Ali Rahimpour Jounghani
Research Scientist, Psychiatry and Behavioral Sciences - Interdisciplinary Brain Sciences
BioMy long-term research interests lie in advancing our understanding of neuroimaging techniques and their application in mapping developmental pathways of brain networks, with a focus on how alterations in these networks contribute to mental health disorders. My academic training and multidisciplinary research background have provided me with expertise in a range of neuroimaging modalities, including functional MRI (fMRI), structural MRI, electroencephalography (EEG), and functional near-infrared spectroscopy (fNIRS).
During my doctoral studies, I investigated the effects of contextually specific, action-based timing behavior on brain responses, as well as the functional impacts of timing behavior in cochlear implant users. These studies provided valuable insights into the temporal dynamics of brain function. My research has also extended to clinical and cognitive applications, such as studying brain functionality in infants in neonatal intensive care units and in adults with brain disorders.
Currently, as a research scientist at Stanford University, my work bridges psychiatry, cognitive science, and biomedical engineering. I focus on refining neuroimaging data analysis techniques and advancing the use of fNIRS and MRI to explore developmental cognition, particularly for ADHD. A significant part of my current research involves the development of a wearable, cost-effective fNIRS platform for precision mental health. Through my work, I aim to contribute to a deeper understanding of brain disorders and to create practical, cutting-edge tools that advance precision mental health care. -

Hannah Elizabeth Raila
Adjunct Clinical Instructor, Psychiatry and Behavioral Sciences
BioDr. Hannah Raila's training focuses the "diet" of visual information that we consume as we navigate the world (e.g., do we see the crack in the wall, or do we pass by it unaware?), the factors that predispose us to detect this emotional information in our environment the first place, and how this diet of information influences our emotions. To study our visual biases and how they relate to how we feel, she leverages tools from cognitive psychology - including eye tracking and continuous flash suppression (CFS).
As a postdoctoral researcher in Dr. Carolyn Rodriguez's lab, she is particularly interested in links between visual attention and emotion in OCD, and whether biased visual processing of obsession-related cues contributes to symptom severity. -

Nilam Ram
Professor of Communication and of Psychology
BioNilam Ram studies the dynamic interplay of psychological and media processes and how they change from moment-to-moment and across the life span.
Nilam’s research grows out of a history of studying change. After completing his undergraduate study of economics, he worked as a currency trader, frantically tracking and trying to predict the movement of world markets as they jerked up, down and sideways. Later, he moved on to the study of human movement, kinesiology, and eventually psychological processes - with a specialization in longitudinal research methodology. Generally, Nilam studies how short-term changes (e.g., processes such as learning, information processing, emotion regulation, etc.) develop across the life span, and how longitudinal study designs contribute to generation of new knowledge. Current projects include examinations of age-related change in children’s self- and emotion-regulation; patterns in minute-to-minute and day-to-day progression of adolescents’ and adults’ emotions; and change in contextual influences on well-being during old age. He is developing a variety of study paradigms that use recent developments in data science and the intensive data streams arriving from social media, mobile sensors, and smartphones to study change at multiple time scales. -

Sneha Ramakrishna
Assistant Professor of Pediatrics (Hematology/Oncology)
BioSneha Ramakrishna obtained her B. A. from the University of Chicago and her M.D. from the Cleveland Clinic Lerner College of Medicine at Case Western Reserve University. In medical school, through the Howard Hughes Medical Research Scholar Award, she joined Dr. Crystal Mackall’s laboratory, where she designed and developed various GD2 CAR-Ts and tested them in preclinical models. During her residency training in Pediatrics at the Children’s Hospital of Philadelphia, she cared for some of the first patients treated with CD19 CAR T cells, learning the power of this therapy first-hand. During her fellowship in Pediatric Hematology/Oncology at the Johns Hopkins/National Cancer Institute combined program, she worked with Dr. Terry Fry. She evaluated the mechanism of CD22 CAR T cell relapse in patients by developing an antigen escape model and establishing a deeper understanding of the effects of antigen density on CAR-T phenotype, expansion, and persistence (Fry…Ramakrishna…Mackall Nat Med, 2018; Ramakrishna, et al., Clinical Cancer Research, 2019). Since arriving at Stanford, Dr. Ramakrishna leads an interdisciplinary team that designs, develops, and successfully implements a robust correlative science platform for our novel CAR-T therapies. Analyzing patient samples from our first-in-human GD2 CAR-T trial (NCT04196413) treating a universally fatal cancer, diffuse midline glioma (DMG), we identified that intracerebroventricular CAR-T administration correlates with enhanced pro-inflammatory cytokines and reduced immunosuppressive cell populations in cerebrospinal fluid as compared to intravenous CAR-T administration (Majzner*, Ramakrishna*, et al., Nature 2022 *co-first authors). Her research program evaluates unique sets of patient samples using novel single-cell immune profiling to identify the drivers of CAR-T success or failure. Building on these findings, her team assesses approaches to enhance CAR-T efficacy and translate these findings to the clinic.
Clinically, Dr. Ramakrishna cares for children with solid tumors and treats hematologic, solid, and brain tumor pediatric patients with CAR T cell therapies in the Cancer Cellular Therapies program.
