Dr. Nielsen was awarded the prestigious Grant for Emerging Researchers/Clinicians Mentorship (G.E.R.M.) in 2020 by the Infectious Diseases Society of America, highlighting his efforts to expand antimicrobial stewardship to the outpatient setting under the guidance of Fritzie Albarillo, MD at the Stritch School of Medicine of Loyola University Chicago, where he graduated in 2023 with his MD and MPH degrees.  The Illinois Department of Public Health invited them to present their research at the IDPH Summit on Antimicrobial Stewardship, which was recently published in the journal Antimicrobial Stewardship & Healthcare Epidemiology.
