Assistant Professor in the Child Study Center; Associate Director, Albert J. Solnit Integrated Training Program

Biography

I direct a program of research on model systems of early brain development and am particularly interested in the impact of prenatal genetic and environmental factors on childhood behavioral problems and how early events in brain development relate to the onset of major mental illness, such as depression and schizophrenia, in adolescence and adulthood. The long term goals of my research program are to better understand the etiologies of child and adult mental illnesses and to improve outcomes...

The long term goals of my research program are to better understand the etiologies of child and adult mental illnesses and to improve outcomes for pregnant mothers affected by mood and anxiety disorders.

Line Brotnow

Postgraduate Fellow

After a double bachelor’s degree in psychology/sociology from University of Paris, I finished my Msc in Developmental Neuroscience from Yale/UCL in 2013. My dissertation focused on constructing and testing a conceptual model of prenatal maternal psychosocial stress and coping. This year, I will be involved in a project exploring prenatal and genetic influences on externalizing behavior, using both human and animal data. After my fellowship I wish to pursue a doctoral degree in clinical...

Rebecca Fine

Postgraduate Research Assistant

Rebecca Fine graduated from Yale University in 2012 with a B.S. with distinction in the neuroscience track of psychology.  As an undergraduate, she worked with Dr. Amy Arnsten studying the molecular pathways underlying working memory and how they are disrupted during stress.  Her current projects focus on the mechanisms by which prenatal stress exerts effects on inhibitory neuron development, with a particular focus on microglia.  Rebecca hopes to pursue a Ph.D. in molecular biology.

Polona Jager

Masters Student

I am a postgraduate student from University College London, taking a year of research in the Stevens lab as part of my masters degree in developmental neuroscience with a focus on psychiatric disorders. My project is looking at dopaminergic neurodevelopmental events in prenatally stressed offspring and how that correlates with ADHD symptoms. I became interested in neuroscience during my undergraduate degree in Biochemistry at Imperial College London and would like to do a PhD and...

Sreya Radhakrishna

Postgraduate Research Assistant

Sreya Radhakrishna graduated from the University of California, Berkeley in 2013 with a B.A. in Molecular and Cell Biology, emphasis in Neurobiology. Her project in the Stevens lab focuses on identifying the molecular mechanisms underlying the behavioral phenotype in the branched-chain ketoacid dehydrogenase kinase (BCKDK) autism mouse model. She hopes to pursue a career in medicine and research in the future.

Abigail Sawyer

Research Assistant

I am an undergraduate student at Colorado College, Colorado Springs, CO. I have worked as a research assistant in the Stevens lab over the summer in 2012 and 2013, first studying the interaction of prenatal stress with genetic deficits in fibroblast growth factor receptors in affecting behaviors relevant to psychiatric disorders and now examining the developmental course of neuroanatomy affected by these same variables. I hope to pursue a Ph.D. in neuroscience.

Erinma Kalu

Research Assistant

I am an undergraduate student at Yale University majoring in Molecular, Cellular, and Developmental Biology. I am dual-enrolled in the Yale School of Public Health and am currently earning a combined BA/MPH degree with a concentration in Chronic Disease Epidemiology. My project in the lab involves FGF receptor mutations and prenatal stress. Outside of the lab, I am involved with the Yale Gospel Choir and Yale-Ecuador HIV Clinic Initiative. After graduating, I will pursue a career in...

Daniela Rhaklina-Powsner

Research Assistant

I have worked as a high school research assistant at the lab in the Child Study Center in the summer of 2012 and 2013. I have been involved in the evaluation of the fibroblast growth factor transgenic knock out at different time points during development. I plan to attend college in the fall of 2013 to study molecular biology and Japanese, and continue with my vocal studies.

Jie "Jacky" Zhang

Postgraduate Fellow

Jacky came from Shantou University Mental Health Center, Guangdong, China and worked as postgraduate fellow at the Department of Psychiatry, Yale University for 18 months from 10/31/2011. Jacky is very interested in identifying neurobiological, molecular, and cellular mechanism underlying neurodevelopmental dysfunction induced by perinatal stress. In the Stevens lab, he was actively involved in the project that investigates the function of astroglial cell and GABAergic system...
