Joseph Nguyen, MPH
Biostatistics Core at Hospital for Special Surgery
New York, NY

Mr. Joseph Nguyen, MPH is the Director of the Biostatistics Core at Hospital for Special Surgery in New York, NY. Born and raised in Kansas City, MO, Mr. Nguyen is a first generation American and the proud son of Vietnamese refugees. He was awarded the inaugural Bill and Melinda Gates Millennium Scholarship and earned his bachelor’s degree in chemistry from Rockhurst University in Kansas City, MO. Following his undergraduate studies, Mr. Nguyen spent a year volunteer teaching in St. Louis, MO.  In 2007, Mr. Nguyen completed his Master of Public Health program from Saint Louis University’s School of Public Health with a concentration in Epidemiology and Biostatistics. He subsequently moved to New York City to work for the New York City Department of Health and Mental Hygiene in their Bureau of Communicable Diseases.

After a short tenure at the DOHMH, Mr. Nguyen transitioned his work from in the public sector to focus on orthopaedic clinical research at HSS. At HSS, he has provided comprehensive methodological and statistical support in the area of musculoskeletal research, overseeing research projects from development to publication. This support provided came in the form of development and execution of study design methodology, statistical analysis planning, data management structure, and written contributions for abstract, manuscript, and grant submissions. Since 2014, Mr. Nguyen has served as the Director of the Biostatistics Core, managing and mentoring an integrative team of epidemiologists and biostatisticians that provide methodological, data, and statistical support to facilitate, encourage, and maintain the highest of quality standards of clinical research at HSS. The area of orthopaedic sports medicine has been an area of interest for as long as he can remember. His personal experience as a multi-sport athlete in high school and previous work coaching varsity high school teams during his time in St. Louis has made him appreciate the physical and mental components that are involved in the conditions and procedures he studies. While his personal research interest is in sports medicine, Mr. Nguyen has been co-authored on many publications throughout the field of orthopaedic medicine. Outside of his time at work, Mr. Nguyen enjoys spending time with his three brothers, two sisters, and his nieces and nephews as much as he can see them. Mr. Nguyen is married to his wife Brie, and together they enjoy their time with their dog and have a love of food and travel.
