Dylan Nielson, PhD: Dylan is a staff scientist in the Mood Brain & Development Unit at the National Institute of Mental Health. He has more than ten years of experience in neuroimaging and data analysis starting as a post-baccalaureate research fellow in the NIMH in 2007. He conducted research on neurostimulation, imaging analysis methods, and human memory while completing his PhD at The Ohio State University. After that, he completed a data science fellowship at The Data Incubator before a brief interlude as a mortgage fraud analyst with Freddie Mac. He returned to the NIMH as part of the Data Science and Sharing Team where he contributed to a range of open source neuroimaging tools. As part of the MBDU, Dr. Nielson is leading neuroimaging analyses in the lab and helping with the development of novel tasks and models to explore the interaction of mood and cognition.
Hanna Keren, PhD: With an engineering background and a PhD in dynamics and control of neural network activity, my aim is to utilize computational-engineering concepts to better understand depression mechanisms. Towards this aim, I’m exploring the relation between environmental cues, brain activity, and emotional states. I address these questions in the context of reinforcement learning models and reward processing, and by developing a novel real-time methodology for closed-loop mood control. This control framework would enable the unique study of aberrations in neural dynamics and reward processing during mood transitions.
Georgia O’Callaghan, PhD: I completed my PhD at Trinity College Dublin, Ireland, where I studied impulsivity and risk-taking using a combination of behavioural and neuroimaging techniques. I currently serve as the MBDU's Research Data Officer, regulating data acquisition and providing solutions to data retrieval, integration, quality, storage and management. I have taken lead on the development and maintenance of the clinical database for the team. As part of this I also manage and program our custom online data collection platform.
Dipta Saha, PhD: I am currently working as a postdoctoral research fellow at MBDU. I completed my PhD in theoretical physics at University of Florida. I worked as a postdoctoral research associate (Theoretical/Computational Neuroscience) at Brown University before joining MBDU. I also worked as a Data Scientist before joining Brown University. My current research focuses on building a model that can predict the depressive state of mind using fMRI longitudinal data.I am also interested in the theoretical modeling of human brain states to understand the different states of Mood.
Lucrezia Liuzzi, PhD: I recently joined the MBDU as a postdoctoral fellow. I have a background in physics and completed my PhD at the University of Nottingham in the UK as part of the Magnetoencephalography (MEG) group. The focus of my PhD has been of functional connectivity measures in MEG data, exploring time dynamics of functional networks in whole brain analysis during rest and task, and relating neural oscillations to attention and neurochemistry. As part of the MBDU I aim to study reward processing and mood changes through a multi-modal approach incorporating M/EEG and fMRI methods.
Song Qi, PhD: Song received his PhD in social and decision neuroscience at Caltech, where he studied neural mechanisms underlying fear and anxiety. With a background in engineering and information science, he is broadly interested in human cognition and decision making. In particular, he explores how decision-making behaviors are optimized under threat and social influence, using a combination of ecologically inspired paradigms, BOLD fMRI, and computational modeling. Before moving to the D.C. area, Song was a former New Yorker and beneficiary of LA sunlight. Outside of research, he enjoys literature, sub-cultures, fashion, and video games.
Ken Towbin, MD: Dr. Towbin is the Chief of Clinical Child and Adolescent Psychiatry in the Emotion and Development Branch and a Senior Research Physician in the Intramural Research Program at NIMH.

At Dartmouth, I interrogated relationships between mathematical network formation and disparities in women’s reproductive health. After graduating from Dartmouth, I worked for two years at YWCA USA, a national non-profit dedicated to eliminating racism and empowering women. I hope to continue combining my passions for research and racial/social justice by pursuing a career in the fields of health disparities and epidemiology. Outside of my research, I enjoy cooking, playing ultimate frisbee, and making other people laugh.

I graduated in 2019 from Duke University with a BS in Neuroscience and Minors in Spanish and Music. My research experience has involved graph theory analyses of fMRI data exploring a range of tasks and attributes including creativity, addictions, and counterfactual thinking. I completed an honors thesis my senior year investigating hippocampal integration during counterfactual thinking. I hope to apply these graph theoretical techniques to examine longitudinal changes in the brain network architecture of individuals with depression and anxiety. I plan to continue my research with a Ph.D. in cognitive neuroscience.

I am interested in using longitudinal research to identify risk factors and potential treatments for adolescent depression. In order to pursue these research questions, I hope to get an MD/PhD and go into child and adolescent psychiatry.
Payton Fors: I am a post-baccalaureate IRTA fellow in the Mood Brain Development Unit, headed by Dr. Argyris Stringaris. In spring of 2020, I graduated from Washington University in St. Louis.
