Chief Residents

Nicholas Bosch


I grew up in the San Francisco Bay Area just outside of Napa, working in the vineyards in the summer and filling every other waking moment playing sports. I received my undergraduate degree in Marine Biology from UC Davis (Go Ags!) and then went to medical school at NYMC after I realized that my life can’t revolve around just soccer. At NYMC, I developed a passion for taking care of at-risk populations and also met my future wife. We couples matched at BUMC in 2012, excited to train and develop at an institution with such a rich history of caring for the underserved. Now, as one of the chief residents, I love my new role in education, administration and mentorship and look forward to a future career in academic pulmonary & critical care medicine. Outside of work, I like doing anything active or outside, as I just don’t like to sit still!

I grew up in Washington, DC, and enjoyed rowing along the Potomac River during high school. I moved up to New England to attend college at Harvard College and have remained a New Englander since then, attending Brown University for medical school. My interest in medicine and international health allowed me to venture to Botswana for anthropological thesis work during college, and to American Samoa during medical school for a study on gestational diabetes. Between college and medical school, I worked as a research assistant to the surgeon and writer Atul Gawande, performing background research for his New Yorker articles and books. I was introduced to the world of quality improvement through his surgical checklist, and have pursued the Quality Improvement and Patient Safety pathway at Boston Medical Center during residency. I am excited to serve at the Chief Resident in Quality Improvement and Patient Safety this year. I love living in Boston’s vibrant South End, running on the Esplanade by the Charles River, and traveling.

I grew up in the suburbs of Chicago but have since lived everywhere from Alaska to Atlanta and San Francisco to Boston. After completing my undergraduate studies at Caltech I studied public health at UC Berkeley and spent a year working at the Centers for Disease Control. I then moved to Boston to do consulting in health and environmental issues. When I realized my true passion was medicine, I went back to school at Case Western’s School of Medicine and then returned to Boston for residency at BMC. BMC stood out as having a fascinating patient population from around the world and a well-established Primary Care Training Program. When I’m not processing swaps or planning morning reports, I enjoy baking, playing with my daughters and reading the New Yorker.

I grew up around the world: born in Australia, then lived in Bangladesh, Nepal, England and Switzerland before moving to the US to pursue residency. I attended medical school at the University of Oxford, UK and took opportunities in the US to pursue research and clinical elective opportunities. I moved to Boston Medical Center due to the diversity of the patient population and pathology, as well as the amazing environment that was fostered by the residents, attendings and program leadership. I am honored to have the opportunity to contribute to the development of a great residency program, and learn from and teach the house staff. In the future, I plan to pursue a career in academic cardiology. Outside of work, I enjoy ballroom and Latin dancing, and traveling around the world.

Born and raised in Queens of New York City, I envisioned myself to be a lifelong New Yorker.  After starting my medical training at the combined B.S/M.D program at the Sophie Davis School of Biomedical Education in Harlem, I transitioned to Stony Brook Medical School for my clinical years. Through these formative years of my education, I came to seek out the challenges of medical care in the underserved areas of the city. I conducted research in substance abuse in this vulnerable population, working with Harm Reduction programs in Harlem and the Bronx as well as the Municipal Addiction Services in Amsterdam, Netherlands. When looking for residency programs, I wanted to practice medicine at an institution that provided me with the unique challenges of caring for the underserved. Boston Medical Center in this respect, was a great match. Though it was not easy leaving New York City, I have been thrilled with my training as well as life in Boston. Outside of medicine I enjoy spending time with my family, following my favorite sports teams and watching documentaries. After my chief resident year, I plan on pursuing a fellowship in cardiology.

I grew up in the northwest suburbs of Chicago and first left home to pursue a premed track at Harvard College.  Upon graduating, I traveled back to my home state to begin medical school at the University of Illinois in Chicago.  I fell in love with the diverse patient population in Chicago and became determined to pursue a similar clinical setting for my residency training.  Upon interviewing for internal medicine at BMC, I realized this was the place for me.  I moved back to the east coast with my husband and we’ve both been Boston fans ever since.  Three years of residency flew by and after graduating in 2014, I left Boston to start my first year of nephrology fellowship at Johns Hopkins.  I am fortunate and honored to be back in Boston for one (short) year as a chief resident.  When I return to Baltimore, I plan to complete my three year fellowship in nephrology and pursue a Master’s of Science with a focus on clinical epidemiology.  My medical career so far has inspired me to work in a large academic medical center that serves the same, diverse patient population that BMC sees on a daily basis.  In my spare time, I enjoy reading, cooking, international travel, reposing on the beach, staying active in the outdoors, and spending time with my wonderful husband

I grew up in Minnesota, where I spent my childhood playing Minnesota specific games like “duck duck grey duck”, saying things like “oh yah sure you betcha” and “pop” (instead of soda), and going to the great Minnesota get together (ie- The Minnesota State Fair). I initially came to Boston to go to Tufts as an undergraduate, and went back to the University of Minnesota for medical school. However, I loved my time in Boston when I was in college, and wanted to come back to complete my residency training. I chose Boston Medical Center because of all the amazing people who work here and come here for their care. I am looking forward to my year as chief resident this year, and am planning to pursue a fellowship in pulmonary and critical care. Outside of work, I like to spend time with my family, run, and try new foods!
