CDAC Partner David Cahill (Illinois) is the 2015 recipient of the Yeram Touloukian Award of the American Society of Mechanical Engineers (ASME). The Toulokian Award is presented for sustained, pioneering contributions to heat conduction metrology including the 3-omega and optical pump-probe methods, which are pervasive in laboratories worldwide; and for landmark contributions on the minimum and ultralow thermal conductivity of solids.
