'''Dr. Riller''' is a Black Mesa scientist who presumably worked in Sector C, where he had a locker.

==Behind the scenes==
*This scientist only appears as a name on a locker in the second chapter of ''Half-Life'', ''Anomalous Materials''.
*"Riller" is a nod to Dave Riller, employee at Valve, placed there as an Easter egg.
*The name also appears as raised letters in a tunnel during the ''On A Rail'' chapter of ''Half-Life''.
