Adam Eichenbaum

Ph.D. student, Psychology: Cognitive Neuroscience, UC Berkeley

The D'Esposito Lab

Advisor: Dr. Mark D'Esposito

Email: eichenbaum@berkeley.edu

I am a fourth-year neuroscience graduate student at the University of California – Berkeley in Mark D’Esposito’s neuroimaging lab. As a psychology undergraduate at the University of Wisconsin – Madison, I researched working memory and cognitive training with Brad Postle and C. Shawn Green. My current research in the D’Esposito lab examines how humans build and extract structure from their environment in order to facilitate learning in novel settings. With the use of functional magnetic resonance imaging and computational modeling, I aim to discover the neural underpinnings of how these cognitive structures are built, represented, and implemented. By understanding the manner by which humans build internal models of their world, I hope to ultimately advance the field of cognitive training and rehabilitation.

Jacquelyn Ellison

Ph.D. student, Psychology: Cognition and Development, Emory University

Concept Mining Lab

Advisor: Dr. Phil Wolff

E-mail: jacquelyn.ellison@emory.edu

I am a second year graduate student in Dr. Phil Wolff's lab, working in collaboration with Dr. Patricia Bauer. My research asks how the particulars of language use influence the acquisition of knowledge and skills; as language is both perceived and produced, I am also interested in how it influences its own acquisition. Using big-data computational methods, behavioral studies and ERP, I seek to understand how information is structured in the linguistic environment and how this structure influences learning.

Kristina Dahlgren

Ph.D. student, Psychology: Cognition and Development, Emory University

Hamann Cognitive Neuroscience Lab

Advisor: Dr. Stephan Hamann

E-mail: kristina.dahlgren@emory.edu

My research uses functional magnetic resonance imaging to investigate the neural correlates of emotional modulation of memory. In particular I am interested in understanding how emotion and stress can result in both impairments and enhancements of memory. I am also interested in how emotion and stress affect different stages of memory including: encoding, consolidation, retrieval, and re-consolidation.

Ana Maria Hoffmann

Ph.D. student, Psychology: Cognition and Development, Emory University

Bauer Memory at Emory Lab

Advisor: Dr. Patricia Bauer

E-mail: ana.maria.hoffmann@emory.edu

I am a second year graduate student in the Bauer Memory Development Lab. I completed my undergraduate at the University of San Francisco, where I majored in Psychology and minored in Neuroscience. My current research interests include the development of semantic memory across childhood and into adulthood and the processes involved in knowledge extension through information integration. Particularly, I am interested in the impact of second language learning on semantic memory.

Neural Plasticity Research Laboratory

Advisor: Dr. Michael Borich

E-mail: erin.michele.king@emory.edu

I am currently a third year graduate student in the Neuroscience PhD program at Emory. My research uses transcranial magnetic stimulation (TMS) to investigate different neurological processes that occur in primary and secondary sensorimotor areas. More specifically, I am interested in understanding neuroplastic mechanisms that underlie motor skill learning with the hope of using this knowledge to enhance rehabilitative outcomes for individuals after stroke.

Yuan Meng

Ph.D. student, Psychology: Neuroscience and Animal Behavior, Emory University

Berkeley Early Learning Lab

Advisor: Fei Xu

Email: yuan_meng@berkeley.edu

I am a third-year graduate student at UC Berkeley where I work with Dr. Fei Xu in the Berkeley Early Learning Lab. Broadly, my research looks at how children drive their own learning, in both more constrained cases such as choosing the right interventions to learn causal structures and less constrained ones like learning from free play. Recently, I also became interested in examining whether similar mechanisms may play a part when children learn about their social world.

James McGregor

Ph.D. student, Neuroscience, Emory University

Sober Laboratory

Advisor: Dr. Sam Sober

E-mail: james.neal.mcgregor@emory.edu

I am a fourth year graduate student pursuing my Ph.D. at Emory University in Dr. Samuel Sober's Lab. As an undergraduate, I majored in neuroscience and biology and minored in chemistry at Brandeis University, where I was a member of Dr. Gina Turrigiano's lab studying synaptic plasticity in rodent visual cortex. As a Ph.D. candidate in Dr. Sober's lab, my research has focused on neural circuit mechanisms underlying reward and aversive reinforcement learning of complex, skilled behaviors. I use multiple neuroscience techniques and exploit a unique model system - the songbird - to study how the brain processes sensory feedback to guide motor learning.

