    Collapse overview
    Dr. Mónica E. López has experience in all aspects of neonatal and pediatric surgery, with special training and clinical interest in minimally invasive and laparoscopic surgery, anorectal malformations, and gastrointestinal disorders, including surgical management of inflammatory bowel disease and endocrine surgery.

    Dr. López’s research interests focus on the design and implementation of retrospective and prospective pediatric surgical clinical outcomes studies. She regularly mentors residents and students in clinical research. She is also investigating the development of clinical research trials that lead to the implementation of evidence-based practice guidelines in the management of common pediatric surgical diseases and improved patient outcomes. She is currently pursuing a Master of Science degree in Clinical Research at The University of Texas Medical School at Houston.

    PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
