Fateme (Fatima) Nateghi
Postdoctoral Scholar, Biomedical Informatics
BioAs a postdoc researcher at the Division of Computational Medicine, I find myself at the exciting intersection of machine learning and healthcare. My journey began with a PhD in Biomedical Sciences from KU Leuven in Belgium, where I explored the complexities of machine learning algorithms and their transformative potential in clinical settings. My research focused on adapting these algorithms for time-to-event data, a method used to predict when specific events may occur in a patient’s future.
At Stanford, my work centers on building trustworthy AI systems to enhance healthcare delivery. I develop and evaluate machine learning models that integrate structured electronic health records (EHRs) and unstructured clinical notes to support real-world clinical decision-making. My recent projects include predicting treatment retention in opioid use disorder, improving antibiotic stewardship for urinary tract infections, and enabling digital consultations through large language models (LLMs). I'm particularly interested in embedding-based retrieval and retrieval-augmented generation (RAG) methods that help bridge cutting-edge AI research with clinical practice.
My role involves not just advancing the integration of machine learning in healthcare but also collaborating with a diverse team of clinicians, data scientists, and engineers. Together, we're striving to unravel complex healthcare challenges and ultimately improve patient outcomes. -

Vaidehi Natu
Physical Sci Res Scientist
Current Research and Scholarly InterestsDr. Vaidehi Natu is a developmental neuroscientist. Her research program aims to study how the human brain matures from infancy to adulthood, as it acquires new life skills and behaviors: What are the origins of the cellular and molecular mechanisms of brain development during infancy? How does the trajectory of neural mechanisms unfold during development, as school-aged children acquire complex skills such as reading or face recognition? What are some of the parallels in brain development across primate species? What changes occur in the brain in developmental disorders such as autism, multiple sclerosis, and dyslexia?
She uses a multi-modal approach by combining various neuroimaging techniques including functional magnetic resonance imaging (fMRI), quantitative MRI (qMRI), and diffusion MRI (dMRI) as well as behavioral observations, histology, comparative methods across humans and macaques, and intracranial electroencephalography. Combining complementary techniques provides a unified understanding of how the brain’s anatomy, function, and behavior co-develop to achieve complex human skills. -

Ashkan Nazari
Ph.D. Student in Music, admitted Autumn 2023
Iranian Studies Student Assistant, Iranian StudiesBioAshkan Nazari
Degrees / Education
M.A., Ethnomusicology, Tehran University of Art, Tehran, 2016
B.A., Music, University of Tehran, Tehran, 2012
A Kurdish-Iranian musician, multi-instrumentalist, improviser, composer, and researcher, Ashkan is currently a PhD candidate in ethnomusicology and a doctoral certificate student in composition at Stanford University. Ashkan’s compositional work draws on the Iranian dastgāh system and Kurdish maqām idioms, while his practice at Stanford engages contemporary and experimental compositional approaches.
Ashkan’s more than 15-year research career has centered on Kurdish classical and folk musics as well as Iranian classical music. At Stanford, his work explores intersections between music and genocide, war, violence, intellectual movements, Islam, and Kurdish identity. He is also interested in developing decolonial ethnographic approaches to maqām as a cultural–musical practice and concept, particularly in relation to ethnicity and racism.
In his quest to explore those realms, Ashkan has already been prolific back home, with two titles: The Concept and Structure of Maqām in Kurdish Music, The Structure of Musical Modes in Hawrāmi Music. His articles have appeared in leading Iranian journals, and he has presented his research at international ethnomusicology conferences.
As the founder and conductor of the first philharmonic orchestra in his Kurdish hometown of Paveh, Ashkan has also taught Iranian music theory and directed Iranian ensembles, and has instructed setār performance and the analysis of Iranian classical music at the University of Kurdistan and the University of Art and Culture in Kermanshah and Sanandaj, respectively.
