Dr. Sherwood Waldron is a psychoanalyst, in practice in New York since 1966, teaching as well at Mt. Sinai and at the New York Psychoanalytic Institute, where he trained in adult and child psychoanalysis. Previously he studied psychology as an undergraduate at Harvard, then after his MD at Yale Medical School trained in psychiatry and child psychiatry at Albert Einstein College of Medicine.

He has had a major interest for decades in the evaluation of the efficacy of psychotherapy and psychoanalysis. An NIMH sponsored project on outcomes of childhood neuroses was followed by a thirty-year project to develop a collection of recorded psychoanalyses and psychotherapies. He founded  the Psychoanalytic Research Consortium to study the relationships between what patient and therapist contribute and benefit. This effort has been supported by grants from the American Psychoanalytic Association and the International Psychoanalytic Association, among others, and has the largest database in the world of recorded psychoanalyses. Currently the group is looking to apply natural language processing and artificial intelligence to digest this large database, and look for reliable ways of identifying early in treatment whether and to what degree the patient is likely to benefit from this treatment.

Karl Stukenberg, Ph.D.

Dr. Stukenberg is a practicing psychoanalyst and board certified clinical psychologist in Cincinnati, OH.  He is a faculty member at the Cincinnati Psychoanalytic Institute where he is the chair of the curriculum committee. He is an Associate Professor at Xavier University’s School of Psychology.  His graduate training in clinical psychology was at the Ohio State University, followed by an internship at the Baylor College of Medicine in Houston and three years of postdoctoral training at the Menninger Clinic, which, at the time, was in Topeka Kansas.  He has been a licensed clinician since 1991.

Dr. Stukenberg has studied psychopathology and character structure, including the relationship between stress and pathology as well as the measurement of personality and character structure using the MMPI, the Rorschach and other instruments.  He has worked with the PRC for the past fifteen years to better understand the relationship between the process of what highly trained and skilled psychoanalysts actually do with their analysands in treatment and the well-being and analytic functioning of those individuals.  The questions that he is currently addressing include how the alliance (the working relationship), the abilities of the patient, and the attitude of the analyst towards the patient are related to the patient’s functioning and well-being.

Over the years, she has worked clinically in different settings within the National Health Service, in the UK as well as at a psychoanalytic community clinic in San Francisco.

She has co-authored an introductory book on clinical psychology, chapters on process-outcome research and research in clinical psychology and has written several peer reviewed empirical and review papers on the role of in-session affect experiencing and attunement in psychotherapy, psychodynamic and psychoanalytic treatments.

Katie is now an Assistant Professor at Ferkauf Graduate School of Psychology, Yeshiva University, New York, where she teaches courses on evidence-based psychodynamic psychotherapy, interpersonal psychodynamic psychotherapy and research design to the doctoral students in the clinical psychology program. Her research interest is in psychodynamic psychotherapy as well as its potential moderators and mediators of change. In order to operationalize the (non)verbal psychodynamic processes, students in her research lab learn about several observational coding systems of unconscious processes & therapist techniques. This facilitates data-collection for potential research projects and most importantly also aids clinical skills.
