EHSRC investigators wear many hats, both inside and outside of their membership with the Center. Many have been active contributors in response to the emerging questions and needs during the COVID-19 pandemic. As experts in the fields of respiratory health, industrial hygiene, engineering, aerosol science, patient care, vaccine development, and community engagement, they are tirelessly offering up their expertise to the cause by developing new technologies and interventions, working the front lines of patient care, delving into the complex infrastructural challenges, and advising governmental authorities and the general public. We are proud to count them among our members and pay tribute to their ongoing efforts in this fight.
