2018 – 2020 Fellows

Joshua Herigon, MD
Josh trained in Pediatrics at Children’s Mercy Hospital in Kansas City, Missouri. In addition to being a clinical informatics fellow, he’s also currently training in pediatric infectious diseases at Boston Children’s. Josh initially became interested in informatics while working in antimicrobial stewardship research prior to entering medical school. He utilized the Pediatric Health Information System–a database composed of millions of encounters from 45 tertiary care pediatric hospitals–to examine national trends in antimicrobial use in order to identify areas to target stewardship efforts. He also took a year off of medical school to develop an iPhone app that put local clinical practice guidelines in clinician’s hands at the point of care. In fellowship, Josh hopes to use cutting edge information technologies to improve the assessment and treatment of infectious diseases. He specifically hopes to apply these tools to improve appropriate antimicrobial use both in the inpatient and outpatients settings.

2019 – 2021 Fellow

Peter Hong, MD
Peter trained in Pediatrics at the University of Texas Southwestern Medical Center and Children’s Health System of Texas in Dallas, TX. One of his first steps toward informatics took place through the clinical use of an enterprise data warehouse to increase pneumococcal immunization rates in patients with immunocompromising conditions. To elucidate factors contributing to immunization status in this population, Peter interviewed families, nurses, front-desk staff, transplant coordinators, practice managers, and physicians. After the identification of several opportunities to improve communication and processes using health information technology (HIT), he became galvanized by informaticians whose expertise facilitated improved immunization rates, not to mention Peter’s vision for streamlining care management and quality.

While serving in the role of chief resident, Peter coordinated multidisciplinary groups to streamline documentation practices and electronic health record use in order to facilitate trainee education and improve clinician satisfaction. Peter is passionate about wellbeing and looks forward to a career in which he can transform the patient and provider experience through cognitive informatics discoveries and implementation. Through dual fellowship in Clinical Informatics and Pediatric Hospital Medicine, Peter aims to gain a deeper understanding of medical economics, quality improvement, implementation science, and health system leadership.

2020 – 2022 Fellows

Mara Alexeev, MD, MPH
Mara completed a combined pediatric residency and masters of public health at Kaiser Permanente in Oakland, CA and the University of California, Berkeley, respectively. Afterwards she worked as an outpatient pediatrician in Maui, HI and as a school physician in New York City. While at home as a full-time mom following the birth of her son, she learned how to program in R and stumbled upon the field of clinical informatics. Prior to that happy discovery, she had worked on many different quality improvement projects, EHR collaborations, and workflow analyses, so finding the clinical informatics community was a professional homecoming. Immediately prior to starting fellowship, Mara was the Pediatric Chief Resident at Memorial Sloan Kettering in New York City, and she hopes to use her oncology experience in her clinical informatics career to help improve outcomes in pediatric cancer. She is also interested in how laws and policies affect the use of medical technology and how electronic health records are implemented around the world. Outside of work, Mara enjoys reading, learning languages, and spending time outdoors with her family. She is also on the committee for the R/Medicine Conference.

Lily Payvandi, MD
Lily trained in Family Medicine at Drexel University in Philadelphia. Her research in residency focused on geo-analytics using EHR and census tract data to study social determinants of health. She additionally analyzed EHR log data to study physician task burden. Lily is drawn toward patient advocacy and student mentorship, and served as Resident Representative to the Pennsylvania Academy of Family Physician’s Board of Directors. She is enthusiastic for Fellowship to lend her an innovative, interdisciplinary lens to improve primary care.
