    Clinical Assistant Professor, Urology

    BioDr. Gulla is a board-certified urologist with fellowship training in endourology. She is a clinical assistant professor in the Stanford University School of Medicine Department of Urology.

    For each patient, she develops a comprehensive, compassionate care plan customized to individual needs. Her goal is to help each patient achieve the best possible health and quality of life.

    Dr. Gulla performs the complete spectrum of diagnostic and treatment procedures for urological conditions. She treats disorders including benign prostatic hyperplasia (BPH), blood in urine, kidney stones, male and female voiding dysfunction, neurogenic bladder, prostate cancer, and over active bladder.

    She excels at ureteroscopy and cystoscopy (examination of the bladder and urinary tract with a scope), endourology (minimally invasive treatment of kidney stones), laser therapy, ultrasound-guided diagnosis and treatment, urodynamic testing, and other techniques.

    To help advance her field, Dr. Gulla has conducted research. Among the topics she has investigated are voiding cystourethrogram (VCUG) testing in children for bladder and urethral abnormalities and for conditions that can lead to kidney infections.

    She has presented her research findings at the national meeting of the American Urologic Association. She also has published papers in the Journal of the American College of Surgeons and elsewhere.

    She is a member of the American Urologic Association.

    Saad Ahmad Gulzar

    Assistant Professor of Political Science
    On Leave from 10/01/2021 To 12/31/2021

    BioI am an Assistant Professor of Political Science at Stanford University. My research asks under what conditions can representative government – one that provides equality of voice and influence – improve people’s lives?

    Focusing on South Asia, I pose two broad sets of questions:
    1. Does representative government improve redistribution at the cost of policy efficiency? My work shows that broadening political representation can redistribute welfare towards marginalized communities without incurring efficiency costs. I argue that taking electoral incentives seriously holds the key to making politics work for development.
    2. How can societies transition towards more representative government? I examine long-term historical processes of transitions and their policy consequences. I also study how barriers that prevent broader political participation can be overcome both at the individual and organizational levels. My work shows that politics can be made more inclusive and that doing so can better align policy outcomes with the preferences of people.

    I work closely with politicians, political parties, bureaucrats, and government agencies in Pakistan, India, and Nepal, and strive to make these collaborations meaningful for research and policy. My work has been published in the American Political Science Review, the Journal of Politics, the Journal of Development Economics, and the Journal of the European Economic Association.

    I received my Ph.D. in Political Science at New York University in 2017, where my work received the Best Dissertation Award from the American Political Science Association’s Experiments Section.
