Joshua D. Grab, MS, MA
Biostatistician 2, Stanford-Surgery Policy Improvement Research and Education Center
BioJoshua Grab is a Biostatistician at the S-SPIRE Center in the Department of Surgery. He has Masters' degrees in Biostatistics and Mathematics.
Josh has 12 years of experience as a biostatistician and data analyst. As a data analyst at UCSF, he worked primarily for the Liver Transplant Center doing survival analyses. At Wake Forest University, he worked on genome-wide association studies for various disease conditions. Before that, he worked at the Duke Clinical Research Institute (DCRI), building logistic models for mortality within the Society of Thoracic Surgeons' National Cardiac Database.
Josh has been a SAS user for all of his time in biostatistics and has beginner to intermediate skills with various other software packages, including R, STATA, and MATLAB, and is learning Python.
In addition to his biostatistics career, Josh also has 7 years of experience teaching mathematics and introductory statistics at the community college level. -

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. -
Teodor Grantcharov, MD, PhD, FACS, FRCS (Glasg)
Professor of Surgery (General Surgery)
BioDr. Teodor Grantcharov is a board-certified, fellowship-trained surgeon specializing in bariatric (weight loss) and minimally invasive surgery. He is also a clinical professor of surgery at Stanford University School of Medicine and associate chief quality officer for innovation and safety at Stanford Health Care.
As a surgeon, Dr. Grantcharov specializes in minimally invasive and bariatric surgery. He is an accomplished researcher and leader in the field of surgical innovation and patient safety. His work has made important contributions in curriculum design, assessments of competence, and impact of surgical performance on clinical outcomes. Dr. Grantcharov developed the surgical Black Box concept, designed to transform safety culture in medicine and introduce modern safety management systems in high-risk operating rooms.
Dr. Grantcharov has published more 220 articles in peer-reviewed journals and given more than 200 invited presentations in Europe and North and South America. He holds several patents and is the founder of Surgical Safety Technologies, Inc.—an academic startup that commercializes the Black Box Platform™. Dr. Grantcharov has received several prestigious honors and awards, including the Queen Elizabeth II Diamond Jubilee Medal for his contributions in clinical research and patient safety in Canada.
Dr. Grantcharov is a fellow of the American College of Surgeons. -
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. -
