1917 – April 15, 1986) was an American biochemist who studied enzymology and chemotherapy.  After completing a B.A. in chemistry at UCLA in 1939, Kaplan studied carbohydrate metabolism in the liver under David M. Greenberg at the University of California, Berkeley medical school.  He earned his Ph.D. in 1943.  From 1942 to 1944, Kaplan participated in the Manhattan Project, and then spent a year as an instructor at Wayne State University.  From 1945 to 1949, Kaplan worked with Fritz Lipmann at Massachusetts General Hospital to study coenzyme A.  Kaplan went to the University of Illinois College of Medicine as an assistant professor in 1949, and from 1950 to 1957 he worked at the McCollum-Pratt Institute of Johns Hopkins University.  In 1957, he was recruited to head a new graduate program in biochemistry at Brandeis University.  In 1968, Kaplan moved to the University of California, San Diego, where he studied the role of lactate dehydrogenase in cancer.  He also founded a colony of nude mice, a strain of laboratory mice useful in the study of cancer and other diseases.  In 1981, Kaplan became a founding member of the World Cultural Council.

History of geometry: Geometry (from the Ancient Greek: γεωμετρία ; "geo-" "earth", "-metron" "measurement") arose as the field of knowledge dealing with spatial relationships.  Geometry was one of the two fields of pre-modern mathematics, the other being the study of numbers (arithmetic).

Wayne State University: Wayne State University (WSU) is a public research university located in Detroit, Michigan.  Founded in 1868, WSU consists of 13 schools and colleges offering nearly 350 programs to more than 27,000 graduate and undergraduate students.  Wayne State University is Michigan's third-largest university and one of the 100 largest universities in the United States.

Lida Holmes Mattman: Graduated with a M.S. in Virology from the University of Kansas and a Ph.D. in Immunology from Yale University.  Mattman has taught Immunology, Microbiology, Bacteriology, Virology and Pathology.  She worked for 35 years in these fields at various schools and institutions including Harvard University, Howard Hughes Institute, Oakland University and Wayne State University.  She was a Professor Emeritus in the Department of Biological Sciences at Wayne State University in Detroit where she was engaged in research and lecturing.  She has served as President of the Michigan Branch of the American Society for Microbiology, as Chairman of the Medical Division of the Michigan Academy of Sciences, and held various offices in the local chapter of Sigma Xi.
