Question: What Plasmodium organism is Raymond G. Chambers an envoy for?

Context paragraphs:
USS S-17 (SS-122): USS "S-17" (SS-122) was a second-group (S-3 or "Government") "S"-class submarine of the United States Navy.  Her keel was laid down on 19 March 1918 by the Lake Torpedo Boat Company in Bridgeport, Connecticut.  She was launched on 22 May 1920 sponsored by Mrs. Raymond G. Thomas, and commissioned on 1 March 1921 with Lieutenant Commander Charles S. Alden in command.

Plasmodium berghei: Plasmodium berghei is a protozoan parasite that causes malaria in certain rodents. Originally, isolated from thicket rats in Central Africa, "P. berghei" is one of four "Plasmodium" species that have been described in African murine rodents, the others being "Plasmodium chabaudi", "Plasmodium vinckei", and "Plasmodium yoelii".  Due to its ability to infect rodents and relative ease of genetic engineering, "P. berghei" is a popular model organism for the study of human malaria.

Raymond G. Perelman: Raymond G. Perelman is the billionaire Founder, Chairman and CEO of the RGP Holdings.  He is the father of Ronald O. Perelman and Jeffrey E. Perelman.  He is known for his philanthropy and charitable giving, as well as his close ties with the city of Philadelphia and the University of Pennsylvania.

Plasmodium molecular tools: Plasmodium molecular tools are a set of methods for the genetic manipulation of "Plasmodium" genus of parasites. " Plasmodium" species have been difficult to scientifically study, partially due to the inability to use many standard biological techniques to genetically manipulate the organism.  Recent research has sought to overcome these technical barriers in order to make the parasite more amenable to study.  Below is a description of published methods of genetic control within the "Plasmodium" parasite.

Butch Feher: Raymond G. "Butch" Feher (born May 19, 1954 in Flint, Michigan) is a retired professional basketball shooting guard as a member of the Phoenix Suns (1976–77).  He attended Vanderbilt University where as a member of the school's basketball team he scored 30 points three separate times.  He was drafted by the Suns during the second round of the 1976 NBA draft.

Malaria: Malaria is a mosquito-borne infectious disease affecting humans and other animals caused by parasitic protozoans (a group of single-celled microorganisms) belonging to the "Plasmodium" type.  Malaria causes symptoms that typically include fever, tiredness, vomiting, and headaches.  In severe cases it can cause yellow skin, seizures, coma, or death.  Symptoms usually begin ten to fifteen days after being bitten.  If not properly treated, people may have recurrences of the disease months later.  In those who have recently survived an infection, reinfection usually causes milder symptoms.  This partial resistance disappears over months to years if the person has no continuing exposure to malaria.

Ray Chambers: Raymond G. Chambers (born August 7, 1942) is a philanthropist and humanitarian who currently serves as the United Nations Secretary-General's Special Envoy for Health in Agenda 2030 and for Malaria.  Chambers' philanthropic efforts are diverse, with major focus areas in global health, mentoring, and revitalizing his home city of Newark, New Jersey.

Raymond Frey: Raymond G. Frey ( ; 1941–2012) was a Professor of Philosophy at Bowling Green State University, specializing in moral, political and legal philosophy, and author or editor of a number of books, including "Interests and Rights: The Case Against Animals" (1980), "Euthanasia and Physician-Assisted Suicide" (1998, with Gerald Dworkin and Sissela Bok), and "The Oxford Handbook of Animal Ethics" (2011, with Tom Beauchamp, eds.) .

Epiphyte: An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it.  Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur like any other organism.  They are an important source of food for many species.  Typically, the older parts of a plant will have more epiphytes growing on them.  Epiphytes differ from parasites in that epiphytes grow on other plants for physical support and do not necessarily negatively affect the host.  An epiphytic organism that is not a plant is sometimes called an epibiont.  Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads).  Epiphyte species make good houseplants due to their minimal water and soil requirements.  Epiphytes provide a rich and diverse habitat for other organisms including animals, fungi, bacteria, and myxomycetes.

Jeffrey E. Perelman: Jeffrey E. Perelman is the billionaire Founder, Chairman and CEO of the JEP Management holding company.  He is the son of Raymond G. Perelman, and the younger brother of Ronald O. Perelman.  He is primarily known for his investing and philanthropic activities.
