Dr. Laronda has developed a strong research interest in basic reproductive biology and endocrinology to feed the underlying knowledge required to develop treatments that can protect or restore fertility and hormone function. The Laronda laboratory strives to understand how the ovarian niche maintains and promotes gametogenesis, to use this information to generate in vitro models and implantable bioprosthetic ovaries as a regenerative means to support endocrine function and gamete production in patients with primary ovarian insufficiency, and to engineer endocrine organs that support sex hormon...

Dr. Perak is committed to preventing cardiovascular diseases (e.g., heart attack) by promoting optimal health from the beginning of life. Her research centers on defining and intervening at the origins of cardiometabolic function. Specific areas of focus include molecular mechanisms of cardiovascular health development (e.g., microbiome), maternal-fetal cardiometabolic health, and behavioral intervention. Her clinical and teaching interests are in preventive cardiology and noninvasive cardiac imaging.

Primary interests: Education and assessment of medical students and residents, curriculum development, Otoscopy, Ear disease, Ophthalmologic emergencies, Orthopedic injuries

Over the course of his training Dr Nolan developed a strong interest in the complex relationship between autoimmunity and immunodeficiency. As a clinician his goal is to more rapidly and more accurately diagnose autoinflammatory and immune dysregulatory syndromes, and in so doing help identify effective treatments for patients with these exceedingly rare conditions. He hopes to advance translational research in this rapidly developing field as a clinician with a strong background in immunology bench research. His additional interests include general pediatric rheumatology and medical education.

Throughout my career, I have studied the intersection of medical education, quality, and clinical effectiveness in high acuity situations. In the course of this work, I have developed clinical practice guidelines, co-founded a multidisciplinary critical care simulation curriculum, and spearheaded numerous quality improvement projects aimed at protocol development and communication in the pediatric intensive care unit. My current interests include exploring human factors in high stress environments, particularly related to clinician wellness and resilience.
