Alexandrer Lekkas completed his undergraduate studies at the Department of Physics, University of Athens. During his dissertation he developed a heartbeat detector using photodiodes and transistors. Then he attended the postgraduate Program of Biomedical Engineering, University of Athens. His research activities were focused on the design and construction of data acquisition systems, digital signal processing (sampling, spectral – frequency analysis, Fourier and z transformations) and the modeling of complex systems (with application of nonlinear dynamic parameters). Furthermore during his work experience he became familiar with handling complex computational devices (hardware and software). In his work with Fasmatech AL is in charge of managing computing devices for ion optical simulations and oversees much of the theoretical study and simulation of ion trajectories in gases, focusing on detailed highly sophisticated models for ion-molecule collisions.
