Attached

helping my development as a clinician and a researcher; Dr. Daniel
Schechter, Principle Investigator in the Parent-Child Project at
Columbia, who introduced me to attachment-based therapy with
children and parents in the therapeutic nursery; Dr. Abby Fyer, from
whom I learned a great deal in conversations over the years, and who
taught me about the importance of the opioid system in attachment;
Dr. Clarice Kestenbaum, for teaching me how to work with children
and young adults in a very special way; and Dr. David Schaffer, who
made my research career possible.
I also thank Dr. Dolores Malaspina, who taught me the basics of
epidemiological research and the importance of community samples
in medicine; Dr. Bill Byne, who discussed with me the literature on
childhood gender nonconformity and taught me how to read scientific
literature in a critical way; and Drs. Ann Dolinsky, David Leibow, and
Michael Liebowitz, for the clinical teachings, knowledge, and
experience they shared with me. Thanks to Dr. Rene Hen for his
support through the years; to Dr. Myron Hofer, whose approach to
studying development in animal models and whose work on the effects
of early attachment on the adult phenotype are exemplary. I value his
confidence in my work, and appreciate his guidance.
I would like to express my appreciation and admiration to my current
collaborators, Dr. Eric Kandel, Dr. Denise Kandel, Dr. Samuel
Schacher, and Dr. Claudia Schmauss. Working with them challenges
my intellect and thinking in the best possible way.
Special thanks to the late Dr. Jimmy Schwartz, who gave me my first
opportunity to perform neuroscience research; to Dr. Herb Kleber, for
his open-door policy and illuminating discussions; to Dr. Francine
Cournos, my first long-term therapy supervisor, for all the support she
has given me over the years; and to all the friends and colleagues with
whom I have been fortunate to work and from whose wisdom I have
benefited.
I thank the National Institutes of Health for ongoing support of my
research, which has contributed to the writing of this book.
I would like to express special gratitude to my family. Having them
as a secure base gives me the courage to explore the world. And last
but not least, I thank all my patients, children and adults alike, for
