Laura Graham
Other Teaching Staff-Hourly, Surgery
BioI am an epidemiologist and health services researcher with nearly 20 years of experience in surgical outcomes research. My work focuses on improving healthcare delivery and outcomes for Veterans and other vulnerable populations, particularly those who are older or medically complex. Using large administrative datasets from the Veterans Health Administration (VA), I study surgical processes and outcomes to inform system-level improvements.
With postdoctoral training in health economics and implementation science, I bring expertise in causal inference methodology and artificial intelligence, particularly the use of natural language processing (NLP). I apply these methods to extract insights from unstructured clinical data and to strengthen causal analyses in complex healthcare datasets. These approaches allow me to address research questions that were previously difficult to study with standard empirical approaches.
As a collaborative leader, I have mentored junior investigators and worked across academic and industry sectors to advance health services research. My goal is to translate evidence into practice, ultimately improving the quality of surgical care for Veterans. -

Nathanael S. Gray
Krishnan-Shah Family Professor
BioNathanael Gray is the Krishnan-Shah Family Professor of Chemical and Systems Biology at Stanford, Co-Director of Cancer Drug Discovery Co-Leader of the Cancer Therapeutics Research Program, Member of Chem-H, and Program Leader for Small Molecule Drug Discovery for the Innovative Medicines Accelerator (IMA). His research utilizes the tools of synthetic chemistry, protein biochemistry, and cancer biology to discover and validate new strategies for the inhibition of anti-cancer targets. Dr. Gray’s research has had broad impact in the areas of kinase inhibitor design and in circumventing drug resistance.
Dr. Gray received his PhD in organic chemistry from the University of California at Berkeley in 1999 after receiving his BS degree with the highest honor award from the same institution in 1995. After completing his PhD, Dr. Gray was recruited to the newly established Genomics Institute of the Novartis Research Foundation (GNF) in San Diego, California. During his six year stay at GNF, Dr. Gray became the director of biological chemistry where he supervised a group of over fifty researchers integrating chemical, biological and pharmacological approaches towards the development of new experimental drugs. Some of the notable accomplishments of Dr. Gray’s team at GNF include: discovery of the first allosteric inhibitors of wild-type and mutant forms of BCR-ABL which resulted in clinical development of ABL001; discovery of the first selective inhibitors of the Anaplastic Lymphoma Kinase (ALK), an achievement that led to the development of now FDA-approved drugs such as ceritinib (LDK378) for the treatment of EML4-ALK expressing non-small cell lung cancer (NSCLC); and discovery that sphingosine-1-phosphate receptor-1 (S1P1) is the pharmacologically relevant target of the immunosuppressant drug Fingomilod (FTY720) followed by the development of Siponimod (BAF312), which is currently used for the treatment of multiple sclerosis.
In 2006, Dr. Gray returned to academia as a faculty member at the Dana Farber Cancer Institute and Harvard Medical School in Boston. There, he has established a discovery chemistry group that focuses on developing first-in-class inhibitors for newly emerging biological targets, including resistant alleles of existing targets, as well as inhibitors of well-validated targets, such as Her3 and RAS, that have previously been considered recalcitrant to small molecule drug development. Dr. Gray’s team developed covalent inhibitors of the T790M mutant of EGFR inspired the development of Osimertinib (AZD9291), now FDA approved for treatment of patients with relapsed lung cancer due to resistance to first generation EGFR inhibitors. Dr. Gray has also developed structure-based, generalized approaches for designing drugs to overcome one of the most common mechanisms of resistance observed against most kinase inhibitor drugs, mutation of the so-called "gatekeeper" residue, which has been observed in resistance to drugs targeting BCR-ABL, c-KIT and PDGFR.
In 2021, Dr. Gray joined Stanford University where he has joined the Stanford Cancer Institute, Chem-H and the Innovative Medicines Accelerator (IMA) to spur the development of prototype drugs.
These contributions have been recognized through numerous awards including the National Science Foundation’s Career award in 2007, the Damon Runyon Foundation Innovator award in 2008, the American Association for Cancer Research for Team Science in 2010 and for Outstanding Achievement in 2011 and the American Chemical Society award for Biological Chemistry in 2011, and the Nancy Lurie Marks endowed professorship in 2015 and the Paul Marks Prize in 2019, and the Hope Funds for Cancer Research in 2023. -

