Our residents!


Ruth Cadet, MD, MPH

Position: PGY-1

Undergraduate: Brown University
Graduate (MPH): Columbia University
Medical School: Jacobs School of Medicine and Biomedical Sciences at University at Buffalo

Ruth was born in Brooklyn NY and grew up in northern NJ.  She attended college at Brown University concentrating in Sociology.  At Brown, she discovered her love for public health and after graduating she decided to get her MPH in Epidemiology at Columbia University.  While pursuing her MPH she earned a position working with NYC Health + Hospitals, the public safety net health care system of New York City.  She started there as a data analyst and eventually went on to manage several initiatives focused on improving community health and chronic disease management.  Though she loved her work, she knew she wanted to provide direct care to patients and so she decided to pursue medical school at the University at Buffalo. There she learned about Med-Peds and knew she found her calling.  The reasons she wanted to go into Med-Peds are the same reasons why she wanted to come back to Brown for residency. She knows at Brown she will receive great clinical training in caring for a diverse patient population while also being able to pursue work in public health in the US and abroad.  In her free time, she likes connecting with family and friends, reading (or really listening to audiobooks at this point), playing tennis, and playing piano & guitar. She is also attempting to cook and bake more with varying degrees of success.

Tamara Lhungay, MD

Position: PGY-1

Undergraduate: University of Colorado
Medical school: University of Colorado School of Medicine


Tamara grew up in rural Hygiene, Colorado. She attended the University of Colorado where she graduated with honors with a B.S. in Biology and dual minors in Interdisciplinary Research Methods and Health Humanities. At the University of Colorado School of Medicine, she developed an interest in oncology and survivorship, as well as in serving refugee and migrant populations (her father is a Tibetan refugee and her mother is the daughter of Dominican and Jamaican immigrants.) Her research was mainly focused on quality improvement and oncology, but her guiding star remained the humanity within medicine. Wanderlust struck, and after crisscrossing the country, Tamara fell in love with New England, and Brown instantly felt like home because of the warm and genuine people, paired with academic excellence and a supportive and growth-focused culture. In her free time, Tamara enjoys hiking, skiing, (or any outdoor activity), and will say yes to most adventures. When she must stay indoors she enjoys board games, crocheting, and spending time with her two cats, Remi and Theo.


Cameron Ulmer, MD

Position: PGY-1

Undergraduate: Northwestern University
Medical School: Rush Medical College of Rush University (AOA, GHHS)

Before starting medical school, he worked for a year as a phlebotomist. At Rush, Cameron was involved in medical education efforts including TAing, tutoring, and curriculum development, and sat on the committee addressing student mistreatment. Apart from medicine, he loves to volunteer with Camp Kesem, even advising Brown’s camp in 2018! Brown’s Med-Peds program blew Cameron away with the warmth of the residents and faculty along with the strong categorical training programs, and he is thrilled to return to New England to continue his training. In his spare time, he enjoys running, hiking, baking, trying new and adventurous foods, and playing and watching sports (huge Northwestern fan).


Madeleine Ward, MD

Position: PGY-1

Undergraduate: Georgetown University
Medical School: Georgetown University School of Medicine (AOA)

Madeleine grew up in Atlanta, GA. After graduating valedictorian from high school, Madeleine ventured north to spend her days on the hilltop of Georgetown, where she majored in biochemistry and minored in art history. Knowing her passion for medicine and her love for Georgetown, she chose to apply to the early assurance program for medical school and was accepted at age 20. As she transitioned to a new chapter in her Georgetown adventures at medical school, Madeleine decided to explore the intersection between art and medicine. She created a research project to look at how art education at the National Gallery of Art in DC can improve medical students’ communication skills. She hopes to continue learning more about arts and medicine at Brown. The Med-Peds Program at Brown stood out among the rest because of the people. She absolutely loved everyone she met and felt extremely welcomed. She also appreciated the reputation of excellent clinical training in both internal medicine and pediatrics. As an added bonus, Madeleine also realized the incredible extent of art and dance at Brown and in the surrounding community. At this time, Madeleine is currently undecided on her career path, but is interested in the Clinical Educator Track and potentially a dual adult/pediatric fellowship. She is excited to live in Providence and explore all the amazing food. In her free time, Madeleine enjoys crafting, board games, dancing, cooking, and outdoor activities.

Fritz Siegert, MD

Fritz was born in Nevada, lived in Arizona and Kentucky, and finally settled on Boise, Idaho with his parents and two younger brothers. He attended Whitman College and graduated with a double-major in Philosophy and Biochemistry, Biophysics, and Molecular Biology (BBMB). One year out of college found Fritz back in Boise working as a medical scribe, tutoring high school students in science and math, and working as an intern at the Basque Cultural Center (little known fact, Boise has a huge Basque population). After that, Fritz spent a year teaching middle school science in Botswana as a Princeton in Africa Fellow. He then attended medical school at the University of Washington in Seattle. During that time he enjoyed organizing “community-based research” looking at free-health clinics and tobacco cessation counseling. He additionally held leadership positions in student government, the Health Equity Circle student advocacy group, and conducted community outreach in Kenya. From 2017 to 2018, Fritz researched pediatric sickle cell anemia in Uganda as a Fogarty Global Health Scholar. With strong interests in global health, policy, and medical education, Fritz was impressed with Brown’s commitment to global health equity, academic rigor, mentorship, and friendly residents. Providence also fondly reminds him of Boise (though with less of a potato emphasis). He loves the outdoors, aspires to one day learn how to play the harmonica, and makes a mean frittata.

Vivian Shi, MD

Position: PGY-3

She majored in Molecular, Cell and Developmental Biology at UCLA, followed by medical school at University of Maryland. Her passion lies in teaching and enhancing community health literacy.

Roger Auth, MD

Position: PGY-4

Undergraduate: University of Maryland, College Park
Medical School: University of Maryland School of Medicine

Roger was born and raised a Maryland Terrapin and prior to residency had never lived outside of his home state. What drew me to Rhode Island and Brown were many things: the phenomenal leadership and experience of our faculty, evidence based cultures of our medicine and pediatrics departments, flexibility and encouragement to pursue non-medical ambitions, and the collaborative and motivating personalities of my med-peds family.

Living in Rhode Island has kept me rooted to the things that make me who I am, amidst what most would argue is an incredibly challenging time of life, residency. At Brown I’ve had ample time for the things that are at the core of my personality: my wife, family (including my cat), friends, and hobbies, including: surfing, paddle/kite/skate/snowboarding, camping, hiking, and playing various musical instruments both well and badly.

Professionally, I am interested in a career in Pulmonary and Critical Care medicine. I am currently involved in clinical research related to both adult and pediatric pulmonology with a focus on improving inpatient care for individuals with cystic fibrosis. This research has been presented at the North American Cystic Fibrosis Conference. I have secondary interests in palliative care and improving resident utilization of point of care ultrasound. I have felt tremendously supported by the faculty at Brown and my colleagues with whom I engage in these research projects and clinical endeavors.

Post-residency plans: Pulmonary & Critical Care Medicine Fellowship at Brown University
