Niv Sarig PhD
I am a mathematician with a PhD granted from the department of Mathematics in the Weizmann institute of science.
I am serious, thorough, with excellent interpersonal skills, strong work ethics and a desire to bring and combine a vast mathematical knowledge, superb research and teaching skills to the real world
(HiTech\Engineering, Economics\Investments, Mathematical research and consulting etc...)."
As a senior algorithm developer at Optibus inc. I research and develop cutting edge optimization algorithms in Optibus SAS product. We are helping public transportation operators to reduce OPEX and improve operations and transportation planning. Optibus is a young Israeli startup expanding rapidly, its market share keep on growing and growing (and the sky is the limit in that aspect) thanks to our cutting edge algorithms that win competitors in quality and in performance (Big time!).
Developing optimization algorithms in Optibus SAS product, accelerating calculations, and dealing with memory and other infrastructure limitations while keeping the algorithm best achievements are part of my daily practice.
As a path finding group member at Nova I was part of an exclusive team of ~10 PhD Colleagues all are in physics\engineering. As the only Mathematician I brought a different point of view to algorithms, modeling and general approaches on the new aspects being researched in the team (being led by Nova's CTO).
Accelerating extrapolation and regression in multi-dimensional libraries, modeling physical systems (optics, reflectometry, spectroscopy, nano-metric scale metrology) and solving inverse problems were the main tasks I was being involved in.
I wake up every day full of energy for a new and interesting day in Nova. Wait for the new challenging and important tasks and problems I will find during my research to attack, dive in and finally solve.
Along side, since I find it highly fulfilling and interesting, I dedicate part of my time for teaching advanced Mathematical courses in the Academy, especially at the Weizmann institute of Science.
