Jason Zucker, Noémie Elhadad, and Nicholas Tatonetti are all part of a research collaboration at Columbia University called CovidWatcher (covidwatcher.org). CovidWatcher is a citizen-science tool to identify hot spots and the needs of communities during the COVID-19 pandemic. Participants can take part by taking surveys online (covidwatcher.org) or by downloading the CovidWatcher app on iOS App Store (https://apps.apple.com/us/app/covidwatcher/id1504295590)

• Jason Zucker, MD: I’m an Instructor in Medicine in the Division of Infectious Diseases at the Columbia University Irving Medical Center/NewYork-Presbyterian Hospital (CUMC/NYP) and a core faculty member at the Centers for Disease Control funded NYC STD Prevention Training Center. Prior to COVID I worked as an adult and pediatric infectious disease physician and researcher improving the cascade of care for HIV and STI prevention. Now I spend my time taking care of patients and working on studies that can expand our knowledge of COVID-19.
• Lawrence Purpura, MD: I am an infectious diseases clinical fellow at the Columbia University Irving Medical Center and an ICAP post-doctoral research fellow at the Mailman School of Public Health. Prior to moving to New York 3 years ago, I was an Epidemic Intelligence Service officer at the Centers for Disease Control. I specialized in preventing the sexual transmission of Ebola virus in West Africa, but also responded to other outbreaks, including Rift Valley Fever and Hanta virus. More recently, I have been working clinically as an infectious disease physician, in addition to research involving HIV and STI prevention.
• Pat Stone, PhD, RN: I’m the Centennial Professor of Health Policy in the School of Nursing. I have been studying best practices in infection prevention and control in various healthcare settings for the last 20 or so years. The last 8 years, our team has been mainly focusing on infection prevention and control in nursing homes and how nursing homes across the country manage infection symptoms with advance care planning/palliative care for residents at the end-of-life. With nursing homes being a catalyst for COVID-19 cases in many communities, the lessons we are learning can help nursing home staff best manage the pandemic as well as help families of elderly nursing home patients think through care goals.
• Noemie Elhadad, PhD: I am a professor in biomedical Informatics and computer science at Columbia University Irving Medical Center. My research is at the intersection of machine learning, medicine, and technology. My students and I build AI tools that help healthcare providers in their activities and citizen-science platforms to learn from the experience of patients.
• Nicholas Tatonetti, PhD: I’m a professor in the Departments of Biomedical Informatics, Systems Biology, and Medicine at Columbia University. I lead a small but nimble group of data scientists working on ways to use health records and observational data to make biological discoveries about protein function, genetics, and disease mechanisms. My group is conducting COVID-19 research to uncover unknown risk factors,i dentify new therapeutics, and model patient outcomes. Lastly, I’m hosting a weekly videocast, called The C19 Weekly, where I discuss the latest data science and bioinformatics-oriented COVID-19 research papers.
