M.Sc., Under the Direct Ph.D. track, titled: Molecular logic: A biomolecular computing system capable of intelligent deductions and query answering.

I am a PhD student of Prof. Ehud Shapiro at the Departments of Computer Science and Mathematics and Biological Chemistry in the Weizmann Institute of Science, Rehovot , Israel 76100.
Laboratory for Biomolecular Computers

Molecular computing devices have the clear advantage of small size, as well as the ability to interact directly with their biological surroundings due to their inherent biological nature, therefore holding the promise to be used in future biological and medical applications.

Biomolecular Computing   Simple molecular logic programs
Computation is an abstract process that may have multiple physical implementations. Molecular computation is an attempt to harness the power of molecular biochemistry to perform computation. As in the early days of electronic-based computers, different computational notions are inspiring the emergence of new, biochemically-based computing devices. These computing devices made of biological molecules hold the promise of interacting with the biological environment in future biological and medical applications.   We've designed and implemented an innovative molecular logic system. Our simple molecular logic programs consist of three types of statements: facts, rules and queries. Tiny water drops contain the molecules encoding the different facts and rules. When added a molecular query, a chain process of molecular deduction starts and in the case of a positive answer, the water drop emits green light exhibiting a "Positive" answer.
