In science we question, doubt and ask questions

before we consider accepting any statement whatsoever

I don't 'do' science these days (meaning that I don't have a lab and I don't do experiments or write research papers) but I will always think like a scientist.


Scientific method is something that is so ingrained in scientists that we question, doubt and ask questions before we consider accepting any statement whatsoever.


And since I studied philosophy of science with Professor Joseph Agassi who was a start student of Karl Popper, I believe that you can't really believe anything (including what I just said). 

Main research topics

I spent most of my scientific career studying the causes, diagnosis and treatment of bad breath.


Before that my field of expertise was hydrophobicity and adhesion of microorganisms.

Before that, nobody remembers (I did discover a microbial phenomenon as a master's student but no

one ever seemed to care).

Patents and products

My main inventions and co-inventions were:

  1. The two-phase mouthwash technology used in products in Israel,

    Scandinavia, the UK, the US and South America. 

  2. The microbial urine tester, "The Diaslide".

  3. The microbial sampler (with Ervin Weiss), the "QuadLoop".

  4. "Breathanol" antimicrobial flavor combination.
