Personal Information

I am a fifth year PhD student in the Department of Computer Science at Purdue University, which is located in the state of Indiana (USA). My advisor is Aniket Kate. Before moving to Purdue University in August 2015, I started my PhD studies at Saarland University in April 2013 under the supervision of Aniket Kate.

I have been an intern research at IBM Research - Zurich (Switzerland) in 2017 under the supervision of Christian Cachin; at Ripple (USA) in 2016 under the supervision of Stefan Thomas; and at Philips Research Europe (The Netherlands) under the supervision of Oscar Garcia-Morchon and Rafael Marin-Lopez. I received my bachelors and masters from University of Murcia (UM) (Spain) in 2011 and 2013 respectively.

Research Interests

Currently, my research focuses on the areas of security, privacy and reliability of emerging online payment networks:

I am also interested on topics related to security in emerging network scenarios:

  • Network access control in distributed scenarios (e.g., eduroam).
  • Bootstrapping and key management in constrained networks (e.g., Internet of Things)
