Felix Horns
Assistant Professor of Genetics
BioFelix Horns is an Assistant Professor of Genetics at Stanford University and a Core Investigator at Arc Institute. The Horns group works at the interface of synthetic biology and genomics to develop and apply technologies for monitoring and manipulating cells, with particular focus on the immune system and the brain.
Felix earned his B.A. in Biology from Amherst College and his Ph.D. in Biophysics working with Dr. Stephen Quake at Stanford, where he developed and used single-cell genomics, high-throughput sequencing, and computational analysis approaches to understand the origins of human antibody diversity and to discover principles of how brain circuits assemble during development. He then joined Dr. Michael Elowitz's lab at the California Institute of Technology where he combined synthetic biology and genomics approaches to develop RNA packaging, secretion, and delivery systems, which open new avenues for understanding and controlling cellular behaviors. -

Hadi Hosseini
Associate Professor (Research) of Psychiatry and Behavioral Sciences (Interdisciplinary Brain Science Research)
Current Research and Scholarly InterestsOur lab’s research portfolio crosses multiple disciplines including computational neuropsychiatry, cognitive neuroscience, multimodal neuroimaging and neurocognitive rehabilitation. Our computational neuropsychiatry research mainly involves investigating alterations in the organization of connectome in various neurodevelopmental and neurocognitive disorders using state of the art neuroimaging techniques (fMRI, sMRI, DWI, functional NIRS) combined with novel computational methods (graph theoretical and multivariate pattern analyses).
The ultimate goal of our research is to translate the findings from computational neuropsychiatry research toward developing personalized interventions. We have been developing personalized interventions that integrate computerized cognitive rehabilitation, real-time functional brain imaging and neurofeedback, as well as virtual reality (VR) tailored toward targeted rehabilitation of the affected brain networks in patients with neurocognitive disorders. -
Kristene Hossepian, Psy.D.
Clinical Assistant Professor, Psychiatry and Behavioral Sciences - Child & Adolescent Psychiatry and Child Development
BioDr. Kristene Hossepian is a licensed clinical psychologist with expertise in anxiety, depression, eating disorders, parent management training, and stress. During her doctorate training at the PGSP-Stanford Psy.D. Consortium she received extensive training in a number of evidence-based treatment approaches for children and adolescents, such as Cognitive Behavioral Therapy, Dialectical Behavioral Therapy, and Acceptance and Commitment Therapy. She completed her pre-doctoral internship at Lucile Packard Children’s Hospital/Children’s Health Council where she worked with youth struggling with severe eating disorders, chronic medical conditions, trauma, depression, and anxiety. After receiving her doctorate in 2020, Dr. Hossepian completed her postdoctoral fellowship at the Stanford University School of Medicine, where she continued to receive training in evidence-based treatments for youth with a variety of presenting problems at the inpatient and outpatient level.
Currently, Dr. Hossepian is a Clinical Assistant Professor within the Division of Child and Adolescent Psychiatry at the Stanford University School of Medicine. She works alongside Dr. Mary Sanders and Dr. Jennifer Derenne at the Comprehensive Care Program serving children and adolescents who are medically compromised due to complications with their eating disorders. Additionally, Dr. Hossepian works within Dr. Victoria Cosgrove’s Stress, Resilience, Emotion, and Mood (StREam) Laboratory to identify the ways that psychobiological stress responsivity is implicated in the emergence and propagation of affective symptomatology. Dr. Hossepian is interested in exploring the physiological mechanisms underlying mood disorders and eating disorders as well as providing children and adolescents with novel emotion regulation strategies. -

Michael R. Howitt
Assistant Professor of Pathology and of Microbiology and Immunology
On Leave from 02/16/2026 To 07/17/2026Current Research and Scholarly InterestsOur lab is broadly interested in how intestinal microbes shape our immune system to promote both health and disease. Recently we discovered that a type of intestinal epithelial cell, called tuft cells, act as sentinels stationed along the lining of the gut. Tuft cells respond to microbes, including parasites, to initiate type 2 immunity, remodel the epithelium, and alter gut physiology. Surprisingly, these changes to the intestine rely on the same chemosensory pathway found in oral taste cells. Currently, we aim to 1) elucidate the role of specific tuft cell receptors in microbial detection. 2) To understand how protozoa and bacteria within the microbiota impact host immunity. 3) Discover how tuft cells modulate surrounding cells and tissue.

Anna Howley
Ph.D. Student in Immunology, admitted Autumn 2024
BioAnia Howley is an Immunology PhD student. She received her BS in Biology from College of the Holy Cross in 2022, where she investigated the function of APOBEC3G variants in the context of HIV infection. After completing her degree, she joined the Wyss Institute for Biologically Inspired Engineering at Harvard University. Using an organ-on-chip model, she studied the effects of radiation-induced injury on human bone marrow and developed an in-vitro model of Shwachman Diamond Syndrome using shRNA-based knockdown in primary CD34+ progenitor cells.

Alyssa Michelle Howren
Postdoctoral Scholar, Epidemiology
BioAlyssa Howren is a Postdoctoral Scholar at Stanford University’s Department of Epidemiology and Population Health in the School of Medicine. She completed her MSc and PhD training at the University of British Columbia’s Faculty of Pharmaceutical Sciences during which she was a trainee at Arthritis Research Canada. Her PhD training was supported by a Canadian Institutes of Health Research (CIHR) Doctoral Award, along with UBC’s Wayne Riggs Interdisciplinary Scholarship in Pharmaceutical Sciences and Andrew Nord Fellowship in Rheumatology. Her research focuses on using multiple data sources to provide evidence to disentangle the complex relationship between depression and anxiety with inflammatory arthritis and assess how people living with inflammatory arthritis are treated for their comorbid mental disorders. Methodological approaches in Dr. Howren’s work have included systematic reviews, qualitative research, mixed methods, and population-based studies using linked administrative health databases. She was awarded a CIHR Fellowship for her postdoctoral research at Stanford University which aims to evaluate whether biases in clinical decision-making contribute to the sex and gender differences observed in the diagnosis of major depressive disorder.
