Receiving a Sloan Foundation Fellowship in 1959, Bhaumik went to the University of California Los Angeles (UCLA) for post doctoral studies. In 1961, he joined the Quantum Electronics Division at Xerox Electro-Optical Systems in Pasadena and began his career as a laser scientist. Concurrently, he taught Quantum physics and Astronomy at the California State University at Long Beach. In 1968, he was enlisted by the Northrop Corporate Research Laboratory, where he rose to become the director of the Laser Technology Laboratory and led a team that made contributions in research on excimer laser technology. One of the papers on this research was presented at the Denver, Colorado meeting of the Optical Society of America in May 1973. At this meeting, Dr.Bhaumik presented substantial evidence to demonstrate for the first time that an excimer laser could be efficient and powerful enough for practical utilization. The application of excimer lasers in Lasik eye surgery has resulted in vision correction in many cases. The most widespread application of excimer laser has been in photolithography, a critical technology used in the manufacturing of microelectronic devices like cell phones. His contributions to the development of new and high power lasers merited his election by his peers to be a fellow of both the American Physical Society and the Institute of Electrical and Electronics Engineers.
Bhaumik’s current interest is performing innovative researchin deciphering the century old enigma of quantum physics as well as sharing with the public the advances in quantum physics and cosmology and their implications for our lives, work, technology, and spiritual development. This he endeavors to do through books such as the Code Name God and The Cosmic Detective, articles, lectures, and TV programs like the Cosmic Quantum Ray. He is also interested in research on the origin and the nature of consciousness and how that knowledge can be utilised in improving the quality of our existence.
Bhaumik has published over fifty papers in various professional journals and is a holder of a dozen laser-related U.S. patents. He has been invited to lecture all over the world, at forums including: Summer School on High-Power Gas Lasers, Capri, Italy 1975; International Symposium on Gas-Flow and Chemical Lasers, Belgium 1978; International Symposium on Gas Discharge Lasers, Grenoble, France 1979; Asoke Sarkar Memorial Lecture, Calcutta International Book Fair 2001; Institute of Culture, Calcutta, India 2006; Kolkata Society for Asian Studies, Kolkata, India 2015.
His search spanned a decade and led him to the inference that the One Source at the hub of all spiritual traditions is grounded in scientific reality and not a mere creation of blind faith. He also argues that science and spirituality are indeed two sides of the same coin, the coin being that unique human consciousness that allows us to perceive both ourselves and objective reality.Therefore, he argues in his book Code Name God (Crossroads Publishing), the big divide between science and spirituality can be bridged. The trick, Bhaumik asserts, is to see things in an entirely new light–a light shed upon by the recent revelations of quantum physics and cosmology. He now devotes much of his time and energy to bringing this message to the public, including its younger members, for whom he has recently published The Cosmic Detective (Penguin 2008), a primer on cosmology, and created an animated television series, Quantum Ray, shown on the HUB channel.
Bhaumik has instituted an annual International Award through the UCLA Neuropsychiatry Institute to acknowledge the best scientific evidence demonstrating the effect of mind in healing. He has been involved in numerous community activities through his association with the Los Angeles Bombay Sister City Association; the Los Angeles St. Petersburg Sister City association; the Long Beach Calcutta sister City Association and others. He has donated to various charitable organizations including the Thalians of Los Angeles. He also established the Bhaumik Educational Foundation, based in Kolkata, which provides full scholarships to needy but brilliant students who wish to apply themselves to studies in science and technology.he has also made an $11 million gift to UCLA to establish an Institute of Theoretical Physics.
