Special Programs Designed to Help You Succeed

The Virginia Research Institute (PVT) Limited offers a college preparatory diploma and official GED® testing. The GED® Test that allows one to receive the equivalency of a USA high school diploma. The GED® Test is delivered in the USA, Canada, and over 60 additional countries. What are the benefits of taking the GED® Test? The benefits of taking the GED® Test are vast, but there are certainly 3 main benefits of which you should be aware. (1) The test proves that students have high school academic skills and are able to write and understand English at a 12th grade level. This is especially useful when preparing to pursue higher education at English-speaking institutions that would require TOEFL or other tests to prove a working knowledge of English. (2) You will be eligible to pursue higher education in the USA, since 98% of USA colleges accept the GED® Test credential in place of a high school diploma for admission purposes. (3) You will be eligible to earn a job in the USA, since 96% of USA employers recognize the GED® Test qualification as equivalent to a high school diploma when considering a candidate for employment.

The administration and the faculty of VRI, USA, and VRI, Sri Lanka are supported by internationally and nationally recognized personnel. Take a look at the background of some of our personnel, below:

Mr. Lakshman Perera –  Lakshman Perera is an expert in chemistry, and his successful application of his knowledge has been proven time and time again in his ventures. He holds a Bachelor of Science with honors from the University of Colombo, and is a chartered chemist, member of the Institute of Chemistry, Ceylon, and a member of the American Chemical Society. He was also the last Sinhalese chemist in Paranthan prior to the civil war. Mr. Perera has not only proven his abilities in chemistry, but has also proven his devotion to the field through his numerous, original research projects and inventions. For instance, he found a disinfectant to kill the H5N1 virus, which is Bird Flu, from chicken feces, which was recognized as a highly difficult process, due to the high percentage of calcium that was present.

Mr. Perera’s research and work has pertained to a wide range of topics, such as adhesives, auxiliaries for paints, textile auxiliaries, paper sizing chemicals, medical supplies for the Health Ministry when he manufactured the hospital disinfectant known as Lysol BP, and more. He also holds a patent for the title, “Method of Manufacturing of Low Aromatic White Spirits.” Mr. Perera’s work has provided more employment opportunities in Sri Lanka, saving of foreign exchange to the country, and has also brought about much recognition in the international market.

Professor Sellappulige Rexy Denzil Rosa – Sellappulige Rexy Denzil Rosa is a renowned academic with an extensive professional background in physics. Consequent to completing his Ph.D. in Nuclear Physics at the University of Pittsburgh, he ventured into the field and ultimately gained many outstanding distinctions and recognitions. Some of his notable achievements include being the President of the Institute of Physics from 2004 – 2006, being appointed member/consultant by the Ministry of Education to develop year ten to thirteen physics syllabi, acting as the President of the international physics Olympiad, and acting as the editor of the Sri Lankan journal of physics, in addition to other similar achievements.

He has taught for over twenty-five years and has participated in more than one hundred science days that were organized by various schools across Sri Lanka. He is a member of the Institute of Physics, UK, Institute of Physics, Sri Lanka, and the Sri Lanka Association for the Advancement of Science. Rosa has made extensive literary contributions; in fact, his work was translated into Tamil and English by popular demand. His academic and professional excellency was further recognized in 2011 when he was nominated for the World Summit Award.

Professor Eugene de Silva – Eugene de Silva has been an educator for over 25 years. As a professor of physics and chemistry, he developed online courses in the fields of physics, chemistry, ecology, environmental science, intelligence, security, terrorism studies, research, etc. He established the National Accrediting Commission for Martial Arts (NACMA)- a registered charity- and Virginia Research Institute (VRI) – a non-profit organization in the United States in 2004. These foundations were set in place to spark the younger generation’s interest in furthering their education and research. He has been the President of the Tennessee Science Department Chairs Association since 2008. He is also the Chair of Institute of Physics UK/USA Branch (South Eastern USA). He is an Executive Member of the Tennessee Academy of Sciences. De Silva has written several books including textbooks in physics and chemistry and is an internationally recognized educator with his name entered in the Who’s Who in the World, Who’s Who in American Education, and Who’s Who in America. He developed the first Martial Arts educational degree in the world in 1993 when he was in the UK. He holds the highest Dan grade in martial arts and is the founder of an international charity known as The Society of Martial Arts, UK. He, as a practitioner of martial arts, introduced a syllabus of teaching physics through martial arts in 2007. He introduced Physics Day in the USA, which has been in place since 2005 for high school students where mechanics section of physics is taught through martial arts. He has also won the “Innovative Teaching Award,” “Above and Beyond Award,” and has received recognition awards from the Tennessee Academy of Sciences, USA and the Institute of Chemistry, Sri Lanka. He is a chartered chemist, chartered scientist, and chartered physicist; he was also elected as a fellow of the Royal Society for the encouragement of Arts, Manufactures, and Commerce in recognition of his outstanding work in the field of education. The World Head of Family Sokeship Council also inducted him to the Hall of Fame in 2001 in Florida, USA. His novel teaching model, “START,” is now being introduced in the teaching of science through the Virginia Research Institute. He also holds two world records in breaking cinder blocks on different parts of his body.

Professor Emmanuel Essuman – Dr. Emmanuel Essuman obtained his PhD in Inorganic Materials Chemistry/Materials Science and Engineering from the University of Oslo (UiO), Norway and has degrees (MSc and BSc (Hons)) in Chemical Engineering with emphasis on Process Engineering and Energy Technology from University of Applied Sciences, Bremerhaven, Germany. At the Kwame Nkrumah University of Science and Technology, Kumasi Ghana he was awarded a Bachelors of Science degree in Mechanical Engineering. Dr. Essuman currently holds the adjunct faculty position at Walters State Community College. Dr. Essuman is also the current treasurer of the TASDC. He has previously worked at several leading research laboratories including Oak Ridge National Laboratory (ORNL) Oak Ridge TN, Center for Materials Science and Nanotechnology at the University of Oslo Norway, and Forschungszentrum Juelich GmbH (Research Center Juelich Co.
