I'm in biochemistry/chemical pathology research and clinical work. I used to work in biotech/pharma back in the US, but am at an NHS hospital here. My main focus is diagnosis of rare disorders of metabolism in infants and children (and sometimes adults if there's an adult-onset variant of the disease). The pandemic definitely slowed non-essential work, but the focus was just switched to all aspects of the virus - more hands on deck to care for patients, researching the virus, trying to develop and validate new diagnostic methods, identifying useful biomarkers, and so on.
