Dr. Lele is part of the Electrical and Computer Engineering practice at Exponent with a focus on failure analysis and safety design reviews of electrical and electronic systems. She has expertise in design and quality review of household and commercial products, automotive electronics and industrial systems with a focus on system safety and redundancy.
Dr. Lele’s work at Exponent involves extensive battery related analyses & literature review, root cause investigations and testing of products for accelerated ageing of batteries and other electronic components. Her work also involves hardware and software testing of automotive systems such as the electronic braking system, cruise control, hybrid control system, throttle control system that are part of conventional and autonomous vehicles. On account of her past work experience, she specializes in circuit design, use of electrical laboratory equipment and simulation tools for PCB/IC design, and numerical modelling.
Prior to joining Exponent, Dr. Lele was involved in board level and component level functional testing & verification of WDM telecom devices (Erbium Doped Fiber Amplifiers) using NI TestStand and LabVIEW at ADVA Optical Networking. As part of the design team at AMD, Inc. (Advanced Micro Devices, Canada), Dr. Lele designed analog sub-circuits for the DisplayPort AUX/I2C interface with GF’s 20nm and 14nm technology and is proficient in Cadence, Synopsys, Apache tools.
Dr. Lele has worked on integration of control circuits for power relays with GE Multilin during her Ph.D. The prototype system she developed for detecting voltage and current disturbances in high-voltage power distribution lines employed piezoelectric transformer in combination with Hall-effect sensor with an integrated signal processing unit. Prior to graduate studies, at Siemens (India), Dr. Lele’s work included design improvisation of ‘25kVA underslung type coach converter' typically used in air conditioning systems in Indian Railway coaches and development of the 500kVA converter for power car of super-fast trains.
