Venture capital firm Aberdare is evolving with the times. In response to technology, policy and demographic trends that are reshaping the healthcare industry, the group on Tuesday said it is refining its investment thesis. To support its growing emphasis on “transformational health investing,” the firm also said it had hired a new partner Mohit Kaushal, an MD and MBA, who previously led investments at West Health and served as director of connected health at the Federal Communications Commission.
