Nim Tottenham

Tottenham attended the Hopkins School, a private school in New Haven, Connecticut. Her teachers at Hopkins championed her to partake in laboratory experiences at nearby Yale University. At Yale, she learned about genetic signaling in drosophila in Spyros Artavanis-Tsakonas' lab and the role of neuropeptides in parental cognitions of their newborns in James Leckman's lab. She attended Barnard College, where she majored in Psychology and earned her B.A. in 1996. Following her graduation, she worked as a research assistant in the laboratory of Mary Jane Rotheram-Borus. She helped examine the development of children and adolescents in New York City whose parents were living with or had died from HIV-related illness. Working on these projects influenced her interest in early life experiences on emotional development. She also spent one summer training at the University of Pittsburgh. Here she was introduced to the study of psychopathology during the adolescent period under the mentorship of Ron Dahl. to examine developmental change in amygdala-prefrontal cortex circuitry under normal conditions as well as following early adversity. In 2017, Tottenham was selected to be the featured presenter for the Irene Jakob Memorial Lecture series, which was established at the University of Pittsburgh in honor of the late Irene Jakab, a psychiatrist and humanist who had achieved prominence for her use of art therapy in the diagnosis and treatment of learning disabilities and mental illness. == Research ==

Tottenham studies the critical windows that affect how the brain develops. Her lab at Columbia uses various methods to understand the development of neural circuits that dictate behavior through childhood and adolescence and the effects of early-life caregiving and stress have on brain development. Tottenham found that children who spent extended amounts of time in institutionalized care developed an abnormal frontolimbic circuitry, both functionally and structurally, which reduced their ability to maintain eye contact and caused anxiety symptoms. One of her most cited works includes The NimStim set of facial expressions: Judgments from untrained research participants. The NimStim Set of facial Expressions is a broad dataset comprising 672 images of unnaturally posed photographs by 43 professional actors. It is widely known in the literature, especially in the field of working memory, self-regulation, and even in the treatment of clinical disorders such as schizophrenia. She is currently exploring the longitudinal development of the amygdala and its cortical connections, the impact of early life stress on brain development, and how children learn to respond to emotional or frustrating events from their parents. == Representative publications ==
