Mr. Ananya Srivastava | Interaction Simulations | Best Researcher Award
Researcher | Hahn-Schickard-Gesellschaft | Germany
A project leader and scientific researcher specializing in MEMS-based acoustic and photoacoustic sensors with proven expertise in project management, cross-functional R&D, and technology transfer, this researcher has led EU and industry-funded projects resulting in patents, publications, and novel gas-sensing platforms while bridging academia and industry. His work focuses on process and layout designs, FEM simulations, sensor packaging, systems and control engineering, and multidisciplinary product development. As a project leader and scientific researcher in Acoustic MEMS at Hahn-Schickard-Gesellschaft in Villingen-Schwenningen, he has contributed extensively to project management of international collaborations, research and development in MEMS and acoustic MEMS, design of experiments, analytical modeling, numerical simulations, readout electronics, rapid prototyping, sensor testing, laboratory management, CAD-based prototyping, MEMS process flow and layout design, data analysis, scientific writing, partner communications, and student supervision. Earlier contributions include designing and optimizing MEMS-based inertial sensors for crash-test applications, developing readout electronics and test setups for three-dimensional acceleration sensors, and conducting FEM analyses during his master thesis work. His industrial experience at Robert Bosch GmbH strengthened his expertise in silicon-based MEMS acceleration sensors, communication protocols, measurement equipment, automation of experiments through programming in C, MATLAB, and LUA, and inter-departmental collaboration in sensor testing and troubleshooting. Additional research work at IMTEK, Albert-Ludwigs-Universität Freiburg, involved PCR system development, electronics testing, thermal cycler design with LabView and Arduino, fluorescent detection metrology, and component assembly, while his role as cleanroom lab tutor included photolithography, etching, patterning, and physical vapor deposition.
