Nader began work at the Maharishi Ayurveda Health Center in 1987[4] and in 1994, published his first book, Human Physiology: Expression of Veda and the Vedic literature.

[12][13] He earned his Ph.D. from the Massachusetts Institute of Technology (MIT) in the field of Brain and Cognitive Science[14][15] and became a visiting physician at their Clinical Research Center.

[6][16][17] Nader has conducted research in hormonal activity, neurochemistry, neuroendocrinology, on the medical role of the neurotransmitter and on the relationship between age, behavior, diet, seasonal influences and mood.

[11] Nader reports that his desire to have a complete understanding of the mind and body and its relationship to consciousness and the human physiology led him to a "spiritual awakening" and the study of Vedic science with the Maharishi.

[11] In 1986, Nader was criticized for overstating his post-graduate connections to MIT and implying that his research was sanctioned by his alma mater.

"[22] The book has been described as an attempt at documenting the scientific basis of the Maharishi's "interpretation of Advaita Vedanta and thus the Vedas … by relating neuroanatomy and neurophysiology to Vedic astrology and philosophy".

[25][26][7][27] In 2002, Nader was invited by the mayor of Maharishi Vedic City to take residence at The Mansion Hotel, which serves as the capital of the conceptual Global Country of World Peace.

[2] In 2012, Nader was the keynote speaker on a tour of 10 cities in North American, entitled "A New Paradigm: Veda, Consciousness, the Ramayana, and the Self".
