I am an Assistant Professor with the Mathematics, Computer Science and Science Division of St. John's University's Collins College of Professional Studies.

I am the acting Program Director for the Cyber Security Systems program.

I received my Ph.D. in Computer Science from The Graduate Center, CUNY.

Prior to joining St. John's, I served as an Assistant Professor of Computer Science at IONA College teaching Computer Science and Cyber Security courses.

I have over 20+ years of industry experience working as a Sr. Systems Engineer for Time Warner Cable and Charter Communications.

My research interests include security and privacy with a focus on secure and privacy-preserving computations, location privacy and applied cryptography as well as mobile computing with a focus on location-based services, spatial databases, cognitive radio networks and delay tolerant networks.

My recent publications have been accepted in top tier conferences and journals such as ICNC, MILCOM, VTC, SIGSPATIAL, ICC, Elsevier Ad Hoc Networks and IEEE Access.

Teaching Interests

I enjoy teaching various topics on the areas of networking, network/wireless security and applied cryptography through hands-on laboratory applications.

Research Interests

My research interest topics include but are not limited to Location Privacy, Privacy-Preserving Computations, Dynamic Spectrum Access Cognitive Radio, Applied Cryptography.
