About Me


My research is focused on improving and analyzing security in modern real world systems with a particular interest in cyber-physical, mobile, and IoT platforms. These efforts have accumulated in studies of the SMS ecosystem, design of new protocols and techniques to help secure legitimate phone calls while preventing fraudulent ones, and various works aimed at enhancing the security of voice interfaces for modern IoT systems. My research incorporates knowledge and aspects from the fields of signal processing, vibrations, mechancial design, data science, statistics, biology and anatomy, cryptography, and networks.


I earned my Bachelor's degree in Mechanical Engineering and my Master's degree in Computer Engineering from the University of Florida in 2014 and 2016 respectively. My CV is available here.
