~$ ./about

Hi, I'm Esteban 'Steve' Rangel, a Ph.D. candidate in the Electrical Engineering and Computer Science department at Northwestern University under the supervision of Professor Alok Choudhary and a member of the Center for Ultra-Scale Computing and Information Security (CUCIS). I'm also a member of the Cosmological Physics and Advanced Computing (CPAC) group in the High Energy Physics division at Argonne National Laboratory where I work primarily on developing scalable analysis tools for cosmological N-body simulations.
