Research Areas: Computer Systems, Complexity, Biomolecular Networks RAHUL SIMHA Department of Computer Science The George Washington University Washington, DC 20052 simha@gwu.edu 202-994-7181
Motivation: Computer Security What hackers do: Code understanding: to duplicate, steal ideas, prepare attacks Code tampering: to circumvent checks, cause attacks Others: data tampering, authorization attacks, buffer-overflow I can understand the code Now I can modify the code
Software Security/Protection • Computer security research • Crypto, protocols, policy, intrusion detection • Related areas: data mining, signal processing, networking … • Our approach: • How can compilers be used to protect software? • Exploit reconfigurable (FPGA) hardware • Tools to manage security/performance tradeoff. • Collaboration with: Bhagi Narahari (CS) Secure compiler Source code Secure executable
Biomolecular Networks • Hypoxia network • 23 molecules (e.g., HIF, PH, VHL) • Unusual effect: sharp response to oxygen • Our goal: explain using mathematical (ODE) models • Boolean network models: • Gene-regulation network • Explore fundamental properties • Collaboration with: Frank Turano (Bio), Chen Zeng (Physics)
Other research interests • Complex Systems • Phase transitions in complex systems • How and why does complexity arise? • Embedded Systems • Sensor networks, databases • Energy consumption (low power applications) • Smart-home medical applications • Patient monitoring • Robotics for in-home care
