Sleep research has been very good to me! From a small-town childhood, I landed at Gettysburg College, where I studied psychology, played field hockey and tennis, and made many life-long friends. I then moved west and was a research assistant at the Stanford Sleep Lab before attending graduate school at Stanford Medical School from 1976 to 1979, receiving a Ph.D. in neuro- and biobehavioral sciences, specializing in sleep research. I worked with Dr. William C. Dement and many other wonderful scientists and students at Stanford before moving to RI to start my own research group in 1985. At Bradley Hospital and Brown University, I have been privileged to perform research supported by the NIMH, NINR, NHLBI, NIDA, NCI, NIAAA, NASA, NSF, the Sleep Research Society Foundation, Periodic Breathing Foundation, and the Grass Foundation. I have also had the great pleasure of working with a terrific group of scientists, trainees, research participants, and their families. My science has also garnered me invitations to travel all over the US and Canada, to many European countries, as well as to Israel, Saudi Arabia, Japan, Latin America, and Australia. Do science and see the world, I say! Finally, I love summertime. Thus, when it’s February in New England, you’ll find me in Adelaide, South Australia living the endless summer dream.

I grew up in Rhode Island before heading to Baltimore, MD to earn a BA in Psychological and Brain Sciences from the Johns Hopkins University. After my first year of college, I was lucky enough to work for Dr. Carskadon as a Dement Fellow, and I’ve been fascinated by sleep ever since. After working in the behavioral sleep medicine laboratory of Dr. Michael Smith at Hopkins, I moved to California and earned my PhD in Psychology from the University of California at Berkeley in the laboratory of Dr. Matthew Walker. My graduate work combined structural and functional MRI, quantitative EEG, and cognitive paradigms to examine the mechanisms underlying individual-differences in sleep and its associated cognitive functions—primarily in the domain of declarative learning and memory. In 2014, I returned to Dr. Carskadon’s laboratory at Brown as a NIMH T32 Fellow in Child Mental Health, going on to join the faculty of Brown Medical School in 2016. My current work combines the tools of cognitive neuroscience with those of child psychiatry to elucidate how sleep, and sleep loss, contribute to the deficits in cognition observed in children with ADHD. Outside the lab, you’ll likely find me in the kitchen or tending to the BBQ, and occasionally attempting to run fast(er).

Postdoctoral STAR T32 Research Fellow, Department of Psychiatry and Human Behavior, Alpert Medical School of Brown University

I grew up in Tucson Arizona and received my BA in Psychology and MPH in Maternal and Child Health from the University of Arizona. While at the University of Arizona, I had the pleasure of working in Dr. Richard Bootzin's, Dr. Connie Beck's, and Dr. Patricia Haynes' labs where I expanded my knowledge on sleep, health, and early life adversity. I later moved to Baltimore Maryland to complete my PhD in psychiatric epidemiology at the Johns Hopkins Bloomberg School of Public Health with Dr. Adam Spira. There I continued to study early life exposures, sleep, and health, and for my dissertation work I examined the development of infant circadian rest-activity rhythms and their links with maternal bonding and infant temperament. in 2017 I moved to Providence Rhode Island as a Childhood Stress, Trauma, and Resilience (STAR) NICHD postdoctoral research fellow, and am mentored by Dr. Stephanie Parade and Dr. Mary Carskadon. Outside of the lab I love spending time with my cats Taz, Chewie, and Elsa, gardening, and getting out into nature.

Postdoctoral research fellow, Sleep And NeuroDevelopment Program; Department of Psychiatry & Human Behavior, Alpert Medical School of Brown University

I was born at Mountain Home Air Force Base, Idaho, and I grew up mainly in Italy and Germany (with a brief period in Pennsylvania) until age 11, when my family and I settled in Arizona. I completed my Bachelor’s degree in Molecular-Cellular Biology and Psychology at the University of Arizona in Tucson, where I was fortunate to have my first experiences in sleep and neurodevelopmental research with Drs. Jamie Edgin and Lynn Nadel in the Down Syndrome Research Group. After completing an honors thesis exploring background genetic correlates of ADHD profiles in Down syndrome, I moved to Cornell University in Ithaca, NY, where I completed my Ph.D. with Dr. Michael Goldstein examining social contributions to infant attentional organization using micro-behavioral and experimental methods. In2018, I joined the laboratory of Dr. Rebecca Spencer as a postdoc, where I gained deeper insights into the crucial role of sleep for memory and learning across early development. I am excited to continue my work in developmental sleep science here at the Sleep for Science Research Lab with Dr. Jared Saletin, as I help to investigate how sleep loss impacts brain connectivity and cognitive functioning in children with and without ADHD. Outside of the lab, you may find me exploring the outdoors, admiring local art, or curled up on a couch playing video games with my partner and family.

Data Coordinator, E.P. Bradley Sleep and Chronobiology Research Lab.

My father was in the military so I grew up in a lot of different places. I was born in Naples, Italy and from there we moved to Dallas, Texas. My family ultimately settled in Portland, Oregon when I was 13, and most of my family still lives there. I graduated from the University of Oregon with a BA in Psychology. I worked as a counselor with adolescents in Oregon and in San Francisco. My husband and I moved to Rhode Island in 2001 and I’ve been working in research since then. Initially I worked at Brown’s Department of Psychiatry and Human Behavior, and recently I was at the Centers for Behavioral and Preventive Medicine at The Miriam Hospital. I’ve always had in interest in better understanding the relationship between lifestyle, stress and health outcomes. I am excited to learn more about the science of sleep and the complexities of the data collected in the lab. Outside the lab I enjoy music, movies, traveling, and exploring all the natural beauties Rhode Island has to offer.

After growing up in beautiful Northern California and Athens, Greece, I made the long journey to New England for my undergraduate studies. Following my time at Tufts University, which culminated in a BS in Biopsychology, I headed down to Rhode Island to join the exciting new COBRE Center for Sleep and Circadian Rhythms in Child and Adolescent Mental Health. I previously interned at Massachusetts General Hospital’s HPRIR Program, working to develop mind-body interventions, including CBT for insomnia, to promote resiliency in cancer survivors. When I’m off the clock, I fancy daydreaming, lounging in the sun with a book in hand, and saucing it up in the kitchen or on the basketball courts.

Hello everyone! I grew up in New York City and received my BA in Neuroscience & Behavior from Barnard College on the Upper West Side. I kept busy in the city, whether that be from playing in water polo competitions, picnicking in Central Park, or working at the Kellendonk lab studying developmental mouse models of schizophrenia. As an undergrad, I wrote my thesis on the effects of developmental inhibition of the striatal indirect pathway on motivation and dopamine release in the nucleus accumbens. In the Summer of 2023, after passing my driver's test, I moved north to spacious Rhode Island where I now spend my time working with human participants in the Sleep Lab. I have welcomed the change of scenery and pace of life since moving and I enjoy my days baking, Top Golfing, and exploring the various libraries in the Ocean State!
