Last, with the emergence of Covid-19, Sonda helped to create a plan that allowed patients to maintain their essential MS infusion therapies safely. She made sure the clinical research program at MIND was able to continue to conduct study visits, in an effort to not delay the study of emerging treatments for this chronic and often progressive disease.
