Susanna Gunamany
Postdoctoral Scholar, Urology
BioDr. Gunamany received her PhD in Public Health from the Indian Institute of Technology (IIT) Gandhinagar. Before her doctoral studies, she earned a Master of Public Health (MPH) degree from the Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), India, and a Bachelor of Science from the University of Kerala.
Dr. Gunamany's scholarly pursuits revolve around the convergence of health and technology, with a specific emphasis on mobile health (mHealth) and its potential for improving healthcare delivery and access. Broadening her research scope, she is interested in health disparities and inequalities research, focusing on marginalized populations and the intricate interplay of social, economic, and environmental factors influencing health outcomes. -
Ruwan Gunaratne
Instructor, Medicine - Hematology
BioRuwan Gunaratne, MD, PhD is an Instructor in Hematology at Stanford University School of Medicine and a board-certified hematologist-oncologist with a clinical focus on acute myeloid leukemia (AML), myelodysplastic syndromes (MDS), and myeloproliferative neoplasms (MPNs). His clinical and translational research centers on improving disease monitoring in myeloid cancers using personalized circulating tumor DNA (ctDNA) profiling, a blood-based approach designed to more sensitively track measurable residual disease (MRD), assess treatment response, refine risk stratification, and detect relapse earlier across the myeloid disease spectrum. Dr. Gunaratne’s work has been recognized with awards from the American Society of Hematology and the Stanford Cancer Institute, and he is actively committed to advancing precision medicine approaches for patients with myeloid malignancies.

Pankaj Gupta
Postdoctoral Scholar, Neurosurgery
BioPankaj Gupta is a postdoctoral researcher at Stanford University working at the intersection of systems neuroscience, neuroengineering, and computational modeling. His research focuses on understanding how distributed neural circuits generate behavior and how these circuits reorganize during learning and recovery, particularly in the context of motor control and neurological disorders such as stroke.
Pankaj completed his Ph.D. at the University of British Columbia, where he investigated brain–behavior dynamics using widefield and two-photon calcium imaging in mice. His work combined experimental neuroscience with real-time closed-loop systems, enabling the modulation of neural activity through behaviorally contingent feedback. He also developed computational tools and biologically inspired recurrent neural network models to capture large-scale neural dynamics and inter-regional interactions.
At Stanford, his research expands to include large-scale electrophysiology using Neuropixels probes to study cerebellar and subcortical circuits involved in motor control and recovery. He is particularly interested in how neural populations across multiple brain regions coordinate and adapt following injury, and how these insights can inform the design of closed-loop neurostimulation and brain–machine interface systems. -
Neel K. Gupta

Shreya Gupta
Postdoctoral Scholar, Cardiovascular Medicine
Current Research and Scholarly InterestsI am a biomedical researcher focused on understanding the molecular mechanisms governing vascular smooth muscle cell (SMC) behavior in cardiovascular and metabolic diseases. My work investigates how signaling pathways, including Notch3 and Thrombospondin-1, regulate SMC phenotypic switching, fibrous cap stability, and plaque vulnerability in atherosclerosis, with the goal of identifying novel therapeutic targets to prevent heart attacks and strokes.

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. -
