Silicon Therapeutics

Technology Focus

Silicon Therapeutics simulates biological molecules using the laws of physics in order to predict behavior and interactions of drugs and their targets. The simulation is run on an advanced computing platform named “Neo”, which is a 400+ GPU cluster paired with advanced Intel Skylake processors that is housed at the MGHPCC.

Research Focus

Our innovative research combines deep drug discovery experience with cutting-edge capabilities in biology, chemistry, biophysics, and simulations.

Market Focus

Silicon Therapeutic’s’ technology is focused on small molecule drug design, focusing on previously “undruggable” protein targets. Recent work has focused on novel cancer and autoinflammatory treatments.

Social Impact

Our mission is to improve the lives of patients by designing novel medicines for challenging disease targets using our proprietary physics-driven discovery engine.
