Matthew Gunther, MD, MA
Clinical Assistant Professor, Psychiatry and Behavioral Sciences - Medical Psychiatry
Clinical Assistant Professor (By courtesy), Medicine - Primary Care and Population HealthCurrent Research and Scholarly InterestsDr. Gunther’s scholarly work focuses on neuropsychiatric syndromes arising in the context of medical illness, with particular emphasis on delirium, catatonia, psychopharmacology in the medically ill, and the psychiatric sequelae of critical illness. His research spans the identification, assessment, and management of acute brain dysfunction in hospitalized and critically ill populations, including studies evaluating delirium prediction tools, bedside diagnostic instruments, and neurorecovery outcomes following medical insults. He has contributed to the validation and clinical application of the Stanford Proxy Test for Delirium (S-PTD) and related delirium risk stratification efforts, and has authored systematic reviews and case-based scholarship addressing catatonia, alcohol withdrawal syndromes, and medication-related neurotoxicity. In parallel, Dr. Gunther’s work in integrated behavioral health and medical education examines how psychiatry-led, skills-based interventions can improve recognition of neuropsychiatric and trauma-related symptoms in primary care and inpatient medical settings. Across these domains, his research emphasizes translational, clinically grounded approaches that equip non-psychiatric clinicians to manage complex neuropsychiatric presentations with greater confidence and precision.

Brooke Gurland, MD, FACS
Clinical Professor, Surgery - General Surgery
BioPelvic floor and functional bowel disorders refer to a series of symptoms and anatomic findings that effect men and women of all ages. These may include: constipation, difficult evacuation, fecal incontinence, irritable bowel disorders, diarrhea, pelvic organ prolapse, urinary and sexual dysfunction and pain. Although not life threatening, these disorders can severely affect quality of life and individual performance.
Over the past two decades I have dedicated my career to working with other specialists for comprehensive care for individuals with pelvic floor disorders. In July 2017, I joined The Department of Surgery, Division of Colorectal Surgery at Stanford University as the Medical Director of the Pelvic Health Center. I previously spent the prior decade at Cleveland Clinic running a multidisciplinary clinic and performing over 200 combined procedures in conjunction with colleagues in urology and urogynecology. We developed a robotic surgical approach to woman with vaginal and rectal prolapse and performed many surgeries to repair intestinal and rectal fistula (abnormal communications between the intestine and vagina).
Prior to that I established a Pelvic Floor Center at Maimonides Medical Center received a Jahnigan Career Development Award looking at multicompartment prolapse in elderly women. In addition to performing surgery and teaching throughout my career, I have maintained a commitment to long-term follow up of patients after surgery.
Although my training and focus is around surgical techniques and solutions for anorectal disorders and pelvic health, I believe that prevention, non-surgical alternatives, diet, exercise, and behavior management are vitally important to patient success.
One of my many goals is to educate patients, health care providers, and trainees about pelvic floor disorders.
When I am not at work I enjoy quality time with my three teenagers, dog, friends and I practice yoga. -

Richard Haarburger
Postdoctoral Scholar, General Internal Medicine
BioRichard Haarburger is a postdoctoral scholar in the Department of Medicine (Primary Care and Population Health) at Stanford University, working in the lab of Pascal Geldsetzer. He studies questions at the intersection of epidemiology, health policy, and applied econometrics, with a focus on causal inference in large real-world health datasets.
His current work uses quasi-experimental and survival analysis methods to evaluate how preventive interventions (e.g. herpes zoster vaccinations) affect neurological outcomes such as dementia incidence at the population level. He also develops empirical strategies for dealing with challenges common in observational health data, including treatment effect heterogeneity, incomplete outcome follow-up, and competing risks.
Richard’s broader research interests include impact evaluation methods, causal machine learning, and the health and economic consequences of new technologies. During his PhD in quantitative economics, he worked on measurement bias in health surveys, high-dimensional forecasting, and heterogeneity in technology adoption. -

Pardes Habib
Instructor, Neurosurgery
BioPardes Habib, MD/PhD, is an Instructor in the Department of Neurosurgery at Stanford University School of Medicine. His research focuses on how human neural stem cells (hNSCs) drive brain repair after chronic stroke. By integrating state-of-the-art imaging (MRI/PET) with spatially resolved multi omics, he maps structural and molecular remodeling after stroke and aims to identify diagnostic and prognostic biomarkers that drive the development and refinement of precision, cell-based therapies.
Dr. Habib completed dual doctorates in Neurology/Neuroscience (MD/PhD) and Biochemistry (PhD) at RWTH Aachen University in Germany, where he later earned a Habilitation (Venia Legendi) in Experimental Neurology—an academic qualification comparable to an associate professorship.
As head of Aachen’s Translational Stroke Research Group, he investigated neuroprotective and neuroinflammatory pathways and illuminated the roles of inflammasome activation and the unfolded protein response in acute ischemic stroke.
Since joining Dr. Gary Steinberg’s laboratory at Stanford in 2022, Dr. Habib has focused on decoding the molecular crosstalk among hNSCs, immune cells, and host neural circuits. His long-term goal is to transform these insights into targeted interventions that restore function and quality of life for patients living with the aftermath of stroke. -