Mansheej Paul

Ph.D. student, Applied Physics, Stanford University

Neural Dynamics and Computation Lab

Advisor: Surya Ganguli

Email: mansheej@stanford.edu

I am an Applied Physics Ph.D. student at Stanford University working in Surya Ganguli’s lab. I am fascinated by how the collective dynamics of the billions of neurons in our brain can give rise to such complex processes as strategizing and decision making. To understand this, I use and develop tools from high dimensional statistics and deep learning to investigate how reinforcement learning algorithms can be represented and implemented in both artificial and real neural networks. Before delving into neuroscience, I was an Applied Mathematician at Brown University where I studied how theories of quantum gravity can be modeled by random matrices. I also enjoy playing around with algorithmic music generation, play writing, watching musical theatre, and making desserts.

Jeanne Powell

Ph.D. student, Psychology: Neuroscience and Animal Behavior, Emory University

The Kelly Lab

Advisor: Dr. Aubrey Kelly

Email: jeanne.m.powell@gmail.com

Jeanne Powell received her BA in Biological Sciences and Psychology from Cornell University in 2017. As an undergraduate, her research focused on how paternal absence impacts social development and exploration in the bi-parental prairie vole. Upon graduating, she began work as a Post-baccalaureate IRTA Fellow at the National Institute of Environmental Health Sciences, where she studied the neuroanatomy of the noradrenergic system in mice using viral-genetic and digital strategies. In the Fall, Jeanne will join the Neuroscience and Animal Behavior Program in Dr. Aubrey Kelly’s Comparative Social Neuroscience Lab. She is excited to employ computational, behavioral, and neurological strategies to explore social behavior in the altricial prairie vole and precocial spiny mouse.

April Ratliff

Ph.D. student, Neuroscience, Emory University

Laboratory

Advisor: Dr. Mar Sanchez

Email: april.darcy.ratliff@emory.edu

I am a third year PhD candidate in the Neuroscience Program at Emory University. My research aims to study adolescence as a developmental period of enhanced neuroplasticity using a rhesus macaque model. I am particularly interested in examining the mechanisms by which various stress and sex hormones may facilitate or inhibit the maturation of neural connections between cortical and limbic regions in the brain, in turn affecting different aspects of learning, memory, and emotional regulation. I hope to use this knowledge to advance our understanding and treatment of adolescents who may be at risk for developing long-term psychiatric diseases.

Steve is interested in the overlap between psychology and consumer technology, and he hopes to develop this intersection through his research.

Ahmed Roman

Ph.D. student, Physics, Emory University

Theoretical Biopyhsics Lab

Advisor: Dr.Ilya Nemenman

Email: ahmed.hemdan.roman@emory.edu

I am a third-year physics graduate student in the Nemenman Lab. I am interested in understanding the dynamics of associative learning in animals. In particular, I model how the round worm C. elegans uses associative memory between food and temperature to navigate its environment across multiple time scales. We aim to prove that operant conditioning and classical conditioning are implemented in the brain of the nematodes through two distinct biological pathways. I am also interested in probability matching in bees: a foraging strategy where the bees visit flowers in proportion to the nectar produced the flowers. I employ experiments, computation and theory to understand these dynamics.

Arick Wang

Ph.D. student, Psychology: Neuroscience and Animal Behavior, Emory University

Bachevalier Lab

Advisor: Jocelyne Bachevalier

Email: arick.wang@emory.edu

I am a PhD candidate in the Neuroscience & Animal Behavior program at Emory University under the guidance of Dr. Jocelyne Bachevalier. In collaboration with the Marcus Autism Center, I study the development of early social-visual engagement in infant rhesus macaque monkeys (macaca mulatta) by eye-tracking them while during the first 6 months of life. I hope to help bridge the gap between brain and behavior during this sensitive time in social development. In my free time I enjoy going on hikes with my dog, cooking, competitive bar trivia, and being an enthusiastic supporter of Atlanta United.

Her research focuses on the development of memory from infancy through childhood, with special emphasis on the determinants of remembering and forgetting; links between social, cognitive, and neural developments and age-related changes in autobiographical or personal memory; and self-derivation of new factual knowledge through integration of separate yet related episodes of new learning. She is the Co-Director of the National Institutes of Health T32 “Mechanisms of Learning across Development and Species.”

Robert R. Hampton

Ph.D. Psychology, University of Toronto

Laboratory of Comparative Primate Cognition

E-mail: robert.hampton@emory.edu

Our lab studies memory and cognition in nonhuman primates. Our experiments help define the relationship between human and nonhuman memory, and identify the neural substrates of memory. Our comparative work addresses questions about the evolution of memory and cognition, while our basic neuroscience research contributes to the knowledge base needed to develop treatments for diseases affecting memory and cognition in humans. Our laboratory has done a lot of work on metamemory and metacognition in monkeys. More recently we have focused on studies of the mental representation of sequences and other ordered stimuli. We have recently initiated a new research program addressing cognition in wild birds. I co-direct, with Dr. Patricia Bauer, the National Institutes of Health T32 “Mechanisms of Learning across Development and Species.”
