Po-Shen Loh Takes Action by Developing a COVID Tracking App Nov 30, 2020 | Career | As the COVID-19 pandemic rages on, there remains a thirst for solutions. In the frustrating absence of effective solutions and answers from the government, people have been developing their own. One of these proactive individuals is Po-Shen Loh, a 38-year-old mathematician who developed a contact-tracing app as one way to tackle the coronavirus. Loh spoke to Mochi via Zoom about the NOVID — a portmanteau of “no” and “COVID” — app and the team effort it takes to implement social good. Loh identifies as both a mathematician and social entrepreneur. He stated, “When you think something is possible, you go ahead and start.”
