Dina Ganji
Affiliate, Psychiatry and Behavioral Sciences
Visiting Scholar, Psychiatry and Behavioral SciencesBioDina Ganji, MD is a board-certified psychiatrist and Visiting Scholar at Stanford University, working at the intersection of clinical psychiatry, neuropsychiatry, and translational neuroscience. Her research focuses on integrating neuroimaging, neuromodulation techniques, and clinical phenotyping to advance precision psychiatry, with a particular emphasis on autism spectrum disorder, neurodevelopmental disorders, and cognitive neuroscience in children, as well as mood and substance use disorders.
She has a strong and growing interest in autism, pediatric neurocognition, and broader neurodevelopmental conditions, with a particular focus on understanding cognitive and behavioral mechanisms in early development and translating these insights into more individualized and effective interventions.
Dr. Ganji completed her Psychiatry Residency at Mashhad University of Medical Sciences, where she also gained extensive clinical experience in the diagnosis and treatment of a wide range of psychiatric disorders. She is a board-certified psychiatrist with clinical expertise in both inpatient and outpatient psychiatric care.
At Stanford University, she has contributed to multiple interdisciplinary research programs. In Dr. Maldonado’s lab, she serves as a research coordinator for large-scale clinical and longitudinal studies, including delirium outcomes in patients (LUCIDIFY study), psychosocial assessment in transplant candidates (SIPAT project), and clinical cohorts involving CAR-T and hematopoietic stem cell therapy.
Previously, in the Brain Stimulation Lab at Stanford, she gained hands-on experience in transcranial magnetic stimulation (TMS), including motor threshold assessment and clinical application of H-coil protocols in patients with OCD, depression and anxiety disorders. She also received training in functional MRI (fMRI) data acquisition and interpretation through advanced neuroscience courses.
In Iran, she served as Research and Development Lead at Atrin Clinic, where she integrated repetitive TMS (rTMS), pharmacological treatment, and clinical assessment tools for patients with major depressive disorder, generalized anxiety disorder, and substance use disorders, while systematically monitoring treatment outcomes.
Her research output includes multiple peer-reviewed publications in international journals, covering topics such as autism spectrum disorder, neuromodulation in bipolar disorder, congenital heart defects in vulnerable pediatric populations, neurocognitive effects of environmental exposure, and adjunctive treatments in psychiatric disorders.
Beyond research, Dr. Ganji is actively involved in academic service, including conference organization, neuropsychiatry committee activities, and peer review for scientific journals. She has also completed professional training in mind-body medicine approaches.
Dr. Ganji is deeply committed to patient-centered psychiatry and is particularly motivated by understanding autism, neurodevelopmental disorders, and pediatric cognitive neuroscience. She aims to bridge neuroscience and clinical psychiatry to develop more precise, individualized interventions that improve outcomes in children and patients with complex psychiatric and neurodevelopmental conditions. -

Xiaojing Gao
Assistant Professor of Chemical Engineering
Current Research and Scholarly InterestsHow do we design biological systems as “smart medicine” that sense patients’ states, process the information, and respond accordingly? To realize this vision, we will tackle fundamental challenges across different levels of complexity, such as (1) protein components that minimize their crosstalk with human cells and immunogenicity, (2) biomolecular circuits that function robustly in different cells and are easy to deliver, (3) multicellular consortia that communicate through scalable channels, and (4) therapeutic modules that interface with physiological inputs/outputs. Our engineering targets include biomolecules, molecular circuits, viruses, and cells, and our approach combines quantitative experimental analysis with computational simulation. The molecular tools we build will be applied to diverse fields such as neurobiology and cancer therapy.

Leonor García-Bayona
Assistant Professor of Microbiology and Immunology
Current Research and Scholarly InterestsThe human microbiome is evolving rapidly (i.e. over our lifetimes) following changes in modern lifestyles, especially in industrialized countries. The García-Bayona lab seeks to understand how horizontal gene transfer shapes interactions within the human intestinal microbiota and what the implications of this widespread phenomenon are for community properties relevant to human health (for example, the ability of the gut community to recover after antibiotic treatment). There is currently only a superficial understanding of the different cellular roles of most exchanged genes, the mechanisms governing their spread and their effect community dynamics. Our lab works on bridging the existing gap between the current systems-level observational studies and a mechanistic understanding through bacterial genetics and physiology. We take a bottom-up approach (from genes to communities), incorporating genetics, metagenomics, population analyses and experimental evolution in tractable bacterial consortia.
