Vincenzo Sanguineti, MD,  was born in Eritrea and lived there until completion of Medical School at the "Universita' Degli Studi" in Milan, Italy. He then spent five years in Nigeria, where he conducted published field research in Tropical Medicine and directed a missionary hospital. He profited from the prolonged exposure to uncontaminated natural habitats and from the degrees of difference and similarity among different species and different human cultures, which enhanced his fascination for the interaction between the unique subjectivity of the self and the interactive processes stemming from the profound complexity of the individual and collective variables.  Currently, Dr. Sanguineti is in private practice in Philadelphia, where he is Associate Professor in the Department of Psychiatry at Jefferson Medical Center of the Sidney Kimmel Medical College.
