                     <h2>Research Thrust:</h2>
                     <p>The Circuits and Security Research Lab (CSRL) broadly focus on designing energy-efficient
                        and secure communication and computation for IoT devices & systems. We aim to solve
                        fundamental problems in the domain of hardware security and biomedical circuits and
                        systems, primarily focusing on innovations in the design of mixed-signal ICs and FPGAs.