Brooke Gurland, MD, FACS
Clinical Professor, Surgery - General Surgery
BioPelvic floor and functional bowel disorders encompass a wide range of symptoms and conditions that affect people of all ages and genders. These include constipation, obstructed defecation, fecal incontinence, rectal prolapse, pelvic organ prolapse, irritable bowel disorders, and urinary and sexual dysfunction. While rarely life-threatening, these conditions profoundly affect quality of life, self-confidence, and daily function — and they deserve the same serious, compassionate attention as any other illness.
I am a colorectal surgeon and lifestyle medicine physician specializing in anorectal disorders and pelvic floor dysfunction. I serve as Research Director of the Stanford Pelvic Health Center, where I lead a multidisciplinary program that brings together colorectal surgery, urogynecology, urology, gastroenterology, and pelvic floor physical therapy to provide integrated, whole-person care.
My surgical training was at Cleveland Clinic, where I spent nearly a decade building and leading a multidisciplinary pelvic floor clinic and performing hundreds of combined procedures with colleagues in urology and urogynecology. I was among the early adopters of robotic surgical techniques for women with combined vaginal and rectal prolapse, and developed expertise in complex procedures including repair of intestinal and rectovaginal fistula. Earlier in my career, I established a Pelvic Floor Center at Maimonides Medical Center, where I received a Jahnigan Career Development Award studying multicompartment prolapse in elderly women. I joined Stanford's Department of Surgery, Division of Colorectal Surgery in 2017.
My research spans surgical outcomes, pelvic floor quality of life, and patient-centered technology. I am the principal investigator for the Stanford Pelvic Health Registry, a longitudinal database of over 475 patients with rectal prolapse followed since 2018. I was a 2020–2021 Stanford Biodesign Fellow, and my current work includes development and validation of disease-specific patient education tools. I believe that patients who understand their condition make better decisions — and recover better too.
I am also board-certified in lifestyle medicine. Prevention, diet, exercise, pelvic floor physical therapy, and behavior change are not secondary to surgery in my practice — they are the first line of care. Surgery, when it is needed, works best in patients whose lifestyle has been optimized. This philosophy guides how I counsel patients and how I train the next generation of surgeons and clinicians.
When I am not in the clinic or operating room, I can be found at the farmers market, fermenting something in my kitchen, practicing yoga, or spending time with my dog. -

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. -
Laura Michele Hack
Assistant Professor of Psychiatry and Behavioral Sciences (Public Mental Health and Population Sciences)
BioDr. Laura M. Hack is an Assistant of Psychiatry and Behavioral Sciences at Stanford University and the Veterans Affairs Palo Alto Health Care System (PAVAHCS). As Associate Director of the Novel & Precision Neurotherapeutics Program at the Stanford Center for Precision Mental Health, Dr. Hack leads a translational, patient-centered research group that designs and implements mechanistic clinical trials for biologically informed subtypes of Mood, Anxiety, and Trauma-related Disorders (MATRDs).
Her work spans repurposed pharmacologic interventions (e.g., guanfacine), neuromodulation techniques (e.g., repetitive transcranial magnetic stimulation [TMS]), and therapies involving altered states of consciousness (i.e., ketamine, MDMA, psilocybin, and anesthesia-induced dreaming). Across these modalities, Dr. Hack's focus is on tailoring treatment based on objective, biologically anchored markers that match the patient’s profile.
Dr. Hack also directs the Stanford Precision Psychiatry Clinic, a high-touch, high-tech consultation service designed to support individuals with a primary diagnosis of major depression and often comorbid MATRDs. This clinic integrates the investigational use of high-definition neuroimaging (personalized brain circuit scores) with symptom profiling, neurocognitive testing, pharmacogenomic analysis, inflammatory biomarkers, and standard blood work. The aim is to generate individualized insights that inform treatment decisions and help patients better understand the biological underpinnings of their condition—often reducing self-blame and empowering engagement in care.
In her role as Deputy Director as well as Ketamine and Education Lead of the Precision Neuromodulation Clinic (PNC) at PAVAHCS, Dr. Hack specializes in delivering evidence-based, FDA-cleared interventions including TMS and intranasal ketamine for Veterans experiencing treatment-resistant depression, frequently in the context of comorbid PTSD. -
