Title: Innovations of Douglas Ewen Cameron

Introduction

Douglas Ewen Cameron is an accomplished inventor based in Brookline, MA (US). He holds three patents that showcase his innovative contributions to the field of biotechnology. His work primarily focuses on developing systems and methods that enhance the sensitivity of cells to environmental conditions.

Latest Patents

Cameron's latest patents include "Deadman and passcode microbial kill switches." This invention provides systems, methods, and compositions for rendering cells sensitive to predetermined conditions. In one aspect, cells can be made dependent on the presence of an environmental agent. Without this agent, the cells will default to expressing a death protein, leading to their demise. In another aspect, cells are designed to grow only when two or more necessary exogenous agents are supplied. If either agent is absent, the cells are killed. This aspect utilizes hybrid transcription factors to create a wide array of possible predetermined conditions. Another significant patent is for a "Synthetic hybrid receptor and genetic circuit in bacteria to detect enteric pathogenic microorganisms." This invention involves microorganisms engineered with hybrid receptors and genetic circuits. It also includes hybrid receptors that combine a CqsS polypeptide with a heterologous histidine kinase domain of a two-component system. The methods developed allow engineered microorganisms to sense and destroy pathogens effectively.

Career Highlights

Throughout his career, Cameron has worked with prestigious institutions such as Boston University and the Massachusetts Institute of Technology.
