The remarkable pace of drug discovery by biotech and pharma owes much to the contributions of venture capitalists. Indeed, real-world conditions that threaten conventional funding sources will likely render venture capital an ever more critical source of support for drug discovery. The acuity of venture capitalists will become more critical as well. In our discussions of investment opportunities, I have been impressed by the depth of knowledge of the RiverVest team, particularly in the areas of immunology, molecular biology, and medicine, and I am excited to contribute my expertise as a member of the Scientific Advisory Board.
