In mathematics, a random walk is a random process that describes a path that consists of a succession of random steps on some mathematical space.
An elementary example of a random walk is the random walk on the integer number line \mathbb Z ...

shared the Washington Academy of Sciences award for their contributions in Mathematics. Established in 1939, this award recognizes noteworthy accomplishments by young scientists (40 years of age and under). In May 2010, the NIH held a symposium entitled "Random Walks in Biology and Beyond", in honor of Weiss's 80th birthday and recent retirement. In July 2010, at the Mexican Meeting on Mathematical and Experimental Physics, Weiss was awarded the Leopoldo García-Colín-Scherer Medal. This medal has been established in 2001 and awarded every three years to recognize outstanding international scientists for their contributions to the development of science.
Research
Main contributions of Weiss are in the theory of random walks, in particular, the development of the Continuous Time Random Walk (CTRW). The original article that introduced CTRW has been cited more than 2000 times, and this work found applications in many different fields. In the summer of 2017, the European Physical Journal B (Condensed Matter and Complex Systems) is planning to publish a Special Issue: "Continuous Time Random Walk: fifty years on", which celebrates 50 years since the appearance of this seminal paper. The submissions to this issue are accepted until 31 May 2017
EPJB. Weiss himself has made many significant contributions in applying the CTRW framework in the areas of optical imaging, financial market theory, and other fields. In recent years, his research in optical imaging was focusing on the application of CTRW in the case of the spatially anisotropic optical properties.
Weiss also used the renewal theory techniques to analyze the traffic flow, aiming to understand the problems of traffic delay and congestion.
Besides his contributions in applications of CTRW to optical imaging, made also significant contributions in general medical research, and has worked extensively on
crystalline lattices and their properties.
